High-voltage energy storage battery management system is mainly used in household energy storage, commercial energy storage and other applications, this system is a distributed two-level framework energy storage system, the system is mainly divided into battery management master control unit(BCMU), battery management unit (BMU). The system can detect the single cell voltage, cell temperature, current, total voltage and other data in real time, calculate the remaining capacity SOC in real time, predict the battery monitoring status SOH, estimate the current cell power status SOP, effectively manage the safety of lithium battery system, and realize the information interaction with PCS through CAN/RS485 communication interface.

The system single group maximum 8 battery module + master control module composed of 80kWh, 40KW power output of the energy storage system, distributed with multiple battery systems, to build a larger power demand and power use, support for mainstream high-voltage hybrid inverter protocol communication.
