Abstract
In a battery pack including a plurality of prismatic rechargeable batteries arranged in parallel with ventilation spaces being provided therebetween, the battery pack is constituted so that cooling air is downwardly sent from above the battery pack through the ventilation spaces. In accordance with a temperature detected with a temperature detection sensor attached to the lower end of the rechargeable battery, a blower fan is controlled by a control section. Moreover, a sensor placement concave, which is separated from a space inside a battery case through a thin partition wall, is provided on a bottom wall of the battery case of the rechargeable battery. The temperature detection sensor is placed in the sensor placement concave so as to be pressed against the partition wall.
