1. A master battery management system (BMS) included in a battery system in which a plurality of slave BMSs and a master BMS communicate wirelessly, the master BMS comprising:
a receiving unit configured to receive during a transmission period, from each respective slave BMS of the plurality of slave BMSs, (i) data of the respective slave BMS and (ii) data transmission information indicating that another slave BMS other than the respective slave BMS transmitted data to the master BMS, wherein each of the plurality of slave BMSs is configured to transmit data at least once during the transmission period; and
a determination unit configured to:
identify an error between the master BMS and at least one of the plurality of slave BMSs; and
determine a cause of the error based on the data and the data transmission information received from each slave BMS during the transmission period.
