Battery temperature unevenness suppressing power supply
A power supply device is provided that includes a battery module (3) and a cooling mechanism. The battery module is composed of a plurality of batteries (20) arranged side by side. The cooling mechanism cools the batteries (20). A thermally-insulating member (70) is arranged on a part of a battery module surface, and thermally insulates heat generated from the batteries. This power supply device can reduce the temperature unevenness ΔT.
