Abstract: A vehicle includes: a controller; a power receiving device that contactlessly receives power from a power transmitting facility; a battery chargeable using the power received by the power receiving device; and a power transmitting device that contactlessly outputs, to another vehicle, the power received by the power receiving device. The other vehicle contactlessly receives power from each of the power transmitting facility and the power transmitting device. When the other vehicle is unable to contactlessly receive the power from the power transmitting facility, the controller controls the power transmitting device to contactlessly output the power received by the power receiving device to the other vehicle in accordance with a request from the other vehicle.
