1. A battery pack comprising:
a case accommodating a plurality of battery cells; and
a battery management system (BMS) configured to detect damage to the case,
wherein the BMS comprises:
a voltage output terminal configured to output a predetermined voltage;
a ground terminal; and
a voltage measurement terminal configured to measure voltage,
wherein the case comprises:
a conductive member having a first end connected to the voltage output terminal of the BMS and a second end connected to the ground terminal of the BMS; and
a sensing wire having a first end connected to the conductive member and a second end connected to a voltage measurement terminal of the BMS, and
wherein the conductive member is provided between a first surface inside the case and a second surface opposite to the first surface.
