Abstract

In order to enable smooth sliding by reducing frictional resistance between the upper surface of a heat transfer sheet and the bottom surface of a battery cell while maintaining a heat transfer state between the battery cell and the heat transfer sheet, a power supply device is provided with: a plurality of battery cells (1) each having a square exterior can; a pair of end plates (3) that cover both end surfaces of a battery stack in which the plurality of battery cells (1) are stacked; a plurality of lacing strips which are plate-shaped and extend in the stacking direction of the plurality of battery cells (1), are respectively arranged on the opposite side surfaces of the battery stack, and fasten the end plates (3) to each other; a heat dissipation plate (9) on which the battery stack is placed on the upper surface side and which dissipates heat from the battery stack; and a heat transfer sheet (6) that is interposed between the upper surface of the heat dissipation plate (9) and the lower surface of the battery stack and that causes the heat dissipation plate (9) and the battery stack to be in a thermally coupled state, in which a low-friction sliding layer (7) having a lower frictional resistance than the frictional resistance of the upper surface of the heat transfer sheet (6) is provided between the heat transfer sheet (6) and the battery cells (1).

Description

technical field [0001] The present invention relates to a power supply device, an electric vehicle using the power supply device, and a power storage device. Background technique [0002] The power supply device is used in a power supply device for driving an electric vehicle, a power supply device for storing electricity, and the like. In such a power supply device, a plurality of chargeable and dischargeable battery cells are laminated. In addition, it is known that the outer casing of the battery cell expands due to charging and discharging. Therefore, the battery laminate formed by laminating a plurality of battery cells is fastened and held in a compressed state. Generally speaking, if Figure 9 As shown in the perspective view of , in the power supply device 900 , end plates 903 are arranged on the end surfaces of both sides of the battery stack 910 formed by alternately stacking the battery cells 901 of the rectangular outer can and the insulating spacers 902 . , t...
