Novel BMS power-on wake-up zero-current shutdown circuit

The utility model discloses a novel BMS power-on wake-up zero-current shutdown circuit comprising a battery module, a dormant power supply module, a master control module, a power-on activation module, a charging activation module, and an input switch module and a voltage reduction module which are connected with the positive electrode of the battery module in sequence. The dormancy power supply module is connected between the positive electrode of the battery module and the main control module; the main control module is also connected with the power-on activation module; the power-on activation module and the charging activation module are both connected with the input switch module, and the charging activation module is further connected with the negative electrodes of the power-on activation module and the battery module. According to the utility model, the dormancy power supply module and the master control MCU are additionally arranged, so that the universality and the compatibility of the BMS can be im
