5-4 Energy storage system 5. New Energy Power System 5.1.2 Introduction to structure and principle BMS controller BMS is used to take control of the battery pack, including battery safety, SOC algorithm, charge and discharge control commands, parameter monitoring, etc. BMS detects the total voltage, total current, cell voltage, temperature and other information of the battery pack, and sends this information to CAN network. BMS performs equalization control of the battery pack to ensure proper working of the battery pack. BMS can carry out thermal management of the battery pack, including heating and cooling control.
Total positive and negative relays The relay connects or disconnects the battery pack power circuit and check the relay contacts for sticking. Battery pack control BMS checks the charging and discharging status of the battery pack, and calculates the battery pack power status. It also controls the charging and discharging status and calculates the power of the battery pack. The battery pack enables the vehicle to drive, accelerate and decelerate by means of charging and discharging. The battery pack sensor detects signals such as voltage, current, and temperature, and transmits the signals to VCU. The battery pack has an insulation detection function. VOYAH FREE
