Document Type and Number:
Japanese Patent JP6686922
Kind Code:
B2
Abstract:
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
