The role is to maintain security and stability.
1. The high and low voltage battery module can monitor the parameters such as voltage and temperature of each battery cell in the battery pack, and realize battery balance management by controlling battery charge and discharge operations to avoid excessive voltage differences between battery cells, thereby prolonging the life of the battery. Battery Life.
2. The high and low voltage battery module can monitor the voltage, current, temperature and other parameters of the battery pack. When the battery pack is abnormal, such as overcharge, over discharge, over temperature, etc., it can cut off the connection between the battery pack and the vehicle in time to protect the battery Group and vehicle safety.
