Abstract: The battery pack includes a cell stack and a battery case. The cell stack is formed by stacking a plurality of battery cells having a substantially rectangular parallelepiped shape. The battery case is formed in a substantially rectangular parallelepiped shape and accommodates the cell stack. The battery case includes a first protrusion protruding from an outer surface of the battery case to an outside of the battery case at a position of a gap between adjacent battery cells in a stacking direction of the cell stack.

Abstract: A power storage device includes: a plurality of power storage modules; a pair of frame members extending along a first direction, and disposed to be spaced in a second direction perpendicular to the first direction such that the plurality of power storage modules are located therebetween; a plurality of cross members each connecting the pair of frame members to define a region in which each of the plurality of power storage modules is disposed; and a panel member covering the plurality of power storage modules. The plurality of cross members extend along the second direction and are disposed side by side in the first direction. The panel member includes a plurality of panel constituting members extending along the first direction and disposed side by side in the second direction.

Abstract: A battery case includes: a frame that holds an end portion of a battery in a stacking direction of the battery; a cross member that is disposed so as to extend in the stacking direction of the battery; and a cross bracket that couples the frame and the cross member. The cross bracket includes a base portion that is joined to the frame, and a pair of corner bracket portions that extends from the base portion, that sandwiches a wall portion of the cross member from both sides, and that is joined to the wall portion. A cutout is provided at a site where a surface of each of the pair of corner bracket portions on a side of the wall portion and a surface of the base portion on the side of the wall portion intersect.

Abstract: A battery pack includes a plurality of secondary batteries, and a binding band made of fiber reinforced plastic. The binding band has a braid member formed into a braided state with use of a plurality of bundled bodies, and a reinforcing part made of resin impregnated in the braid member. Each of the bundled bodies includes a plurality of fiber materials that have been bundled together.

Abstract: The wire harness is a wire harness to be mounted on power storage elements and the wire harness includes a base film having flexibility, a cover film covering the base film and having flexibility, and electric wires disposed between the base film and the cover film. The electric wires include first end sections that extend outside the base film and the cover film and second end sections that extend outside from the base film and the cover film from an opposite side from the first end sections. The base film and the cover film include welding portions at which the base film and the cover film are joined with welding.
