PROBLEM TO BE SOLVED: To provide a technology that can reduce possibility in which a power reception device cannot adequately receive power after non-contact power transmission from a power transmission device to the power reception device is started.SOLUTION: An ECU 140 determines whether or not non-contact power transmission is possible (whether or not power reception by a power reception unit 110 is possible), according to whether or not an above mentioned predetermined parameter (power reception efficiency) is within a predetermined range. And the ECU 140 modifies a predetermined range according to at least one of time required for charging a power storage device 150 and ambient temperature. By means of this vehicle 100, since characteristic change of elements included in the power reception unit 110 and a power transmission unit 210 is considered in determining whether or not the non-contact power transmission is possible, possibility in which the power reception unit 110 cannot adequately receive power after starting the non-contact power transmission can be reduced.SELECTED DRAWING: Figure 1
【課題】送電装置から受電装置への非接触での送電の開始後に、受電装置が十分に受電できなくなる可能性を低減可能な技術を提供する。【解決手段】ECU140は、上述の所定パラメータ(受電効率)が所定範囲内に収まっているか否かに従って、非接触電力伝送の可否(受電部110による受電の可否)を判定する。そして、ECU140は、蓄電装置150の充電に要する時間及び外気温の少なくとも一方に従って上記所定範囲を修正する。この車両100によれば、非接触電力伝送の可否判定において受電部110及び送電部210に含まれる素子の特性変化が考慮されるため、非接触電力伝送の開始後に受電部110が十分に受電できなくなる可能性を低減することができる。【選択図】図1
