Abstract

The embodiment of the invention discloses an energy storage system high-voltage box which comprises a box body, and a direct current circuit breaker, a direct current sensor, a contactor and a battery management unit are arranged in the box body. Correspondingly, a wiring terminal, a circuit breaker opening and closing handle and a battery management unit communication interface are installed on a panel of the box body. The direct-current circuit breaker is connected with the wiring terminal, is connected with an external battery pack through the wiring terminal, and uploads the connection or disconnection state of the circuit breaker to the battery management unit; the direct current sensor uploads a current signal to the battery management unit; and the contactor is connected with the wiring terminal, is connected with an external battery pack through the wiring terminal, and uploads the on or off state of the contactor to the battery management unit. The reliability of an electrical main loop of a local battery pack and the performance of a battery management unit can be further improved, and reliable operation of a battery system is guaranteed.
