Abstract: A battery case includes L-shaped plates. One L-shaped plate is composed of a bottom part and a wall part. The bottom part is located between base ends of support pillar members and a bottom plate and joined to the bottom plate. The wall part is placed against outer lateral surfaces of the support pillar members and mechanically joined to these outer lateral surfaces. Another L-shaped plate is composed of a bottom part and a wall part. The bottom part is located between base ends of support pillar members and the bottom plate and joined to the bottom plate. The wall part is placed against outer lateral surfaces of the support pillar members and mechanically joined to these outer lateral surfaces.

Abstract: A power storage device includes: a power storage module; a housing case having a housing space formed therein and configured to house the power storage module in the housing space; a cooler arranged in the housing case and configured to cool air sent toward the power storage module; a storage portion configured to store condensation water generated as a result of cooling by the cooler; and an air permeable film configured to allow a vapor generated from the condensation water stored in the storage portion to pass therethrough. The storage portion and the air permeable film are provided in a separated space separated from the housing space. The vapor passes through the separated space and reaches the air permeable film.

Abstract: A vehicle includes: a floor panel; and a battery pack mounted under the floor panel. The battery pack includes: a plurality of cell stacks; a housing case including a bottom portion and configured to house the plurality of cell stacks; and a plurality of support members provided on the bottom portion and spaced apart from one another. When a front region, a central region and a rear region are defined in a bottom view of the housing case, a ratio of a total area where the support member is provided in the central region to an area of the central region is higher than a ratio of a total area where the support member is provided in the rear region to an area of the rear region.
