According to statistics, China currently has more than 760 lithium battery production enterprises, which claim to produce more than 150 power batteries. As of July 8, the Ministry of Industry announced a total of four batches of "automotive power battery industry standard conditions" business directory, a total of 57 power battery companies selected. According to the current policy, power battery catalog and new energy car recommended directory linked, only the use of power battery in the announcement of the enterprise directory, the new energy vehicles may enter the recommended model directory, and then access to national financial subsidies.
According to Ningde era of new energy technology Co., Ltd. Yang Qi, director of marketing, power battery technology system is very complex. Power battery system performance depends on the basic materials, quantum simulation, electrochemistry, technology, electronics, software development, mechanical design, thermal management, reliability, predictive, security testing, intelligent manufacturing, quality management, vehicle design, manufacturing Information management and so on more than 10 professional disciplines, is worthy of the name of high-tech.
At present, the power battery encapsulation form mainly sub-hard shell, soft package, cylindrical three, each have their own advantages and disadvantages. Among them, the hard shell power battery security, cycle life of up to 4000 or more, the cost is higher; soft battery power battery safety in general, the cycle life of 2000 times, the cost of center; cylindrical battery safety in general, the highest cycle life Can only reach 1500 times, the lowest cost.
In addition, the power battery in the research and development methods can also be divided into positive development, non-forward development, outsourcing development, which will affect the use of power batteries in the car. Power battery quality and batteries, modules, BMS, battery pack design and integration side are also inextricably linked.
