Abstract: The disclosure relates to an output electrode plate and a battery module. The output electrode plate comprises a first metal plate. The first metal plate includes a first region and a second region in a first direction. The first region includes a first overcurrent portion and a second overcurrent portion in a second direction. The second region is connected to the first region. The first overcurrent portion is provided with a through hole which extends in a thickness direction thereof, and a projection of the through hole along the first direction does not exceed a projection of the second region along the first direction in the second direction, and the first metal plate is formed with a minimum overcurrent section at the through hole, such that the minimum overcurrent section is first fused when a current flowing through the first metal plate is greater than a preset current.

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.
