PROBLEM TO BE SOLVED: To provide an electric vehicle that continues, by a simple configuration without adding hardware, high efficiency in the charging of a battery by means of non-contact power transmission of AC power transmitted from a power transmission circuit external to the vehicle.SOLUTION: An electric vehicle is configured such that a charging current value I2 can be set by a charging current value setting part 82 according to the voltage Vb of a battery 12. Accordingly, the charging current value I2 can be set according to the voltage Vb of the battery 12 such that the vehicle can be charged in a constant resistance charging mode in which the load resistance value R of a charging circuit has a constant value (R=Vb/I2) at which charging efficiency &eegr; is kept high. |
