Abstract
A power receiving device according to the present disclosure includes a power receiving section that receives power from a power feed device with use of a power receiving coil; and a communication section that transmits coil information to the power feed device, the coil information indicating whether or not a coil is provided near the power receiving coil.
Claims17
A power receiving device, comprising:
- a power receiving section configured to receive power from a power feed device with use of a power receiving coil;
- and
- a communication section configured to transmit coil information regarding the power receiving coil to the power feed device, the coil information indicating whether the power receiving device comprises a coil provided near the power receiving coil, wherein the power receiving device comprises the coil which is provided near the power receiving coil and configures a resonant circuit,
- the coil information includes information regarding an impedance of the resonant circuit,
- the communication section is configured to receive response information after transmitting the coil information, the response information indicating whether the power feed device is to supply power to the power receiving section, and
- in a case where the response information indicates that power is to be supplied, the communication section is configured to transmit a request to the power feed device for an increase in feeding power.
