Abstract: A battery pack includes a plurality of battery cells, case (housing), circulation path, and blower. The circulation path includes battery paths, inflow side space, outflow side space, and a path along the housing. The battery paths are formed by gaps between adjacent battery cells. The inflow side space distributes fluid to the inlets of the battery paths. The outflow side space gathers fluid from the outlets of the battery paths. The path along the housing is a path that is different from the inflow side space and outflow side space and extends along one or more inner surfaces of the case. The circulation path is formed such that at least one of a flow velocity of the fluid in the inflow side space and a flow velocity of the fluid in the outflow side space is slower than a flow velocity of the fluid in the path along the housing.

Abstract: A battery pack includes a plurality of batteries, a housing, a circulation path, and a blower. The circulation path includes a bottom wall side path formed between lower faces of the batteries and a bottom wall which is the bottom side of the housing. The bottom wall is provided with a plurality of beams arranged in parallel for reinforcing the housing, and the batteries are arranged on the beams. The bottom wall side path is formed as a space surrounded by the lower faces of the batteries, the bottom wall, and the beam. The width of the bottom wall side path formed between adjacent beams is set to be larger than the width of one beam.
