Abstract: Disclosed is a battery module. The battery module includes a plurality of batteries, a thermal conduction plate, and a temperature sensing element. The plurality of batteries are arranged in a length direction. The thermal conduction plate is located between the adjacent batteries and fits the batteries. The temperature sensing element is in contact with the thermal conduction plate. In the battery module, the thermal conduction plate fits the batteries. Heat generated by the batteries is transferred to the thermal conduction plate. The temperature sensing element is in contact with the thermal conduction plate to acquire a temperature of the batteries. Because the temperature of the batteries that is acquired by the temperature sensing element via the thermal conduction plate is close to an actual temperature of the batteries, a deviation between the temperature acquired by the temperature sensing element and the actual temperature of the batteries can be reduced.
