Abstract

In order to simplify a structure for insulating battery cells from each other while maintaining the creeping distance between a battery cell and a fastening member and thereby make it possible to effectively prevent shorts through condensation water and the like, a power supply device is provided with: a plurality of battery cells (1) having a rectangular external shape; separators interposed between battery cells (1) while the plurality of battery cells (1) are in a stacked state in order to insulate battery cells (1) that are adjacent to each other; and a fastening member for fastening a battery stack in which the battery cells (1) and the separators are stacked in an alternating manner. The separators are provided with a clamping plate section (20) that is arranged between the facing main surfaces of adjacent battery cells (1). A plate-like bottom surface covering section (23) that protrudes in the stacking direction of the battery cells (1) and that covers the bottom surfaces of the battery cells (1) is provided to both surfaces of the clamping plate section (20) on the lower end of the clamping plate section (20). The bottom surface covering sections (23) of the separators stacked on both surfaces of the battery cells (1) in the power supply device are stacked together on the bottom surfaces of the battery cells (1).

Description

technical field [0001] The present invention relates to a power supply device for large current used as a power supply for driving a motor of a vehicle such as a hybrid vehicle or an electric vehicle, and a vehicle including the power supply device. Background technique [0002] A power supply device in which a plurality of battery cells with a rectangular outer can is stacked is used in vehicle applications and the like. In such a battery cell, since the positive and negative electrode plates and the electrolytic solution are filled in the conductive outer can, the outer can has potential. Therefore, it is necessary to insulate adjacent exterior cans of stacked battery cells from each other. As such an insulating structure, for example, it has been proposed to cover the surface of the battery cell with a shrink tube made of resin (for example, Patent Document 1), or to accommodate the battery cell in a case made of resin, or to insulate the inside of the outer can to make ...
