What happens after the warranty period of the electric car battery? How to solve it?

The "Notice on the Exemption of New Energy Vehicle Purchase Tax" jointly issued by the Ministry of Finance, the State Administration of Taxation and the Ministry of Industry and Information Technology clearly mentions that the vehicle enterprise must enter the Catalogue of New Energy Vehicle Models Exempt from Vehicle Purchase Tax. The key components of new energy vehicles such as power batteries, motors, and electronic controls are guaranteed to be no less than 5 years or 100,000 kilometers (whichever comes first). What happens after the warranty period of the electric car battery, and how to solve it?

After the power battery enters the market, it can't escape two major problems: First, after the battery is sold, consumers are most worried about the problem that the cost of battery repair and replacement is too high and the maintenance subject is not clear after the warranty period. Second, the battery is scrapped. And recycling, especially in the field of battery recycling, there is currently no corresponding standard. The data shows that a 20-gram mobile phone lithium battery can pollute the water of three standard swimming pools. If it is abandoned on the land, it can pollute 1 square kilometer. About 50 years, the pollution level of a battery pack of about 1 ton can be imagined.

On the above issues, the reporter interviewed Wang Zidong, director of the National 863 Electric Vehicle Major Special power battery Test Center. In his view, there will be two situations after the power battery exceeds the warranty period: First, there are problems with individual batteries in the battery pack. Through the vehicle manufacturers to find battery manufacturers for maintenance; Second, the battery pack is completely scrapped, which requires a complete replacement of the battery pack, the battery that is no longer suitable for electric vehicles will enter the cascade utilization state, and finally recycled.

Maintenance and cascade utilization after over-guarantee

“The warranty period is not equal to the battery life.” Wang Zidong told reporters, “In fact, consumers don’t have to worry too much about battery performance. Generally speaking, as long as the battery capacity is higher than 80%, the electric car can be used normally. In the case of individual batteries, only the corresponding batteries need to be replaced, and the entire battery pack does not need to be replaced, so the cost is not too high."

However, due to the uneven quality of the battery in the industry, both private and corporate customers are worried about the performance of the battery after the warranty period. After communicating with several companies, the reporter found that many companies have launched corresponding services for this phenomenon, such as Deferred and discounted recycling services to dispel customer concerns.

The staff responsible for the domestic market of AVIC Lithium (Luoyang) Co., Ltd. told the reporter, "We have taken the warranty for five years on the basis of the warranty for the bus customers, and then signed the extended warranty agreement for paid services. For batteries that cannot be used continuously, the company will recycle at a discount."

When communicating with the staff, the reporter learned that because the type and capacity of the batteries are different, it is difficult for enterprises to give uniform extension insurance fees, and most of them are negotiated and resolved according to specific conditions.

For a power battery that does not meet the standard for electric vehicle use, it should theoretically enter the stage of utilization. The market personnel of CITIC Guoan Mengli said to reporters that the batteries replaced by electric vehicles can be used in the civilian field, and can continue to be used in energy storage fields such as new energy distributed power stations, street lamps, communication base stations, etc. On low-speed electric vehicles such as tour buses and golf carts, the use of batteries can be realized to save costs.

Battery recycling is more difficult than the cascade utilization of the battery.
