Abstract
A contactless power transfer system includes a power transmission device and a power receiving device. A second electronic control unit of the power transmission device is configured to determine whether a series of manipulations including severing connection between the power transmission device and the power supply via the power supply cable, and then connecting the power transmission device with the power supply again via the power supply cable, are performed. The second electronic control unit is configured to send a predetermined signal to the power receiving device when the second electronic control unit determines that the series of manipulations are performed. A first electronic control unit of the power receiving device is configured to generate a command for start of power transmission to the power transmission device, irrespective of the time schedule, when the first electronic control unit receives the signal.
