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."
