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 vehicle power lithium batteries, motor, electric control, etc. are supplied 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 battery enters the market, you can't escape two questions: Scrapped and recovered, especially in the field of battery recovery, there is currently a lack of standards, data showing 1 20 grams of mobile phone lithium-ion batteries can pollute three standard swimming pool volumes, if abandoned on the land, can make 1 square kilometers The land pollution is about 50 years, and the level of contamination of about 1 ton can I know.
In the above questions, the reporter interviewed Wang Zi Dong, director of the National 863 Electric Vehicle Major Power Lithium Battery Test Center. In his opinion, there were two situations before the quality insulation: 1. Problem in the battery pack 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, enter the step-use state, and finally recycled.
After the maintenance of the maintenance and steps "" 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 because the battery quality is uneven, whether it is private consumers or corporate customers, the performance of the battery after the warranty period is worried, the reporter and several companies have also found 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. With regard to batteries that cannot continue to be used, the company will pay for it. "The reporter learned when communicating with the staff, due to the different types, capacity, etc.
About the power lithium battery that does not reach the standard of electric vehicles, theory should enter the stage of the ladder. 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.
Correlation from the rails of the battery, the difficulty of battery recovery is larger. The power lithium battery faces the recycling difficult power lithium battery in the field of recycling is the lack of recycling standards. In the face of the prince, how to carry out steps is also lack of standard, "how to reach the battery capacity to enter the next step.
There is no clear standard, and 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 production cost, leading to the lack of recycling enthusiasm, plus the lack of encouraging policies, and the powerful and lithium battery recovery is extremely difficult.
Power lithium battery from production, use, ladder, recycling should be a complete closed-loop system, but due to the lack of corresponding standards, there are too many batteries, lack of recovery ability, so that there are many problems in the lack of power lithium batteries, even There will be low use efficiency and more serious pollution problems. These situations have violated, visible, a benign industrial ecosystem, can't unknown to government, companies and individuals. [Comment] Solving the powerful lithium battery problem of overhanging instructors Need to put a bottleneck of the schedule power lithium battery is a boss, one is high in the production, and the consistency requires high, one is using the end, can not overtake.
In addition to these two issues, there is a problem: what should I do if I have a quality insurance? At present, the author did not see a good solution. Previously, the Ministry of Finance, the Taxation Administration and the Ministry of Industry and Information Technology were clearly mentioned in the "Notice on the Exemption of New Energy Automobile Vehicle Purchase Tax", and the relevant models must meet the national standards, but also "to the new energy vehicle power lithium battery" , The supply of key parts such as motor, electric control is not less than 5 years or 100,000 kilometers (with the first-lastst) warranty. ".
The first stage of my country's first stage has begun in 2009. In those years, the power lithium battery in which it put into use is short, the number, the quality assurance requirements have no uniform provisions, and the problem of the quality of the battery exposure is not that protrude. Nowadays, in recent years, my country's new energy vehicle sales have risen, and the number of power-based lithium batteries exceeding the quality insulation also presents the rise in geometric grade, even if the number of batteries in the first stage is less, it has also passed the warranty period.
After passing the quality of the quality of battery exposure is getting more and more. After warranty, the power lithium battery also has 80% of the energy density, but it is not suitable for use as a powered lithium battery. It is also more than enough, such as the battery ladder eliminated on the car.
This practice has successful precedent abroad. Due to the continuous recycling measures and enhanced the scale effect, Tesla's 18650 cylindrical batteries used on Models decreased by about 40%. Tesla's price is always very high, if there is no battery-recycling, the price will be higher.
However, domestic high-inspected battery recycling is not ideal. According to the author, BYD produces sales of electric vehicles, also involved in the field of photovoltaic power generation and energy storage, and the recycling of power lithium batteries is better. Other new energy motors are almost single production and sell electric vehicles, and it is not so optimistic on the recycling of batteries.
At a new energy vehicle seminar, a specialist in the field of communication, he told the author, on the backup power of the communication base station, they are not very willing to use the old battery from the car. I used it before, exposed the problem. The technical level of each lithium-ion battery company is uneven.
It uses different brands of old batteries in the same base station. There is a lot of batteries, some crude batteries, the use of attenuation in the base station is also very fast, these batteries Rapid attenuation affects other batteries. In order to maintain consistency, the old battery eliminated by the same company in the same base station, but there is always a quantity, the individual base station should match other brands of batteries.
In the base station, there is no electric car to use so demanding requirements, but it is also necessary to do maintenance. After all, it is a battery that is eliminated from electric cars. It does not to ignore the cost of maintenance, especially some base stations are relatively far, it is not easy to maintain.
The person said that from a single battery purchase cost, the price of the old battery is relatively low, but from the full life cycle, the cost of the old battery is not seen as an advantage. Solved the issue of the line of warranty, should adopt systemic solutions. First, policy measures are in place; the second is to produce, use, recover the interests of several links together.
At present, the automotive company recycles the battery and finds other companies, this market economy is not unable, the author believes that in the early days, the relevant departments should introduce some encouragement policies. After the system matures and improved, let go of the market. No visual use.
It has been used in the field of energy storage or communication, and these practices are related to the interests of BYD, and they certainly have enthusiasm. Other companies are in their own small abacus, and the enthusiasm is not so high. The author recommends that the battery eliminated from electric car users, reaches the test standards of the communication company, can consider some calls for the owners, or Internet traffic discounts, etc.
This can prompt users to drive electric vehicles correctly, but also let companies and users willing to pay the battery to regular units to prevent flow to the black workshop. The longer the time, the longer the quality insulation battery will be more, the solution should be put on the agenda!.
