1. A battery management system (BMS) managing apparatus including a master BMS and a plurality of slave BMSs, the BMS managing apparatus comprising:
the master BMS configured to send a non-volatile (NV) value confirmation request to the plurality of slave BMSs, and send a uniformization request to the plurality of slave BMSs based on whether a source ID is set, when a response to the NV value confirmation request is received from the plurality of slave BMSs; and
the plurality of slave BMSs configured to send each NV value to the master BMS when the NV value confirmation request is received from the master BMS, set a representative BMS and a target BMS based on the plurality of NV values, set the representative BMS or one of the plurality of slave BMSs corresponding to the source ID as a source BMS according to the uniformization request received from the master BMS, and update an NV value of the target BMS according to an NV value of the source BMS.
