A wireless battery management system includes a plurality of slave BMSs coupled to a plurality of battery modules in one-to-one correspondence. Each slave BMS is configured to operate in active mode and sleep mode. Each slave BMS is configured to wirelessly transmit a detection signal indicating a state of the battery module. The wireless battery management system further includes a master BMS configured to wirelessly receive the detection signal from each of the plurality of slave BMSs. The master BMS is configured to set a scan cycle and a scan duration for each of the plurality of slave BMSs based on the detection signal, and wirelessly transmit a control signal to the plurality of slave BMSs. The control signal includes a wireless balancing command indicating the scan cycle and the scan duration set for each of the plurality of slave BMSs.
