BMS control method for optimizing energy storage battery cluster

The invention discloses a BMS control method for optimizing an energy storage battery cluster, and relates to the technical field of energy storage battery optimization. According to the invention, the BMS secondary control system is used for firstly detecting the voltage of the battery side, and when the voltage of the battery side reaches a qualified value, the circuit breaker Q1 is allowed to be switched on; after the circuit breaker Q1 is normally switched on, the battery system is used for normally supplying power to the PCS or the direct-current bus; when the battery reaches the standard of a BMS three-level fault point during charging and discharging or self-loss, the BMS two-level control system outputs a circuit breaker opening signal to disconnect the circuit breaker Q1 so as to realize protection of the battery system; after BMS third-level protection, the circuit breaker Q1 is closed manually, and after the circuit breaker Q1 is closed, whether the circuit breaker Q1 needs to be disconnected again
