U.S. astronauts to the station a new battery

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 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

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.

Sanyo $ 1.8 billion investment in rechargeable batteries, solar cells

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

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

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?

Taiwan solar cell factory capacity planning

Taiwan solar cell factory capacity planning

Sun Branch (3561) in the first quarter profit will exceed last year, continuing the recent influx of orders, the visibility to see the end of the industry-leading, popular trading quarter by quarter. In HTC (2498) Cher Wang, chairman of the relevant under the influx of capital, nearly forty percent increase in capacity planning this year to 500 megawatts (MW).

Corporation that, under the revised solar subsidies in Germany under the impact of the global solar cell factory orders fell in the first half in general visibility, Sun Division order to see the end, in addition to robust foreign orders mean that the company is Taiwan's largest solar cell factory environment, break the shackles leader.

Sun Division operating Great Leap Forward, by mainland media attention. Yesterday (14) days, including First Financial, CCTV, People's Daily and other well-known mainland media visit, the first stop will be to visit the Sun Division, is the only respondents to this line of solar-cell factory in Taiwan.

Sun Division net income 166 million yuan last year, net income per share 1.25, is a local with the industry, "earnings per share of the king." Operations continued warming in the first quarter, the first in February to reduce the number of days from the impact of a single month to write 63 million yuan profit is still success, in March sales to 560 million yuan more rewriting the high revenues 1.625 billion yuan in the first quarter, quarter growth rate of 56% growth rate ranks highest in the industry, single-quarter earnings will exceed last year.

Head of Sun Microsystems said yesterday that the recent European mainland and other places continued influx of orders, production can continue to clogging. Consider the capacity is limited, a lot of new customer orders are "not connected." Industry for the third quarter, compared with orders still uncertain, the Sun Division has been discharged by the end of the order, the best visibility.

To meet customer demand, Sun Division scheduled by the end of this year's production capacity increased to 132MW is only 360mW, about 40% of the repair to 3,500 MW. Head pointed out that the Sun, with production capacity of funds, primarily invested 500 million yuan Cher forces involved in the company private inject.

Sun Head stressed that sufficient cash on hand, especially after the Cher-related capital investment, the company will follow the layout of much help.

Cher Wang is currently Sun through the trusted subjects to attend to participate in the board of directors, shareholders will also this year will add two Xidong Shi, Sun Microsystems will formally introduce the relevant forces in the Section Board of Directors.

Sun is working on a new production section set up, the end of the quarter will be raised to 252MW or more, by the end of the installation of capacity up to 430MW, through the adjustment process within the company, up to 500 megawatts of output. In addition, investment in the mainland turn 80mW Jiangxi Sun Outsourcing original capacity will be adjusted upward. New capacity being added this year after the operation will be able to go quarter by quarter Yang.

iPhone sucks! Microsoft Kin phone batteries available one week

We know, Kin and Zune HD is the same strain, and therefore will see the ZUNE Kin on the player, but if you have thought about, Zune HD applications can run in the top of Kin? But do not get too excited, because Microsoft announced that this interface has been shut down, and claimed Kin need to focus on the future status of their upgrade.

But clearly, this system has drawn a line and WM7 the same time, Microsoft hopes to reach one week Kin realm of one charge, so they designed a simple interface, and there is no 3D games these complex applications, there is a confirmation Kin do not support the expansion card is, but all content can be uploaded to Microsoft's storage server. Compared to the iPhone, Microsoft has chosen to go this route might be able to open up their phones and then place in the world, after all, the iPhone battery has been criticized for trouble.
