Abstract: A power supply device includes battery cells each having a rectangular external shape, a separator disposed between the battery cells, a pair of end plates that are disposed on respective ends of a battery assembly in which the separator and the battery cells are stacked, and a bind bar that binds the pair of end plates. The separator has insulating rib parts that protrude from both surfaces of the separator, and the insulating rib parts of the separator stacked on each surface of the battery cell are stacked on each other on a bottom surface of the battery cell. The insulating rib parts are stacked on each other on the bottom surface of the battery cell by inserting an insertion rib provided in one of the stacked insulating rib parts into an insertion groove provided in the other of the stacked insulating rib parts.

Abstract: A vehicular power source device includes: a case incorporating a battery; a service plug coupled to the battery incorporated in the case; and a protection cover of the service plug. The protection cover includes: a covering portion of the service plug; a fixing board fixed to the case via a fastener; and an opening board disposed to be adjacent to the fixing board and providing a gap to the case. In addition, the fixing board includes: a fixing portion fixed onto the case via the fastener; a linking portion linking the fixing portion to the covering portion; and a breaking portion. The breaking portion is provided in the fixing portion or in a boundary portion between the fixing portion and the linking portion, and a breaking strength of the breaking portion is lower than that of the linking portion.
