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.
