摘要： A power relay device may be mounted to a cover which covers a portable power reception device, and may comprise: a coil; a power reception circuit which rectifies a power signal received from a power transmission device through the coil; a wireless communication circuit which is driven using the power signal received from the power reception circuit and communicates with the power transmission device and the power reception device by using the coil; and a relay control circuit which is driven using the power signal received from the power reception circuit and is electrically connected to the power reception circuit and the wireless communication circuit. The relay control circuit may be configured to: receive a first received power value indicating power consumed by the power reception device from the wireless communication circuit; and on the basis that the first received power value is received, transmit a second received power value indicating power consumed by the power relay device to the power transmission device by using the wireless communication circuit.

摘要： A power feed system according to the present disclosure includes a power feed device and a power receiving device. The power receiving device includes a power receiving section that receives power wirelessly from the power feed device with use of a power receiving coil, and a first communication section that transmits, to the power feed device, coil information indicating whether or not a coil is provided near the power receiving coil. The power feed device includes a power feed section that supplies power wirelessly to the power receiving device, a second communication section that receives the coil information, and a controller that performs, on the basis of the coil information, a first determination as to whether or not to supply power to the power receiving device, and controls an operation of the power feed section on the basis of a result of the first determination.

摘要： An electrode unit is used in a power transmitting device or a power receiving device of a wireless power transmission system based on an electric field coupling method. The electrode unit includes: a first electrode to which a first voltage is applied when power is transferred; a second electrode to which a second voltage antiphase to the first voltage is applied when power is transferred; and a third electrode spaced apart from the first and second electrodes, the third electrode having a third voltage whose amplitude is less than amplitudes of the first and second voltages when power is transferred. The first and second electrodes are arranged along an electrode installation plane. At least a portion of the third electrode does not overlap the first and second electrodes as viewed from a direction perpendicular to the electrode installation plane.

摘要： In an example, an integrated circuit includes a communication and control unit. The communication and control unit controls an inverter that applies an alternating current output signal to a transmission coil for reception by a receiver. The communication and control unit causes the inverter to provide a first and second transmit powers to the transmission coil, and the communication unit receives a first and second power received signals from the receiver in response to the first and second transmit powers. The communication and control unit determines a first gain and offset using the first transmit power, the first power. When a third transmit power greater than the second transmit power is transmitted by the transmission coil, the communication and control unit determines a second gain and a second offset using the first transmit power, the first power received signal, the third transmit power and a third power received signal.
