The energy storage cabinet is officially called the integrated cabinet for electrochemical energy storage system. It is based on lithium-ion batteries as the core, integrating battery clusters, battery management system (BMS), energy storage converter (PCS), energy management system (EMS), temperature control system, fire protection system, and power distribution unit. It is a standardized energy storage device that mainly realizes functions such as electricity storage, peak shaving and valley filling, demand response, backup power supply, photovoltaic integration, and grid frequency regulation and phase adjustment. It is widely applied in industrial power distribution, industrial parks, data centers, photovoltaic power stations, microgrids, and new power systems, etc.
