Haoduodian Energy Storage Station uses electrochemical cells as energy storage elements to store, convert and release electric energy.
The battery energy storage system (BESS) consists of a battery module of multiple cells through necessary devices (e.g. housings, terminals, interfaces, signs and protective devices), with the state of the cells in the battery module monitored by the battery management system (BMS) and fed back to the upper-level energy management system. The organic combination of battery module and BMS constitutes the energy storage unit in the power station. The BMS in the energy storage unit is responsible for monitoring battery capacity and other information (e.g. temperature, voltage, current and state of charge), optimizing and managing the battery operation state, and providing communication interface and protection for the battery.
