PROBLEM TO BE SOLVED: To detect an OFF failure of a charging relay more properly and let users be aware thereof.SOLUTION: A vehicle ECU, when a communication with a transmission ECU is normal (S170), outputs an ON command to a charging relay (S210), then compares a voltage difference ΔV2, when power is being supplied to a resonance circuit for power transmission, between an inter-terminal voltage Vtr of the resonance circuit for power transmission and an inter-terminal voltage Vre2 on the input side (on a charging circuit side of the charging relay) of a charging circuit to a threshold value ΔVref2 (S220 to S240). When the voltage difference ΔV2 is equal to or less than the threshold value ΔVref2, the vehicle ECU determines the charging relay is normal (S250), and when the voltage difference ΔV2 is greater than the threshold value ΔVref2, determines the charging relay is being in an OFF failure, and then performs a display output in a display as such.SELECTED DRAWING: Figure 3 |
