Abstract
A power supply ECU executes a control process including: when it is determined that wireless charging is being performed, a step of acquiring a current Iand a voltage Vduring power transmission operation; when it is determined that the power transmission operation is being performed and the power cannot be received, a step of determining whether or not a value of V/Iis greater than a threshold value R; when it is determined that the value of V/Iis greater than threshold value R, a step of determining that a power transmission coil has been short-circuited; and when it is determined that the value of V/Iis smaller than or equal to threshold value R, a step of determining that a power reception coil has been short-circuited.
