Abstract: An assembled battery is formed by combining battery modules. Each battery module includes at least one battery cell and a rectangular box-shaped case that accommodates the at least one battery cell. The battery modules include a first battery module and a second battery module located adjacent to each other. The case of each of the first battery module and the second battery module includes an opposing side surface that is opposed to one of the first battery module and the second battery module. Each opposing side surface includes projections, which are laid out in rows, and ribs, which extend parallel to the layout direction of the projections. The ribs are smaller in height than the first projections. The ribs include connection ribs that connect the projections located in a predetermined range in the layout direction of the projections.

Abstract: The present specification discloses a technology for protecting a portion where corrosion may occur in the assembled battery. An assembled battery includes a plurality of battery packs. Each of the battery packs includes a housing with an opening at a top thereof, a cover plate, and a relief valve. The cover plate is welded at the opening which seals the housing. The relief valve is provided on the cover plate. The assembled battery hardier includes an exhaust cover and an insulating sheet. The exhaust cover covers the relief valve of each of the battery packs, and guides, toward the outside of the assembled battery, an internal gas that comes out of the relief valves. The insulating sheet may cover a portion of a welded line between the housing and the cover plate of each battery pack, and the portion faces the exhaust cover.
