Abstract: The energy storage system includes battery cells, a subrack, a backplane, and a battery management system BMS. The subrack reserves a plurality of battery cell slots, the battery cells are connected to the backplane through the battery cell slots. The backplane is installed in the subrack, a first power terminal is reserved at a position corresponding to the battery cell slot on the backplane, and a plug-in power terminal is formed by a second power terminal of the battery cell together with the first power terminal. A power circuit, a sampling circuit, and an equalizer circuit are integrated into the backplane, and the power circuit, the sampling circuit, and the equalizer circuit are connected after the second power terminal is plugged and docked with the first power terminal. The BMS is connected to the backplane for managing the energy storage system.

Abstract: A miniature circuit breaker, a control method thereof, and a control system thereof, where the miniature circuit breaker includes a circuit breaker body and a current detection unit. The circuit breaker body and the current detection unit are located in respectively independent cavities in the circuit breaker and are electrically coupled to each other. After a current that flows from one end of the circuit breaker body flows through the current detection unit, the current flows into another end of the circuit breaker body. The current detection unit includes a voltage drop detection assembly and a signal output terminal. The voltage drop detection assembly includes a first voltage sampling point and a second voltage sampling point, where the first voltage sampling point and the second voltage sampling point are coupled to the signal output terminal.
