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 installed one-to-one correspondence, each of the plurality of slave BMSs includes a slave antenna, and a master BMS including a first master antenna, and configured to wirelessly transmit a trigger signal to the plurality of slave BMSs, the trigger signal for ID allocation to the plurality of slave BMSs. Each slave BMS is configured to generate a response signal including a temporary ID allocated to itself in response to the trigger signal, and wirelessly transmit the response signal to the master BMS. The master BMS is configured to receive the response signal from each of the plurality of slave BMSs through the first master antenna, and determine a formal ID to be allocated to each slave BMS based on a received signal strength of the response signal received through the first master antenna.
