Which new investment to be funded by a wide 13 million and R & D team to Fosugufen invested 500 million yuan, according to extensive research and development results of new revenue to invest 40%, Fosugufen and R & D team is divided into a total of 60%.

Li-ion battery integrated into the flight program faces five major risks

Integrated into the fly (002 190) has issued a notice of private placement fund-raising projects face the risk of making the top five tips. Previously, integration into the flight have been disclosed private placement program, the company intends to fund-raising not more than 1.02 billion capital increase will be used in aircraft construction lithium ion battery project.

Notice that the lithium-ion battery market capacity project faces risks, construction risks, competition risks, technical risks and risk management. Lithium-ion battery are high-tech products, the market is still in growth stage application stage.

Meanwhile, the main products used in battery cathode material lithium iron phosphate process due to technical and other reasons, few domestic producers, production capacity is limited. Although the relevant domestic enterprises to continue this increased investment, but completed the construction of the project and after it reaches its design capacity, lithium iron phosphate cathode material development of the industry may still limit the supply of raw materials in the aircraft lithium, and its business to a certain impact.

Friends called for battery recycling to protect the environment

As wireless technology to lower prices, more and more popular wireless product. But because the power supply for technical reasons, the wireless mouse must be equipped with batteries, with the increased use of battery recycling on the fore, some enthusiastic early users called for battery recycling systems make the trip, let's take a look at our wonderful friends with the analysis.

Pollution and waste batteries process has become the social focus of most environmental concern. State Environmental Protection Administration of Science, Technology and concerned that with our type of battery, production and use continues to expand, the number and types of used batteries has also increased. Used batteries contain mercury, lead, cadmium, nickel and other heavy metals and acid, alkali and other electrolyte solution, and the ecological environment of the human body have different degrees of damage. It is understood that one of the ecological environment on human health and harmful, included in the list of hazardous waste control of waste batteries are: mercury cells, mainly mercury oxide batteries; lead-acid batteries; cadmium batteries, nickel-cadmium battery mainly.

Today, electronic waste disposal has been the focus of public attention, the majority of users are also welcome to offer words offer, a better environment for our contribution to a force.

5 trillion stimulus to guard against the new energy industry overcapacity

5 trillion stimulus to guard against the new energy industry overcapacity

Industrial development in China's history, "step forward" and "excess capacity" is always go hand in hand, will invest in the next 10 years, five trillion yuan effort to develop the emerging energy industry has been true. Restructuring of the national economic restructuring, development of low environmental-friendly industry in the context of the prospects of new energy industry is looking on. However, how to balance "speed" and "quality" of the relationship between, it has been a problem.

Policy: the emerging energy industry planning has basically taken shape

Economic situation in the first half of the national energy conference, the National Energy Board Planning Division, said Jiang Bing, the emerging energy industry planning has become a mature manuscript, is preparing to report the State Council. The plan proposes that, from 2011 to 2020, will increase total investment of 500 billion yuan, 1.5 trillion annual output value will increase.

Familiar with the previous "new energy plan" is different from the National Energy Board will be planning the final name as "emerging energy industry planning." Jiang Bing explained that the plan includes not only wind energy, hydropower and nuclear power, including the upgrade of traditional energy sources.

Planning, not only includes the advanced nuclear power, wind, solar and biomass energy resources in these new development and utilization of traditional energy sources will also be important to upgrade the first change, including clean coal, smart grid, distributed energy, new car energy and other industrial application of technology specific implementation of the path, the scale of development and major policy initiatives. In order to achieve non-fossil energy sources by 2020 target of 15%, the size of nuclear power to at least reach 75 million kilowatts, while the hydropower installed capacity will have reached 380 million kilowatts, of which 330 million planned for conventional hydropower, 050 million plan to build can plant. The use of other biomass should scale more than 2.4 million tons of coal.

River ice, and now has become more perfect and mature planning, preparations are being submitted to the State Council in accordance with the procedures for approval. According to preliminary estimates, the plan implemented in 2020 will greatly reduce the excessive dependence on coal demand, can reduce sulfur dioxide emissions that year about 780 million tons of carbon dioxide emissions by the year about 12 million tons. Planning period to increase accumulated direct investment of 500 billion yuan, an annual increase of output value of 1.5 trillion yuan.

Back in September last year, President Hu Jintao at the UN summit on climate change proposed for 2020 non-fossil energy accounts for a proportion of total energy consumption about 15%. In December, Premier Wen Jiabao climate change conference in Copenhagen announced to the world by 2020, China's carbon dioxide emissions per unit of GDP decreased 40-45% compared to 2005. Building low-carbon society, development of new energy is the trend, but also a long-term future of China's basic national policy, in order to achieve a solemn commitment to China's foreign, National Energy Board is organizing the units to "five" energy plan for the work, its emphasis will focus on the development of the proportion of non-fossil energy and carbon emission reduction to start two goals.

According to preliminary calculations, the planning period increased the cumulative direct investment of 500 billion yuan, an annual increase of output value of 1.5 trillion yuan, an increase of 15 million jobs in the community. So the next 10 years energy industry will enter a new stage of rapid development, room to grow quite broad, and likely the birth of a large number of new blue-chip, high-growth stocks in the future one of the main areas.

Problem: both "big step forward" and avoid "excess"

In policy and market the "double-sided optimistic", the new energy industry seems to deviate from the explosive growth in a predetermined orbit. Industrial development in China's history, "step forward" and "excess capacity" is always go hand in hand, how to balance the relationship between, it has been a problem.

Statistics show that currently there are 18 provinces and cities have been put forward to build a new energy base, or the new energy as a pillar industry to develop, this rush to develop not only a waste, it will also affect the orderly development of the entire industry. When the whole world for the layout of the new energy and renewable energy industry around the corner, puffed up with pride when there is a sound not be ignored: "No rules can not be into the surrounding area, the blind expansion of the momentum must be vigilant."

Now, the rapid development of China's new energy industry, individual industries and even a "blowout" of the momentum. Statistics show that China's PV industry annual growth rate of the past five years nearly 150% growth in wind power is doubled. As of 2008, China is the world's largest producer of solar photovoltaic cells, the fourth wind power country. But this "prosperity" hidden under there: some local governments and enterprises blindly launched a new energy projects, or duplicate construction industry chain, resulting in some of the industry has just started, had already appeared or blindly follow the trend of unbalanced development of the precursor.

China Investment Advisory Network issued a report, to wind power, for example, as of 2008, China's total installed wind power capacity of 12.2 million kilowatts, and total network capacity compared to 894 million kilowatts, which means that nearly 28% of at least wind power equipment has been built to be idle. This is reminiscent of recent years in China, including steel, cement, coal and other traditional industries to expand and adjust the capacity of the blind structure of the facts.

In fact, a simple high productivity is pretty harmless, but more serious problem is the production capacity over the remaining hidden in some production processes are often not high-tech, simple process repeated and so on, which means high-speed operation of the machine not only failed to produce more profits, but consumes a lot of production. If a bear new economic growth point of the industry, launched the beginning of the hidden from the low-level redundant construction and overcapacity in the shadow of the new industries to take off the way it is set back a huge regret.

China's National Energy Board of new and renewable energy Shi Lishan, deputy director of the wind power plant in Jiangsu Province recently research pointed out that China and other new wind power and solar energy in recent years, rapid development in production, but still the corresponding grid construction to be improved, from the rational allocation of production and use is still some distance.

In fact, many of the key components of new energy production technologies still rely on imports, and these techniques have been the United States, Germany, Japan and other countries a few companies a monopoly. For example, the absence of core technologies, domestic enterprises can only be in the lower reaches of the solar cell, battery components and other aspects of production. In China, the so-called polycrystalline silicon and other new energy industry, but it is still in the low-tech, low-level redundant construction phase, in the downstream industry chain.

Distribution: one-fifth of investment in the auto industry

Institute of brokerage analysts believe that additional 5 trillion of the huge investment in new energy industries, is expected to have at least 1 trillion will be allocated to the new energy vehicles, but this time in addition to the vehicle, the battery to power the core a very optimistic about the auto parts industry, a segment of industry.

"The battery is new energy automotive industry chain, the most important and most valuable part of an investment." Hongyuan Securities analyst Wang Jing said. Battery is the core of new energy vehicles, the most critical components, as predicted lithium-ion batteries will soon become a mainstream alternative to nickel-hydrogen batteries power batteries, lithium batteries power the new energy vehicles for demand-pull as the brightest body focus. Clearly, the lithium-ion battery, motor, electronic control and other related industrial chain of electric car companies will face even greater opportunities for development.

Zhang Xiaoyu, chairman of China Society of Automotive Engineers introduced, the current electric cars are the development of new energy vehicles subject, and key technologies of electric vehicles, including batteries, motors and electronic control of three parts, which is the most central parts of the battery. In these areas are under development in our country, not to the industrialization phase. Unfortunately, however, the current core component of our battery positive and battery separator, 80% are imported.

He said the battery's high import rate of the core components to the development of new energy vehicles in China has sounded the alarm. China is the world's most resource-rich countries of lithium, with the development of battery power resources. Happily, our country has begun to attach importance to the development of battery power, especially in battery-based technology investment and increasing common.

China FAW Technology Center director, said Li Jun, the Chinese government's investment in electric vehicles is very large, and very seriously. New energy vehicles or electric vehicles can not solve China's pollution problem locally, even if electricity is sent to the coal, not the low-carbon economy, but after all it is local, it can solve the pollution problem, can solve the problem of energy transport . But the future is not very large as an industrial leap, this also depends on our own for the automotive industry technology level of certainty.

Interpretation: "5 trillion" and "4000000000000" What is the difference

5 trillion! Is indeed an exciting figure, less than the financial crisis, "2009 economic stimulus package of 4 trillion" even more. Well, this 5 trillion of new energy industry planning in the end mean? And 4 trillion industry stimulus plan different?

The industry believes that this "5 trillion," and 2009 "4000000000000" is quite different. Market analysis, the "5 trillion," focuses on long-term effects of new energy investment, short-term stimulus to economic growth is far less effect in 2009, "4000000000000", so the stock market response is not so strong.

From 5 trillion of new energy investment planning time point of view, across from 2011 to 2020, span the time period of up to 10 years. Equally to the annual capital investment of far less intensity, "4 trillion." Meanwhile, the "5 trillion," a state for the new long-term energy sector development plan, not the immediate macroeconomic stimulus.

Dean of Economics, Fudan University, Professor Sun Lijian that China should seize the new round of global industrial restructuring opportunities, the initiative to a new industrial restructuring, including new energy, low-carbon economy, the concept of the industrial environment. In addition, China's foreign trade should be guided, for industrial upgrading. Exports, to encourage high value-added exports.

The point and purpose of the policy implementation is different from 4 trillion in 2009, is introduced in the international financial crisis, designed to rapidly stimulate the economic recovery has stabilized, inhibited macro-economic decline. The 5 trillion of new energy investment plan in the economic recovery trend has been set, enter the security macroeconomic growth, structural adjustment and development stage, are long-term economic structural adjustment range.

Laptop battery maintenance of the new law

Laptop battery maintenance of the new law

Words of today's notebook computers have become a fashion, more and more people to give up the desktop, select the books began. Not only in portability has a lot of advantages, make it a more integrated hardware footprint smaller. The most important reason is the use of rechargeable laptop battery is one of the advantages relative to the desktop, it can greatly facilitate a variety of environments the use of laptop computers. And with the level of battery technology advances, long battery life of notebook after another. Today, let's talk about that point on the laptop battery thing.

With the notebook with the passage of time, many of my friends was feeling battery aging, battery life shortened. In addition to buy a new battery, there is no way to repair the battery?

Study the fundamental reason is because the over-charging and over-discharge of lithium-ion batteries cause permanent damage to the positive and negative, which is the battery life issue. More importantly, if the charging process due to unexpected disruptions, its internal chemical reaction will occur complex changes, at this time are likely to affect battery life. To this end, the depth of discharge and charge is to protect the laptop battery a good solution.

Many brand name notebook with a dedicated discharge software, unfortunately if your notebook is not a dedicated discharge software, you can follow the steps below. First, disable the screen saver in Windows Power Management power scheme set to "always open", and the alarm tab will be "insufficient power warning" is set to 10%, the operation set to "no action." Then the "a serious power shortage alert," set to 3%, operating as "waiting", while the screen brightness set to maximum. Save all work before the data, and confirmed more than 80% battery, unplug the power and all external devices.

After discharge the notebook will automatically shut down, then the power plug for laptop charging, this process can be repeated 2 to 3 times. In fact, this approach aims to make continuous low current battery discharge, which discharge state in our daily use can not be achieved, the effect of discharge and those dedicated basically the same software.

If this time is no apparent effect, so essentially belonging to the battery can not be restored, this time to spare you should consider replacing the lithium-ion battery pack inside the core.

However, in order to make our "books" to better use: now the following way for everyone to know about drying out:

1. When no external power supply case, if the working conditions at the time slot being less than PCMCIA cards, remove the card first proposed to extend battery life.

(2) at room temperature (20-30 degrees) for optimum battery working temperature, the temperature is too high or too low, the operating environment will reduce battery time.

3 can provide a stable power supply in the environment using a laptop computer, remove the battery for extended battery life is not right by. On ASUS notebooks, when fully charged battery, the battery charging circuit will automatically shut down, so the phenomenon of overcharging does not occur.

4 is recommended to conduct a three-month average battery power correction action.

5 to minimize the number of battery. Battery charge and discharge directly to the life of each battery charge, battery on a step forward to retirement. Suggest you use an external power supply.

6 using an external power supply when the battery removed. Some users often several times a day the power plug, and the laptop with the battery, do more damage to the battery. Because each time access is equivalent to an external power supply battery charge time, battery life shortened by a natural.

7 after the exhaustion of battery charge and avoid charging time is too long. Regardless of your notebook to use nickel-metal hydride or lithium electricity, to power must be exhausted after the full (capacity less than 1%), which is the best way to avoid the memory effect. Lithium also have memory effect, but it is the memory effect than Ni-MH small number of Bale.

8. Peacetime Caution: When used in peacetime to prevent exposure to prevent damp to prevent the erosion of chemical liquids, avoid contact with the metal battery contacts, etc. happen.

AVIC force lithium battery industry

2011-09-13T15:31:00.001+08:00

AVIC force lithium battery industry

AVIC lithium big is brewing industry projects, expected 2020 sales of $ 50 billion. Listed companies through its integration into the flight (002190.SZ) lithium battery industry to achieve the first round of financing, the implementation of lithium in the aircraft industry is an important step industry. Integrated into the flight was from July 14 from the suspension.

July 18, "First Financial Daily" exclusive interview, the aircraft industry of non-aviation civilian Minister Yin Weining said: "The new energy industry, especially the lithium group was listed as an important industry. Integrated into the flight and fund-raising, investment in lithium ion battery is the first step. in accordance with the aircraft industry 'trillion' sales targets, by 2020, civilian sales to reach nearly 50 billion, of which lithium industry will achieve 50 billion yuan. "

July 6, integrated into the fly's announcement, the number of non-public offering to be no more than 106 million shares, non-public offering price of not less than 9.70 yuan / share. Non-public offering of fund-raising total to be not more than 1.02 billion capital increase to raise funds will be used in aircraft lithium battery (Luoyang) Limited ("CNAC Lithium") construction "lithium-ion battery project." Luoyang base of the project total investment of about $ 1.7 billion.

Future re-cast ten billion

The integration into the flight of the nine non-public offering of objects, including the aircraft industry's another listed company Hongdu Aviation (600316.SH), in charge of the domestic aviation industry's first equity fund in Tianjin Yufeng Investment Management Limited.

AVIC ambition of the new energy is far more than that. It is reported that, in addition to non-public offering financing, future plans in the aviation industry will invest 100 million to develop the lithium industry.

Yan Weining, said: "China's future development potential of lithium industry is huge and last year China's auto production and sales exceeded 13 million, is expected to 17 million this year, 2011 may reach 20 million. 3% to 5% according to the ratio of two During the year, sales of electric vehicles in China will reach one million or more. "

Recently, the State-led the establishment of the "central business electric car industry alliance" in the aircraft industry with the FAW Group and other companies with more than ten, included.

Made in the aircraft industry, the development of lithium power industry, implementing distribution strategy in the East and West, in Luoyang, Central Air lithium will be the core focus on the eastern Yangtze River Delta in East China and the west in the Chengdu-Chongqing layout; the south is in the Pearl River Delta layout; mainly in the northern part of the layout of the Northeast.

Lithium industrial strategy in the aviation industry, from the 2006 national launch of the "Eleventh Five-Year", "863" energy-saving and new energy vehicles of major projects. In 2007, after more than six months after the research and demonstration, select a lithium battery project, and the group in Luoyang, central China Air to Air Missile Research Institute for the restructuring.

Air lithium in the reorganization, the missile's civilian hospital mechanical and electrical companies such as CAMA, CAMA and control, CAMA Electronics, CAMA gas supply, etc., will focus on the development of lithium industry, and the formation of industrial clusters.

"Three-step" plan

The current global car manufacturers have the energy lithium batteries as a new car battery. International auto giants such as Ford, Chrysler, Toyota, Japan, Mitsubishi, South Korea's Hyundai, France, Courreges, Ventury and other domestic companies such as BYD, Geely, Chery, Lifan, also hybrid and pure electric vehicles, powered by lithium battery.

July 15, when in the interview with this reporter, in the aircraft industry partners GE Vice Chairman John Rice also said: "By 2015, the company will add $ 10 billion Ecomagination R & D projects, including the development of hybrid battery technology. "

Analysis of the industry, the automotive battery industry in China developed rapidly, production second only to Japan. As "863" key project of China's automotive lithium-ion battery project, most of the material to achieve a localization, the country has introduced a number of self-built and production lines. Related materials have more than one, have formed large-scale production.

"The current high cost of domestic manufacturers single battery life, battery management system, the battery level of group technology, both commercial and abroad there is a gap. The aircraft is currently in the leading position, and gradually form a lithium battery industry, the whole value chain and the whole chain. "Yan Weining said.

Air lithium raised in 2010, plans to invest 300 million yuan, construction Luoyang lithium-ion battery industrial base; 2013 total investment of 3.6 billion to build 1.2 billion Ah lithium-ion battery production capacity, a new energy companies; 2015 sales of more than billion, the formation of lithium-ion battery green energy industry cluster, as the world's lithium gold supplier.

Buddha enterprises invention pioneered technology battery recycling

Concern about contamination of used batteries, the battery can poison the whole body is turning waste into treasure? Recently, Foshan City, nickel and cobalt Bump Technology Co., independent research and development of battery recycling technology through the identification. Using this technique, capable of handling 1.8 billion in used batteries.

Many cells seem small, but because many of its constituent elements with toxicity, and if you throw water on soil and other environmental hazards is quite amazing. According to the test, a button battery 600,000 liters of water can be contaminated; a rot in the ground at the battery, make the 1.6 square meters of soil permanent loss of use value. Rotting garbage mixed with used batteries, after which the mercury, cadmium, lead, nickel and other heavy metals dissolved in the ground, will suffer serious water and soil pollution, thus affecting the ecological environment and human health.

According to reports, there are many manufacturers in the production of nickel-cobalt-manganese composite materials, but mostly from the mineral extraction or synthesis of a single metal products, etc., and directly to the recycling of waste batteries, the company is still the country's first Bump. The Bump company through the identification of the cycle technology to produce ternary composites (nickel-cobalt-manganese and lithium) and recycling technology to produce ternary precursors (nickel, cobalt and manganese hydroxides), is the used batteries as raw material directly to the "change "back to the battery materials.

By the Guangdong Provincial Light Industry Association, Yang, director of the experts group of big firms agreed that the two proprietary production techniques have reached domestic leading level, with obvious economic and social benefits worthy of promotion. By the company led the drafting of lithium nickel manganese cobalt and nickel cobalt manganese hydroxide two national standards have been developed.

Expert view: The new energy vehicles, "fully behind" vast

July 13, upstream of the new energy automotive battery performance of more active stocks. Analysts believe that the subsidies have been introduced specifically to support electric vehicles, battery electric vehicles is the core component of the market have a relatively high degree of concern is understandable, but the current production level of domestic battery and abroad, there is a sizeable gap.

China Automotive Information Centre, said network chairman Xu Jinquan, the battery industry chain including raw materials, materials, separator, electrolyte, management systems, not only the battery manufacturer, the whole industry chain will benefit from the development of new energy vehicles. In addition to batteries, motors, electronic control, also benefit from the development of new energy vehicles, but the battery is most easily understood by people, and thus most likely to become the object of financial speculation.

Despite the market's enthusiasm, China's new energy battery and the whole automotive industry chain, the status quo is not optimistic. China Association of Automobile and General Director Young that, in the new energy vehicles in China and the world advanced level there is "more comprehensive" gap. "Chinese Rare Earth exports, but China is not a car company to do well with the permanent magnet material; electric car motor efficiency is very high, with Chinese enterprises with ultra-thin silicon steel motors are usually do not; China has a lithium resources, but also need to import a high level of lithium iron phosphate powder; China's production of batteries can only be used for mobile phone firms, compared with the three high-end phones do not divide. "

Xu Jinquan believes that China's new energy automotive industry chain is facing bigger challenges, but due to a large market, as long as government support in the future should be able to develop, but there are some serious domestic companies do.

Than the traditional power grid, smart grid carries a huge market space. Smart grid is technology-intensive, capital-intensive collection, will lead the new energy, information, sensors and other traditional industries, innovation and development, with strong technical and economic drive of radiation.

State Grid Corporation of proposed analysis and forecasting: From 2011 to 2020, the national power grid intelligent building investment will be over 400 billion yuan, can lead the whole society-related industries, output 1.5 trillion yuan, of which the core technology industry, including 300 billion yuan of new electrical equipment . Around the development of intermittent power transformer protection monitoring device, only the "five" period, China should build national smart grid substations around 6000 or so, "13 during" the scale to reach 7000. Which has a very huge market space.

Family life-changing intelligent terminal

How wonderful smart grid in the end? Take smart home, it's broadband communications over power lines or optical fiber communication technology, in the family configuration intelligent terminals, users interact with the grid, and through wireless communication technology to further extend to the water meter, electricity meters, gas meters, etc. antennae, Collecting data. It can also be achieved through the intelligent socket air conditioning, electric rice cookers and other electrical data acquisition and control; the main network via wireless technology to create sets of emergency relief, gas leak detectors in one home applications. , People go out, if the dog clawed the refrigerator door, the phone will soon receive a text message. If the thief touch the house, not to mention.

"Replace the battery Plan" in exchange for blue sky

Make such a comparison: about 100 km fuel car fuel consumption 11 liters of gasoline by 6.6 yuan / liter price, fuel costs about 70 yuan; domestic travel 100 kilometers of pure electric vehicle power consumption of about 15 degrees, to price 0.52 yuan / degree, as long as fuel costs 7.5 yuan. Thus, the cost of electric vehicles using fuel car is probably 1 / 10.

National Grid is preparing the implementation of brewing in Beijing "for the battery program," to transform the taxi. Taxi enter power plants, 5 minutes to ensure a good battery can be changed. Implementation of this model, the taxi drivers can add a month income of 1000-2000 yuan, while energy conservation will help bring "blue sky."

Look at the future of electric cars from the Santana

Electric vehicle purchase price is high, because the market due to the small quantities cause. However, lower prices of electric vehicles is a trend, just as car plant in Shanghai's Santana the same. 20 years ago, we saw a Santana in Yangzhou city, will be shuffled around and how much envy. Santana was a price in the 200,000 to 300,000 yuan or so. Until the scale of production, the price of a Santana is now less than 10 yuan. If the electric vehicle mileage continued problems with the battery when the continuous development and development can be effectively addressed, then it cut prices to market a large area not far away.

Take the battery to make money is not a dream future

Yi-Min Wang in the report: the future of electric vehicle batteries become a smart grid energy storage device. Economic-minded good people, to low power in the middle of the night the price for the car battery. Once peak, he can store electrical longer sold. The future, take the battery to make money, not a dream.

Compared in terms of conventional fuel vehicles, electric vehicles energy management system complexity. In other words, when the electric vehicle charging, when the discharge, must have energy management intervention. Therefore, the charge pile, charging stations, and it is an extension of the industry, have a very broad market.

Yingli sponsorship behind the World Cup: foreign business competition

July 1, Baoding. XiXi the rain did not affect the "China's Yingli" and "hot."

"Yingli, not on the World Cup?" In the way to Yingli Group, Baoding, a brother of the China Economic Times correspondent said.

On the road, the reporter did not find much British interest in the advertising, it would seem that the British interest has been low-key image. Today, with the intense World Cup, the world's first renewable energy World Cup sponsor, sponsor China's first World Cup title had already been Yingli famous worldwide.

Yingli "low" to "high profile" behind the intensified battle for the world PV market.

Local enterprises to accelerate global expansion

Leading to Yingli Group Chief Strategy Officer Ma-lu the office of the corridor, "China's Yingli" on display in the World Cup draw everywhere.

In general, FIFA does not allow sponsors appear in advertising design country. But Lee insisted on using English, "China's Yingli" word for the World Cup to add Chinese elements. Yingli sponsor the World Cup's success, another point is the concept of green energy and green football consistency.

"The high cost product is our goal from this perspective, China's Yingli in the global industry is now as much as any business." Ma-lu said.

However, speculation that British interest in the World Cup gamble, the high cost of $ 80 million, $ 60 million, 500 million yuan and other variety of claims.

"The figure is certainly not as they say, but I can tell you, is certainly value for money. Yingli into the World Cup is not on impulse, the effect has been greatly exceeded our expectations." Ma-lu said.

Data show that the financial crisis, more and more countries to exert new energy. PV market is only seven or eight countries from the initial expansion to three dozen countries. Structure from the PV market in the world's largest solar market in Germany, about 50% of the PV market is a large ground-power projects, 50% of residents of the roof project.

"Football is often developed areas in areas of photovoltaic demand in Europe as the single most residents of households, far away from the housing, the future residents or smaller-scale enterprise applications will be relatively large potential for solar energy The future of solar PV Group Overseas parts BTOC must rapidly expand market share. "Ma-lu said, awareness promotion, Yingli Green Energy will help to promote to the world.

In fact, the financial crisis, the expansion of British interests in the world is gradually accelerated.

Since the NYSE board three years ago after landing the United States last year, British interest in planning for renewable energy projects in Hainan, in addition to headquarters to become the largest outside investment. This expansion not only from Europe closer, and can radiate Southeast Asia. April 20, by the British interests of their own design and construction of South Africa's first grid-connected PV systems engineering and network successfully, with the sponsorship of the World Cup effect, the British interest in Africa has begun to open up the market.

"Made in China" products in the international competitiveness of the market is still mainly rely on low prices, show that the Chinese enterprises in the international market brand defects. "China's Yingli" popular night the other side, the PV market in China products is not only cost-effective, brand strength is also starting to show.

China's manufacturing sector are present throughout the problem: too few global brands in high-tech leader in low level in the world market share and core technology is not high.

In Ma-lu view, among all industries in China, and the world to the simultaneous development of high-tech industries, mainly photovoltaic industry. "China's manufacturing capacity is now roughly equivalent to 40% of the world should seize the opportunity to maintain the high technology sector in the photovoltaic industry with the world, until beyond the developed countries.

Foreign glimpse covet Chinese market

Chinese companies in the world, the forefront of solar cell suppliers. However, the China Renewable Energy Society, vice president of Mengxian Gan told the reporter, due to the relatively large gap between domestic and foreign prices, coupled with domestic policies in place, 98% of China's solar photovoltaic cells are exported to foreign countries.

Upside down in the same industries and markets, with China's increasing emphasis on renewable energy, solar energy products, demand is facing growth opportunities. Foreign-funded enterprises to accelerate the pace of opening up China's solar market.

According to The Wall Street Journal reported that the U.S. company Applied Materials, an agreement signed in May, will ENN Solar Energy Co., Ltd China sell thin-film solar cell production equipment, production out of the battery will be used for important state-owned alternative energy projects, the developers China Energy Conservation Environmental Protection Group in Inner Mongolia will build a new large-scale solar farms.

The reporter was also informed that in early July by the Australian Centre for Renewable Energy on behalf of six members of the Australian renewable energy company executives and industry leaders delegation will visit China. Among them the solar energy business.

However, domestic enterprises have not taken lightly and sit. Start the application in the domestic PV market, China's second batch of photovoltaic power generation invitation to tender was launched on 23 June.

Benefit from a British newspaper correspondent was informed by insiders, the British interest to participate in the tender. However, the people do not want to disclose too many details.

March 2009, the first photovoltaic power generation 10 MW project bidding Dunhuang national tender, SDIC and Yingli Power Holding a joint tender body once 0.69 yuan / kWh, low price sensation in the industry.

"PV price is not unattainable. Photovoltaic want to open markets in China, the first significant reduction in costs, or it will not open in China." Ma-lu said.

In Ma-lu view, reduce the cost of photovoltaic products, there are many factors. For example, the efficiency of crystalline silicon solar cells are constantly improving; localization of the equipment continues to accelerate; industrial chain in an increasingly balanced, photovoltaic inverter and control systems such as the development of promising.

He cites the construction of 1 kilowatt thermal power needs of 4,000 yuan, saving one kilowatt of electricity needs of 2,000 yuan. If economic development and the need to increase 100 million kilowatts thermal power, require a total investment 400 billion yuan. If half of that 50 million kilowatts for the construction of thermal power plants to solve, while the other half with saving way to resolve. In fact only need to invest 300 billion yuan, you can save up to 100 billion yuan. PV battery life is 25 years, this 100 billion yuan for the construction of solar power plants, will create huge energy reserves.

"Improving solar cell subsidiary other than the life of the product and value, and product availability and quality, the cost of commercial solar energy will be dropped significantly as technology advances and the introduction of new materials, the cost of photovoltaic power generation will be more low awareness of energy saving with the people, improvement of living standards and the constant introduction of new energy policy, etc., will soon move toward solar power thousands of households. "Yingli Solar Applied Technology Research Institute Y. Wang told reporters on the China Economic Times.

To stabilize the market price of polysilicon thin-film temperature back

2011-09-02T11:36:00.000+08:00

To stabilize the market price of polysilicon thin-film temperature back

Experienced in 2009 after a dismal situation, the current thin-film solar market seems back to temperature signs. June 9, 2010 -11 days held in Munich, Germany, Intersolar Europe Exhibition), the thin film solar manufacturers sales than expected.

Comments: Investment Advisor in the new energy industry, said chief researcher Jiang Qian pointed out that as the world's largest solar exhibition professional, Intersolar on a variety of products, market trends, which can be seen as the industry benchmark. Since late 2008, the financial crisis raging, worldwide polysilicon prices blew out, and the resulting crystalline silicon cells, the component prices drop, but the cost advantage of thin-film battery in the past has ceased to exist, the market also extremely bleak. And this effect is directly transmitted to the field of thin film devices.

The equipment manufacturer Oerlikon thin film battery, for example, first quarter 2009 sales of 51 million Swiss francs Oerlikon, with the same period in 2008, a decline of up to 32%. The impact so far has not fully subsided, the first quarter of this year's sales continued to decline to 39 million Swiss francs (about $ 33,988,500), down 24%.

Jiang Qian pointed out that although the Oerlikon Solar is a business operation data, but as the world's leading thin film equipment manufacturer, Oerlikon sales declined year by year, also reflects the current investment in thin-film technology has no 2008 years before the heat, which is an important industry back to a rational expression. However, from another perspective, although investment in thin-film batteries, and not before 2008, the heat, but the situation has stabilized the overall price of polysilicon under the film market warmed not hard to understand, and this is bound to have will once again push back the investment in thin-film batteries.

From the general point of view, since 2006, the development of thin-film battery has been an upward trend. Investment Advisor in the latest release of "2010-2015 China thin film solar cell industry, investment analysis and forecast report" shows that the 2007 global thin film solar cell production reached 400MW, 181MW in 2006 compared with a substantial increase of 120%; 2008 the world's film solar cell production reached 892MW, an increase of 123%. In addition, the CIGS thin film battery, for example, in 2008 global production of CIGS cells around the 40MW in 2009, is further capacity more than 660MW, about the actual production reached 180MW.

Although so far, the conversion efficiency of polycrystalline silicon solar cells are still much higher than the various types of thin-film solar cells, but its relatively high cost is obvious. The CIGS thin film solar cells to flourish, it is the industry in cost and efficiency for both guaranteed a try. Therefore, we can say that although it can not determine the future of thin-film solar cells will be able to replace the polysilicon solar cell market position, but the thin-film battery with competitors popping up, and the rapid development of the whole industry forward at least one of the major performance.

Mitsubishi Motors: The production information with the Toshiba Battery Exchange

2, Mitsubishi Motors of Japan said it would exchange with the Toshiba batteries used in electric vehicle production information, but did not decide whether the application in production of batteries produced by Toshiba.

NEW YORK, July 2 reported that Japan's Mitsubishi Motors Corporation (Mitsubishi Motors Corp.) 2 said Monday that with the Toshiba Corporation (Toshiba Corp.) Exchange used in the production of battery electric vehicle information.

However, a Mitsubishi Motors spokesman said, Toshiba is the Mitsubishi Corporation, one of the exchange of such information, but did not determine whether the battery will be used in Toshiba Mitsubishi electric car production.

Jinan will invest 1 610 new energy vehicles, electric vehicles, how far

2011-08-30T16:29:00.000+08:00

Jinan will invest 1 610 new energy vehicles, electric vehicles, how far

The province's first large-scale electric vehicle charging station recently completed in Linyi, on the promotion and use of electric vehicles have become the focus of attention. Jinan City in accordance with the plan, by 2012 the city will run a variety of new energy vehicles 1610. At present China's auto market in addition to buses, the only electric vehicle in the sale of a class of hybrid and pure electric vehicles currently on the market yet, basically stuck in the concept stage, many manufacturers are stepping up development of pure electric vehicles, electric car away from our lives is getting closer.

No price advantage of electric cars

Orders from the current distribution of electric vehicles, government, and public transportation systems are large purchases of electric vehicles, and buses are mostly behind the government-led, therefore, the Government's promotion of electric vehicles to become a major force behind the development. Can people, they will still be considered an account: electric vehicles and ordinary vehicles compared to what is cheaper?

The transition from gasoline vehicles to hybrids and then transition to a pure electric car is a trend, because the conditions are not yet complete in supporting the case of hybrid is a better alternative, and perhaps this alternative approach will continue for a long time, because the hybrid can be used in large displacement models, these models can also be long-term use. But a price of hybrid vehicles more than 10 million yuan, while imports of hybrid vehicles more expensive.

Pure electric cars of different price will vary according to performance. BYD E6 is the first introduction of electric cars, is expected to ship 30 million pre-sale price. Linyi Yi-up electric car production company the person in charge, they developed a configuration with lower electric car has not yet formally put into production, the estimated price of 40,000 yuan. According to the Ministry of Finance and other four ministries jointly issued a new energy subsidy programs, plug-in hybrid maximum subsidy per 5 million, the highest electric vehicles per 60,000 yuan subsidy. For those who predict lower prices for electric vehicles may only make up at least less than 1 million.

This means, buy a configuration relatively low electric car takes about 30,000 yuan, the price and a lower fuel vehicle similar configuration. If a fuel for private cars per day travel 20 kilometers count, driving about 7000 km a year, to 100 km fuel consumption volume of 8 liters per liter of oil 6.3 yuan, 3528 yuan a year to spend the oil money. The use of electric vehicles, fuel vehicles cost about 1 / 4, driving the same distance to spend 900 yuan per year, this year can save 2,600 yuan. However, this electric car every two years to replace a battery, costs about 5,000 yuan, the annual cell loss is about $ 2500, this means fuel vehicles compared with almost no price advantage. Configuration of high electric car batteries cost more.

Experts said that with the technological development of electric vehicles and battery cost has a significant price cut.

Need to improve the conditions of use of electric vehicles

Electric vehicle batteries is to solve the first problem, mobile phones commonly used nickel-metal hydride batteries and lithium batteries used in electric vehicles, but the small capacity nickel-metal hydride battery, lithium-ion battery costs are too high; BYD F3e currently used in electric vehicles iron on cell battery, this battery safe, cheap, high capacity, the disadvantage is the weight is too large. Either high prices, small electricity either, had to weigh the public to buy electric cars weigh.

Where the charge is that many people consider the real problem. Many cars parked in underground parking or temporary parking area, where there is no accompanying charging plug. If you want to stop when the charge depends on the use of supporting construction. According to the plan, the city will build five electric vehicle charging station and charge pile, but also in the process of building trouble. Jinan power company concerned parties, with their parks, scenic areas, car parks and other units in contact, project construction in these areas charging pile, basically do not take up land, win-win thing. However, after who will manage the construction, who is a maintenance problem, the investor and operator of awareness of inconsistencies.

Charging time will also affect the electric vehicle. China built some places charging station, charging pile using high-voltage power fast charge mode, charge 10-15 minutes for the electric vehicle 150 km, but this fast way of damage to the battery charge is relatively large. If the charging station with fast charge, fully charged need 1.5-2 hours, at home, will have to charge about 5 hours. This use of people, charging time seems a bit too long.

Five years or so electric cars to enter millions of households

Chinese electric vehicle control technology experts, Beijing University of Technology I too believe that up to now, no one can be like a new energy technology can also lead to the world as governments, businesses and consumers attention. China's government is boosting new energy to spare no effort. March 20, 2009, the State Council issued the "automobile industry restructuring and revitalization plan", which specifically said the development goals, by 2011, form a 500,000 electric, plug-in hybrid and common type of hybrid and other new energy vehicles capacity, the new energy vehicle sales accounting for about 5% of total passenger car sales. Now, many provinces and cities to invest heavily in R & D of new energy vehicles.

New energy vehicles far away from us it? Up too much more than that, during his visit last year, Obama issued a joint communique, the energy is an important element, which said the United States agreed in the next five years, US-China Clean Energy Research Center to spend at least $ 150 million, while U.S. electric car startup initiative, the two countries in the next few years, several million electric cars in use. Although many conditions are not available now, but with the technological development and progress, a lot of negative factors will be improved. I predict that up too, perhaps within the next five years or so, electric vehicles will be households.

China Solar shine in the World Cup

Associated Press June 25 article, the original title: Chinese solar company in the World Cup, "shining," the Chinese team failed to enter the World Cup, but the country still has to show his face in South Africa. An ambitious Chinese solar company has hit its advertising within the arena in South Africa all the hope in the world to promote their brands.

China's Yingli Green Energy signed a sponsorship agreement, the current total of 64 soccer match on the venue we will be able to see this on the electronic billboard company logo. The vice president said, "The World Cup is a very good platform, but also all the potential in the global market rapidly increase our brand awareness."

Currently, FIFA's sponsors are mostly dominated by consumer goods manufacturers, such as McDonald's and Budweiser beer, Yingli is the first sponsor of renewable energy. Analysts said that, it sounds like solar panels and football is a pair of very unusual combination, but the sponsors will help to shape the brand credibility, and to meet investor demand. Sports marketing firm Helios Asia-Pacific director Stuart James said, "All Chinese people and the world as people now know that only companies to survive."

In recent years, Chinese companies have spent hundreds of millions of dollars used to finance international sports events, full of ambition to expand their overseas markets. More than 20 companies cooperate with Beijing Olympic Games, including the Lenovo computers.

More expensive gallium arsenide thin film solar cells in research and development

University of Illinois researchers are on the silicon by a "growth" multi-layer materials, to develop lower-cost thin-film gallium arsenide solar cells.

Gallium arsenide is a semiconductor compound, can be used to produce solar cells, and energy conversion efficiency than conventional silicon-based solar cells more potential.

Currently, researchers have to make conversion efficiency of 25% to 30%. However, the high manufacturing cost is still the great obstacle to technology commercialization.

The School of Materials Science and Engineering Department of Chemistry, professor JohnRogers, and another professor XiulingLi, are looking for lower-cost technology to produce gallium arsenide film. At the same time, they also hope to find a common way to make the production of film for a variety of devices.

Production of gallium arsenide solar cells is usually in a small piece of silicon compounds on the deposition until the thin layer formed on the surface. The school's researchers are changing the way the layers of silicon deposited on the surface of gallium arsenide. This structure, the thin layer of gallium arsenide and aluminum arsenide are arranged alternately, looks like Americans eat the same school.

"Using this method, we can use faster and less cost, to get more product." Rogers said Professor, "Although we produce only thin, but the total point of view, we produce material much more. "

"If a thin layer of growth can be 10, it means to be the 10 only a thin layer of silicon," Electrical and Computer Engineering, Professor Li said. "If you took 10 times the growth response, then the reaction process of installation and removal of silicon, and the subsequent heating and cooling, need a lot of time if the machine, material preparation, time and personnel factors taken into account, our method can greatly reduce production costs. "

The study group in the journal Nature published a paper to clarify the process for three devices - light sensors, high-speed transistors and solar cells. They will also be made of this material compared with other materials.

The paper's authors, two are Semprius's scientists. The company is located in North Carolina, USA, is an emerging enterprise, the goal is to use the technical study group to produce solar cells.

The subject of the study group funded by the U.S. Department of Energy and U.S. National Science Foundation.

Stones from other hills: the U.S. and Japan to support the new energy vehicles

U.S. car industry, new energy subsidies mainly taken the approach to tax credits, subsidies that meet the criteria for sales of 60,000 hybrids for the line, total sales reached 30,000, consumers enjoy a 50% tax break; cumulative sales of more than 45,000 consumers to enjoy a 25% tax credit; total sales over 60,000, the buyers do not enjoy tax benefits.

The U.S. government believes that new car prices, energy sales of more than 60,000 vehicles, its basically achieved in this area, industry, the need for government subsidies is not clear. This system is designed to the limited use of the funds really want to subsidize development of new energy vehicles industry is committed to the enterprise body.

In the United States, consumers purchase less than 30,000 of the total sales of hybrids can not enjoy tax breaks, which is part of the business in order to prevent the production of new energy vehicles in the name of the product is not mass production wanted to get subsidies qualifications.

Meanwhile, the U.S. government in most states on the basis of federal subsidies to buy electric cars for private provision of additional financial assistance, such as in California, a light electric vehicles can get up to $ 5,000 subsidy.

On the other hand, the Japanese government, including individual consumers to purchase environmentally friendly hybrid vehicles, including the reduction of vehicle purchase tax and weight tax. Such as the price of 200 million yen, focusing on one ton truck to 1.5-ton hybrid vehicle purchase tax discount of up to 10 million yen, the weight of the car tax can be reduced or 56,700 yen. With the type of the car increases, the amount of the subsidies enjoyed by consumers will also increase.

Potatoes can also charge the battery Israeli scientists to develop potato

In many underdeveloped areas, the charge is a luxury behavior. Is there any way to simply providing power it? Israeli scientists think a ism: The potato generation.

Simply put, the potatoes cut into the box tied up, then insert a special zinc and positive and negative electrodes made of copper, the battery is complete. The researchers said that the use of potatoes, boiled potatoes compared to the simple, energy efficiency can be increased by 10 times. Potato battery life ranging from several days to several weeks, according to the actual situation.

Although the potato battery charge capacity, and we can not be used on a lithium-ion battery, but the lack of power generation facilities in place, this technology is equivalent to a readily available source of electricity. Israeli scientists said it would provide the technology free of charge to any interested developing countries. By the way, said this 100% environmentally friendly battery technology, but oh.

Hangzhou steady increase in the quality of the battery

In the new energy industry, the battery as an energy carrier to occupy an important position, which has a lead-acid batteries because of economy, large-capacity, high-power discharge, the use of security advantages in the chemical supply is always dominant, has accounted for 75% of the domestic battery market (power number).

Inspection and Quarantine Bureau, Hangzhou focus on inspection and supervision with daily work to push the lead-acid battery business, "quality improvement": a clear business is the quality of the main, the firm is responsible for quality, directly to the product quality and safety, regulatory agencies responsible for overseeing the quality of business conduct; strict supervision of the company's error will not be tolerated; warm service, the reasonable demands of business quick response, as soon as possible; check prices interact to enhance communication in the work-oriented and business communication, especially on industry trends, laws and regulations technical standards of the situation.

Check prices in the joint efforts of both sides, in Hangzhou, a decrease in the number of battery companies in recent years, increased competitiveness, product quality increased steadily, growing influence of industry, including Zhejiang Narada was listed on GEM in 2010, Hangzhou sea for a long time batteries in the A-share listing plan. Hangzhou battery companies have leading position in the industry, is to a higher goal.

Electric vehicle charging stations to carry out the pilot concept surfaced

2011-08-19T16:35:00.000+08:00

Electric vehicle charging stations to carry out the pilot concept surfaced

Ministry of Finance, Ministry of Science, the Ministry of Development and Reform Commission four ministries jointly issued a formal notice to carry out the private purchase of new vehicles to subsidize pilot energy, electricity in the new energy automotive industry chain, the most critical links and undoubtedly the most obvious beneficiaries of the charging station and charge pile construction.

Five pilot cities to urge the charging station

Just look at every side of the road in major cities in less than 5 kilometers to build some gas stations, charging stations will be able to fully understand the importance of the pile with the charge. Industry veteran, said local governments attach great importance to the charging station, charging pile construction, especially in this pilot in Shanghai, Shenzhen, Changchun, Hangzhou, Hefei, these five cities, investors can more clearly see that the local government vigorously charging station, charging the determination of pile construction.

Shenzhen and Shanghai's largest and relatively fast action. Shenzhen from June 1 to officially take effect, "Shenzhen-saving and new energy vehicle demonstration pilot plan", in addition to individuals, community groups and businesses to purchase new energy vehicles in the central financial subsidies granted on the basis of subsidies for supporting infrastructure is also subsidized.

Meanwhile, Shenzhen has also promulgated the "Shenzhen electric vehicle charging system specification", indicates the next two years in the residential parking lots and large shopping malls or high-end hotel car park build a new energy vehicle charging station. Total plans to build bus rapid charging stations of the 25 slow, slow charging official vehicle pile 2500, public fast-charging stations 200, public Slow charge pile 10000!

According to the Shanghai media reported that local government is actively considering the development of related measures, after the formation of the draft has been included to give the consumer prices of less than 20% of the one-time subsidy-free by the license auction process directly on the card registration, etc. . The latest development is the Economic and Information Technology Commission of Shanghai, said Shanghai will invest in the charging station and other equipment for 20% of the subsidy, the future will complete charge pile of nearly 400 construction projects.

The other three pilot cities in the footsteps of this area is not too slow. Changchun, the 4 charging stations will be built next year, 300 charge pile. First electric vehicle charging station located in high-tech zone, the end of June is expected to put into use.

Hefei is the national power grid construction, Anhui province-wide this year, will build five electric car charging stations and 300 charging pile, which was built in Hefei, 4 and 80 charging stations charging pile, in addition, will In Hefei build electric car pilot for pool station.

Hangzhou will build a large scale this year, charging stations, five small and medium sized charging station, 50-100 battery replacement service outlets, 130 charge pile. Hangzhou Electric Power Bureau Deputy Director in charge of the letter, said Cai, Hangzhou is exploring vehicle charging network construction mode. Advance the process of charging facilities, need to overcome the problem is the practical solution to Hangzhou car charging network distribution.

Thus, the charging station and charging columns build electric car industry in the new chain of energy services is very important position in national policy and local government together with support from the charging station will be smooth and fast start performance of listed companies such will also be a corresponding increase.

Charge will be divided three ways

Charging station according to the function can be divided into four modules, power distribution system, charging system, battery scheduling system, charging station monitoring system. Charging station needs a complete power distribution room, the central control room, charging zone, replace the battery area, and battery maintenance between the five parts. Distribution room for the charging station to provide the necessary power, not only to the charger to provide power, but also to meet the lighting and control equipment demand, a change in distribution within the building all the equipment, power distribution monitoring system, control and compensation-related equipment. Central control room for monitoring the operation of the charging stations, and complete management of the report printing. Complete charging of main battery charging function. Replace the battery area is the place the vehicle replacement battery, battery replacement required with equipment, construction should also be used to store spare batteries battery storage rooms. Battery re-equipped group, battery balancing, battery actual capacity testing, battery failure and other emergency work to maintain the battery between.

Charging station to recharge vehicles are generally divided into three ways. One is the ordinary charge, the so-called conventional charge or slow charge, the charging mode, the exchange is now plug in the car, you need 5-8 hours or 2-6 hours, this way more for the exchange of charging, 220V or 380V AC external power supply provided to the electric vehicle car charger, car charger to power by the battery charging. Generally small electric vehicles, plug-in available hybrid electric vehicles (pluginhybridelectricvehicle, PHEV) use more of this approach; The second is the rapid charging, the charging current to be larger, which requires the construction of fast charging stations, it does not require the battery is fully charged, only to meet the needs of you can continue driving, and this charge mode, in 20 minutes to 30 minutes time, only to charge the battery 50-80%, this way more than DC mode, DC charger directly to the ground to give the car power output battery charging, charging electric vehicles and related only to provide communication interfaces. Ground charger general power, output current, voltage range. Some of the ground fast charger also has the charging function; third is battery replacement.

Charging station is expected to be able to recover the 6-year

Charging station costs are divided into three parts: infrastructure costs, the cost of distribution facilities, operational costs. Charging station infrastructure costs from the charger, battery maintenance equipment, charging station monitoring and security surveillance equipment, land acquisition costs.

Now many stations are charging the provincial network construction companies and local government combined, are a lot of land allotted by the Government, land acquisition costs low, in the charging station infrastructure costs of judgments, if the land acquisition cost is 0.

Charging station infrastructure cost and configuration of the number of charger has a direct relationship, assuming there are 10 charging station charger, charger, battery maintenance equipment, charging station monitoring and security surveillance equipment cost of 200 million, 20 million, 20 million, the infrastructure cost of $ 2.4 million.

Distribution costs are relatively fixed charging stations, charging stations and distribution facilities generally include 2 transformers, 1 power distribution cabinet, 1 km 0.4KV cable, 2 km 10KV cable capacity 700KVA more active filter device, charging station distribution costs 192 million.

Charging station operating costs, including staff costs, fees and other station equipment consumed a total of 21 million distribution facility maintenance cost is generally about 3% of distribution costs, about 6 per million.

Cost recovery charging station and battery life actually has a lot of cost recovery charging stations and battery life to do a sensitivity analysis, when the battery life per hour 70KVA, the charging station infrastructure cost recovery period is 6.53 years, the basis of charging stations and distribution facilities to implement recovery period is 11.76 years; when the battery life up half an hour 70KVA, the charging station infrastructure cost recovery period is 3.27 years, the basis of charging stations and distribution facilities to implement recovery period is 5.88 years ; When the battery life to 15 minutes 70KVA, the charging station infrastructure cost recovery period is 1.63 years, the basis of charging stations and distribution facilities to implement recovery period is 2.94 years.

Overall, a single charging station infrastructure and distribution facilities is not a big investment, if the battery life can reach more than half an hour 70KVA, charging station can be controlled in the cost recovery period is 6 years or less. A single charging station infrastructure and distribution facilities investment at 430 million, the first phase of construction 75 charging stations with a total investment of about $ 300 million burden on the national grid is not. Cost recovery period from the charging station, when a half-hour battery life to 70KVA, the charging station infrastructure cost recovery period is 3.27 years, the basis of charging stations and distribution facilities to implement recovery period is 5.88 years, with the ability to enhance battery life , charging stations will reduce the cost recovery period.

National Grid invested heavily in the charging station

When the charging station large-scale construction, the charging station's main function is to achieve the fast charge, slow charge of the functions implemented by the charge pile. Taking into account the area of charging stations, charging stations should be configured ordinary 10 charger.

According to the national grid planning, the first stage of charging station master total investment will reach 300 million yuan, the second phase of 14 billion yuan in the third phase of 18 billion to the charging station master in 2020 the total investment will reach 32 billion yuan . Charging station master in charge, power monitoring systems, active filtering devices in 2010 will reach 1.5 billion yuan investment, 20 million yuan, 63 million yuan, the second phase of the annual average investment size will rapidly grow to 1.44 billion yuan , 1.6 million, 672 million yuan.

2020, a total investment of 12.5 billion yuan charge pile. 2010 charging pile investment 160 million yuan ,2011-2015 charging pile investment 4.5 billion yuan, an annual investment of 900 million yuan, is the first stage investment of 5 times the average.

7 companies benefit from the charging station

Charging station and charge pile construction process need to use many devices, such as chargers, power monitoring systems, active filtering device, charging pile, transformers, power distribution cabinets, cable, etc. Charger, power monitoring systems, active filtering device, charging station charging pile is used in the process of building up and relatively unique electrical equipment. Charger and charge pile equipment suppliers NARI, XJ Electric, Siyuan Electric, Auto Motion, Active Power Filter equipment suppliers RXPE, Siyuan Electric, Senyuan electrical, power monitoring systems equipment suppliers NARI, XJ Electric, National Power South.

On the whole, companies benefit from the charging station construction in the order of: NARI, XJ Electric, Hidenobu shares Senyuan Electrical, Auto Motion, Siyuan Electric, National Power South.

New energy standards for passenger cars and other urgent introduction of battery recycling

2011-08-17T11:42:00.000+08:00

New energy standards for passenger cars and other urgent introduction of battery recycling

In the past 2009 years, and medium-sized passenger car market slump. According to China Association of Automobile Manufacturers statistics, the annual and medium-sized passenger declines. However, in such a depressed market conditions, the Automobile Association's statistics show that more significant growth in alternative fuel buses, an increase of 27.27%, and these include a new energy bus, that is pure electric passenger vehicles and hybrid buses.

In the new energy vehicles in China has promulgated policies to encourage consumption and increase the intensity of the situation, in 2009, new energy bus rapid pace of industrialization process accelerated. Data showed a pure electric passenger car market in 2009 amounted to maintain over a hundred vehicles, hybrid electric bus fleet has reached 1000. Experts predict that by the policy of encouraging, the data will appear in this year's surge. "There will be 7 this year to 8 cities in large-scale demonstration projects to promote new energy bus." Electric vehicles, National Engineering Laboratory Electronics Department of the Rending Li told reporters learned.

By 2011, China to electric vehicles, hybrids, hydrogen fuel cell vehicles of new energy vehicles will reach 50 million units; through "10 City, 1000" policy, there will be million new passenger cars onto the city streets of Energy . Thus, a major issue for environmental protection in the industry will put in front: Currently, hybrid electric and pure electric vehicle batteries including lithium iron phosphate, lithium manganese oxide and other types of lithium batteries with the electrolyte is organic matter which, once released to the environment will cause harm. The new energy battery scrap bus no national standard, with new energy passenger car ownership increases, the disposal of used batteries urgent need caused by the industry's attention.

Recycling used batteries cause pollution standards is empty

Battery electric vehicles is a key component. Senior Product Engineering, Nanjing Iveco Paul Han Dong, said in an interview with reporters, lithium-ion battery energy storage per unit weight of high lithium resources are abundant and the prices are not expensive, so now the new energy bus commonly used lithium iron phosphate and manganese lithium batteries. He said that despite the long development lead-acid battery has matured, and was once widely used in electric buses, but its capacity is low, bulky, heavy pollution to the environment of lead-acid shortcomings, bus companies have been gradually abandoned.

According to the National Engineering Laboratory Electric Vehicle Electrical and Electronic Department of the Rending Li School description: "In accordance with state regulations, the number of rechargeable lithium iron phosphate should not be less than 1500, while the rechargeable lithium manganese oxide should not be less than 500 times integrated unit storage electric energy, number of charge cycles, a number of indicators such as cost, are superior to lithium iron phosphate lithium manganese batteries. "

Not long ago, the reports of scrap batteries pollute the environment seen in the newspapers. One report said a small button battery can be about 60 million liters of water pollution, water consumption is equivalent to a person's life; a 1 battery rot in the ground, make the loss of around 1 square meter of agricultural land value in use. This can not help but think, generally installed in the electric bus on the lithium ion battery scrap after the environment is able to maintain a "zero emissions"?

Reporter online access to a lot of information, common argument is that lithium is not as heavy metals, little environmental pollution. But one expert said in an interview with reporters, although lithium-ion batteries do not contain mercury, cadmium, lead and toxic heavy metals in large, but the lithium-ion battery anode material, electrolyte solution and other substances in the environment and human health still significant impact. Thus, by standard methods of lithium battery recycling and the environment to avoid further pollution is imperative.

Scrapped due to the current lithium-ion batteries are not part of the state's hazardous waste, which indirectly helped in the recovery of waste management of lithium blank. Reporters found through interviews with the current state does not expressly provide waste lithium treatment.

Ankai Automobile Co., Ltd. Wang Xianfeng, deputy party secretary, told reporters, the national standards set forth in automotive batteries saturation less than 70% to 80%, the energy can not be used for car storage. In order to reduce the user cost of a single car, Kai and battery manufacturers and users using the annual lease fee of battery, the battery will be used by the battery manufacturer itself.

The Shenzhen Wuzhou Dragon bus, a staff member told reporters that the company has been in pre-market battery manufacturers with customers and to reach agreement through consultation, two years after the purchase of electric vehicle battery from the battery factory for recycling. However, battery manufacturers can provide users with updated services and payment collection costs is not clear, but also based on two years of technical level and product pricing decisions.

But experts said that the bus industry, due mostly to consumers of electric passenger bus company, if the development of appropriate standards, the implementation is not difficult.

Battery Recycling subsidized foreign

At present, some foreign countries in the recycling of waste batteries have performed a series of active exploration, and accumulated a lot of good experience. Such as the United States, Japan, submitted to waste battery recycling company after processing, each dealing with a ton Government to give some subsidies; Korean production of battery manufacturers, for every ton to pay a certain amount of margin used to pay recyclers to handle the fees, and appoint a special plant for processing; Some battery manufacturers state taxes or impose environmental management of battery disposal companies tax breaks and so on.

Reporters also learned through interviews, to see from the current battery life, three years is basically a cap and a bus in operation is the normal life cycle of 8 years, which means that new energy bus "life" usually need to replace 2 3 batteries, battery cost and maintenance cost is very high. Allegedly, during the Beijing Olympic Games to run the new energy bus, vehicle battery price is only several hundred thousand dollars. High battery prices are likely to become the new energy bus industry the process of stumbling block. The main consumers of new energy bus - bus companies also hope that the battery factory and manufacturers together to find ways to reduce the battery's and then spending. Dingli school said, "reliability can only really benefit the user's product, to get to users, will move toward industrialization."

Lithium battery materials industry: the road twists and turns a bright future

Lithium battery materials industry: the road twists and turns a bright future

Speaking note of the meeting

Small lithium battery industry in the 1990s are now at a mature stage. Lithium battery research since the 1970s, but until the 1990s, security remains unresolved, mainly due to the use of lithium metal anode material, easy to explode. SONY as a company until the carbon anode materials, the safety issues have been resolved, since the lithium batteries in computers, mobile phones, digital cameras and other areas to be universal.

Traditional energy sources are depleting, power lithium gotten greater attention, the rapid development of the field of cathode materials. Small lithium and lithium cobalt oxide used as the anode and cathode carbon materials, but if the application of new energy vehicles, the following problems: First, as a scarce resource of cobalt, high cost; second car in the process of acceleration and deceleration to bring high-current charge and discharge , deposition of lithium in the anode, thereby supporting grain production, through film, causing the battery short circuit, high-calorie organic electrolyte under the conditions in the explosion. From the 1990s, the United States invented the Goodenough professor of lithium iron phosphate, the material rate performance, high current density does not change the structure, allowing lithium battery in the power of applications possible. Lithium iron phosphate, but there are many problems need to be resolved: low voltage (3.3V, lithium cobalt oxide is 3.7V), low energy density.

Although the defective power lithium present, but the problem can be resolved in the development of the industry next great career. Battery as a system, although the cathode material developed rapidly over the past few years, but the diaphragm, electrolyte, cathode, there are many problems to be solved. 1) There are many kinds of lithium battery cathode materials, the most important is carbon, which application is more middle-carbon-dimensional ball, this has been the industrialization of Shenzhen BTR. However, applications in the power needed to solve the large lithium charge-discharge current density the deposition of lithium in the anode material issues; 2) currently meet the small lithium electrolyte applications, but applications in power need to be modified on lithium, flame, etc. research; 3) high-temperature polymer membrane obturator also need to avoid short-circuit and other aspects to be improved. Short term, there are still many problems power lithium, but Should look long term, as technology continues to develop, the industry's future promising future.

Fluoride short-term valuation is reasonable, long-term value remains to be seen lithium hexafluorophosphate progress of the project of aluminum fluoride Fluoride is currently ex-factory price in 7500 yuan / ton, down again last week, a large number of primary and pre-stocking the downstream manufacturers; cryolite remain relatively stable In 6700 yuan / ton, we mentioned in previous reports, this year because of lower operating rate of the aluminum industry and put on some of the new capacity comes on stream, cryolite obvious gap in the short term needs. Inorganic fluoride for 10 years, 1.05 yuan, 1.38 yuan of 11-year forecast, because the first industry to maintain 10% growth, followed by the company with cryolite circulation process routes, and cost advantages of anhydrous aluminum fluoride higher than the industry growth is expected to achieve speed; for lithium hexafluorophosphate is currently conducting equipment installation, according to the Taurus experience, because the lithium hexafluorophosphate special production process, equipment needed for non-standard transformation, the transformation effect to be seen, so the uncertainty is relatively large piece of business.

How to use a nickel-metal hydride battery design of ultra-bright LED lights

A Ni-MH battery voltage is only 1.2V, and 3.3V Ultra Bright LED above the operating voltage required to ensure sufficient brightness. So. Must find ways to increase the voltage, the common boost circuit generally have two forms, namely high-frequency oscillator circuit and electromagnetic inductive boost circuit. For the boost circuit, two circuits to choose from.

Figure 1 circuit uses a small pulse transformer, high frequency oscillation power tube VT3 will signal amplification, the increase in L1 through direct step-up transformer T.

Figure 2 is the use of self-inductance of the inductor to achieve high voltage upgrade. When the oscillation signal input VT3's base when, VT3 will periodically saturated end. When saturated, the inductance L power, electric energy into magnetic energy stored in L, then the diode cut-off, the energy stored by the C3 power to the load; when the deadline VT3. Inductance will result in lower self-induction electromotive force is on the negative. VD diode conduction, the superposition of self-induction electromotive force electromotive force and to charge capacitor C3 and the load, force is due to two strings. Can be even higher than the supply voltage, the specific size of the load and VT3 mainly by the saturation current through the inductor L when the ratio determined.

Both circuits can be increased to 3.3V above 1.2V, the first circuit in the transformer if the positive feedback on the increase around the coil. Oscillation circuit can be removed. Make the circuit more compact. However, the use of this circuit calculations more complicated. Difficult to adjust the output power, the transformer winding also some trouble. The second only a small inductor. Inductance and no large requirements, regulating the inductor current drive, you can easily adjust the output voltage. In this use of the second circuit.

Oscillator circuit shown in Figure 3, although able to work in 1.2V voltage oscillator circuit there are many, but proven, making the circuit of Figure 3 is easy, simple calculation. High success rate. Oscillation frequency is also easy to determine. And. Adjust the size of the R4, you can not affect the signal frequency in the premise of regulating signal range, so use this circuit to generate a high frequency square wave pulse to prepare for the step-up circuit. As a result, the circuit design is completed by Figures 2 and 3 together constitute.

On the circuit parameters, which lies in power. Inductive power, the stored energy is E = LI2 / 2, Let f be a square wave frequency, 1a within the switch will turn f times, so. Inductive energy stored per second is W = f x E, set the load to the energy conversion efficiency n, then the output power P = n x W + Po, Po is the power supply power directly to load (because the power and self-inductance high-voltage overlay must consider this point).

Now be estimated. Drive an LED to about 100mW. Power Po is about 20mW. In order to ensure the supply, calculated according to P = 100mW. Take n = 80%, then just find a few hundred uH inductor, such as the 500 uH: On the other hand, according to the conservation of energy. 1.2V to 3.3V is about 3 times. Then due to efficiency. Inductive drive current to LED current of about 3-4 times, it is taken as 120mA, this way. Can calculate the oscillation frequency of 34kHz or so, so, take R = 2kn, C = 0.01 uF will be able to meet the requirements. Determine the parameters. Can be high not low frequency, inductive rather large not small, so as to ensure the output power is large enough to have enough adjustments.

As the circuit is simple. Components in the 2 x 2cm board. As long as the correct operation, the power circuit can work. Do not connect the first LED, the output voltage is measured with a multimeter, this time, adjust the size of R4, R4 greater the output voltage is smaller. And vice versa, when the output voltage is 3.2V or so, you can connect the LED, and then adjust the size of the R4, it is sufficient light, note that the voltage across the LED can not make more than 3.6V, otherwise it may burn LED. As a result, the circuit will be completed commissioning.

Battery type, model and method of cleaning and maintenance

1 Chemical Battery

Is through the electrochemical reaction, the positive and negative active material of the chemical energy into electrical energy of a class of devices. After a long research, development, ushered in a wide variety, widely situation. As large a building can only accommodate was the next great device small enough to breed in millimeters. all the time for a better life for our service modern electronic technology, chemical batteries, made of high demand. every chemical battery technology breakthroughs have brought the development of a revolutionary electronic device the modern society, people, everyday life, more and without chemical batteries. electrochemical many scientists the world now, the interests focus on the chemical as a battery electric vehicle area.

2 batteries and liquid battery

The distinction between dry and liquid batteries battery is limited to the early development of that period.'s First battery from the glass container filled with electrolyte and two electrodes and later launched a paste electrolyte-based batteries, also known as dry .

There are still "liquid" batteries. Are generally very large size species, such as those used as an uninterruptible power supply in large stationary lead-acid batteries or solar cells, supporting the use of lead-acid batteries for mobile devices, some using the full sealed, maintenance-free lead-acid batteries, these batteries have been used successfully for many years, sulfuric acid electrolyte which is fixed by the silica gel or glass fiber separator suction pay.

3 disposable batteries and rechargeable batteries

Disposable batteries commonly known as "disposable" batteries, because their power is exhausted, you can not recharge using only discarded the common disposable batteries, including alkaline manganese batteries, zinc-manganese batteries, lithium batteries, silver zinc batteries, zinc air batteries, mercury batteries and magnesium zinc manganese batteries.

Rechargeable batteries made by different materials and workmanship, the common lead-acid batteries, nickel cadmium batteries, nickel-iron batteries, nickel metal hydride batteries, lithium-ion battery. The advantage is long life cycle, they can charge and discharge more than 200 full- Some rechargeable battery power than most of the load off the battery high ordinary nickel-cadmium, nickel metal hydride battery, the unique memory effect, causing inconvenience of use, often causing premature failure.

4 Fuel Cell

Fuel cell is a fuel's chemical energy through electrochemical reaction directly into electrical energy

5 dye-sensitized solar cell battery

Models are generally divided into: 1,2,3,5,7 No. 5 and 7, which is particularly common, so-called AA batteries is 5 batteries, and battery AAA battery is 7! AA, AAA is the battery model.

For example:

AA is what we usually refer to the battery 5, the general dimensions: diameter 14mm, height 49mm;

AAA is what we usually refer to the 7 cells, the general dimensions: diameter 11mm, height 44mm.

The following is from the site: Ni-MH battery forum for users to add

Knowledge of a number of attached cells:

Talk about the common "AAAA, AAA, AA, A, SC, C, D, N, F" these models

AAAA type rare, one-time AAAA Energizer Alkaline batteries can occasionally see the general use of the computer pen inside The standard AAAA (flat) battery height 41.5 +/- 0.5mm, diameter 8.1 +/- 0.2mm.

AAA type battery is more common, general use of the MP3 are AAA batteries, the standard AAA (flat) battery height 43.6 +/- 0.5mm, diameter 10.1 +/- 0.2mm.

It is well known even AA batteries, digital cameras, electric toys and ultimately AA batteries, standard AA (flat) battery height 48.0 +/- 0.5mm, diameter 14.1 +/- 0.2mm.

Only one type of battery A is not common, usually for the series inside the battery cell battery pack, I often give others the old camera for nickel-cadmium, nickel metal hydride battery, almost all of 4/5A, or 4/5SC battery Core Standard of A (flat) battery height 49.0 +/- 0.5mm, diameter 16.8 +/- 0.2mm.

SC models are not common, generally is the battery pack inside the battery cell, mostly in power tools and cameras and can be seen on imported equipment, the standard SC (flat) battery height 42.0 +/- 0.5mm, diameter 22.1 +/- 0.2mm.

C Type II is the battery, use a lot of standard C (flat) battery height 49.5 +/- 0.5mm, diameter 25.3 +/- 0.2mm.

D Model One is the battery, wide range of uses, civilian, military, specific DC power supply can be found in D-type batteries, standard D (flat) battery height 59.0 +/- 0.5mm, diameter 32.3 +/- 0.2mm.

N models are not common, I do not know what things there with the standard N (flat) battery height 28.5 +/- 0.5mm, diameter 11.7 +/- 0.2mm.

F type battery, it is electric bikes, battery of a new generation of products, a great trend to replace lead-acid maintenance-free batteries are generally for the battery cell (personal opinion: In fact, a big, bad alone, huh). standard N (flat) battery height 89.0 +/- 0.5mm, diameter 32.3 +/- 0.2mm.

We note that (flat head) word, referring to the cathode is flat, not protruding, used to make the battery pack using the battery cell spot, the general pointed to the same model (which can be used as a single battery-powered), in height to more 0.5mm. so, I do not elaborate. Also, when the battery is not a lot of neatly "AAA, AA, A, SC, C, D, N, F" the main model, but also often have scores in front of "1 / 3, 2 / 3, 1 / 2, 2 / 3, 4 / 5, 5 / 4, 7 / 5", these scores represents the height of the corresponding cell body, such as " 2/3AA "is that high is usually AA batteries 2 / 3 of the rechargeable battery; Again" 4/5A "is that high is usually A battery of 4 / 5 of the rechargeable battery.

There is also a model representation, is five digits, for example, 14500,17490,26500, first two digits refer to the pool diameter, is the pool after the three-digit height, for example, 14500 refers to AA batteries, or about 14mm in diameter , 50mm high.

Solar thermal energy generation is becoming the new hot spot

China Academy of Engineering in the conduct of the "five" strategic development of key emerging industry consulting and research projects - a new energy industry group project meeting, solar thermal power generation has been called for a detailed statement as a key

Solar thermal power generation is becoming the new energy investment.

"Solar thermal power generation is the next blue ocean of new energy investment." May 10, 863 solar thermal power projects in general, head, Institute of Electrical Engineering Chinese Academy of Sciences researcher Wang Zhifeng told reporters.

Day, "five" strategic development of key emerging industry consulting and research projects - projects of new energy industry group meeting in the Chinese Academy of Engineering, solar thermal power generation as a priority by requiring detailed statement.

"From September last year to early this year, (China) solar thermal power generation project added 3GW (300 MW)." Intermittent at the meeting, the National Energy Advisory Committee of experts, an expert said that these projects have been completed the project proposal books, not including the private operation of several power giants did not open the project. "Once the concession tender, these projects will emerge."

"(Inner Mongolia 50,000 kilowatts thermal power project concession) should be the end of May or early June." Renewable energy National Energy Board, told reporters at a person, which is China's first thermal power projects in light of the concession bidding, "the intention of the company very much sexual contact."

"This (concession) will not only lead to the awakening of solar thermal power industry, but the whole awakening of thermal power generation chain." Wang Zhifeng said, even with the electricity companies, equipment manufacturers, banks, investors are awakening, " Consulting (thermal power) too much, I received several call people a day. "

Thermal spring

In the obscurity of many years, solar thermal power generation is becoming the protagonist of the new energy sector.

Prior to this, solar power mainly in the form of photovoltaic power generation, namely the use of solar cells, light energy directly into electrical energy. International Solar Energy Society (ISES) statistics show that in 2009 alone, the global PV installed capacity exceeded 600 million kilowatts.

And PV compared to solar thermal power is collected by large-scale solar thermal energy lighting mirror array through the heat exchanger device to provide steam to drive conventional turbine generator to produce electricity. ISES data show that the end of 2009, and the global network has been installed capacity of solar thermal power plant about 70 million kilowatts.

"Solar light and heat than the slow mainly due to the impact by the technical level." ISES executive director of the long 克里斯汀霍 Ensi Tan told reporters that the station's large scale integration technology affected the development of large-scale solar thermal power plant.

According to theory of solar thermal power, solar thermal power stations in addition to the daytime heat, light pole direct-drive steam turbine power generation, while some of the heat will be stored in a giant heat storage system in the evening can take advantage of regenerative power.

"Related has been the subject of research, there are at the laboratory stage, large-scale power system will take time." State Department counselor, director of the National Energy Advisory Committee for Xu ingot say so.

Even so, solar thermal power is still seen as "saving the earth" energy.

"The first is as light and heat and thermal power generation by steam turbine, so the ratio of photovoltaic, wind power is more conducive to the stability of power systems; followed to avoid the expensive photovoltaic silicon photoelectric conversion, cost savings and avoid pollution. " Ensi Tan said currently the world's solar thermal power plant proposed total installed capacity of more than 12 million kilowatts.

In fact, the United States and Europe have begun to solar thermal power generation as a future alternative to traditional energy sources dominant choice.

July 2009, European countries jointly launched "European desert action", governments and enterprises in the next 10 years, invest 400 million euros, in sub-region to establish a large solar thermal power plant, the project will meet all of Europe at least 15% of the electricity demand.

"Solar thermal power will become the new energy of the most important source of energy, even in the future as the largest share of China's dominant energy source." May 12, the aforementioned national energy advisory committee of experts, experts say, in foreign countries have already launched a large-scale light thermal power base in the context of the Chinese optical base is also a feasibility study in progress.

"Solar thermal power generation, once started, the speed of its development and future prospects are difficult to compare the PV." Emperor Ming Huang Ming Solar Energy Group chairman, told reporters, many countries and regions have begun to encourage solar thermal, photovoltaic restrictions. California planning requirements by 2030, solar thermal power and photovoltaic power generation installed capacity ratio of 4:1.

"'Twelve Five' (2011 ~ 2015), the light and heat will be a explosive development." Aforementioned Expert Advisory Committee of the National Energy experts say.

Power giant brainer

Sensitive power giant had brainer.

"The major Power Group has started enclosure (thermal power) of the." China Electric Power Research Institute, a solar thermal power generation experts told reporters that solar thermal power generation is relatively high resource requirements, to have cheap land, cheap water, abundant light, and relatively flat topography. "The development of the country suitable for light and heat resources are also limited, and who should give this land on the project who, we naturally swarm."

"Almost half a year thing, three or four items on the GW cropped up." Solar thermal industry, Ministry of Science and Technology Innovation Council of the League official said, three years ago, five Huadian Power Group, only to follow the Chinese Academy of Sciences to do a demonstration project, "Other companies did not even touch the power light and heat."

Huadian Group has been a walk in the first solar thermal power generation, the fastest power giant.

In 2007, the state starting in Beijing Yanqing 1 MW solar thermal power generation demonstration projects, followed by China Huadian Group, began to actively layout, now in Langfang, Hebei, Gansu, Jiayuguan, Xinjiang, Golmud and other solar thermal power to carry out preliminary work.

December 17, 2009, Huadian New Energy Corporation and the Australian Lions International signed a cooperation agreement, the two sides work together to develop plans to Golmud one million kilowatts thermal power projects.

A month later, January 5, 2010, Huadian Energy Company has signed with the Jiayuguan total over 26 billion yuan of the strategic cooperation agreement, including the development of solar thermal power generation in the city.

China Electric Power Research Institute of the aforementioned experts told reporters that the major power group has its own solar thermal power generation demonstration projects, "although only a small demonstration project, but (Power Generation Group) are a large number of follow-up reserved for the expansion of the land."

Involved Guodian Turpan solar thermal power, told reporters that China Turpan thermal power project is only 100 kilowatts, "how there are a few acres of enclosure is to the future large-scale expansion."

"The high cost of PV is a single, large costs are also high; and small-scale solar thermal is the high cost, but as long as large-scale, tens of megawatts, or even hundreds of megawatts of low cost of GW." Said Huang Ming , power companies must be based on demonstration projects to expand the scale of this is to reduce the cost of the inevitable choice.

"If you build a 100 MW solar thermal power plant, the upfront investment which can be controlled at 15,000 yuan to 20,000 yuan / kW, the tariff is probably seven or eight cents (per kWh)." Above the solar thermal industry innovation strategic alliance official said, more than the PV project Dunhuang 1.09 yuan / kWh of electricity more competitive.

The cost factors and the "area is king" ideology of domination, power companies are in demonstration projects based on the accumulation of a large number of follow-up expansion of the land.

"We can along the Qinghai-Tibet, the new road layout of solar light blue mirror array." Huadian New Energy officials told reporters that many parts of the west side of the road are the desert, "think how many rows are OK."

"Gobi with 80,000 square kilometers (thermal power) generation of electricity, can be equivalent to China's annual power generation capacity in 2008." Zhi-Feng Wang said the Chinese Gobi desert, more than 1.3 million existing square kilometers, Electrical Engineering, Chinese Academy of Sciences's research shows , "exceeding 30 million square kilometers of desert suitable for solar thermal power generation."

More and more power companies are eyeing the west, into 2010, in addition to five major power, the Tianwei change (600550.SH), the United States and other enterprises eSolar has announced its entry into solar thermal power generation.

"(Solar thermal power generation) enclosure boom has only just begun it, the next two or three years to reach its peak." Aforementioned National Energy Expert Advisory Committee of experts told reporters.

Equipment manufacturers to seize the opportunity

New industrial equipment manufacturers to bring great business opportunities, and a large number of companies are trying to share the attractive "cake."

"Solar thermal power generation in the next two years and then increase forty-five MW is not a problem, these plants are definitely involved in no less than 100 billion yuan of investment." Beijing Jiang Hi-tech, general manager of the new energy company, said more than information. In the foreseeable future, solar thermal power generation, "cake" will no doubt be more substantial.

"We also feel very tight, a great chance, we are now ready to greatly expand the laboratory." Said Huang Ming, Huang Ming Group is the world's only solar thermal power generation can produce the core steel business, "Our production capacity is not only tens of thousands of meters. "

And feel the same urgency of Emperor Ming Group, a large number of Chinese solar companies have also joined the solar thermal power development.

"Can not say more than 5,000 solar thermal companies are doing, but at least we have this idea." Solar thermal Professional Committee of China, an official told reporters, many companies have created semi-public sample.

"Solar thermal power generation are high-tech industries, such as water heaters, as if the flood, this is definitely not a good thing." He said.

Research and development companies to seize the one hand, the other is active investors cut.

"We (and Wong Ming Group) have reached an intention, Huang Ming ready to set up solar power company." May 11, Beijing, Jiangsu Hi-tech investment company official told the "Financial State Week", the two sides will set up a joint venture company, dedicated to solar thermal power generation equipment manufacturing.

"Now companies can not be too much equipment, but the future is certainly a lot there." I said hearing, as the equipment manufacturing technology maturity scale solar thermal power generation and expansion of solar thermal equipment manufacturing industry will certainly attract a lot of investment. "Many U.S. companies are also seeking to cooperate with us."

"Various parts manufacturing companies have large numbers, and some companies have begun to be eliminated." Beijing Yanqing 1 megawatt solar thermal power generation demonstration project leader told the "Financial State Week" in 2007 for lighting the mirror project procurement ultra-white glass, there are only a Beijing-based company to supply, the price of 300 yuan / square meter, the procurement of this project over 10,000 square meters of glass. "Of the many companies can produce the specific optical glass."

Foreign equipment manufacturers of light and heat has also been eyeing the Chinese market. January 9, 2010, the U.S. supplier of solar power eSolar with Shandong Penglai Power Equipment Manufacturing Co., Ltd. signed an agreement, in addition to selling equipment through outside the power of Penglai, eSolar years the company also plans to invest over $ 5 billion, in China 200 million kilowatts of solar thermal generating units.

The upcoming concession of solar thermal power project in Inner Mongolia, it is by the German company Solar Millennium feasibility study report in the organization. "We hope to enter the Chinese solar thermal power generation market, but the situation we have to see to say." Considering the Chinese government restrictions on foreign investment in the electricity market, Solar Millennium, a cautious person in charge.

"And photovoltaic, wind power equipment 'heartless', mainly by the introduction of foreign compared to the core technology, solar thermal power generation of the country have mastered the core technology." Advisory Committee for the aforementioned national energy experts said, China has mastered the solar thermal power generation from light, heat, electricity and other aspects of the follow-up core technology, the follow-up of equipment will mainly be in the country.

"It is foreseeable that if countries do not have active policies to guide this (solar thermal power generation equipment) industry will be like wind power, polysilicon, as duplication, excess capacity." Foregoing the use of solar thermal Professional Committee of China's official said.

HP laptop battery recall: show or?

Recently, HP announced a worldwide expansion of its laptop battery recall program, the six new products, and some of the battery into the battery recall, the Chinese market is also within the scope of the recall. For this initiative, many people have doubts that HP is in the show. I believe that the HP laptop battery recall is not in the show, but in order to prevent the battery caused the fault, the customer is responsible for this should be a measure.

By 3.15 events, many people have begun to see HP with a colored glasses. Because of this, many people would think that HP notebook battery recall practices in the show. Look at the reasons for HP notebook battery recall, I believe we will not have the views of Hewlett-Packard in the show.

Hewlett-Packard official, said: "The recall program is HP with the U.S. Consumer Product Safety Commission and other competent bodies to make safety-Packard and battery manufacturers that certain notebook computer products in the assembly of some of the battery pack may customers pose a potential security risk of these batteries may overheat, customers constitute a fire and burn hazard. "

Strictly speaking, this is not a real recall, because the recalled products are all quality defects or safety hazards of products. The HP's battery recall, there may be security risks is just the product, rather than the products identified security risk. If so, why HP has recalled these batteries?

For consumers, there may be a security HP recall dangerous products, is an initiative of the customer is responsible, which is a reflection of HP's service quality. The reason why many people have doubts about HP's battery recall is not understand, since the uncertainty batteries pose a potential safety hazard to sit, why HP recall it?

Some people think that HP may be the reason why these problems notebook battery recall, largely to take preventive measures. Have to admit, NVIDIA graphics quality problems caused by the 3.13 incident on the Hewlett-Packard had a very large negative impact, the HP may be a security risk to the battery recall, and highlight the quality of HP products in the protection of the cautious, after all, Hewlett-Packard fear of recurrence of quality problems. To eliminate the possibility of a very small probability, the HP would rather spend money in advance to prevent possible security risks, which is HP's notebook battery recall true intentions.

Objectively speaking, HP's recall of some laptop batteries may be a problem, on the one hand is used for the sake of customer safety, but also to other HP brand sake. The recall of notebook batteries, the user is the biggest beneficiary. Users benefit from a market move, how is the show it? If the battery recall is a show, then this world there are too many vendors in the show. Therefore, I believe that the HP notebook battery recall, not just for show, but a very attentive customer care program.

Very promising lithium battery industry

2011-08-01T18:14:00.000+08:00

Very promising lithium battery industry

Li-ion battery is developed in the 1990s a new type of green secondary battery, the rapid development of the last decade, in a small secondary battery market accounted for the largest market share, has become the field of chemical power applications the most competitive battery .

Currently, lithium-ion battery development presents a situation in several directions simultaneously. The main difference lies in the direction of the cathode material used in the different. In all lithium battery cathode materials, suitable for use as battery materials are lithium manganese oxide, the three elements of lithium iron phosphate material and three.

Domestic lithium battery cathode materials are mainly related to listed companies mining in Tibet (000,762, stock it), Shanshangufen (600,884, stock it), CITIC Guoan (000,839, stock it) and China Baoan (000,009, stock it) and so on. Among them, the Tibet Mining major advantage with the upstream raw materials, the company has Zabuye Salt Lake (proven reserves of over 2 million tons of lithium carbonate) 20-year mining rights.

CITIC Guoan owned CITIC Guoan MGL since 2002 has assumed the "lithium-ion battery cathode material - lithium manganese oxide of industrial technology development", "pure electric car with lithium-ion battery industry R & D", etc. major IT projects. CITIC Guoan also has a lithium battery materials, resources development, development and production of Qinghai Guoan is the key raw materials, lithium battery cathode material lithium carbonate. Although the company's production of lithium carbonate is also only a few thousand tons, but the company's design capacity of 25,000 tons / year, the future development potential.

Shanshangufen has been built from the anode material to cathode material, electrolyte and then a complete system. In the cathode material, the company has become the largest, world's third largest supplier of cathode material. Has now mastered the technical preparation of lithium iron phosphate.

China Baoan has initially playing a full battery materials industry chain is the lithium iron phosphate cathode material standard setters. BTR company holding 55% of the cathode material lithium iron phosphate company's production capacity has reached 1,500 tons / year, holding 75% of the company's main ternary Tianjiao cathode material sales in 2008, ranked the first, up to 30% market share ~ 40%.

Also, is the first production Shanshangufen CMS (mesophase carbon microbeads) of the domestic manufacturers, the current annual capacity of 12 tons. In artificial graphite and natural graphite carbon anode material system has a strong field strength.

Affect the performance of lithium electrolyte is another important material, accounting for about 12% of the cost of lithium batteries. Which lithium hexafluorophosphate is the core of the electrolyte materials, accounting for about 50% of the cost of the electrolyte. As the technical difficulty of producing very high in the international arena from the east electrochemical industry, SUTERAKEMIFA, Morita chemistry, several Japanese companies a monopoly. Taurus Tianjin, China currently only has 80 tons capacity, and all were occupied. Jiangsu Guotai (002,091, it shares) owned Huarong Chemical Co., is currently the largest, highest grade lithium battery electrolyte product manufacturer. The company is building "300 tons of lithium hexafluorophosphate project." Shanshangufen belongs Dongguan electrolyte Shanshan is the second largest producer, currently has an annual capacity of 1,500 tons of electrolyte. The current worldwide market supply and demand balance electrolyte, and cathode materials, mainly by the stock lithium battery market, the next increment of market power depends on lithium battery market.

In addition, the energy reserves in the field of lithium batteries also have important applications, the first peak electricity grid can be adjusted to solve problems. Second, clean energy such as wind, solar and tidal energy are intermittent energy sources, the lithium energy storage device with the use of clean energy, energy storage in power generation, energy released during the break, can effectively alleviate the energy shortage in China the status quo.

Conjecture: buy low, sell new energy battery industry stocks?

New energy into the battery business will be to the explosive growth this year, the eve of the high growth prospects for the future is very optimistic. The more upstream of the lithium battery industry, which shares more facing a bright future, it is also more fluoride than other industry-based shares soared, Thinking in this manner, the electrolyte membrane technology Fosugufen, Shanshangufen advantages of raw materials Jiangsu Guotai, Zhou state and other varieties of new tracks, and has two battery materials, and the recent listing of China Baoan when the rise of technology, Fluoride, today traded ninety-nine long time can also be tracked.

Comments: After nearly two days A-share market rebound, the market is expected to appear today in Shanghai and Shenzhen will be the pattern of differentiation, in which the new shares or energy battery industry will continue to be active, because the media reported the Shenzhen electric car as a taxi information means that the new energy vehicles have been his breakthrough in the industrial stocks, which means that the new energy battery industry will be faced with the prospect of a broad, because there is a phone with a lithium battery electrolyte, only 4 grams, but the power cars, especially the bus, to reach 40-50 kg, the general family car, also 20 kg of the diaphragm and other related industries as well. Therefore, new energy into the battery business will be to the explosive growth this year, the eve of the high growth prospects for the future is very optimistic. The more upstream of the lithium battery industry, which shares more facing a bright future, it is also more fluoride than other industry-based shares soared, Thinking in this manner, the electrolyte membrane technology Fosugufen, Shanshangufen advantages of raw materials Jiangsu Guotai, Zhou state and other varieties of new tracks, and has two battery materials, and the recent listing of China Baoan when the rise of technology, Fluoride, today traded ninety-nine long time can also be tracked.

U.S. astronauts to the station a new battery

2011-07-28T14:29:00.000+08:00

U.S. astronauts to the station a new battery

WASHINGTON, May 21 (Xinhua): The United States, "Atlantis" Space Shuttle crew of two astronauts conducted 21 since launch the third and final spacewalk for the space station's two solar panels installed new batteries.

This task is the "Atlantis" mission specialist Michael Good and Catelaymen. They installed new batteries each weighing 170 kg and cost up to $ 3.6 million, removing the old battery will be shipped back to Earth. In addition, the two astronauts for the space station cooling system is also connected to a new cable.

"Atlantis" for the ISS trip of six new batteries, and another astronaut Michael Goode Stive spacewalk in 19 has been installed 4.

Space station solar panel battery has been in service for 10 years. NASA hopes the space shuttle before retiring end of this year, these batteries "new for old." Launched in July last year, the "Endeavour" astronauts have replaced the six batteries.

"Atlantis" No. 14 from Florida's Kennedy Space Center launch to the International Space Station, the 12-day mission, the main task for the ISS Russian-made "Dawn" was a small test module, solar cell and Ku-band antenna and other key components and goods.

This is the "Atlantis" in service since 1985, the first 32 flights, is also planned last time. "Discovery" and "Endeavour" will be held in September, the final flight in November, followed by the U.S. space shuttle will be retired.

Summer electric car battery maintenance

How do battery maintenance, the experts put forward five suggestions:

1, avoid loss of power storage, loss of power state refers to the battery did not charge the battery after use, prone to sulfate, lead sulfate crystals attached to the plates, electric plug ion channels, resulting in lack of charging, the battery capacity decline. Loss of electrical idle state longer, more serious damage to the battery. Battery idle, should be charged once a month, which can extend battery life.

2, periodic inspection, during use, if the continued line of electric bicycles a sudden drop in mileage in a short time more than ten kilometers, it is likely that at least one battery cell group appeared off the grid, plate to soften, the plate active material shedding and other short circuit. At this point, it is timely to examine the professional body repair battery, repair, or with a group.

3, not large current discharge, electric bicycles at the start, manned, uphill, it is best to use pedal power to avoid the momentary high current discharge. Easily lead to large current discharge of lead sulfate crystals, to the detriment of the physical properties of the battery plate.

4, control the charging time, under normal circumstances the battery is charging at night, the average charging time of 8 hours. If the light discharge (charge mileage is very short), the battery will soon be filled, there will continue to charge the phenomenon of overcharging, resulting in battery water loss, fever, reduced battery life. Therefore, the battery to discharge depth of 60% -70% of the best one charge, the actual mileage can be converted into riding, charging according to actual conditions necessary to avoid damaging charge.

5, to prevent heat exposure, electric vehicles is prohibited in the sun exposure. Temperature conditions may cause the battery leaving the battery internal pressure increases the pressure limiting valve is forced open automatically increase the battery is a direct consequence of water loss, and excessive water loss will inevitably lead to battery battery decreased activity, accelerated softening plate, charging shell body heat, from the drum shell, deformation and other fatal injuries.

Air lithium batteries: electric cars tomorrow?

In France, Argonne researchers are the initial development of the air battery, according to some scientists, this battery will be over the existing electric vehicle battery pack 100 times the energy storage capability.

According to this plug-in electric car market reaction, can not know whether the user is really high for the current price of the car battery and its limited storage capacity pay. Although the new generation of lithium batteries in the past 10 years has been leaps and bounds, but it still exists limitations, can not meet the needs of many users.

If the lithium batteries can be lighter, cheaper, and can reach its storage capacity of the Chevrolet Volt, Mitsubishi i-MiEV, Nissan Leaf five times when the situation then?

Aragon lab officials said, the air above-mentioned lithium battery can achieve these goals, or even more, now that the project has received $ 8.8 million of government funding.

Ordinary lithium battery is moved out through the carbon rod anodes of lithium ion through the electrolyte (usually a lithium salt) to the cathode metal oxide. Air lithium-ion batteries use a lithium anode and porous nature of the cathode carbon rod, so that the supply of lithium ion through the oxygen to achieve freedom of movement. The difference is, in layman's eyes, this is the breathing air of lithium ion batteries, lithium ion battery capacity is determined by the size of the lithium-ion cathode contains the number of how many. This structure can make the battery smaller, lighter and there may be more expensive. Another may be installed on the battery electric cars more power to travel 100 kilometers on one charge or more.

Air lithium-ion technology is still in its early stages, but with the development of clean energy technologies, the world's major institutions and auto manufacturers are struggling to find the future direction of electric vehicles. Most experts have said that battery technology for 10 years (or even 20 years) to really reduce the cost and really put into use.

The federal government for similar air battery technology, battery technology with confidence, and will soon be an additional $ 34 million in funding for the vehicle battery research and development.

Electric cars become mainstream battery disposal test Governments

Electric cars become mainstream battery disposal test Governments

In the traditional vehicle life to a close, people coming era of much-anticipated electric car, including the 2011 listing of Nisaan pure electric vehicles Leaf, the Chevrolet Volt electric car abundance Prius plug-in hybrid car and so on. As a core component of the battery is a lot of institutions and investors are optimistic.

However, people are increasingly concerned about a problem: so many battery electric vehicles will be another burden on the environment? You know, a small button battery can be about 60 million liters of water pollution, equivalent to the amount of water your life; while a conventional battery No. 1 mercury rot in the ground, to make around 1 square meter any agricultural land lost value. The current EU countries sold 800,000 tons per year car batteries, 19 tons of industrial batteries and 16,000 tons household batteries. When the electric car era, the global figure will be more terror.

If the battery pack that used to be like garbage heap by the roadside, but also an exaggeration. Even when the car battery life after the end of a lithium-ion batteries used still retains most of its energy storage capacity. Many analysts have forecast, after 2010, the secondary market for used batteries will grow substantially.

However, opponents fear that once this becomes a reality, we need a lot of infrastructure to collect these waste batteries, and also re-evaluate their value, and then re-sell them to consumers. This can be achieved in the short term it?

Was right, but now there is a ready example is the car to start the car loaded for the regular 12-volt lead-acid batteries. This battery is loaded every year to 70 million new vehicles built, it contains lead and sulfuric acid, is a garbage dump in one of the most dangerous items.

According to the U.S. Environmental Protection Agency statistics, only in the United States, almost every year takes 100 million vehicle start battery, of which 99% has been recovered and recycled. Because users in the U.S., if not to return used batteries manufacturers, retailers or wholesalers, each bought a new battery will need to pay 3-5 U.S. dollars.

A conventional 12-volt battery, nearly 97% of the lead can be recycled. The electrolyte, in particular, sulfuric acid, can be in and then put to other use, such as conversion into sulfate, made of fertilizer, or dyes. Even the plastic battery cover, can also be reused.

China is now able to see the bike everywhere, and its batteries are mostly lead-acid batteries. Electric bicycle battery is a consumable, average about 1 year to be replaced. Luyuan Electric Vehicle Co., Ltd. Zhejiang Brand Center Manager, Xiao Ding said: "The current scrap lead-acid batteries, basically could be restored, after the repair efficiency of up to 80% of the new battery, the second repair efficiency of 50% or more."

The company's current approach is: for any brand of electric cars and cars lead-acid batteries, can still be repaired for by special technology to repair, back into use; of the damage can not be repaired completely lead-acid batteries, recovered by qualified business lead and zinc processing, refining of secondary lead.

Many provinces and cities also clear that the market for electric bicycles, purchase a new battery must return the used batteries, or not to sell a new battery.

But this recovery is not always good. Environmental organizations Blacksmith (Blacksmith) that the world's 10 worst pollution problems, one is the removal of lead-acid batteries caused the error.

There are a lot of recycling waste is the number of clandestine laboratories, they will be recycled to the lead-acid batteries do not have the conditions stored in the open space or warehouse, there is no qualification process, resulting in a large number of lead waste and waste of a lot of emissions.

In Switzerland and Japan, each dealing with a ton of waste batteries, a government subsidy of waste battery handling business about 5000 yuan; in Korea, for every ton of battery manufacturers to pay a certain amount of margin to cover recycling, processors charges and appoint a special plant for processing; Some battery manufacturers state taxes or impose environmental management of battery disposal companies tax breaks and so on.

After a long period of development, lead-acid batteries have already matured, and was once widely used to power passenger cars. But its capacity is low, bulky, polluting all the shortcomings, it was gradually abandoned by the auto companies. In contrast, lithium-ion battery energy storage unit weight is high, the price is not expensive, non-toxic. So now the new energy vehicles in general tend to use lithium iron phosphate and manganese lithium batteries.

Lithium-ion battery pack for the first time since last year to be used in the car - the first car to use lithium-ion battery car is a Mercedes - Benz S400 2009 model of the hybrid - a growing number of other cars manufacturers have begun to do the same thing.

At the same time, recycling batteries has become the electric car manufacturers can not avoid the problem. In the global hybrid market faces staggering Toyota Motor Corporation, has for its dealers on how to properly dispose of the car like the Prius as the nickel-metal hydride battery waste, and the establishment of standard procedures.

Next, we must look at the performance of governments.

Linear Technology introduced digital programmable devices LT3071 linear regulator

Linear Technology Corporation (Linear Technology Corporation) introduced a digitally programmable linear regulator family of second device LT3071, available in the current monolithic 5A LDO, the device with the lowest dropout voltage, low noise and most fast transient response. 5A when the ultra-low dropout voltage is 85mV. In the 10Hz to 100kHz bandwidth, 5A, when the output voltage noise of only 25uVRMS. With the LT3071 and its unity gain bandwidth of 1MHz minimum 15uF ceramic output capacitor, output 4.5A for a fast load step, only produces a 30mV overshoot / undershoot, thus saving a lot of body capacitance, space and cost. LT3071 is ideal for low voltage, high current devices (for example: FPGA, DSP, ASIC, microprocessor), power-sensitive communications, server / storage unit and post-high-power step-down regulator applications.

LT3071's output voltage can be digitally set, set from 0.8V to 1.8V (in 50mV increments). The accuracy of the entire line, load and temperature range is strictly defined as +/- 1%. Analog output margining function can be continuous within the range of +/- 10% output voltage regulation system, which is very beneficial when developing and debugging the system. A power good (PowerGood) mark indicates the output voltage is in a stable state, or the device is in UVLO state, the tags also provide early warning of thermal fault indication. An output current monitor supply output current proportional Dongtai that (IOUT/2500), it can be directly measured, can also use a resistor Zhongjie and converted to voltage, allowing the calculation of load or power. LT3071's input voltage range of 0.95V to 3.0V, the bias supply voltage range of 2.2V to 3.6V. Bias supply to the internal NMOS pass device provides the gate drive.

Multiple LT3071 devices can be easily paralleled to achieve higher output current and spread the heat throughout the board. Tracking can control a power supply input for the LT3071 step-down regulator. The tracking drive upstream buck regulator to maintain the LT3071's input voltage VOUT + 300mV, minimizing power consumption. If the output voltage is dynamically changed, then the tracking function automatically adjusts the buck regulator output voltage to maintain constant efficiency. Internal protection circuitry includes UVLO, the reverse current protection, with power foldback current limiting and accurate thermal shutdown with hysteresis.

LT3071 in a thermally enhanced, Flat (0.75mm) 28-lead 4mm x 5mm QFN package, E and Class I devices from -40 ° C to +125 ° C junction temperature range. 1,000-piece quantities, the price of both devices were $ 4.20 per tablet and $ 4.80.

The first electric car charging pile to start building in July

In July, the city will start building electric car charging pile 46, the ground appeared Quanzhou electric car not far away.

The first electric car charging pile

Expected to be completed in September

Recently, the provincial power company signed a cooperation agreement with the municipal government decided to start this year, the city launched a pilot electric vehicle charging facilities construction, commissioned by the provincial power company Quanzhou planning and implementation. It is understood that electric vehicle charging can be divided into two kinds of vehicle charging and battery replacement, charging facilities can be divided into AC charging pile, charging stations and battery replacement stations. Reporters learned from the Municipal Electric Power Bureau, completed this year, charging 46 small piles, which the urban 38, Southampton 4, Jinjiang, Shishi, and 2 each for a car charger for electric vehicles to provide AC power. Currently located, plans to start building in July this year, completed in September. The first charge will be selected pile Office parking lot in the power sector, government agencies and large residential area parking lot parking lot. AC charging pile fixed on the ground, using a dedicated charging port, the use of conduction, as a car charger for electric vehicles, energy exchange, and provide a friendly human-machine interface, with a corresponding communications, billing and security features.

Charging stations next year to build large-scale investment

According to reports, next year will build a large investment of nearly 700 million charging stations for electric vehicles, three or more non-car charger and (or) the exchange of charge pile composed of (at least one off-board charger) in place, the main provider of service charge, the battery rental service, battery replacement service, charging ancillary services.

Or the first electric car is on Government Procurement

Plug in, inserted into the card reader, electric vehicle charging will be as simple as car fuel. While the first charge in September after the completion of the pile, we can charge electric vehicles, but electric cars are not cheap, as can occur when the road Quanzhou electric vehicles marked with a big question mark. Currently, Beijing, Shanghai, Shenzhen and Tangshan cities have electric cars in use. It is understood that an electric bus price of 100 million. "If you can enter the country '10 City 1000' plan, subsidies for each bus can be up to 60 million, 13 cities had the honor finalists. Unfortunately, one does not any city in the province." Interested parties the power sector , low operating costs of electric vehicles, pure electric cars one hundred km fuel consumption of only one-tenth of the cost of government procurement vehicles may be a breakthrough in electric vehicles appear in Quanzhou.

Electric car known as the green car. To pure electric vehicles, for example, its energy efficiency than 7.5 percentage points higher fuel vehicles, emissions equivalent to an ordinary diesel only 2% -8%, reducing vehicle emissions, reduce oil consumption society has an important significance. Preliminary statistics, every ten thousand buses to fuel electric buses, annual savings of about 170,000 tons of fuel, exhaust gas emission reductions of nearly 50 million tons.

Vehicle charging can be divided into slow charge and fast charge, fast charge is generally 15-30 minutes to complete with a 60% charge. Slow charge is the size and power charging facilities, the size of the car power, hours vary. According to the current market slow-charge the use of pure electric vehicles on a single charge of driving range is generally 100-300 km, high-power charging facilities for the 2-3 hour charge time, charging time charging facilities for the small 8 - 10 hours.

January 2009, Ministry of Science and the Ministry of Finance jointly launched the "10 City, 1000" electric vehicle demonstration project, will use about three years time, the development of 10 cities each year, each city launch of 1000, including hybrid electric vehicles, pure electric vehicles, including new energy vehicles, and strive to make the country the size of the operation of new energy vehicles in 2012 accounted for 10% of car market share; the same time in Beijing and other cities in 13 energy-saving and new energy vehicle demonstration pilot work, promote the use of units to buy energy-saving and new energy vehicles grant. March 2009, the state issued "automobile industry restructuring and revitalization plan," clearly put forward to 2011, form a 500,000 electric, plug-in hybrid and common type of hybrid and other new energy automobile production capacity, new car sales accounted for by energy car sales total about 5% of the target.

Ma Guilong: "lithium batteries" promotion of electric vehicles long way to go

2011-07-06T12:15:00.001+08:00

Ma Guilong: "lithium batteries" promotion of electric vehicles long way to go

Ma Guilong professor at Tsinghua University, has twenty years of research dedicated to electric bikes, the industry known as "China's first electric car people." Professor Ma Guilong early inventions technology laid the foundation for industrial development and direction, and free to contribute their patents, with the results of their research to guide the development of industrial technology.

Interview Record:

First, the research process

Reporter: In your electric bicycle industry is a technology veteran, can not be introduced to the course of your research?

Malaysia: Domestic electric cars first appeared in the wheel hub motors, Tsinghua University developed a "speed switch to", "pulse width modulation" in the nineties is relatively new technology, I was as the inventor applied for a patent. 97 years after the maturity of the technology, the electric bicycle into the industry, began mass production. "Daluge", "Chizuru", "Red Flag" and other manufacturers already have some before this foundation, but are in R & D stage. In 1998 the national standard (GB17761-1999) before the promulgation of Japan November 2, 1995 adopted a national standard --- foot power, hand speed is not allowed, I and Guangzhou "Wuyang" factory, "Wei Roth, "co-production pedal sensor, passed the testing standards in Japan, and became the first export of products into the Japanese market.

Second, the "Li-ion battery technology" to promote long way to go

Reporter: In your electric bike in the next research direction? In comparison to the current industry concern, "Li-ion battery technology" to see how?

Malaysia: Many bike between the various components within the many complex routes interfere with each other, if there are problems, can not immediately identify the fault location. Research should be the next alternative chip lead, the development of "wireless LAN communication technology." For example, the console with the battery, the motor part of the no contact, but several components are connected by wireless communication technology to control each other.

In addition, people are concerned about lithium than in many technical indicators to be superior to conventional lead-acid batteries, lithium battery technology there is a significant advance. But its battery management system technology is not perfect. In the long run, the recycling of lithium batteries is a problem to be solved. Lead-acid batteries, while not a "green" battery, but can all be recycled. The lithium battery technology has not been able to do the existing recycling. The current approach to waste lithium batteries are mostly used deep approach, such an approach, while the pollution, accumulation of excess weight, up to a certain depth and temperature of the environment likely to cause the battery to explode. From this consideration, I think, the promotion of lithium battery recycling is not sound in the case of promotion to be careful, otherwise easily lead to new sources of pollution.

Third, consumers need to guard against misleading marketing slogan

Reporter: Many manufacturers claim to be "self-power", as long as the foot can generate electricity, this technology is the truth?

Ma: In the current market, many manufacturers of electric bicycles slogan unscientific, misleading consumers. Such as "self-generating type" bike, cycling can be said of human generation, that argument is no scientific basis. Only the body is equipped with energy recovery system, and only in the case of braking can be "energy recovery", the so-called "foot one step there is electricity," the current electric bicycle up and down repeatedly, the damage to the battery. The misleading propaganda of such consumers should always be vigilant to avoid fooled.

Fourth, the rapid development of China's electric bicycle

Reporter: What are the factors promoting the rapid development of China's electric bike?

Ma: In our country, to promote the rapid development of electric bicycle three factors.

First, China's traditional industries of inheritance. China has a basic bicycle, motorcycle basis for such traditional industries to modern electric bicycle business is very large.

Second, from the reform and opening up, China's rapid economic development, living standards raised, there is higher demand for travel, a huge demand for the industry.

Third, energy and environmental issues, a large number of schools, Academy of Sciences of the investment in research in this area increased. Tsinghua University, plays a technical foundation in the field work for this study provides direction for development.

And then, the development of electric vehicles are now faced with the technological updates and breakthroughs, electric bicycle models to go "light, small, energy-saving" direction, and "motor" of that section to the "greater New York moment, more climbing slope capability, cheaper materials "direction.

Fifth, China's technological level of the world's leading electric bike

Reporter: At present, the inner world of electric bikes in what position?

Malaysia: Domestic electric bicycle in a leading position in the international arena. Marked by our technology are the original and better than other countries, and we can do industrial, product reliability. America and Japan and other countries mainly rely on imports from China. However, the quality of our product needs to be improved in many irregular small factories down production costs in various ways, to engage in price competition, but also reduces the production quality. If this problem can be resolved, most likely as China's electric bicycle as a bicycle producer and exporter of power.

Worry about the outcome of new energy vehicles in the battery design weakness by

Market in electric cars, with resources far beyond the sensitivity of the power system has a network edge petrochemical system. State Grid and China Southern Power Grid in charge of the enclosure market action has been intensified, but had been hesitant in the petrochemical, oil and the two giant, CNOOC is also the "inspired" began under the layout.

2010 Deputy Minister of anus Miao Wei said in public that may be introduced within a month of private subsidies for new energy vehicles standards. However, the new energy vehicles started the best opportunity to not Ruqierzhi.

March 12, 863 energy-saving and new energy vehicles major project supervision consulting team leader Wang Binggang, said the private purchase of new energy vehicles for the subsidy standards, the Ministry of Finance may refer to "energy saving and new energy vehicle demonstration and extension of financial subsidies for Interim approach ", hybrid vehicles can enjoy the highest per 50,000 yuan of subsidies, subsidies for pure electric vehicles, $ 60,000 fuel cell vehicles subsidies for 250,000 yuan.

March 29, sources said the subsidy program will be postponed to July 1, announced by the Ministry of Finance is responsible for leading the development of the subsidy program, the NDRC, the Ministry of Science and Technology, etc. involved. Currently, subsidies, allowances and other key issues not yet agreed. The long-awaited tonic to stimulate the market again come to nothing, the new energy automotive industry in turn delayed the start.

In subsidies, charging station construction, investment structure, battery technology, policy direction, new energy vehicles that may be the pattern of restructuring of international strategic areas of the automotive industry in China still faces many variables.

Charging station explosive test the water

China's first electric car charging stations located in Shanghai Caoxi, covers an area of 400 square meters, including 4 with street street charging parking spaces, including nine charge.

The 2007 vote to build a charging station total investment of 5.08 million, of which, the charge unit cost of the study put it up to 200 million, "now we have not open to the community, mainly for the Shanghai Municipal Government bus, electric bus community, mobile Type Power Office to provide charge services. "

In charge of the bus driver said that they have options at half-price charge here later, "Our car is almost 1.2 degrees to 1.5 degrees able to run 1 kilometer, half-price if calculated by electricity, also less than 200 per day yuan. "

This site was originally charging stations belong to the state grid. Market in electric cars, with resources far beyond the sensitivity of the power system has a network edge petrochemical system. State Grid and China Southern Power Grid in charge of the enclosure market action has been intensified, but had been hesitant in the petrochemical, oil and the two giant, CNOOC is also the "inspired" began under the layout.

National Grid plans this year, the company operating in the region in 27 provinces (regions) and comprehensively promote the construction of electric car charging stations, the proposed 75 public charging stations, communication units, and some charge pile 6209 battery replacement stations. Caoxi charging station to estimate the scale of investment in 2010, the national grid in the electric vehicle charging stations, the total investment may reach 4 billion yuan.

China Southern Power Grid, said deputy chief engineer Zhaoman Yong, China Southern Power Grid Company of the first electric vehicle charging station (pile) on December 28, 2009 put into operation in Shenzhen, the scale of construction for the two charging stations, charging pile 134, total charge capacity of 2480 kVA.

Face of vigorous two incursions into the grid, Sinopec and CNPC in February 2010 is also very conservative, stakeholders were told the correspondents, their electric charging stations on the deployment of the project has no specific plans, temporarily involved.

Just two months later, the two traditional monopoly on the energy market giants himself, to invest in the arms of a huge new market.

According to the Chongqing Municipal Development and Reform Commission news, PetroChina and Sinopec intends to cooperate with Chongqing, gas stations want to increase the existing electric vehicle charging equipment. Gas stations and electric charging stations to co-operate with the existence of certain technical problems, safety technical requirements will be higher, so the cost of equipment investment will be higher than the net power input to the charging station, but the petrochemical giant has the advantage of network channels, If security problems are resolved, multi-party competition in the initiative is still occupied.

In the new energy vehicles to the mainstream trend, the power company is entirely possible to replace several major oil giant's position as the largest energy giant. The outlook for the petrochemical planes is undoubtedly the most do not want to see. Whether it is prudent to test positive, or enclosure, the new energy vehicles, multi-infrastructure market is wrestling with the next to be bombed funds from various quarters.

By weakness in the automotive battery design

New energy is the most important components of electric vehicles battery, motor and energy conversion control systems, and battery charging to achieve fast, high-performance security is the highest technical threshold, is the most concentrated part of the profits.

According to the present development of domestic technology, automotive battery design data and the actual use of the data still exists a big gap. A car battery factory service departments of the relevant staff told correspondents: the current battery capacity of the theory driving the design data are generally in the 200 km to 400 km between the maximum speed of 100 to 150 km, but from the user feedback data analysis, the actual situation can only reach about two-thirds of the desired design.

BYD electric cars such as the official data is 2 hours fast charge to charge 57 degrees, can travel 300 kilometers, this theory as the traditional car fuel consumption, the average user in all weather and road conditions can reach 200 km is very substantial.

Shanghai Power Company insiders have said: Shanghai's 825 bus is a super capacitor and battery hybrid "battery - capacitor" type vehicle, fully charged, the maximum driving range of up to 300 km, but because there is consistency of the battery problem, charging is completed, driving range is only 100 kilometers.

Industry experts said that current electric cars are a lot of data laboratory data, if fully charged electric car can run 300 kilometers on the case, according to market electric vehicles to maintain the basic calculation require charging stations at least 25 km to build a. "The current layout of the domestic electric bus station, far from this level, therefore, to fully launch the new energy vehicle market, to improve battery performance and step up power plant layout to be walking on two legs, and even the battery performance issues that the limitations of the market of more. "

According to the Investment Adviser's "new energy vehicles in China in 2008-2010 Industry Analysis and Investment Consulting Report" shows that by 2012, annual production of new energy vehicles will reach 100 million.

At each new energy automotive batteries cost $ 70,000 and power lithium battery cathode material lithium iron phosphate 52 kg, 41 kg anode material, electrolyte 40 kilograms, 100 million hybrid vehicles will drive the 52,000 tons cathode material, 4.1 ten thousand tons anode material, 40,000 tons of electrolyte needs. For domestic battery manufacturers, this will be a total output value of over $ 70 billion big cake.

Oil into clean energy and focus

Invested heavily in the face of the battery automotive industry, new energy law's authority suddenly gave a blow. Energy Law on 13 April members of the drafting of a core group of experts to the outside world, said: Energy is still in draft for consultation and the State Council Legislative Affairs Office of modified fast, then in the second half can be submitted to the State Council executive meeting.

According to him, as reflected China's efforts to address climate change, the original draft in the draft energy law had "priority to the development of renewable energy," the statement. However, as renewable energy development in China, there are still some problems with fossil fuels in China's energy structure, the proportion is still more than 70% in the short term is difficult to change, and later proposed the 'priority' to ' encourage the development of '. Although embody the support of renewable energy, but the meaning is slightly different. "The source said, at the same time, clean coal and other fossil energy sources, efficient, and utilization will be emphasis.

If the new energy law does have such a subtle wording of the correction, many of which will result in massive infrastructure projects on the direction of the transfer.

For the oil clean energy, electric power system is certainly no longer now the warm car battery, because that they have neither the resources nor the network edge. Without competition, Sinopec, PetroChina is waiting for law to walk, focus on developing countries to subsidize, and they slowly develop outlets. This new energy vehicles has evolved a chicken-and-egg story.

As of April 6, Jilin Electric Power Co., Ltd. has been with eight cities (state) signed a strategic cooperation agreement. By 2015, Jilin province will build 160 charging stations. April 1, Hangzhou, Zhejiang Electric Power Company and the Government signed a cooperation framework agreement. This year, the company in Hangzhou, Zhejiang, 6 new charging stations in the province's new 500 charging pile, the current site has been basically completed. 2, Sichuan Power Company, respectively, and Leshan, Yibin, Guang'an city government signed a strategic cooperation framework agreement, specifically the city electric vehicle charging facilities is an important part of the distribution network. Previously, the company has with the Sichuan Chengdu, Nanchong city government signed two cooperation agreements.

If the new energy law to put these people really as a sharp turn, the power system so vigorously advance, how will it end?

New energy investment opportunities in the automotive battery industry

One plan the series of reports emerging industries:

New energy investment opportunities in the automotive battery industry

Industrial policy, fiscal policy support to the industry a tremendous space for development, the whole industry chain are faced with investment opportunities, the battery industry is the core benefit areas.

New energy vehicles for the first time been included in the government work report, a national strategy in China's energy saving strategy was given higher expectations. National Development and Reform Commission, said the end of March, "the new energy vehicle development program" will be introduced. Policy support to the plate with great space for development. Other studies have found that in the new energy automotive industry chain, the battery industry will most benefit.

Emerging industry focus

New energy vehicles as a national strategy for the first time been included in the government work report, will enter a substantive stage of development, a strategic emerging industries in the world spotlight.

Development of new energy vehicles is of great significance, it is a low-carbon economy and the integration of the automotive industry a technological revolution. On the one hand is the inevitable choice for low-carbon economy, the other is China's automobile industry continues to grow the only way. The industry's transformation into practical productive forces, China's economic transformation in the implementation of specific industries, not only to residents of a huge car meet consumer demand, promote economic growth, but also low-carbon economy and emission reduction targets can be achieved at the industry level, but also help enhance our international competitiveness of the automotive industry.

Following the Government's commitment to achieve the 2020 carbon dioxide emissions per unit of GDP in 2005 dropped 40% to 45% target. Automotive emission reduction targets as one of the main, the need for higher emission standards, new energy and automobile industry with the inevitable.

Currently on the market there are two major new energy vehicles. One for hybrid cars, such models have relatively mature, but higher production costs, as long as the relevant government departments to give some financial support, it can be promoted. Another is the hydrogen fuel cell vehicles and electric vehicles, but inadequate urban infrastructure facilities related to the promotion of new energy vehicles need this part of the relevant departmental interaction, in some cities only after a successful pilot implementation.

Beginning in 2009, the state planning industry docking. Published in March last year, "the automobile industry restructuring and revitalization plan" that is planned to 2011 form 50 million new energy automobile production capacity, new energy vehicle sales accounted for 5% of total passenger car sales around. Meanwhile, the National Development and Reform Commission started in May last year, the new energy vehicle battery, capacitor, electric drive motor and accessories industry, intensive research to understand the overall technological level of industry and development status, screening has the core components of the production innovation enterprises, defining policy to support the object.

Last year, Premier Wen Jiabao in Shanghai to study, he put forward to support the development of electric vehicles. , The National Development and Reform Commission automobile team leader Wang Shulin said that the new energy vehicle development plan has been submitted to the State. New energy vehicles in the national leaders of the care and industrial policy support, and gradually into the fast lane.

The key policy support

Foster a new industry in a major R & D, productivity and promote the application into a chain, the state fiscal and financial policies play a key role in supporting and related industries and industry segments and improve the standards are very important.

Premier Wen Jiabao in his government work report, and actively promote the new energy vehicles, "substantial progress" and strive to break new energy vehicles, "key technologies." The number one this year, the CPPCC proposal is to develop low-carbon economy, new energy vehicles as the main object of attention of CPPCC members.

It is reported, the National Development and Reform Commission will announce the end of March, "the new energy vehicle development plan." "Two sessions", the Ministry of Industry and Minister Li said that the new energy automotive R & D investment is relatively large one-time, the price is relatively high, in order to encourage the private purchase, the Ministry of Finance in consultation with the subsidy policy, the maximum amount of subsidy may reach 60,000 yuan . It is predicted that by 2012, domestic Demonstration of new energy vehicles will reach 60,000, the Ministry of Finance will also be special subsidy of up to 20 billion yuan

Countries in the industrial policy to promote the continued implementation of the policy, while this year's number of central enterprises will also start building charging stations, new energy vehicles pilot entered a substantive stage. CITIC Securities, predicted that the new energy vehicle demonstration city expanded from 13 to 20.

The new energy automotive industry during the relevant industry standards and sub-industry standards is essential. Universal Group Chairman Lu Guanqiu proposed the "development of new energy vehicles on the recommendations of the national standard," proposed the establishment of national standards committee of new energy vehicles, well-developed industry standards. Lu Guanqiu key components for the establishment of a unified industry standard system, the development of lithium-ion electric car industry standards, and developed to enhance the standard of the new energy automotive industry standards, to develop common standards with international standards for new energy vehicles. Zeng Qinghong, general manager of Guangzhou Automobile Group made the battery life and charging time constraints of the electric car industry, national standards should be as soon as possible.

Core investment opportunities in the battery industry

New energy automotive industry is facing long-term investment opportunities, the whole industry chain will benefit, the core benefit is part of the battery industry. At the same time, investment value also to the electrical system, vehicle, and fields of upstream resources.

Battery industry is concerned about the hot market, on the new energy vehicles, almost all of the investment and research institutions will focus to this segment of the industry. Car huge amount of battery, an electric car than 4,000 laptop computers, cathode materials for each car average 50 kg, 40 kg anode material, electrolyte 40 kg. 2009 domestic demand of 8,000 tons of electrolyte, only 50% increase in auto demand.

Higher penetration of current lithium batteries, nickel metal hydride batteries are also good prospects for development. Lithium high gross margins, great support of the relevant corporate performance, gross margin was 30 percent positive, negative 20%, 40% of the electrolyte, diaphragm 70%, Lithium hexafluorophosphate 70%.

Biggest names in the domestic photovoltaic thin-film battery prospects retrial

Since the fourth quarter of last year's strong recovery this week in Shanghai at the "Sixth China solar grade silicon and PV Power Conference" has become a successful major photovoltaic manufacturers to get rid of the financial crisis a "celebration party." At the meeting, the domestic solar photovoltaic gurus of the future full of confidence, especially for thin-film battery prospects for a re-evaluation.

Prior to the industry view was that, as polysilicon prices collapsed, thin-film battery competitiveness will decline, and even some scholars believe that the cost of thin-film batteries with silicon no advantage at all, may be between 3 to 5 years in China disappeared. In this regard, a number of photovoltaic industry yesterday to be refuted.

Ministry of Industry and Information Technology Electronics and Information Wang Bo, deputy director, said in a report yesterday, the current domestic companies more than 60 thin-film batteries, although the proportion is still high, but as a representative of the new technology, the energy conversion efficiency is gradually improved, and its production costs are lower, the proportion expected in the future will be increasingly high, and in the future to play its own advantages.

Zhejiang University, Professor Yang Deren also revealed that Japan held the "2010 NEDO Conference", the community also discussed how to thin film batteries to a more efficient and cost-direction and other issues.

Semi china analyst Song in Beijing, said countries are to increase solar energy technology development, and hope our government can be established as soon as China's own Solar Energy Research Institute, and enhancing our thin-film batteries, or other new technology research and development capabilities, accelerating the pace of solar grid parity .

"Although, with the crystalline silicon products, prices, thin film cells differentiated competitive advantage has been weakened, but the company remains devoted to its great energy, and is gradually enhance their competitiveness. The future will show a new look to all walks of life . "Zhejiang Chint Solar Energy Technology Co., Ltd. General Manager YANGLI said.

Baoding Tianwei Ma, general manager of thin-film photovoltaic thin film cells on the same literature, the future development of confidence, "thin-film battery technologies is still in its infancy, much room for technological advances, the cost can fall, we should be emerging products to give sufficient confidence. "

New GM hydrogen fuel cell system will be put into operation in 2015

March 16, General Motors, said GM is currently testing the new hydrogen fuel cell system, and the battery system will be put into operation in 2015.

GM said the new research and development of hydrogen fuel cell system is the size of the Chevrolet Equinox fuel cell vehicle equipped with half the weight of 220 pounds, only one-third of the fuel cell Equinox.

GM spokesman Alan Adler said in an interview, the new hydrogen fuel cells because the volume is small, so it can carry a variety of models, such as cars and crossover vehicles, even in the compact car can carry.

But Alan Adler did not disclose the new hydrogen fuel cell production in 2015, will be used in the Which models.

Currently, GM's Chevrolet Equinox hydrogen fuel cell vehicles are in the testing phase.

Recently, GM's global powertrain chief executive, said Charles Freese, GM will not give up hydrogen car plans.

Compound semiconductor multi-junction solar cells will be mass production

U.S. Weixun joint semiconductor (RFMicroDevices, RFMD) to use the company's 150mm GaAs compound semiconductor production line, trial out of the solar cell. RFMD said it is the conversion efficiency of more than 40% of the "compound semiconductor multi-junction solar cell to achieve commercialization milestone."

"Low-cost, long life, low carbon emission" Silicon Valley stunning revolutionary advent of solid-oxide battery box

Former U.S. Secretary of State George Shultz and Colin Powell, California Governor Arnold Schwarzenegger, eBay president , Google co-founder Larry Page, and Wal-Mart, Coca-Cola, FedEx and other famous enterprises of high-level U.S. ... ... A few days ago, the political and business circles of the biggest names gathered in San Jose, California headquarters, eBay, not the purpose of their visit to participate in celebrity party, but attended the Silicon Valley emerging energy company Bloom Energy has launched a high-profile solid oxide fuel cell cartridges - Bloom Box.

Tight-lipped after many years, Bloom Energy CEO Sridhar finally announced to the world of this $ 400 million, eight-year-old developed a mysterious fuel cell. According to Sridhar introduction, Bloom Box truly low-cost (10 per cent commercial use only), longevity (life up to 10 years), and almost no carbon emissions, is a "change the world" products, there are more than 20 leading U.S. companies to buy and are using this new battery box. Bloom Box there is a great way of attracting U.S. and AFP and other Western media's attention, almost all of the agency in its the first time a report, the famous CBS "60 Minutes" program is also after the conference Dahl had an exclusive interview on the Sri, then known as the "Box" fuel cells what magic? It really would like Sridhar said, enough to change the world?

Solid oxide fuel cell breakthrough

Bloom Box is a new solid oxide fuel cell (SOFC), from the property can be classified as third-generation fuel cell, is stored in a direct fuel and oxidizer in the chemical energy into electrical energy efficiently all solid-state chemical plant.

Compared to the first generation phosphoric acid fuel cell (PAFC) and the second generation of molten carbonate fuel cell (MCFC), solid oxide cells with high efficiency and adaptability to a wide range of multi-fuel gas and other excellent features. However, as with most new energy, the traditional high-cost solid-oxide cells are also facing problems, because such cells in the production process will inevitably have to use platinum and other precious metals, and because the requirements of high temperature operation, solid oxide battery in a sealed and structural problems, such as the interface between electrolyte and electrode chemical diffusion coefficient of thermal expansion, matching between different materials and the stability of the bipolar plate material, there are a lot of technical obstacles, it simply is "not afford" . American manufacturer of UTC Fuel Cells Solid oxide cell research for 30 years, but still at the experimental stage, its technical difficulty can be imagined.

Bloom Box in materials science and manufacturing processes on the homework the article, it completely eliminates the use of precious metals. According to Sridhar said, Bloom Box core material is sand, zirconium oxide and other semiconductor materials, not more expensive cost of copper and other metals, so the cost would be guaranteed. Bloom Box also has a revolutionary on the compatibility of the performance, it can use almost all the hydrocarbon fuels such as ethanol, bio-oil, gas, or gas, or even vodka, but the whole process of producing electricity, but will not burn these materials, Because solid-oxide cells generate electricity through electrochemical reactions. In the use of oil, coal bed methane and other fossil fuels power generation, its carbon emissions of only 40% of conventional thermal power plants, and if the use of non-fossil fuel power generation, it can be zero carbon emission.

"Cheap cheap electricity rather than batteries."

Fuel cell research has been a century of human history, but the earlier products are basically concentrated in the aerospace and automotive industries, in large-scale commercial and residential areas are rarely tried, this is because the high cost of fuel cells, on the other hand because of poor stability of these batteries, and life is very short, Bloom Box is promising a major breakthrough in this field.

Sridhar at the press conference to launch the Bloom Box size refrigerator rather, the power output of 100 kilowatts, costs about $ 700,000, but the service life of 10 years is sufficient to allow users to recover the costs. Currently over 20 companies nationwide to buy this type of Bloom Box, FedEx once bought five, Google has its headquarters in Mountain View, California purchased four, eBay, Coca-Cola and other companies have also become Bloom Box's first customers. This bulky battery pack from the effects point of view is equivalent to an independent power plant, as long as raw materials to independent power, without the grid, there is a great advantage is to avoid power loss during transmission. Given the higher subsidies in California, Bloom Box cost of electricity is only 8 to 10 cents per kWh, lower than the California commercial electricity currently 14 cents per kWh, the average price, doing three to five years of purchase cost recoverable. In addition, Bloom Box is not vibration at work, no sound, but no odor.

So in the U.S. and other world or no subsidies, subsidies for low areas, Bloom Box you can continue to play magic? In fact, the only conference to announce the Bloom Box series products a, Bloom Energy's vision is not limited to these super-rich and powerful company. According to Sridhar said, Bloom Box products array has many branches, from a single bulb for energy to fuel cells for large enterprises to use the 100-kilowatt battery system of everything. As a few years ago from NASA (NASA) to resign entrepreneurial scientist of Indian origin, Sridhar's ultimate goal is to supply the family, he is expected into the home of the Bloom Box was born in the next few years, the price generally $ 3,000, Sridhar this argument is "we provide cheap electricity is not cheap batteries."

Geometry skill to change the world?

Silicon Valley high-tech companies everywhere, "Box" before the introduction of Bloom Energy can only be used to describe the unknown, but now it seems to have become the hottest star of Silicon Valley, "Times", "National Geographic", "Popular Science" , "Business Week", "New York Times" and a number of mainstream media are full of praise for Bloom Box, Schwarzenegger even be defined as "the history of the United States one of the greatest achievements," but like all new technology, like, Bloom Box brings controversy is not small.

"Fortune" magazine confirms Bloom Box of innovation is also questioned. In view of the core technology Sridhar secretive, $ 700,000 in the price situation, difficult for outsiders to judge from a purely technical point of view this battery really solve this problem cost-effective. In this regard, Sridhar explained that the Bloom Box involve trade secrets, and has submitted patent applications, eight years as the company announced new products that do not want it to be a laboratory, but must first prove that it can be spawned an industry. Sridhar broke the news that the first internal version of the Bloom Box 2006 year already there, according to the agreement with the U.S. Department of Energy, which they sent to the University of Tennessee for two years of testing, after starting from July 2008 to the company send a field test of the product. eBay, installed seven months ago, five Bloom Box, now meet the nearly 15% of eBay's electricity needs.

United States, "Market Watch" (Market Watch) have suggested a non-technical problems: The U.S. Government is not a major supporter of fuel cell technology. In the "American Recovery and Reinvestment Act", the fuel cell technology is one of the lowest share of aid, although the overall high-tech batteries and electric vehicles won the $ 2.4 billion in government loans, but so far only from the fuel cell $ 42 million. Overall view, Bloom Box is indeed promising, but needs to be done.

3 Results and discussion

3.1 Maximum electric power production

Select the appropriate external resistance in order to facilitate cell to produce the best output power, the normal operation when the battery voltage platform to change the external resistor (0 to 5000?), Get resistance? Output power and resistance? Voltage (Figure 4). With the external resistance increases, the battery voltage increases, but the growth rate is slowing down; battery power is increased first and then smaller in the 510? near the battery output power (0.077 mW), the output power density of 11.82 mW/m2 this experiment to determine the resistance of the battery is 510 outside?.

3.2 chlorella and its role in the MFC anode power law for the study of Chlorella produced at the anode effect on the production of electricity carried out control experiments. Anodes access Chlorella device I, II do not access, the cathode by adding 50 mmol / L potassium ferricyanide solution [20], external resistance was 510?, experimental results shown in Figure 5. I microbial fuel cell voltage is significantly higher than II. I microbial fuel cell reaction occurs as follows:

I have battery voltage consists of two parts, part of Chlorella photosynthesis photolysis of H2O, the process produced some of the cathode electron and proton transfer to [(2)]; the other is outside the cell metabolism photosynthesis carbohydrates in the process of accumulation outside the cell membrane cytochrome lose electrons to the anode [(3)], electronic and through the external circuit, the protons through the proton exchange membrane to the cathode. chlorella battery without the voltage values from 0.07 V II down to 0.01 ~ 0.02 V, then add in the cathode 50 mmol / L potassium ferricyanide, 0.07 V voltage to rise rapidly around the battery voltage with the potassium ferricyanide solution II the consumption decline, potassium ferricyanide solution can accelerate the electron transfer rate, improve the battery voltage.

To examine the cell suspension on the impact of power output, battery run time, it will replace the battery electrodes is not I access Chlorella electrode, the results shown in Figure 6 experiments show that after replacing the battery voltage to keep the electrode in the background voltage After a period of time has increased, and when re-replacement of the original electrode, the voltage quickly rises to about 0.09 V, which shows the adsorption removal of the battery cells, battery electric performance of a significant decline in production, the replacement anode adsorption Chlorella electrical properties of the battery capacity after recovery can be seen suspended cells contribute to the power output is very small, power output due to adsorption on the electrode on the chlorella, the biofilm formed on the electrode the electrode into the dish to pre-enrichment the electrodes into the room when a very mature biofilm formation when the battery I run stable, the cathode and then adding 50 mmol / L potassium ferricyanide solution, a rapid increase in voltage, which is due to Fe3 + in potassium ferricyanide

Reduction rate faster than the O2 [(4), (5)], can accelerate the electron transfer rate, power output increase the reaction period of time, consume potassium ferricyanide, stabilize the battery voltage drop. This When injected into 50 mmol / L potassium ferricyanide solution, a rapid increase in voltage.

When the battery when I run stable again, the abolition of the light, the voltage has dropped to the background voltage (Figure 7) in the absence of light conditions, photosynthesis of Chlorella can not continue to produce carbohydrates and hydrolysis, only decomposition carbohydrates has been formed, until the complete decomposition of the voltage gradually decreased to the background current, and the experiments show that illumination of photosynthetic microbial fuel cell voltage changes in one of the main factors is the battery I can be stabilized at 0.09 V voltage around the main reason.

Chlorella in MFC 3.3 and its production of cathode power law in order to investigate the chlorella cell voltage cathode to improve the role of preparing two sets of experimental apparatus, numbered III and IV. III cathode battery access a small isolated training ball algae, chlorella cell IV is not access, adding activated sludge and anode are 0.2 mol / L sodium acetate 10 mL, add 510? fixed value resistor before the anode through N2/CO2 adding activated sludge mixture (80 / 20?) divisible medium of oxygen, sealed after inoculation or slowly through the mixture [4], the cathode without ventilation.

Shown in Figure 8, III cathode microbial cells generated by the battery voltage slightly higher than the IV. This is because the battery's cathode III in Chlorella photosynthesis to produce oxygen for microbial cells to provide more adequate electron acceptor, to speed up cathode oxygen reduction rate, accelerate the electron transfer rate, thereby reducing the oxygen in the cathode reaction with H + overpotential, increase the battery output voltage.

Battery III running for some time, microorganisms adsorbed on the electrode gradually formed biofilm, then the voltage stabilized at between 35 ~ 40 mV, but prolonged reaction, sodium acetate consumed, the voltage dropped to the background voltage, and then add the acetic acid sodium, voltage rise rapidly (Figure 8). photosynthetic Chlorella cathode microbial fuel cell adsorption reaction is as follows:

Anode (anaerobic):

Anode inside the activated sludge process of cell metabolism acetate [equation (6)], accumulated outside the cell membrane to the cathode cytochrome lose electrons, e and then through the external circuit to the cathode, the anode chamber generated by H + through the proton exchange membrane to the cathode chamber , dissolved oxygen in the cathode chamber the electron is eventually restored, and then the reaction of water with H + [(9)] at the same time, photosynthesis of Chlorella in the cathode water decomposition [equation (7)], cell metabolism and decomposition of photosynthetic role of carbohydrates produced [equation (8)] will increase the oxygen in the cathode reaction with H + super potential, which led to the battery voltage IV III than a small increase, an increase of only 0.01 V or so.

3.4 the use of photosynthetic micro-battery sewage

Beijing will be taken from the settling tank Gaobeidian sewage treatment plant effluent (COD = 321.2 mg / L) to join the stable operation of the microbial fuel cell anode chamber I, while the treatment of organic waste generation, respectively, after dealing with different time sampling measured COD, the results shown in Figure 9. can be seen by adding organic waste, the microbial cell voltage from 0.09 V I rose to about 0.12 V, stabilized after a period of decline, remained at around 0.1 V, which is due to join in the anode organic waste provides nutrients for the chlorella, the voltage increased rapidly to a peak when the battery is running for some time, the battery voltage is stabilized due to the organic wastewater containing organic nutrients, so the stable voltage value slightly higher than 0.09 V.

Chlorella handle the sewage, the sewage in the 21 d of COD values from 321.2 mg / L reduced to 189.6 mg / L, removal rate of 40% proved, the use of chlorella wastewater treatment can effectively remove waste water organic matter, phosphorus, nitrogen, significantly reducing wastewater COD. So, the use of chlorella to build microbial fuel cell, producing electricity at the same time in the wastewater, while the use of waste water and solar energy into chemical energy to electrical energy is feasible.

4 Conclusion

This work was built using microbial fuel cell chlorella, chlorella examined were added to the anode and cathode and wastewater as substrate cell production of electricity and electrical principles of production, sewage treatment and the use of the battery feasibility study draw the following conclusions:

(1) the use of chlorella is the feasibility of building a microbial fuel cell, this battery can be chemical energy, light energy into electrical energy, while sewage treatment and recycling chlorella, chlorella to reduce production costs for wastewater treatment resources to provide a new way of thinking. battery output power density of 11.82 mV/m2, the COD removal rate of 40%.

(2) The power output depends on the adsorption on the electrode surface of the algae, with the algae suspended in basic solution has nothing to do. Anode and cathode are aerobic running, compared with the MFC has been making simple, easy to operate and expand the practical application of the field.

Hybrid vehicles for our country provides a good opportunity to catch up

It can be expected in the battery energy density and efficiency of investment and improvement work will continue, HEV / EV market will continue to grow worldwide

pure electric vehicles as a "zero emission" technology, in order to catch up with foreign technology in China provides a good platform

BrianBlack: the promotion of hybrid electric vehicle (HEV) and electric vehicles (EV) in the development of a number of factors, worries about climate change is just one of the other contributing factor is to improve the energy efficiency and through the use of alternative energy sources to improve air quality and reduce emissions, the third driver is that people want the relative supply of fuel energy is changed to more easily switch between.

Hybrid vehicles and electric vehicles are still at an early stage of development, but also because of the need in the car driving distance, cost and user-friendliness (such as recharge methods and time) trade-off between the path of development so they may be different. However, it can be expected that, in the battery energy density and efficiency of investment and improvement work will continue, HEV / EV market will continue to grow worldwide.

Yin Shusheng: 2010 development of hybrid vehicle market will show rapid growth, HEV / EV market will continue to grow worldwide. Official cars and private cars should be the mainstream for the development of pure electric vehicles, battery to supply electric vehicles in the form of rental customers, to reduce car costs, reduce the use and maintenance costs.

The market will be plug-in hybrid buses in the mainstream, that is, power generation systems with smaller and less efficient lithium-ion battery pack provides power for the vehicle, so the overall energy supply system can further reduce the cost of hybrid systems, size and weight. In addition to hybrid cars, another option is the oil and gas hybrid is the high pressure gas from the fuel generators and power transmission work together to power the vehicle.

Wang Liang: pure electric vehicles as a "zero emission" technology, in order to catch up with foreign technology in China provides a good platform to start the same time period at home and abroad, in some ways has a leading position in China, and has good market prospects. With the current situation, it is foreseeable, the new energy vehicles in particular, is a pure electric vehicle technology will gradually mature in China, the market will gradually improve and development. Only full advantage of the long-term battery research in the outcome, especially in the key power batteries and battery technology greatly exceeded it possible to better establish the advantage, in electric vehicle technology has made great leaps.

Battery management unit to enhance the efficiency of battery

Battery Meter management is the amount of battery charge and discharge the statistical work and data available to the vehicle management system; charge management unit for the battery charge and discharge the functions of the implementation of monitoring

secondary battery technology, especially high-power battery technology is still restricted the development of new energy vehicles

BrianBlack: HEV and EV systems although there are significant differences, but for accurate and reliable operation of energy measurement is a common basic requirements. Linear IC products manufactured in these two applications have been given to use.

Liu Peng: HEV, especially on the EV, the maximum utilization of stored energy is the key to the increase in vehicle driving range. Therefore, the active cell balancing technology developed rapidly. Battery match the implementation, not the high-power battery discharge to the lowest power consumption, but high-capacity battery energy transfer to low-power battery. This is patented technology by Texas Instruments PowerPump achieved, it is the basic DC / DC converters use a small set of inductors and transistors, to obtain about 85% efficiency. However, lithium-ion batteries also require close monitoring over voltage, under voltage and temperature levels to avoid possible fire or explosion. TI provides a highly integrated battery monitoring and balanced solution.

Yin Shusheng: measurement of management is a battery charge and discharge the battery statistical work and data available to the vehicle management system; charge management unit for the battery charge and discharge the functions of the implementation of monitoring of each battery unit has detected a battery temperature , voltage, current, balanced self-discharge voltage.

Lead-acid batteries have great vitality and look forward to days with greater development

2011-06-13T11:16:00.000+08:00

Lead-acid batteries have great vitality and look forward to days with greater development

Battery base, and with the days to the Group Chairman of the Board of China's Zhang Tian any prospects for the development of new energy battery made the exchange and discussion, to group vice president Yang Yuanling day, deputy chief engineer Renan Fu, Chief Investment Officer Wang Zhikun and well-known Chinese experts in electrochemistry Dr. Cao Gaoping join the discussion. Academician Yang believes that from the state, national interests and economic development to take into account the overall development of China's new energy battery. Good prospects for the future development of lithium batteries, but the main problem is that the battery safety and compliance rate, lead-acid batteries in the field of electric vehicles and energy storage battery accomplish much, the key is to continue to make technological progress and environmental protection .

Lead-acid batteries have great vitality, there will be new as

Academician Yang introduced, lead-acid batteries through 150 years without failure, in the nickel - cadmium batteries, nickel - hydride batteries, lithium ion batteries, new battery has been launched in several decades, still firmly occupy the majority of market share; China annual output of nearly 20 million electric bicycles, most equipped with lead-acid batteries; the world's various locomotive, every car is a piece of lead-acid batteries, they are not. In addition to its technology is mature, inexpensive cell cheap, safe outstanding advantages of the traditional, with its competition in recent years in the development of many new technologies are closely related, such as three-dimensional and two-dimensional structure of the electrode and the whole sealed, tubular, Horizontal and other new structures; use the new lead alloy electrode, can promote the gradual increase in specific energy and cycle life of up to 4500 times. Lead-acid "super battery" is also one of them the latest technology. Therefore, lead-acid batteries are not outdated, lead-acid battery technology.

What is a lead-acid "super battery"? The so-called lead-acid "super batteries", UltraBattery, is the super capacitor in parallel with the use of lead-acid batteries (can be called "external and"), evolution is "in and" is the double-layer capacitors with high specific power, long life the advantages of integration into the lead-acid batteries, while maintaining the "outside and" increase the power, extend battery life while the merits, but also simplify the circuit and improve the specific energy, and reduce the total cost. It has been great development in China's electric bicycles and electric vehicles is starting, will have a huge economic and social benefits. Lead-acid "super cell" There are two key technologies, one for high-performance capacitance in sulfuric acid electrolyte carbon, and second capacitor anode of carbon and lead compound.

In a combination of new technology, lead-acid battery energy density can be increased to 60-80wh/kg, power can be increased to 600-700w, which is close to lithium battery technology indicators.

863 should support the development of lead-acid battery technology

Recently, the U.S. President Barack Obama announced 2.4 billion dollars funding 48 projects to support the development of the United States, "the next generation of battery and electric car" production, including lead-acid batteries, were arranged $ 34,300,000 and $ 32,500,000 to support the two companies Lead the development of "super cells" project. Remarkably, the plan does not mention hydrogen batteries and fuel cells.

Academician Yu-Sheng Yang called it "a monk from the Scriptures", to move China's "Buddha", is no longer biased against lead-acid batteries should be solid support for a lead-acid batteries. Academician Yang suggested that China's 863 plan should be clear support for lead-acid "super batteries", not hesitation. To this end, he suggested the Government to produce 45 million yuan (equivalent to U.S. 1 / 10), support the 2,3-producing - research portfolio, coupled with 1:1 matching funds of enterprises, with two years to develop lead-acid "Super Battery" and capacitance of carbon, and formed a certain scale of production capacity. This is to address the financial crisis, the best one of the measures to stimulate domestic demand.

Lithium is the future direction of development, but the technology still needs to be improved

Academician Yang that lithium is a good direction, but we must first solve the problem of security and compliance rates.

The safety of lithium has been concern for everyone. 2009 cell phone lithium battery exploded in China, 7, 3 people died, technically speaking, mobile phone lithium battery is relatively simple, with no serial, parallel problems. It is understood that the energy of lithium is probably the phone 2wh, according to international statistics, one ten-millionth the probability of an explosion, but a bus is probably the energy of lithium batteries 20 million wh, if you press the number of hours and mobile phone Li-watt battery, the probability of explosion may be one per cent, which can not be ignored. Lithium battery industry is to really solve the security problem, otherwise the consequences will be unimaginable. In the end is pretty important, or important to safety, industry professionals should pay attention.

The second problem is the passing rate of lithium batteries. In addition to large-capacity lithium-ion battery technology to enhance, but also further enhance the rate of quality.

The most energy saving electric car

Bottleneck in the development of electric vehicles is the concept, rather than simply technology. In various types of electric vehicles, the biggest advantage of pure electric vehicles: one without oil, 1 million electric cars per day to replace 1 million tons of gasoline; Second, pollution-free; Third, all costs (purchase price + energy prices ) may be lower than fuel vehicles; Fourth, simple, non-oil and water, use, and easy maintenance; Fifth, the battery can be used at night cheap "Valley Electric" and the existing power line charging, not only to promote the "Valley Electric" (mainly nuclear power and wind power), for the grid "distributed peaking", but also save a lot of funding for building energy storage power station.

Leapfrog China should give priority to the development of a single charge can travel 150-200 kilometers of pure electric vehicles.

In addition, the used battery electric vehicles have a variety of development, all kinds of batteries to be "beyond the exhibition and fair competition."

Lead-acid storage batteries in the field of new energy scale has an advantage in competition

On China's new energy development, Academician Yang pointed out that the field of lead-acid battery energy storage in the size of the competition advantage. In the field of new energy storage batteries, the industry has completed a long cycle life for lead-acid battery power storage system test. The system is connected with the overall power supply system, the peaking operation. Test the power storage system, three units were the maximum power of 100kW, 100kW, 400kW, continuous operation of the two and a half, not a battery voltage drop, the voltage difference increases and other issues, the system runs well. Identified lead-acid battery power storage system is practical.

Meanwhile, the development of new energy storage battery cost and life must be considered, lead-acid battery performance and stability, and cheaper prices. Chemistry Institute of Chemical Defense military power of China Research and Development Center has ten years of military batteries, the battery needs of the accumulation of proof, the overall research, technology development experience, particularly concerned about the development of large-scale energy storage battery technology, especially the recommended lead-acid battery The application in this field.

Lead-acid battery industry to focus on pollution prevention and control of lead

When it comes to lead-acid batteries that people often will say, there are environmental problems of lead. In fact lead-acid battery is the highest rate of all varieties of batteries, and lead production process of large enterprises has also been strictly controlled. To effectively solve the problem of lead ore mining and smelting of lead battery recycling waste, acid pollution; as long as serious and responsible step up environmental protection departments, enterprises attach importance to the implementation of environmental protection measures, the problem is not difficult to resolve.

Current lead battery industry should strive to achieve from lead mining, battery production, recycling of old batteries closed operation, this can minimize lead contamination. Why did not pollute the environment of nuclear power concern, because the raw materials of nuclear power to the recovery of uranium from mining, the whole process of environmental protection have done well. Lead-acid battery industry chain can learn from the experience of nuclear power production.

Another new lead-acid "super cell" within the existing lead-acid battery much less than, longer life but also reduce the workload of regeneration, which are of direct benefit to reduce lead contamination.

Lead-acid battery production equipment to achieve domestic

Finally, the Academician Yang comes to lead-acid batteries made equipment problems. He said that now the new lead-acid batteries (such as tubular cells) and the old equipment, a lot of battery recycling business or the use of imported equipment. Expensive imported equipment, prevented large-scale application. Chinese battery company in the import of equipment, be sure to consider the localization of the equipment as soon as possible. Imports of equipment at home is a good opportunity, but also to promote technical progress in China battery industry opportunities. Equipment prices down, companies can use the advanced equipment does not produce pollution. Lead-acid battery industry in China who want to work together, from mining to the old battery recycling throughout the process, as soon as there are plans to promote the equipment in China.

DC switching power supply system and the machine

This article describes the high-frequency switching DC power supply system and machine application experience and experience. As I am only familiar with Eaton Shiweiteke power so some of the views and opinions have some limitations, please understand.

Continuous high reliability of communication system requirements are obvious, but communication with the power of energy suppliers as a system than to a human heart is most fitting that. Complex network environments such as various non-standard electrical equipment operating over-voltage surges caused by lightning or power reliability is a major killer. So increasing the reliability of communication power and when the emergent solution? Some people think of DC and the machine program to solve, I think reliability will be increased exponentially in the 0.1 ~ 2. Programs poor choice would fall between 0.1 to 1, select the appropriate program will fall between 1 and 2. First of all I want to thank our Shiweiteke power has selected users the confidence of our products, I think the fact Rectifier N +1 redundant reliability has more than enough, and would like to thank those who are prepared to use our product users, you choose a company with 15 years of manufacturing experience communication power of international big companies, so I recommend you just set Shiweiteke power of the "a" sufficient power (in this set is a monitor.)

Strongly recommend the best solution:

DC power supply and two direct drive capacity is also no limit to work with only one monitor controlled rectifier to work as a backup to another monitor. Monitor can be manually backup or automatic backup, as Shiweiteke monitor power products have a normal monitor relay instructions, instructions manual backup when failure and automatic backup monitor is also more convenient to implement. The key point of this program is that the exchange of the two systems must be independent loop-powered circuit. Lead to the collapse of the entire system as the primary factor is the exchange of power in the mine or operation over voltage surges. Using two independent AC power supply circuit can greatly reduce the probability of the collapse of the entire system. Can be solved and the machine after the rectifier DC current sharing, the battery charge current limit function. Drawback is that two sets of power supply to be used for Shiweiteke (SM40 or more monitors).

The second program, DC, and hot backup machine monitor

Basically, with the first program, but must monitor SC200, SC200 using monitor standby features, a higher cost of the use of SC200, but it can be called perfect, and advanced machine. Line of Control between the two systems less and neat.

The third program, the diode and the machine

Diode and the machine is a traditional and more reliable programs, old and new sets of system is not restricted. Disadvantages are:

1. Diode voltage drop is high energy consumption

2. Capacity is limited, our highest achieved 400A.

Principle see below:

The fourth program, double the electricity sector and the local system

Double for power and computer system, usually two systems independent of each other. Rectifier only when a system in which the two systems have failed and there is pressure of about 1V when the two machines to enter and drive mode. In manual operation requires special care, to prevent interaction between the battery charge. And the machine used only as emergency and long-term use of the system are to be considered current, the battery charge current limit.

(Note: only one of a battery or a battery power supply situation has been used before-break switch, to ensure uninterrupted power in the switching load.)

Principle see below:

Fifth programs for the forces of two-and machine system

This program has solved the battery charge current limit function, no batteries on the charging issue. But the only two systems are not resolved flow problem. Note that the two systems must be identical, which applications have some limitations.

Principle see below:

Conclusion

Has advantages and disadvantages and limitations of each program, some programs are Shiweiteke only two systems to apply the product, so users can mix and avoid weaknesses according to actual needs. DC and the machine control program is more complex if used improperly would be counterproductive and will not improve the reliability of the system several times, but I think the more important of the two-machine system and the application of principles are:

1. Input circuit must select two completely different and independent circuits, the independent anti-surge, the better is an independent low-voltage transformer;

2. Control circuit is simple, such as the third option is relatively simple;

3. Considered as close to the load cell design, secure the load;

4. The application for the power sector, due to its power grid and the application environment is better than the specification, N +1 redundant rectifier reliability has more than enough. This is in the power sector for many years running the rectifier modules in the net sum up the resulting rework.

Feast of listed companies to share power lithium battery

2011-06-07T11:05:00.000+08:00

Feast of listed companies to share power lithium battery

Shanghai Automotive hand the United States investment in A123 lithium batteries, lithium iron phosphate Huafang Textile battery development, Foton Motor and Beijing University to establish a new energy battery first ... ... For a time the company listed company involved in wind and water power lithium battery.

Global automotive lithium battery market will show explosive growth, is one of many listed companies competing to snatch the main incentive. It is predicted that by 2014, cars will use lithium batteries the size of the market soared 24.8 billion, an increase of 214 times more than in 2008. Faced with such a feast, to seize investment opportunities as consensus: car companies have to extend the industrial chain to the power battery, battery manufacturers in the reverse direction for strategic cooperation with vehicle manufacturers, and new enterprises also want to get involved in gluttonous feast of lithium batteries Cup points for the U.S. joint venture to share.

Constraints and gradually break the ice

Emissions and oil resources in response to the dual pressures of increasingly scarce in most countries the development of new energy vehicles will be deemed to revive its auto industry and the most important means of energy saving, and reduction in the most stressful and the United States for promoting standard-bearer of new energy vehicle development. Recently, the United States issued the "Joint Statement", said the two sides will launch in the U.S. electric car initiative, the two countries in the next few years, several million electric cars in use.

U.S. Highway Administration optimistic forecast, by 2015, the U.S. auto market, about 20% of the number of cars, hybrid cars, the market size of up to nearly 300 million. The current U.S. market share of hybrid cars is only 3%. It also predicts that by 2020, half of the global automotive market will have a new car with different levels of sales of hybrid technology.

In China, published in March this year, "the automobile industry restructuring and revitalization plan" in the development of new energy vehicles has also developed a general goal - the next three years, China will form a 500,000-in hybrid electric charge and the common type of hybrid new energy automobile production capacity. By 2012, the new production car will have 10% energy saving and new energy vehicles, new energy vehicles are expected to reach 500 billion yuan output value.

Faced with such a tempting cake, the domestic automobile enterprises have place in them, in order to stay ahead. Compared with the conventional vehicles, new energy technology gap with foreign cars do not, there is the possibility of overtaking corners, more implications for the domestic automobile enterprises to increase investment in new energy vehicles optimism.

Such as Shanghai Automotive, according to the company plan, in 2010, saving 20% of consolidated Roewe 750 in the mixed hybrid cars will be mass market; 2011, Shanghai GM will launch with the U.S. General synchronized VOLT electric car; 2012, fuel-efficient more than 50% of the Roewe 550 plug-in cars will be available in volume strong mixing; the same year, SAIC's own brand of pure electric cars to market have truly zero emissions.

It is worth mentioning that, on December 6 Changan Benben MINI success of pure electric vehicles off the assembly line, which is China's first pure electric vehicles. Zhi Xiang, oil and electricity coupled with the weak degree of hybrid cars, Zhixiang gasoline-electric hybrid cars with moderate, Zhixiang Plug-in hybrid electric road vehicles Yue Xiang, Changan Automobile product line of new energy vehicles gradually improved. According to the plan, Changan Automobile will adhere to the integration of a variety of new energy technology development approach, the early days of hybrid and gas vehicles, pure electric vehicles as the focus, the gradual development of fuel cell vehicles, hydrogen internal combustion engine vehicle.

In addition, Brilliance Auto, Geely, Dongfeng and other new energy vehicles have launched their new energy vehicles. But now, most government agencies and institutions only for the customers, not sell to individual consumers. Such as the domestic leader in new energy vehicles BYD, though already introduced three electric vehicles, which go to the end of the market in October this year F3DM planned sales to individual consumers, but the conditions are not ripe, still not into the personal terminal market.

Analysts pointed out that factors in addition to their own electric vehicles, the current constraints on their main external factors to promote the convenience of charging and high acquisition costs, but these two constraints are expected to break the ice.

Construction of the charging station can not do without the support grid. Related to the national grid to receive the China Securities newspaper interview, admitted that market space immeasurable electric cars, the company is willing to build. In the past 2 years, there were 10 provincial-level company research and pilot work, the company also conducted a number of large car prices and research cooperation, made a lot of data is now in full swing in preparation for the construction of the charging station. It is noteworthy that the three major oil companies have shown great enthusiasm, such as CNOOC are now in main building of electric cars and charging network.

The other constraints - high purchase price of electric cars, analysts pointed out that to solve this problem, in addition to their own car prices need to reduce costs, but also to reduce the need for government subsidies. At present, most countries have subsidies for new energy vehicles, such as the UK available to buy PHEV and EV 2000-5000 pounds reward, the Japanese electric, natural gas and other clean energy vehicles, 50% tax cut. To encourage the development of new energy vehicles, China's financial subsidy policy has also been introduced, such as fuel-efficient hybrid vehicle in accordance with the standard rate of subsidy is divided into five files, the maximum subsidies for 50,000 yuan per vehicle; pure electric vehicles can be subsidized 60000 yuan. However, subsidies have not yet implemented, the car prices of new energy vehicles can only be married purdah. However, this may not wait too long to make car prices, the state key projects of new energy vehicles, team leader Wang Binggang Project Management and Consulting, said the subsidy for buses and other policies have been implemented, the subsidy policy is estimated that consumers will soon introduced.

Growth in the market will break out

Analysts pointed out that with the convenience of subsidies and charging solution, the new energy vehicle market will see explosive growth, and as the scale of new energy vehicles, the rapid expansion of the power battery, motor, electric control, etc. will significantly increase demand This is expected to become the next 10 years the core drivers of industry growth. Among these, the performance of battery development of new energy vehicles plays a vital role. Endurance, consistency, security, and other indicators determine the future of new energy vehicles, the pursuit of higher specific energy than the power, self-discharge, long life and safety of a good battery, to become an important issue of new energy vehicles.

Current hybrid cars use nickel-metal hydride battery technology, nickel-metal hydride batteries, but some of the technical properties such as energy density, charge and discharge speed is close to theoretical limits. The lithium battery has energy density, high-capacity, no memory, etc., by various car manufacturers and battery manufacturers unanimously approved, is currently the focus of national research and development of lithium-ion batteries.

According to the different cathode materials, lithium batteries are lithium cobalt oxide, lithium manganese oxide, lithium iron phosphate ternary materials, and four. SW reported that comparison, lithium cobalt oxide biggest problem is poor security (150 degree high temperature explosive), high cost and short life cycle; the safety of lithium a lot better than lithium cobalt oxide, but the high temperature environment The cycle life is even worse (500 times). Lithium iron phosphate because of the high discharge power, low cost (about 18 to 30 yuan / ton), fast charging and long cycle life (over 1000), in the high temperature stability under high heat (temperature above 300 degrees only security risks), has a good safety performance, which is the best vehicle to use lithium cathode material. At present, China's car prices electric car models introduced, the power batteries are lithium batteries, Chery, BYD are using lithium iron phosphate.

Japanese professional market research agency data shows that the market will show a battery explosive growth. Fuji Institute of Economics and Statistics, the environmentally friendly cars in the world are sought after, popular hybrid and electric cars, the next few years, automotive battery market will expand rapidly. 2009 is expected to ship cars with lithium batteries will amount to 10.4 billion yen in 2008, based on the double to 250 billion yen, while in 2014, the market will rapidly expand the size to 2.25 trillion yen ( about 24.8 billion U.S. dollars), is about 215 times in 2008.

SW's report also pointed out that China's future power battery market space will show up ten times: in 2012 one million new energy vehicles, if 70% of nickel-hydrogen batteries, price 25000 yuan / sets, 30% lithium , price 5 yuan / sets, nickel-hydrogen batteries in 2012 will reach 17.5 billion market capacity, lithium battery market will reach 150 billion global market scale will reach several hundred billion dollars.

Gold rush of listed companies

Faced with such a large cake motive power battery market, listed companies have invested in the United States share a view and cup, and a vehicle plant in car prices has become an important driving force.

Started the car battery instead of BYD Li-ion battery market in the power of natural flourish. August of this year, BYD electric vehicle battery production base in Huizhou, Guangdong completed its BYD electric cars charged with the core technology - lithium battery production tasks, which can be mass production of lithium batteries.

Coincidentally, for the access to technology leadership, a stable supply of battery power system, claim the credit in the new energy bus Fukuda car, was also 10 at the end with the famous Beijing University Li-ion battery manufacturer first technology industry set up the Beijing Automobile Investment Co., Ltd. of new energy investment Battery Technology Co., Ltd. invested 10 million yuan Foton, accounting for 10% of registered capital.

More noteworthy is that, 12 17, Shanghai Automotive and master the core technology of lithium iron phosphate A123 Systems, the U.S. announced they would set up its stake by 51:49 the new battery power system Jie Shanghai Co., Ltd. joint development, production and sales of vehicle battery power system, in order to occupy the leading position in the market. The move also marks a "thunder and rain" into the domestic large-scale models of new energy vehicles take solid steps.

Extended to the lithium battery in the vehicle factory, while lithium battery manufacturers and automobile companies are also actively cooperate. CITIC Guoan and Toyota to lithium carbonate and lithium salts series of downstream products, especially the application of new energy cooperation signed a "letter of intent." CITIC Guoan designated Japan as the exclusive agent in Japan and the Japanese side not less than a certain amount per year of lithium carbonate products. Thereafter, on October 20, Fosugufen to increase in the lithium-ion battery separator market position and level of work BYD has decided to stabilize the market demand and broad market prospects, Foshan Jin Hui Hi-tech company capital increase to the expansion of lithium-ion battery divide the project, thereby enhancing the company's overall competitiveness.

In addition, Jiangsu Cathay Pacific, China Baoan gold and a number of listed companies are lithium batteries. Overall, Shanshangufen has formed a relatively complete industrial chain, the company has grown from a single lithium battery anode materials started, have established a lithium battery cathode material, electrolyte lithium-ion battery materials, such as a complete production line, has become the largest Lithium-ion battery materials supplier.

New energy investment opportunities in the battery industry chain and Analysis

I. Introduction

With Buffett's stake in BYD, Wang became the latest of the richest man in China. The concept of new energy battery not only set off a round in the capital market turmoil, but also the hearts of ordinary people to root implant.

However, as the sensitivity of the industry's most venture capital in new investment in energy battery industry has become very conservative and lag, so far in domestic investment in the field of new energy battery case and the amount of investment is extremely limited. Energy field to help new investors to better grasp the overall development of new energy battery industry, and tap the potential investment opportunities, and Qing dynasties Group launched special "new energy investment opportunities in the battery industry chain and Analysis" report.

Second, principles and characteristics of lithium iron phosphate

1, lithium iron phosphate structure and working principle

Batteries generally include: cathode, anode, electrolyte, separator, cathode lead, negative lead, the center terminal, insulation materials, valves, seals, PTC (positive temperature control terminal), the battery shell and so on. Which cathode material, anode material, electrolyte and the different membrane processes, or different, battery performance and price have a decisive impact.

Commonly referred to as lithium batteries, based on a variety of materials containing lithium battery cathode material, the current market lithium-ion battery cathode material of lithium cobalt oxide is mainly (LiCoO2), lithium manganese oxide (LiMn2O4), plus a few use Lithium Nickel (LiNiO2) and binary / ternary polymer as cathode material for lithium ion batteries. Lithium iron phosphate is lithium iron phosphate (LiFePO4, referred to as LFP) battery cathode material for lithium-ion battery, its internal structure as shown in Figure: the left is the structure of olivine LiFePO4 as battery anode, the cathode foil and connection, in the middle of the polymer membrane, which separates the positive and negative, but the lithium ion Li + can not pass the electronic e-right is made from carbon (graphite) to form a battery anode, the copper foil and the negative battery connection . Between the top and bottom of the battery cell electrolyte, the battery from the metal shell, aluminum-plastic composite film or plastic containers sealed package.

　　LiFePO4 battery works: battery charging, the cathode material of lithium ion de-out, through the electrolyte through the diaphragm into the cathode material; battery discharge when the anode in lithium-ion and from off them, through the electrolyte, Back to the cathode through the membrane material. (Note: The lithium-ion battery is lithium ion charging and discharging due to return migration and named the time, so the lithium ion battery, also known as "rocking chair battery")

2, the performance of lithium iron phosphate and Features

2.1 The advantages of lithium iron phosphate

First, the long life: long life cycle life of lead-acid battery is about 300 times, 500 times the maximum will, and lithium iron phosphate batteries at room temperature, 1C charge and discharge cycle 2000 times, the capacity retention rate of 80%; is lead acid battery 5 times, 4 times the nickel-metal hydride batteries, lithium cobalt oxide batteries is 4 times that of lithium manganese battery 4-5 times.

Second, safe: The combination of phosphate bond strength than the traditional structure of transition metal oxide chemical bond strength, so the structure is more stable, and not release oxygen. Lithium iron phosphate stability at high temperatures up to 400 or more, to ensure that the battery inside the high security; will not overcharge, overheating, short circuit, the impact on explosion or combustion.

Third, environmental protection and does not require rare metals: lithium iron phosphate does not contain any (other than lithium), or heavy metals, non-toxic (SGS certification through), no pollution, meeting European RoHS requirements for environmental protection battery.

Fourth, the charge speed, low self-discharge, no memory effect: Lithium iron phosphate 2C rapid high current charge and discharge, under the dedicated charger, 2C can be made within 30 minutes of charging the battery is fully 95% of the starting current of up to 2C , and lead-acid batteries are no such properties.

Five, small, light weight: product design can be lightweight, volume-capacity lead-acid battery is the same as the 2 / 3, are more compact nickel-metal hydride battery; weight capacity of lead-acid battery is the same as 1 / 3, Ni-MH battery 2 / 3;

Sixth, the battery cell voltage high discharge platform stability: for the 3.2V, low series, high reliability battery; battery high reliability for high current charging and discharging of high-power high-rate discharge characteristics: 10C charge-discharge efficiency of 96 %, and capacity retention rate of 90% or more, can be realized 10C discharge;

To sum up, compared to conventional lithium iron phosphate batteries and other lithium battery, with its own distinct advantages, Table 1 and Table 2, and its performance compared conventional batteries and lithium batteries

Can be seen in comparison with conventional batteries, lithium iron phosphate is only at a certain disadvantage in terms of price, other indicators clearly an advantage. But if we consider the battery life, the price of lithium iron phosphate is the lowest.

Lithium iron phosphate in addition to tap density, g capacity slightly less than two indicators, other indicators account for a great advantage, especially in the cycle performance, environmental protection, safety, cost of raw materials and application areas with.

2.2 The disadvantage of lithium iron phosphate

1, the conductivity is poor, slow lithium ion diffusion. Charge or discharge, the actual specific capacity is low, this problem is restricting the development of lithium iron phosphate industry is a difficult point. Lithium iron phosphate is not the reason why so late a wide range of applications, this is a major problem.

2, the tap density is low. Generally only reached 0.8-1.3, low tap density can be said that the great disadvantage of lithium iron phosphate, which is determined by its small battery such as cell phone batteries, no advantage, so its use subject to a certain extent. Even if it's low cost, good safety performance, good stability, high number of cycles, but if the volume is too large, they can only replace a small amount of lithium cobalt oxide. However, this shortcoming is not prominent in the power batteries. Therefore, lithium iron phosphate is mainly used to produce power battery.

3, the consistency problem is serious. Lithium iron phosphate monomer more than 2000 times the current life, but produced poor consistency of the battery, thereby affecting the battery pack performance and overall life expectancy, so the car used in power there is a certain obstacle.

4, poor low temperature performance of lithium iron phosphate. Lithium iron phosphate material to the inherent characteristics, to determine their inferior low temperature performance of lithium manganese oxide cathode materials, and other. Under normal circumstances, the batteries alone, and its capacity at 0 to maintain rate of about 60 ~ 70%, -10 when 40 ~ 55%, -20 20 ~ 40% of the time. This low temperature performance is clearly the use of power supply can not meet the requirements.

5, the manufacturing costs are high. Lithium iron phosphate has the safety, environmental protection, the number of cycles is unquestionable advantages, but the current production costs relative to lead-acid batteries, lithium manganese oxide is higher, mainly due to: 1) physical properties and other lithium battery materials difference between the larger, and its small particle size, tap density, surface area, good processing properties of materials, coating is low, resulting in increased cost of the battery; 2), lithium iron phosphate is only 3.2V, the low than the other lithium about 20%, single cell to multi-use 20%, causing the battery to form part of the increase more.

As technology advances, lithium iron phosphate material of these drawbacks are gradually being resolved, the price has gradually improved, gradually expanding the scope of application, we believe, lithium iron phosphate battery technology has entered a stage of rapid development, is to drive the entire the cultivation of industrial imports from the market entered a period of rapid growth stage.

Third, lithium iron phosphate chain analysis

3.1 The iron phosphate lithium battery industry chain structure

Table 3 illustrates the detailed iron phosphate lithium battery industry chain and the various aspects of the situation on behalf of manufacturers profit margins

3.2 The lithium iron phosphate material

Raw materials, lithium iron phosphate industry is resource industries, the basic lithium resources around the world have been for the major share of the company enclosure, we believe that lithium resources industries in the venture capital has lost the value of strategic entry. Phosphorus compounds belong to the traditional chemical consumables, has a very mature vendor. In contrast, high- quality source of iron compounds, no absolute advantage in the domestic suppliers, there are some investment opportunities, investors can focus on the Shenzhen Tian Shuo Technology, Hefei Ya'alon and other leading companies in this field.

3.3 Information and Statistics National positive charge

At present lithium iron phosphate material internationally renowned manufacturers mainly the United States A123, Phostech Canada and the United States Valence. These companies have developed a very mature production technology, with the largest production capacity of 5,000 tons / year. Chinese enterprises have been launched since 2001 to develop lithium iron phosphate material, after 6 years, Beijing University in 2007, first broke through the end of lithium iron phosphate technology from the laboratory to pilot production of a series of technical and engineering technology issues, and in improving related process, making the safety of lithium iron phosphate has been greater degree of improvement and assurance, and laid a lithium iron phosphate product series and the basis for industrial scale. Overall, domestic R & D of lithium iron phosphate level and degree of industrialization and international basic synchronization. In terms of production material suppliers in China with foreign manufacturers about the price is lower than abroad, but slightly inferior material processing performance and stability. At this stage there are about 50 more than the battery materials manufacturers, which is just really into industrial mass production in Tianjin Strand, North first, Suzhou is more than ten permanent home. Although the supply capacity of the enterprise truly one of the few, but that the Chinese enterprises to seize opportunities for development of lithium batteries, so that China's lithium battery industry in the forefront of the world. Table 4 lists in detail the top 10 domestic enterprises and their development of LFP materials:

Can be seen that all domestic manufacturers of lithium iron phosphate material are advantages and disadvantages of products, not a factory absolute advantage in technology, manufacturers can not also a large-scale production.

3.4 The situation of negative electrode materials manufacturers

Anode materials, the average gross margin at about 20-30%, and belongs to the new energy battery low margin areas of the industry, this technology is relatively mature, and this area, supply manufacturers are more relevant. There are two vendors in this area of concern: Shenzhen Bei Terui New Energy Material Co., Ltd. and Shanghai Shanshan Tech Co., Ltd..

Shenzhen Bei Terui the development of New Energy Material Co., Ltd. "high energy density lithium-ion battery anode material (BTR-158-B)" New products have won the title of key new products in Guangdong Province. According to the Japanese lithium battery-related consulting company IIT Research Report, 2008, Bei Terui negative electrode materials industry in the global market share of 11%, ranking third behind Japan's Hitachi Chemical (Hitachi Chemical) and Seiko carbon (Nippon Carbon), the market share in China, ranked first, the market supply in 2008 reached 2,360 tons, the main customers for the power of God, ATL, BAK, and A123.

Shanghai Shanshan Shanshan Group Co., Ltd. is a joint venture with Ningbo Shanshan Co., Ltd. established. Carbon is the main lithium-ion battery anode material --- mesophase carbon microbeads (the CMS), modified artificial graphite powder (referred to as CMP) production and sales, an annual capacity of 1,200 tons. According to the Japanese consulting firm IIT report, Shanghai Shanshan anode materials in 2008 amounted to 1,650 tons actual supply, the market share ranked No. 6, the main customers for BYD, the power of God, ATL, and BAK.

3.5 diaphragm case manufacturers

Membrane is high technology, greater investment in industry, at this stage not yet formed a national breakthrough in membrane technology, mainly imports mainly high-end, resulting in membrane expensive, but enterprises can enjoy higher margins. Areas in the membrane of domestic technology accumulation and size of some enterprises in Shenzhen High-Tech star source material and Goldfield.

3.7 The situation of batteries manufacturers

Batteries due to production process and production technology is relatively mature and stable cathode material in the supply situation, most of the domestic lithium-ion battery manufacturers are able to produce lithium iron phosphate batteries, but battery manufacturing involves a combination of batteries must be ensure the consistency of batteries, so battery production equipment set a higher and more professional requirements, so much equipment investment, in general, the construction of a production line of lithium iron phosphate batteries at least 5,000 million start-up capital. Business enterprises will be very difficult to enter this field, the traditional battery manufacturers will have a greater advantage. The following table lists the main domestic batteries production enterprises and their situation.

IV Summary

Lithium iron phosphate market is a huge market, pure cathode material, can reach several hundred billion global scale, the size of batteries downstream industries, the scale can be over 500 billion. Meanwhile, China in this industry, whether in technology, equipment, raw materials and markets are some of accumulation, with the foundation to develop this industry. Point in time, we believe that the next 2-3 years, lithium iron phosphate may have a significant technological breakthrough to boost the market breakthrough. From the business perspective of investment in the industrial chain of lithium iron phosphate, we believe that cathode material, separator, electrolyte some of the unique advantages of the enterprises will be cause for concern.

Days of storage batteries into the South African market can

Recently, the South African solar manufacturers to days to study group, and live day to purchase solar energy storage battery group.

South Africa is the largest producer of electricity, before power has been adequate, cheap electricity, but the last two years, frequent nationwide electricity shortage. National saving as an important measure, the South African government in May last year the country began actively promoting solar energy, issued a series of preferential policies, vigorously popularize solar power, solar energy and solar lights and other traffic lights.

The South African companies to come to China, aims to select high quality solar energy storage batteries. Related businesses in the domestic field trips several times after the final selection of days to the South African company Group. Storage battery manufacturers in South Africa ordered the first batch of products will use solar power system in South Africa, the future South African National solar, wind and lighting systems engineering in the gel used in storage batteries are directed to the Group from the days of purchase, while days to the South African Group provide comprehensive technical support and after-sales service.

At present the main power battery technology performance and price comparison

Ni-MH battery with safety, cost and other advantages, has become a hybrid vehicle (HEV) battery mainstream; but the energy density of nickel-metal hydride batteries, the efficiency so low, is not suitable for hybrid or pure electric severe car battery, and lithium-ion batteries (including lithium cobalt oxide, nickel cobalt manganese, lithium manganese oxide and lithium iron phosphate, etc.) with high specific capacity, is expected to become the future than the power characteristics of severe mixed (more than 40% lower fuel consumption) and even the first choice for battery electric vehicles.

The main components of electric vehicles is the motive power batteries, electric motors and energy conversion control systems, at present, which is the technical threshold of the highest power batteries, the most profitable part. According to NREL (National Renewable Energy Laboratory) statistics show that the current cost structure of new energy vehicles, the HEV battery accounted for 26% of the cost, slightly lower than the engine; for PHEV20 (pure battery mileage 20 km), the battery costs accounted for 39%, while for PHEV40, battery costs accounted for 51% cost of vehicles; for the future of electric vehicles, power battery is expected to more than 60%.
