Abstract: A battery pack includes: a cell stack; a first duct and a second duct configured to feed cooling air toward the cell stack; and a housing case. The first duct and the second duct extend in a first direction and are spaced apart from each other in a second direction, the first direction being parallel to a front-back direction of a vehicle in a mounted state in which the battery pack is mounted on the vehicle, the second direction being parallel to a width direction of the vehicle in the mounted state. The first duct is arranged on an outer side of the cell stack on one side in the second direction, and the second duct is arranged on an outer side of the cell stack on the other side in the second direction.

Abstract: A battery pack includes: a plurality of battery modules arranged side by side along a first direction orthogonal to an up-down direction; a housing case configured to house the plurality of battery modules; a wire harness electrically connected to the plurality of battery modules and routed in the housing case; and a reinforcing portion provided within the housing case and configured to reinforce the housing case. The reinforcing portion includes a plate-shaped portion arranged separately from the plurality of battery modules and extending along the first direction. The plate-shaped portion has a lower surface facing the plurality-of-battery-modules side, and an upper surface located on an opposite side of the lower surface. The wire harness is routed along the upper surface of the plate-shaped portion.

Abstract: Each cell forming a battery stack has a discharge valve configured to discharge gas in the inside to the outside when an internal pressure increases. A case houses the battery stack. A plate member is provided between each discharge valve and an upper case. The plate member is arranged to overlap with each discharge valve when the battery stack and the plate member are planarly viewed from above.
