Abstract
Official abstract text for this publication.
An electrically-driven vehicle includes a high-capacity battery unit and a high-output battery unit, both of which supply electric power to rotating electric machines, and a charging inlet serving as a charging port of an external power supply. The high-capacity battery unit receives more charge power from the charging inlet than the high-output battery unit and is positioned nearer to the charging inlet than the high-output battery unit is to the charging inlet. In this way, an electric power loss increase caused by a wiring resistance during an external charge can be suppressed in a plug-in type electrically-driven vehicle, which is chargeable by an external power supply.
First claim
Opening claim text (preview).
1 . An electrically-driven vehicle comprising: a rotating electric machine configured to drive the vehicle; a high-capacity battery unit configured to have a relatively high capacity and a high-output battery unit configured to have a relatively high output, both supplying electric power to the rotating electric machine; and a charging inlet configured to serve as a charging port of an external power supply; wherein the high-capacity battery unit is configured to receive more charge power from the charging inlet than the high-output battery unit receives and configured to be positioned nearer to the charging inlet than the high-output battery unit is to the charging inlet. 2 . The electrically-driven vehicle according to claim 1 , wherein among the electric power supplied to the rotating electric machine, a ratio of the electric power supplied from the high-capacity battery unit to the rotating electric machine is configured to be higher than a ratio of the electric power supplied from the high-output battery unit to the rotating electric machine. 3 . The electrically-driven vehicle according to claim 1 , wherein the high-capacity battery unit and the high-output battery unit are enclosed in a single case positioned under a floor panel. 4 . The electrically-driven vehicle according to claim 3 , wherein the electrically-driven vehicle further comprises a cooling fan which supplies cooling air to the high-capacity battery unit, and the cooling fan is positioned under a rear seat of the vehicle. 5 . An electrically-driven vehicle comprising: a rotating electric machine configured to drive the vehicle; a high-capacity battery unit configured to have a relatively high capacity and a high-output battery unit configured to have a relatively high output, both supplying electric power to the rotating electric machine; and a charging inlet configured to serve as a charging port of an external power supply, the charging inlet being connected to the high-capacity battery unit via first power wiring and also to the high-output battery unit via second power wiring; wherein the first power wiring is shorter than the second power wiring. 6 . The electrically-driven vehicle according to claim 5 , wherein among the electric power supplied to the rotating electric machine, a ratio of the electric power supplied from the high-capacity battery unit to the rotating electric machine is configured to be higher than a ratio of the electric power supplied from the high-output battery unit to the rotating electric machine. 7 . The electrically-driven vehicle according to claim 5 , wherein the high-capacity battery unit and the high-output battery unit are enclosed in a single case positioned under a floor panel. 8 . The electrically-driven vehicle according to claim 7 , wherein the electrically-driven vehicle further comprises a cooling fan which supplies cooling air to the high-capacity battery unit, and the cooling fan is positioned under a rear seat of the vehicle.
