Why is BMS the core competitiveness of the power battery PACK factory?

Why is BMS the core competitiveness of the power battery PACK factory? There are three important reasons for this. The first reason is that the battery cell will eventually become a standard product. The second reason is that BMS is very complicated, and BMS has strong variables. The third reason is that lithium batteries in conventional industries must be equipped with BMS to be used normally. Power batteries are still a product series that is rapidly advancing, and the upstream batteries will also change the specifications of the supply according to actual demand in order to adapt to the development of the power battery industry. The final development of power battery cells will be as standardized as mobile phone batteries. In the end, there will not be many battery cell factories that can live well in the field of power batteries, and a large number of battery cell factories will slowly disappear. Any battery cell factory in the world is researching electrochemistry and materials. The vast majority of talents are concentrated in this field. It is difficult for them to have a good understanding of BMS, which is extremely demanding on electronics and systems. , There will be no good achievements, and it is impossible to make competitive BMS products and battery packs. Therefore, in the end, the battery cell factory and the PACK factory will inevitably divide, and they will have a professional division of labor. This is the law of nature and the law of market competition. For the second reason, the complexity of BMS and high system requirements are the basis for PACK competition. Why is BMS more complicated? Because BMS involves many things, not only knowledge of battery, but also the whole system (electric vehicle or energy storage, etc.) is required. Not only must understand electronics, but also understand structure, not only hardware , You must know the software, you must do a good job of BMS, you must be professional in many things such as electronic technology, electrical technology, microelectronics and power device technology, heat dissipation technology, high voltage technology, communication technology, anti-interference and reliability technology, etc. It is a responsible system engineering. At present, it can be seen that PACK companies mostly focus on the integration of power management systems, and rarely see manufacturers willing to invest in battery material development. With the slowdown in the growth of terminal markets such as smartphones, tablet computers, and mobile power supplies this year, many leading PACK companies are increasing the integration of the industrial chain and actively deploying power and energy storage in emerging markets. But the technical content is not high, so it belongs to the Red Sea market. Only the supply chain belonging to the brand has the economic scale and it is easier to survive. The quality of a BMS design directly affects whether the battery meets the needs of customers. And BMS is the fundamental solution to product demand.
