Wang Binggang: How to judge whether the power battery is reliable

Wang Bing-gang, director of the National 863 Program's Energy Conservation and New Energy Vehicle Major Project Supervision Experts Group, wrote on his blog a few days ago that with the development of the new energy auto industry, its core component, the power battery, has received much attention. It can be said that who owns the power battery industry not only means that it has the core of the electric vehicle industry, but also means that it has great wealth and benefits. Therefore, automotive power batteries have become a hot spot for investment. In China, where electric vehicles are still difficult to start, hundreds of large and small battery factories have been built in just a few years. “Many people have doubts about this phenomenon. There are also many discussions in the community. I often get calls from the media and related people and ask me how to look at this phenomenon. There are many depots who have asked me so many battery factories. Which family is more reliable?"

Wang Binggang pointed out, "Which companies may be the best in the future? I think we should have at least the following three points: 1. Leading product R&D capabilities. 2. Excellent quality control system. 3. Solid economic strength."

Wang Binggang explained in detail that the battery company's competition is the competition in product development. A company that does not have a good R&D team, does not have sufficient technology, and does not have sufficient R&D investment can hardly succeed. Second, at present, many battery companies rely mainly on the inspection and screening of the production end to control the quality. This is a wrong and helpless method. The products that have been eliminated become waste products, causing huge waste and increasing costs; products that have passed the inspection are, in essence, not good products, but their hidden defects have not been detected, and they are likely to be used for some time. Will be exposed. If a battery company does not have the consciousness and ability to ensure product quality from the ground up, it will sooner or later fail. Finally, because the electric vehicle industry is still in the lead-in period in general, the scale of production is still very small, and the output value is still small. Although the state gives a certain subsidy, I am afraid that it is still difficult to make profits, even to lose some money, and this time Not too short. Therefore, there is no certain economic strength, and I am afraid it is difficult to maintain and develop.
