18650 li ion rechargeable battery

　　The role of 18650 li ion rechargeable battery BMS management system

　　The 18650 li ion rechargeable battery management system BMS is a control system that protects the safety of power batteries. It monitors the usage status of the battery at all times, takes necessary measures to alleviate the inconsistency of the battery pack, and provides guarantee for the safety of new energy vehicles.

　　The 18650 li ion rechargeable battery management system BMS determines the status of the entire battery system by detecting the status of each single battery in the power battery pack, and performs corresponding control adjustments and strategy implementation on the power battery system based on their status to achieve control over the power 18650 li ion rechargeable battery system and The charge and discharge management of each cell ensures the safe and stable operation of the power battery system.

　　Misunderstandings about 18650 li ion rechargeable battery BMS

　　1) The more functions, the better. The functions only need to meet the needs. More is not always better. The simpler the system, the higher the reliability.

　　2) Deliberately pursue the collection accuracy of parameters such as voltage or temperature. The reason is as above, the accuracy only needs to meet the needs. Excessive accuracy will not necessarily improve the performance of the BMS, but will increase the cost.

　　3) BMS can repair batteries with poor performance. BMS cannot repair batteries with poor performance. At best, it can slow down its deterioration and suppress its impact.

　　4) Balancing can solve the inconsistency in the battery's own capacity. Charge equalization or discharge equalization alone has no significant improvement effect on capacity differences. Only high current discharge equalization can improve capacity inconsistency.
