[0045] The PCS (Power Conversion System) converts DC to AC and controls the charging and discharging process of the energy storage system. Implementation involves a high-efficiency bidirectional converter supporting high power density and high conversion efficiency; the PCS's charging and discharging strategy is controlled by the EMS (Energy Management System) to optimize system operation.

[0046] External gateway meters are used for energy metering and data exchange with the external power grid or load.

[0100] Another DC24V power supply branch of the third power supply circuit 112 can supply power to the switch 17 through the circuit breaker 16-2QF2. The 18-XT5 terminal of the switch can perform signal or data interaction with the battery system, display and control and external devices 20, and transmit data or signals to the controller 1012.

[0101] This application also provides an integrated energy storage unit 10, which is equipped with the control device described in any of the preceding claims, and the control device is a detachable device in the integrated energy storage unit 10.
