<P>PROBLEM TO BE SOLVED: To enable jump start without increasing the number of components while enabling charging of both main battery and sub-battery. <P>SOLUTION: A socket 44 receives a charging voltage and auxiliary voltage for the main battery 4 from an external power supply. A charging line Lch connects the charging voltage to the main battery 4. Auxiliary power supply lines L5, L6 connect the auxiliary voltage to a vehicle drive control unit 452. A main switch 9 is provided on a constant line L4 for inputting the output of a power conversion unit 6 to the vehicle drive control unit 452. The vehicle drive control unit 452 includes: a power conversion unit starting unit which is started when the auxiliary voltage is applied and outputs a starting signal ST of the power conversion unit 6; and a means which maintains the starting signal ST to charge the sub-battery 5 with power from the power conversion unit 6 when the voltage applied from the power conversion unit 6 through the main switch 9 to the vehicle drive control unit 452 is a predetermined value. <P>COPYRIGHT: (C)2012,JPO&INPIT |
