A vehicle power device includes a front battery module, a rear battery module, a battery case, and a cooling circuit. The cooling circuit includes a cooling pump, a front battery module cooler, a rear battery module cooler, and cooling internal piping. The battery case houses the front and rear battery modules and the cooling internal piping. Coolant from the cooling pump flows to outside of the battery case via the cooling internal piping. The cooling internal piping includes a branched section and a flow path. The branched section is provided between the front battery module and the rear battery module to branch the flow of the coolant to the front battery module cooler and to the rear battery module cooler. The flow path has one end connected to the branched section and another end passing through to outside of the battery case. |
