From June 28th, 2020 to October 28th, 20201October 28th, 2020, some 2020 Weimar cars which were produced from June 8th, 2020 to September 23rd, 2020 and were equipped with power batteries of battery model ZNP39 14895A-75A were recalled, totaling 1282 vehicles. Since the protagonist of the incident is Weimar Automobile, a well-known new energy enterprise, this recall information has aroused great concern.
The recall originated from impurities mixed in the battery production process.
Through inquiry, Bian Xiao found that the power battery manufacturer with the cell model of ZNP39 14895A-75A is ZTE High Energy Technology Co., Ltd., which is mainly engaged in the research, development, production and sales of power batteries for new energy vehicles. It is worth mentioning that this company is controlled by ZTE New Energy Sector with a registered capital of 500 million yuan. It can be said that it is a professional manufacturer of power batteries.
The reason for the recall is mainly the safety hazard of the power battery. ZTE High Energy mixed impurities in the battery production process, which led to abnormal precipitation of lithium in the power battery. In extreme cases, it may lead to short circuit inside the battery, leading to thermal runaway of the power battery and fire risk.
On June+10/October, 5438, many suspected spontaneous combustion incidents occurred.
The fuse that triggered the car factory to choose to take the initiative to recall was not unrelated to the suspected spontaneous combustion of Weimar New Energy in June+10/October, 5438.
Two of them originated in Fujian. According to relevant media reports, Weimar Automobile put 80 EX5 electric vehicles in Shaowu City, Fujian Province. Two of them caught fire on1October 5 10 and 13 respectively.
One of the car bodies went too far, which was still serious. Another car was parked on the side of the road without any operation such as charging. After burning, only the frame was left, and the accident caused the vehicle to be completely destroyed. Fortunately, according to relevant media reports, there were no reports of casualties.
There was another suspected spontaneous combustion incident yesterday. 101On the evening of October 27th, a Weimar electric car exploded in the Institute of Mechanics, Chinese Academy of Sciences, North Fourth Ring Road, Beijing. Judging from the pictures on the scene, the smoke is rolling, which inevitably makes people feel very worried about the safety of new energy vehicles.
Weimar's attitude towards spontaneous combustion is worthy of recognition.
In fact, spontaneous combustion of new energy vehicles is not uncommon, and it seems that people have become accustomed to it. One of the reasons is that the new energy industry is developing rapidly, and the quality control of power battery manufacturers is not as high as consumers expected. This time, ZTE High Energy mixed impurities in the battery production process is a typical representative.
Judging from Weimar's active choice of recall, it is still worthy of recognition. People who often pay attention to new energy vehicles know that some so-called new forces have more or less problems with their electric vehicles. When a suspected spontaneous combustion accident occurs, its model likes to play word games. Let alone take the initiative to recall.
So from this perspective, Weimar did a good job in dealing with the problem after it happened. After the spontaneous combustion of two taxis in Fujian, Weimar made it clear that the cause of the accident had initially determined the battery problem, and proposed a solution to replace the high-quality battery immediately. So we can see that the State Administration of Market Supervision announced the recall of Weimar yesterday. Judging from the speed, it is still relatively fast.
Auto Network Comments: Safety standards of new energy industry need to be improved urgently.
Undoubtedly, with the support of the policy level, the development speed of new energy vehicles is quite rapid. According to the data of the Federation, the sales volume of new energy narrow passenger cars in September was1110,000 units, up 84.2% year-on-year and 18.5% quarter-on-quarter, much higher than the overall automobile market. Among them, the number one model has a sales volume approaching10.5 million units. A large number of new energy vehicles need to improve the safety and quality standards, especially the power battery, because it is related to people's life safety. Weimar's recall not only reflects the high safety awareness of the car factory, but also reflects the determination of the General Administration of Market Supervision to strictly regulate the new energy automobile industry.
