Specifically, the EMS communicates in real-time with the Battery Management System (BMS), Bidirectional Power Conversion System (PCS), Photovoltaic Inverter, Power Meters, Manageable Load Devices, and Peripheral Devices (Air Conditioning, Fire Protection). It collects critical data from all communication substations, and through data acquisition, processing, and analysis, and internal program logic operations, controls the entire energy storage system to operate in an orderly and robust manner.
[0003] However, the energy management systems used in existing large-scale energy storage systems rely on routers, IO-to-Ethernet devices, CAN-to-Ethernet devices, RS485-to-Ethernet devices, and fire management systems to complete data collection.
