What is the difference between China's power battery and the international advanced level? This is a hotly discussed issue between officials and practitioners in the electric car 100-person meeting.

According to relevant data from the Automobile Industry Association and the National Association of Automotive Power Battery Research Institutes, China's power battery industry as a whole cannot meet the requirements of complete vehicles, and there is a “systematic” gap compared with the United States, Germany, Japan, and South Korea.

The current problems in the field of power batteries in China are as follows: 1. Low specific energy: The current lithium battery has a specific energy of approximately 50-1000Wh/kg, which is less than one-third of the 2020 planning target. Electric vehicle mileage is generally not More than 200km, it is almost uncompetitive with traditional cars. Second, the cost is high: China's lithium iron phosphate battery system costs about 3-5 yuan / Wh, and the cost target for 2020 is 1.5 yuan / Wh, it is reported that Samsung's 2020 cost will be reduced to 1 yuan / Wh. Third, life: Although China's lithium iron phosphate battery life can reach more than 3,000, but because the battery consistency is poor, the system life is generally only 5-8 years (2020 target 10 years).

Dong Yang, executive vice president of the China Association of Automobile Manufacturers, said: "Honda's vehicle battery test facility has 300 devices and investments of up to $600 million. Each battery will undergo hundreds of tests, which is what I expected. 10 times.Relevant personnel said that if the battery is not tested in such detail, use bad batteries.I have already proposed with the relevant departments, I hope to build a battery testing laboratory from the perspective of the vehicle as soon as possible.The battery itself is very good, but There are still a lot of things that need us to work hard.”

When asked about the progress of the testing laboratory, Dong Yang said that everything is omnipresent: The laboratory is still in the stage of proposal, and the specific details are not disclosed.

Zhang Xiangmu, Director of the Department of Equipment Industry of the Ministry of Industry and Information Technology, stated, “How far our new energy vehicles can go depends on the power battery. Whoever has mastered the core technologies of power batteries will grasp the future of new energy vehicles. China’s new energy The rapid development of the automotive industry, but the gap in the system technology is still very large.Ministry of Industry and Information Technology will formulate "Automobile battery industry regulatory conditions" from the perspective of industry management, and promote the healthy development of the power battery industry.
