<p>Provided is an electrical storage device wherein charging/discharging performance of a single cell is prevented from being deteriorated due to influence of heat which is generated when a voltage is increased. The electrical storage device is provided with a battery module (10) composed of a plurality of unit cells connected in parallel, and a DC-DC converter (20) for converting an output voltage of the battery module (10) into a desired voltage. The single cell which constitutes the battery module (10) is composed of a laminated battery.</p> |
