Abstract: A vehicle includes a battery, an electric power acquirer, a power supply unit, first and second relays, and a controller. The electric power acquirer acquires charging electric power from outside. The power supply unit is able to provide a power supply from the battery to a device other than a traveling motor. The first relay connects and disconnects the battery to and from a power supply line. The second relay connects and disconnects the electric power acquirer to and from the power supply line. The controller changes a switching procedure of the first relay and the second relay, in accordance with a state of use of the power supply unit, at an end of charging of the battery through the electric power acquirer.

Abstract: A vehicle includes a battery, an electric power acquirer, a power supply unit, first and second relays, a charging controller, and a first notification processor. The first relay connects the battery to a power supply line or disconnects the battery from the power supply line. The charging controller switches, on a request for charging of the battery with the first relay in a connected state, the first relay to a disconnected state, brings the second relay to a connected state, and switches the first relay to a connected state to start the charging of the battery. The first notification processor gives, on the request for the charging of the battery, a user a notification of temporary shutdown of the power supply unit at a start of the charging of the battery.

Abstract: A vehicle includes a battery, an electric power acquirer, a power supply unit, first and second relays, a controller, a vehicle controller, and a first determination unit. The first determination unit makes a determination, at a system start-up, as to whether or not a power receiving coil of the electric power acquirer is in position to be available for electric power reception from a power transmitting coil of ground facilities. The controller changes, at the system start-up, a switching procedure of the first relay and the second relay on the basis of a result of the determination of the first determination unit.

Abstract: An electric vehicle includes a power receiver, a controller, an error detector, and a record processor. The power receiver wirelessly receives electric power from power transmission equipment disposed outside the vehicle. The controller controls the reception of the electric power via the power receiver. The error detector detects an error in power transmission from the power transmission equipment to the power receiver during the control of the reception of the electric power by the controller. The record processor records error history information regarding the error detected by the error detector and causes a data volume of the error history information retrievable from the record processor to be smaller when the error is due to a foreign object present between the power transmission equipment and the vehicle than when the error is not due to the foreign object.

Abstract: A vehicle includes a battery, an electric power acquirer, a power supply unit, first and second relays, and a controller. The first relay connects and disconnects the battery to and from a power supply line. The second relay connects and disconnects the electric power acquirer to and from the power supply line. The controller executes a first switching control including switching the second relay to a connected state with the first relay kept in a connected state. In the switching of the second relay to the connected state in the first switching control, the controller reduces a difference between a potential of the second relay on the side on which the electric power acquirer is disposed and a potential of the second relay on the side on which the battery is disposed, using electric power inputted from the electric power acquirer.

Abstract: An electric vehicle 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.
