Abstract
A power feeding unit includes: a power feeding electrode configured to be coupled through an electric field with a power receiving electrode of a power receiving unit; a power feeding section configured to feed the power receiving unit with power through the power feeding electrode; and a power feeding side communication section configured to communicate with the power receiving unit through the power feeding electrode.
Claims13
A power receiving device comprising:
- first filter circuitry electrically connected to power receiving electrodes, the power receiving electrodes are configured to receive an electromagnetic signal wirelessly from a power feeding device;
- power receiving circuitry electrically connected to the first filter circuitry, the first filter circuitry is configured to permit the electromagnetic signal to reach the power receiving circuitry while inhibiting an instruction from reaching the power receiving circuitry;
- second filter circuitry electrically connected to the power receiving electrodes, the power receiving electrodes are configured to receive the instruction wirelessly from the power feeding device;
- and
- communication circuitry electrically connected to the second filter circuitry, the second filter circuitry is configured to permit the instruction to reach the communication circuitry while inhibiting the electromagnetic signal from reaching the communication circuitry,
- wherein the power receiving device is configured to output, from the communication circuitry via the power receiving electrodes when the power receiving electrodes receives the instruction, identification data that permits the power feeding device to identify the power receiving device.
