<p>PROBLEM TO BE SOLVED: To extend the degree of freedom for the mounting layout of a battery by making a battery cell control unit small-sized and thin. SOLUTION: The battery cells 16 are cooled by feeding the cooling air from vent holes 18 of the lower wall of a battery case 17 storing battery cells 16 to vent holes 18 of the upper wall collides with a lower side base 23 serving as the heat radiating plate of a battery cell control unit 21 separately arranged on the upper side of a battery 15 so that the battery cell control unit 21 can be possitively cooled and it can be made small-sized and thin.</p> |
