Abstract
A power supply unit capable of simplifying the structure of a battery case and improving the cooling efficiency by increasing the cross sectional area of a coolant passage. A power supply unit includes a battery case; a plurality of battery modules disposed in parallel, each battery module is composed of three cells connected in series in a row, and the front end and the rear end of the battery module are held by the front part and the rear part of the battery case; a cooling fan for forcing a cooling air to flow in the passage between the neighboring battery modules; a shielding plate for shielding the cooling air from the battery module, which is placed at the upstream side of the passage and; a rectifying fin for increasing the flow rate of the cooling air, which is placed at the downstream side of the passage.
