ABSTRACT:
A battery charger includes a temperature detection portion that comes in contact with a battery detachably mounted in a battery pocket and detects its battery temperature, and a charge circuit that controls charge of the battery based on the battery temperature detected by the temperature detection portion. The temperature detection portion includes a heat conduction plate and a temperature sensor. The heat conduction plate includes a pair of upper and lower sandwich plates that sandwich the temperature sensor, and an elastic connection arm that connects the upper and lower sandwich plates at a first end side, and an interlock portion that couples the upper and lower sandwich plates at a second end side opposite to the first end side. The elastic connection arm connects first ends of the upper and lower sandwich plates, and the interlock portion couples second ends of the upper and lower sandwich plates. Thus, the upper and lower sandwich plates sandwich and fasten the temperature sensor.
