    Abstract: A vehicle control device is mounted on a vehicle that includes a power receiving device that receives power transmitted in a non-contact manner from a ground-side supply device and a battery that charges the power received by the power receiving device. The drive frequency determined based on the requested power of the side is set as the first drive frequency, and the first drive frequency is transmitted to the supply device using wide area wireless communication. When the inverter included in the supply device is controlled to the first drive frequency, the power receiving device receives the power transmitted in a contactless manner and charges the battery, and the power is transferred before and after changing the inverter drive frequency to the first drive frequency. Feedback control is performed to check whether the transmission efficiency is high.

    Abstract: A wireless power transfer system includes: a supply device that is provided on a road and transfers power; and a vehicle that is equipped with a power reception device and travels on the road, so that the power reception device wirelessly receives power from the supply. Further, the vehicle includes a processor, which determines whether a total number of circuits having an interruption function related to power transfer is two or more in the vehicle and the supply device; and reduces an amount of power to be transferred by the supply device to the vehicle in a case where the total number of the circuits having the interruption function is less than two.

    Abstract: A computing device includes a CPU and a memory. A vehicle travels by consuming first electric power and second electric power. The first electric power is electric power, generation of a unit amount of which causes emission of a first amount of carbon dioxide. The second electric power is electric power, generation of a unit amount of which causes emission of a second amount of carbon dioxide, the second amount being smaller than the first amount. The CPU creates a charging plan based on a first ratio occupied by the second electric power in electric power supplied from a first charging position on a travel route of the vehicle.

    Abstract: A ground power supply apparatus for transmitting power to a vehicle by noncontact has: a plurality of power transmission apparatuses for transmitting power to the vehicle; at least one detection device for detecting a signal emitted from the vehicle using narrow range wireless communication; and a controller for controlling the power transmission apparatuses. The power transmission apparatuses are arranged in a road aligned in a direction of advance of the vehicle. One first detection device is arranged so as to enable detection of the signal at an upstream side from the most upstream power transmission apparatus. The control device controls transmission of power from power transmission apparatuses other than the first power transmission apparatus positioned the most upstream, based on the signal detected by the first detection device and power transmission result information at the power transmission apparatus positioned upstream of that power transmission apparatus.

    Abstract: An information processing apparatus accepts an inquiry about rental of a power feed mat that can supply electric power to a movable body. The power feed mat includes a substrate including a power transmission coil and a functional body that performs at least one function of a plurality of functions. The inquiry includes an instruction to designate the at least one function of the plurality of functions. In the information processing apparatus, association information in which function information is associated with identification information of each of a plurality of power feed mats is stored. The function information indicates which of the plurality of functions the power feed mat performs. The information processing apparatus specifies at least one power feed mat among the plurality of power feed mats based on the accepted inquiry and the association information and provides information based on a result of specifying.
