<p><P>PROBLEM TO BE SOLVED: To provide a charger of vehicle which can control the charging power so that "tripping of a breaker" does not take place as much as possible, when charging the power storage device by using a commercial power supply. <P>SOLUTION: AC power supplied from a commercial power supply CP to a vehicle via a power cable 70 is converted into DC power by a charger 20 and supplied to a power storage device 11. Before starting the charging, a PLGECU 50 acquires a rated current value of the power cable 70, and estimates the standard voltage of the commercial power supply CP on the basis of the voltage that has been applied. An ECU 50 sets a value obtained by adding a predetermined value to the product of the rated current value of the power cable 70 and the standard voltage of the commercial power supply CP as an allowable upper limit power Pgrd, and when the real charging power Pact, i.e., the product of the detection current from a current sensor 61 and the detection voltage VB from a voltage sensor 62, exceeds the allowable upper limit power Pgrd, the ECU 50 reduces a power command value CHPW, i.e., the target value of output from the charger 20 used by a charge control circuit 26 immediately. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
