Abstract
An electric power source device has multiple layered battery cells which are electrically connected in series and/or in parallel. The battery cells are accommodated in a battery casing, which has a heat insulating structure at a portion surrounding the battery cells. The power source device further has a heating unit between lower surfaces of the battery cells and a bottom plate of the battery casing. A heat storage layer is further provided between the heating unit and the bottom plate for storing the heat generated at the heating unit.
