Although the rapid development of China's power battery industry, but the power battery model too much and size specifications are not unified, "small and scattered" manufacturing is not conducive to the healthy development of power battery industry, is not conducive to competition with Japanese and Korean enterprises. The industry said that China's lithium battery industry before there is no uniform production standards, leading to the development of the entire industry chaos, showing "every family has standard, uneven quality" and so on. In the long run, large-scale production will be the key to reducing R & D and production costs. Lithium product specifications size of the standard release, will promote the scale of production enterprises to accelerate the standardization of China's manufacturing process.
China North Institute of Vehicle Power Battery Laboratory Director Wang Zedong has repeatedly stressed the significance of standardization for the power battery industry. He believes that the power battery to extend the life, to achieve echelon use, must be standardized production.
Lithium battery standardization is the development of the industry context, "standardized manufacturing, large-scale manufacturing" is the fundamental way to reduce battery costs. But in the standard introduction of the same applause of the environment, we still hear a different voice.
We understand that some companies believe that the state issued several standards for the enterprise is not practical. Only from GB / T34013-2017 "electric vehicle power battery product size" is concerned, some companies that the single cell size standards for enterprise development and no significant promotion, but will hinder the development of enterprises, resulting in business waste.
Although there is a voice of doubt, but most industry insiders have realized the importance of standardization of battery manufacturing, but the actual implementation process is relatively slow. Power battery standardization of manufacturing, then the standardization of lithium battery to promote the existence of what difficulties?
The industry has summarized the following two reasons: First, the power battery industry is not yet mature, different enterprises in the power battery selection, design, connection and other aspects often can not reach a consensus, each for the standard understanding is not the same, it is difficult to unify ; Secondly, from the perspective of car prices, the choice of power battery is often based on the degree of mastery of battery technology and product positioning, power battery passive form of the type, model and other technical parameters are different.
