CROSS-REFERENCE TO RELATED APPLICATIONS

The present application claims priority from Japanese Patent Application No. 2019-132343 filed on Jul. 18, 2019, the entire contents of which are hereby incorporated by reference.

BACKGROUND

The disclosure relates to an electric vehicle and a charge control apparatus for an electric vehicle.

There is a technique of wirelessly transmitting electric power from a power transmitter of ground equipment to a power receiver of an electric vehicle, to charge a battery provided in the electric vehicle with the received electric power. Such a charging mode is referred to as “wireless charging”. Japanese Unexamined Patent Application Publication No. 2013-223397 discloses a technique of stopping the wireless charging in a case where a foreign object is present near the electric power transmitter during the wireless charging, and thereafter restarting the wireless charging in a case where the foreign object is removed.

SUMMARY

An aspect of the technology provides an electric vehicle that includes a power receiver and a controller. The power receiver is configured to wirelessly receive electric power from power transmission equipment disposed outside the vehicle. The controller is configured to control power transmission from the power transmission equipment to the power receiver. The controller includes a determination processor and a frequency control unit. The determination processor is configured to make a determination, in a case where the power transmission is stopped due to a foreign object present between the power transmission equipment and the vehicle, as to whether the power transmission is restartable with a predetermined frequency after the power transmission is stopped. The frequency control unit is configured to change the frequency with which the determination processor makes the determination.

An aspect of the technology provides a charge control apparatus for an electric vehicle. The charge control apparatus includes a power receiver and circuitry. The power receiver is configured to wirelessly receive electric power from a power transmission equipment disposed outside the vehicle. The power receiver is configured to charge a battery with the received electric power. The circuitry is configured to control power transmission from the power transmission equipment to the power receiver. The circuitry is configured to make a determination, in a case where the power transmission is stopped due to a foreign object present between the power transmission equipment and the vehicle, as to whether the power transmission is restartable with a predetermined frequency after the power transmission is stopped. The circuitry is configured to change the frequency of making the determination.
