VEHICLE POWER DEVICE

摘要

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.

主权项

1. A vehicle power device comprising:
a front battery module including a plurality of batteries; a rear battery module including a plurality of batteries; a battery case housing the front battery module and the rear battery module; and a cooling circuit including a cooling pump, a front battery module cooler that cools the front battery module, and a rear battery module cooler that cools the rear battery module, the battery case being disposed below a floor panel, the cooling circuit including cooling internal piping that is provided inside the battery case, that receives coolant from the cooling pump, and that discharges coolant to outside of the battery case, and the cooling internal piping including, between the front battery module and the rear battery module, a branched section where the flow of coolant branches to the front battery module cooler and to the rear battery module cooler and including a flow path having one end connected to the branched section and another end passing through to outside the battery case through one side of the battery case in a vehicle width direction.
