ELECTRICALLY POWERED VEHICLE
First Claim
1. An electrically powered vehicle having mounted thereon a power storage device that can be charged from an external power source, comprising:
- a charging connector for receiving supplied electric power from said external power source during external charging of charging said power storage device from said external power source;
a power converter for converting the supplied electric power from said external power source into charging power for said power storage device;
a power control unit connected between said power storage device and an electric motor for generating a vehicle driving force and configured to control driving of said electric motor;
a first switch interposed into and connected to an electric path between said charging connector and said power converter;
a second switch interposed into and connected to an electric path between said power converter and said power storage device; and
an auxiliary load system arranged to receive electric power through a first line electrically connecting said second switch and said power converter.

Abstract
A path for charging a main battery from an external power source is established by turning on a first relay and a second relay. This charging path is provided independently of an electric path between a motor generator for generating a vehicle driving force and the main battery established by turning on a third relay. Further, an auxiliary load system including an auxiliary battery is not connected to the above-mentioned electric path, but receives operating power through a power line between the second relay and a power converter so as to be operable even with the third relay turned off.
