HV BMS EHVS500 is a control and management system specially used for series-connected energy storage batteries. This high voltage battery management system mainly consists of three parts: BCU, BMU and power part. Its main function is to manage and control the battery cluster in the series-connected energy storage battery system. Usually, the BMU module in EHVS500 will be placed in the single battery PACK of the high-voltage system, responsible for monitoring and collecting real-time data such as battery voltage and temperature. The BCU module will be placed in the main control box of the high-voltage system to better monitor and manage the status of the battery cluster. The system mainly consists of three parts: BCU, BMU and power part.
High-voltage BMS plays a key role in energy storage systems, ensuring the efficiency and safety of battery storage and release of energy. Whether it is a home energy storage system or a large-scale energy storage system at the grid level, high-voltage BMS can optimize the battery efficiency, extend the battery life, and prevent abnormal conditions such as overcharging, over-discharging, and overheating of the battery by real-time monitoring of battery voltage, current, temperature and other parameters, as well as the remaining capacity (SOC) of the battery.
