Abstract
A contactless power transfer system includes a power supply ECU configured to control an inverter to stop power transmission from a power transmission unit when a current generated in the power transmission unit exceeds a predetermined threshold value due to short-circuiting of a power reception coil. The power supply ECU estimates a coupling state between a power transmission coil and the power reception coil, and changes the predetermined threshold value in accordance with the estimated coupling state.
