<p><P>PROBLEM TO BE SOLVED: To make possible both the improvement of charging efficiency and the obtainment of operation of auxiliary load systems at the time of external charging, in an electric vehicle on which a storage device chargeable by an external power source is mounted. <P>SOLUTION: A charging route of a main battery 10 by an external charging power source 400 is formed by turning on relays 150A, 150B. This charging route is provided so as to be independent from a conduction route between a motor generator 30 for generating a driving force of a vehicle and the main battery 10 formed by turning on a relay 150C. Furthermore, operation electric power is supplied from power supply wirings 151 between the relay 150B and a power converter 110 to the auxiliary load systems including an auxiliary battery 70 without being connected to the conduction route so that the systems can operate even when the relay 150C is turned off. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
