With the line rise of domestic new energy vehicle sales, the recycling and re-use problem of new energy vehicle power batteries is also mentioned. "In general, the capacity of the power battery cannot be used in new energy cars, but this does not mean that the bad battery has lost value, it can also be used as an energy storage or related power supply base station and Street light, low-speed electric vehicle. "Shanghai Jiaotong University Automotive Engineering Research Institute, Vice President Yin Chengliang said.
Referring to foreign experience, including general, Nissan has successful cases of using the power battery ladder. "However, according to I understand that all work related to this is still in theoretical stage. "China Battery Network founder said in the clear teaching.
In his opinion, "the state should introduce relevant policies to lead to establish and encourage enterprises to participate, together to improve the recycling and ladder use of power batteries, so as not to repeat resource waste and environmental pollution of environmental pollution in lead-acid batteries.". The so-called dynamic lithium battery is used, refers to the second use of disassembly, detection and classification by disassembly, detection and classification by disassembling the power battery after use.
The reporter understands that before the large-scale promotion and application of new energy vehicles, the domestic lithium battery market is mainly concentrated in the 3C field, and since the lithium battery capacity of these products is relatively small, the cost is not high, so it is recycling Not paying enough attention. With the sales growth of new energy vehicles, the vehicle power battery needs further highlight. China Automotive Industry Association statistics show that in April this year, domestic new energy vehicle sales reached 10,501, a year-on-year increase of 154% year-on-year.
Under the high-speed growth space of the new energy car market, the recycling and reuse of the power battery needs to be proposed urgently. According to data, in 2013, the domestic lithium battery market has more than 11 million kWh, of which the demand for electric vehicle market (mainly new energy vehicles) accounts for 26.52%, more than 2.
9 million kWh; 2011, this figure is only 960,000 kWh. At the same time, according to the data provided by the Institute of Higher's Lithium Electric Industry, in May this year, domestic mobile phone and laptop consumption lithium battery decreased by 2 and 4 percentage points, while electric vehicles and energy storage rose 4 respectively. One and 1 percentage point.
In the future, as the new energy car market is put on, the demand for the dynamic lithium battery market will usher in the explosive growth. Relative to 3C products, new energy vehicle power batteries account for up to 30% in the cost of vehicle, and only the battery capacity is less than 80%, it can no longer be used in new energy vehicles. In theory, after the power battery is eliminated, it will be fully used in the new energy distributed power station, affordable stronghold, streetlights and communication base stations.
"Relatively, the energy density of the energy storage power station on the lithium battery is low. "Yin Chengliang said. Zhang Qian, deputy general manager of the CCID Adviser Automobile Industry Research, if the new energy vehicle power battery ladder can be systematized and scale, which can undoubtedly reduce the production and use cost of new energy vehicles.
According to the introduction, before this, the 18650 cylindrical battery of Tesra, which is used by the electric vehicle production enterprise is reduced by about 40% from 2007 to 2012. "From the current point of view, Beijing, Zhejiang, including the national power grid, is committed to the powerful research of the power battery, put into the funds, the mission-use research project, but progress is relatively slow. "OfWeek Industry Research Center New Energy Analyst Sun Dongpu".
"The market of electric cars is not fully developed yet. In addition, the ladder of the power battery is completely feasible from the theory, but in the actual operating level, it is still a lot. "The Assistant of the Dean of the High Industry Lithium Electric Industry Research Institute said in an interview with the pen.
However, the problem is not only the case. "In the current situation of the industry, due to the battery route of my country's different cars, the battery specifications and the requirements of the battery are different, but also cause too much of the battery, excessive production, and also the market 'Is also a more difficulty of tradder. "Sun Dongdong said.
Outside the technical level, it is necessary to promote the tradder, apparently there is also a problem of industrial chain. At Sun Dongdong, due to the respective situation of my country's new energy automobile industry chain, the operator of the car, battery enterprises or battery rental, actively led to the driving of the dynamic battery ladder, has a large difficulty. "Before the related industrial chain has not formed a complete closed loop, it should also be driven more appropriately.
". In the "Energy Saving and New Energy Automotive Industry Development Plan" (2012-22020) ", the relevant government departments clearly propose" to develop power battery recycling management methods, establish power battery steps and recycling management system, Confirm the responsibilities, rights and obligations of the relevant parties. Guide power battery manufacturers to strengthen recycling of waste batteries, encourage battery recycling companies for developmental specialization.
"However, this plan has not made specific regulations on the responsibilities of the recycling process.
