Abstract

Abstract To minimize temperature differences between batteries and also between battery cells for effectively cooling the batteries uniformly, a fan structure is disposed on one side of a box assembly of a battery box and four of six surfaces of each of the batteries which are box-shaped are covered with thermally insulating members. When a motor of the fan structure is energized, the fan structure introduces cooling air forcibly into the box assembly to cool the two exposed surfaces of each of the batteries. The battery box with the fan structure is relatively simple in structure, lightweight, economical, and can easily be inspected and serviced for maintenance.
