Abstract:
A battery module (26) includes a stacked body (31) that is electrically connected to a power control unit (3) and includes a plurality of battery cell (30), a restraint (32) that restrains the stacked body (31), and includes a metal band (81, 83) made of metal that extends from one end of the stacked body (31) to the other end of the stacked body (31) and is electrically grounded; a voltage sensor (33) that is provided on at least a portion of the plurality of battery cells (30), and detects a voltage of the portion of the plurality of battery cells (30); a first wire (34A, 34B) that is connected to the voltage sensor (33) and extends in a stacking direction of the battery cells (30); a temperature sensor (35, 36) that measures a temperature of the stacked body (31) or a current sensor (20) that measures a current that flows into and out of the stacked body (31); and a second wire (37, 38, 48) that is connected to the temperature sensor (35, 36) or the current sensor (20), and extends in the stacking direction. A voltage lower than that of the first wire (34A, 34B) is applied to the second wire (37, 38, 48), and the metal band (81, 83) is arranged between the first wire (34A, 34B) and the second wire (37, 38, 48).
