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.

A temperature control structure for controlling the temperatures of batteries, comprising: a casing; a plurality of batteries housed in said casing, each of said batteries being of a box shape having six surfaces; thermally insulating members covering four of said six surfaces of each of said batteries and leaving two uninsulated surfaces; air passages defined in said casings, the two uninsulated surfaces of each of said batteries being exposed to said air passages; and means for forcibly applying cooling air through said air passages to the two uninsulated surfaces of each of said batteries.
