Title: BATTERY PACK
Abstract:
In the present invention, a plurality of batteries are disposed at fixed positions in a battery holder such that the difference in battery temperatures is reduced even in cases where the batteries are generating a large amount of heat. Battery insertion portions (4) formed in a partition (5) are provided to a battery holder (2). Batteries (1) are respectively inserted into the battery insertion portions (4) and arranged parallel in multiple levels and columns so as to be in contact with the partition (5) in a thermally joined state. The partition (5) disposed within the battery holder (2) is a heat-insulating dividing partition (5A) obtained by respectively providing opposing partitions (5B) on two sides of an unsealed air layer (6), and the heat-insulating dividing partition (5A) divides the batteries inside the battery holder into two blocks. One surface of each opposing partition (5B) is thermally joined to a corresponding battery (1), and the other surface is exposed to a corresponding air layer (6).
