Frequent rainfall led to water accumulation in urban areas, and even "car splashing" was staged again. After many reports on the flooding treatment of conventional fuel vehicles, this newspaper focuses on the treatment of new energy vehicles, especially pure electric vehicles. Although the new energy vehicle is waterproof and not as fragile as expected, once it is soaked in water, the damage of the power battery can not be underestimated, which is a great loss for the owner.

Can new energy vehicles be scrapped after soaking in water?

At present, the cumulative output of new energy vehicles in China has exceeded 2.8 million, and the promotion scale ranks first in the world. The unprecedented promotion of new energy vehicles can't help but make consumers worry: How long is the life of new energy vehicles? How long is the life of the power battery?

Experts estimate that the life of power batteries is usually 6-8 years. If 20 14 is designated as the first year of new energy vehicles in China, then the "mighty" first wave of power battery retirement is coming to us.

"Anyway, it's already a soaking car, and I won't drive it again." 20 18 Mr. Luo, who lives in Shenzhen, accidentally got stuck in a car because of the local rainy season. "Insurance lost the car, and the amount of compensation is still appropriate. No one collects the second-hand market, and the new car is directly replaced in the 4S shop. "

According to Mr. Luo, new energy vehicles are not easy to sell in the used car market, let alone soak cars. However, counting the insurance payment and the replacement of the old car, Mr. Luo, who put on a new car, "added more than 30 thousand" and drove the new car home.

The owner's loss caused by a natural disaster, in Mr. Luo's view, is "there is a silver lining behind the dark clouds." There is no lack of insurance, but at the same time, we are also thinking, where is the power battery soaked in water?

Sales first-line recycling is limited

Where did the retired or scrapped new energy vehicle power battery go?

This is a question that is extremely difficult to answer and cannot be answered accurately.

The reporter entered the keyword "power battery recycling" through Baidu search engine, and the first four articles on the home page were all advertisements for power battery recycling. Click on the links separately, and these advertisers are power battery recycling units all over the country. Although the company's address is different, the business categories and main advertising slogans are very similar, such as "recycling of various power batteries", "national high price" and "door-to-door recycling" ... On the premise that the qualifications of these enterprises cannot be confirmed for the time being, the reporter subjectively feels like "collecting junk in the group".

Industry experts said, "We will not judge the qualifications of those social recycling institutions for the time being. However, last year, seven ministries and commissions issued management measures for battery recycling of new energy vehicles. The simple understanding is that car companies are responsible for recycling the power batteries of new energy vehicles, and how many electric vehicles are sold, how many batteries are recycled. "

"Whoever sells it, whoever recycles it" is a simple and direct policy, so let's start looking for the whereabouts of waste power batteries from here.

The reporter visited a number of new energy vehicle sales enterprises and new energy vehicle production enterprises in Changsha respectively, and the responses were more questioning.

"Maybe our store is too new, and there is no case of recycling batteries!" A Geely automobile dealer in Changsha told reporters.

"Manufacturers have recycling ability, but our store can only recycle more than a dozen sets a year." The local dealer of BYD Auto Changsha explained to the reporter, "Most of the batteries of the first batch of new energy vehicles are still in use, and the data provided by a single store is also very loose. In 20 18, we only restored the 15 group, and there are currently 9 groups this year. "

"Innovative" Recycling of Automobile Enterprises

There is no accurate data in the recycling line, and the reporter asked a number of new energy automobile manufacturers for verification.

An insider of an independent car company told reporters that it is difficult for car companies to recycle these batteries only by relying on dealers and consumers. Enterprises have established thousands of recycling outlets for power batteries of new energy vehicles all over the country, but the effect is not ideal. "The so-called not ideal, even can't give you an accurate number. There are also dozens of batteries a year, but this is almost negligible for the recycling channels we have invested. "

The recycling quantity of power batteries is limited. In the limited quantity, it needs to be classified again: some can be reused, and some can only be handled by "more professional" enterprises.

When the reporter visited a joint venture factory in China, the staff told the reporter with great interest that the VGA cars in the factory (automatic cars for transporting parts) were all driven by recycled power batteries. "Although these cars can no longer be used, they can still perform tasks in these low-energy cars. The reorganization of these used batteries and cars was also completed by our own electrical team. " It is understood that VGA cars are quite common in automobile manufacturers, but most of them are complete sets of cars purchased by enterprises, using brand-new lithium batteries, such as "waste batteries into cars" used by companies, and the number is very small.

"When the battery can no longer be used in VGA cars, it will be sent to raw material enterprises or battery manufacturers. After all, they have better recycling hardware and technology. "

BYD, which is both an automobile manufacturer and a power battery manufacturer, has many successes in power battery recycling.

According to BYD insiders, "We rely on BYD 4S stores for temporary collection and temporary storage, and then recycle them to BYD recycling points; In the taxi industry, we classify it as a big customer, in which there is a special centralized point for maintenance, and this centralized point also has the responsibility of temporarily storing batteries; Finally, we will recycle batteries in different States to the corresponding factories for processing. "

Even so, in practice, "the amount sent to Huizhou for dismantling and recycling is even less." It's not that we don't have the technology, but that the number of recycled batteries is too small. "BYD insiders revealed.

Big data helps upstream enterprises

2065438+May 2009, Hunan Provincial Department of Industry and Information Technology, Hunan Provincial Department of Science and Technology, Hunan Provincial Department of Ecology and Environment and other departments jointly issued the "Hunan Province New Energy Vehicle Power Battery Recycling Pilot Implementation Plan", in which Thornton New Energy and Hunan Hongjie New Materials Co., Ltd. (both belonging to Sander Group) entered the list of pilot units for new energy vehicle power battery recycling in Hunan Province.

According to Wen Yibo, Chairman of Sander Group, Thornton New Energy has advantages in power battery recycling. Sander Group owns 13 waste household appliances dismantling plants and thousands of recycling points for environmental sanitation renewable resources. In addition to the huge recycling outlets, the accumulation of big data technology of Thornton New Energy has also become the basis for the traceability of power batteries. It is understood that Thornton New Energy's lithium battery cloud platform has made the best interpretation of big data technology. Based on big data technology, the platform realizes disassembly-free recycling, accurate recycling and step-by-step recycling of power batteries. In the operation of new energy vehicles, the safety of operation is ensured by data mining of power batteries. In June this year, 5438+ 10, the 65438+ ten thousand tons/year lithium battery recycling project of Sander Group started in Shaoyang.

However, even if the advantages of big data and recycling point network are obvious, the batteries cannot be returned to car companies and upstream enterprises, and the advantages have not been fully exerted.

At present, the main body responsible for recycling power batteries in China has always been car companies, but the ownership of batteries belongs to consumers. Consumers' awareness of battery recycling is relatively weak. In this way, both car companies and upstream companies are extremely embarrassed. They don't have the ownership of retired power batteries, and the established recycling channels have nowhere to play a role.

Insiders said, "Whether the battery can be recycled after the electric car is sold is a big problem facing the whole industry. Consumers definitely want to sell at a high price, but car manufacturers can't give too high a price. Selling to a small workshop with convenient transactions and higher bids has become the easiest choice. "

According to Wen Yibo, chairman of Sander Group, the road of financial subsidy is unsustainable, and the solution to the problem is to let regular enterprises receive more waste batteries through sailor adjustment. Similar suggestions also occurred in car companies. "The government will promote the corresponding local enterprises in the demonstration cities to recycle batteries through corresponding financial subsidies, and then the market will naturally choose after the scale effect is formed." They think this is a more pragmatic approach at present.

[Data] 900,000 tons

The cumulative supporting capacity of power batteries in China exceeds 900,000 tons, and the industrial scale ranks first in the world.

6 to 8 years

The cycle life of the battery is calculated according to 800 times, and the battery needs to be replaced after the vehicle travels 240,000 kilometers, which means that the life of the power battery is 6-8 years.

200,000 tons

According to the prediction of China Automotive Technology and Research Center, the power battery will enter the stage of large-scale retirement, and will exceed 200,000 tons (24.6GWh) in 2020. If 70% of the batteries can be reused step by step, about 60,000 tons of batteries need to be scrapped.

3,500

According to the information displayed by official website of the Ministry of Industry and Information Technology, so far, the number of outlets has exceeded 3,500.

25 billion yuan

With the increase of power battery market and recycling scale, the recycling market of power battery will exceed 654.38+000 billion yuan by 2020, and it is expected to reach 25 billion yuan by 2023.
