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.

Abstract: A charging apparatus includes: a first conversion circuit that converts alternating-current power supplied from an external power supply into direct-current power; a second conversion circuit that converts an output voltage from the first conversion circuit into a voltage for a battery and supplies the voltage to the battery; and a controller configured to change charging power to be supplied to the battery by controlling the first conversion circuit and the second conversion circuit when the output voltage falls outside a predetermined reference range, and to determine whether the output voltage in the changed charging power falls within the reference range. When the output voltage falls outside the reference range, the controller controls the first conversion circuit and the second conversion circuit such that the charging power decreases stepwise until the output voltage falls within the reference range.

Abstract: A vehicle configured such that an on-board battery is chargeable by receiving electric power from a power supply outside the vehicle includes an inlet, a voltage sensor that detects an input voltage that is a voltage input from the power supply to the inlet, and a control device configured to execute a detection process when connected to the inlet. The detection process includes a first process that suspends charging when a difference between the input voltage before a start of the charging and the input voltage after the start of the charging is equal to or larger than a threshold value, and a second process that stops the charging when a difference between the input voltage during suspension of the charging in the first process and the input voltage after resumption of the charging is equal to or larger than the threshold value.
