Battery management system

A battery management system for managing a battery assembly, the battery management system comprising:

• a management circuit that manages the battery assembly;
• a plurality of monitoring circuits that monitor the battery assembly;
• and
• a setting circuit, wherein
• the management circuit wirelessly transmits, to the plurality of monitoring circuits, a first signal including identification information of one monitoring circuit among the plurality of monitoring circuits,
• each monitoring circuit in the plurality of monitoring circuits includes identification information identifying the monitoring circuit, receives the first signal transmitted by the management circuit, and outputs a second signal on condition that the first signal received matches the identification information, and
• the setting circuit generates and outputs correspondence information that associates (i) position information of the one monitoring circuit, among the plurality of monitoring circuits, that output the second signal with (ii) the identification information included in the first signal transmitted by the management circuit.
