Patent ID: 8836272

Claim:
A vehicle capable of being connected to an external power supply, said vehicle comprising: a load consuming electric power; a first relay; a second relay; a third relay; a first power storage device connected to said load through said first relay and configured such that a plurality of battery modules separately disposed are connected in series through said second relay; a charging device including a capacitor connected to said first power storage device in parallel with said load, and converting electric power supplied from said external power supply into electric power that can be supplied to said first power storage device, said capacitor being connected to said first power storage device through said third relay and connected to said load through said first relay and said third relay; and a control device controlling said first relay, said second relay and said third relay, wherein when charging from said external power supply to said first power storage device is performed, said control device interrupts a discharge path from said charging device to said load by turning off said first relay, and ensures a first charge path from said charging device to said first power storage device by turning on said second relay and said third relay, and when said charging is completed, said control device interrupts said first charge path by turning off said second relay, and ensures said discharge path by turning on said first relay and said third relay, thereby causing electric charge remaining in said capacitor to be discharged through said load.
