What should I do if the electric vehicle power lithium battery has passed the warranty?

The National Treasury, the State Administration of Taxation and the Ministry of Industry and Information Technology issued clearly mentioned that the car enterprises must enter the "New Energy Automobile Model Directory" exempted from the vehicle purchase tax "must be New energy automobile power lithium-ion battery, motor, electric control, etc. The supply is no less than 5 years or 100,000 kilometers (with the first-serving) warranty. What happens after the warranty of electric car batteries, how to solve it? Dynamic lithium-ion batteries enter the market to escape two problems: First, the battery is most worried about the battery repair time, the battery maintenance is too high and the main body is unclear; second is the battery The scrap and recycling, especially in the field of battery recovery, currently lacks corresponding standards, data showing 1 20 grams of mobile phone lithium-ion batteries can pollute the water of 3 standard swimming pools, if abandoned on the land, can make 1 square Kili land pollution is about 50 years, and the degree of pollution of about 1 ton can I know.

In the above questions, the reporter interviewed Wang Zihe, director of the National 863 Electric Vehicle Major Power Lithium Ion Battery Test Center. In his opinion, there were two cases of the power lithium-ion battery exceeding the quality insulation: First, individual batches in the battery pack There is a problem, you can find battery manufacturers through the vehicle company; Second, the battery pack is completely scrapped, which is thoroughly replaced by the battery pack, no longer suitable for electric vehicles to enter the step-use state, and finally recycle. ■ Maintenance and steps of over-guarantees "" warranty period is not equal to battery life.

"Prince winter told reporters." In fact, consumers do not have to worry about battery performance, in general, as long as the battery capacity is higher than 80%, electric cars can be used normally. If during use, problems with individual batches only need to replace the corresponding cell, do not replace the entire battery pack, so the cost will not be too high.

"But due to the uneven quality of the battery, whether it is private consumers or corporate customers, the performance of the battery is worried, the reporter and several companies have also discovered that many companies have launched the corresponding services for this phenomenon. Such as extended and discount recycling services, to cancel the customer's doubts. China Aviation Lithium (Luoyang) Co.

, Ltd. is responsible for the staff of the domestic market told reporters. "We have adopted bus customers for five years of warranty, and signed the extension agreement for paid services.

Companies will be re-received by the batteries that cannot continue to be used. "The reporter learned when communicating with the staff, due to the different types, capacity, etc. Dynamic lithium-ion batteries related to the standard of electric vehicles, theoretically, should enter the stage.

The market personnel of China CITI-UNITA said that the battery replaced by electric vehicles can be used in the civilian field, and can continue to be used in new energy distributed power stations, street lights, communication base stations and other energy storage, and can also be used in electric venue vehicles. On low-speed electric vehicles such as tour vehicles, golf carts, implementing the rails of the battery to save costs. Phase related to battery steps, battery recovery is more difficult.

■ The biggest problem in the face of recycling difficult power lithium-ion batteries in the field of recycling is the lack of recycling standards. In prince, it is also a lack of standards, "the battery capacity can be entered. A ladder utilization does not have a clear standard, what extent cannot be used again, and there is no clear standard to enter the recycling process.

"In addition to lack of recycling standards, the company's qualifications have become another bottleneck that restricts battery recovery." With the deepening of battery attenuation, the safety performance of batteries is constantly decreasing, and the recycling company must have corresponding means and ability to have corresponding qualifications. Unable.

"Prince Winter said to the reporter that it is quite large to do the safety recycling of the battery. Reality is that domestic lithium-ion battery varieties have a wide variety, and there is no fixed standard for battery construction. It is difficult to form industrialized management.

According to data, there is data showing that the cost of recovering lithium carbonate from lithium-ion batteries is still company direct. More than 5 times more of the production cost, leading the company lack of recycling enthusiasm, plus the lack of encouraging policies, and the driving force of lithium-ion battery is in the face of great difficulties. Power lithium-ion battery from production, use, ladder, recovery should be a complete closed-loop system, but due to the lack of corresponding standards, there are too many batteries, the lack of recovery ability, so that there are many problems in the lack of power lithium-ion batteries Even if the use efficiency is low and more serious pollution problems, these situations are in violation of the original intention of the development of electric vehicles, visible, a benign industrial ecosystem, can not open the government, company and individual cooperation and efforts.
