Disclosed are a wireless battery management system and a battery pack including the same. The 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 using power supplied from the battery module to which the slave BMS is coupled. Each slave BMS is configured to wirelessly transmit a detection signal indicating a state of the battery module to which the slave BMS is coupled in the active mode. 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.
