Battery Management System (BMS) is one of the most important components of lithium battery packs, BMS not only monitors the battery voltage, current, temperature and other parameters in real time, but also takes into account the battery charging and discharging process, leakage detection, thermal management, battery equalization management, alarm reminder, SOC calculations, SOH status report and other functions, so that the battery is always in a safe and controlled charging and discharging process, greatly improving the cycle life in the actual use of the battery. The battery is always in a safe and controllable charging and discharging process, which greatly improves the cycle life of the battery in the actual use of the process. Therefore, each BMS manufacturer attaches great importance to BMS R&D, testing, production and other aspects of the inspection.
