Abstract
A power transmission apparatus that transmits power wirelessly to a power receiving apparatus by using power supplied from a power supply apparatus includes a first authentication unit configured to execute device authentication with the power supply apparatus, a second authentication unit configured to execute device authentication with the power receiving apparatus, and a control unit that performs negotiation related to transmission power with the power receiving apparatus based on a result of the device authentication by the first authentication unit and a result of the device authentication by the second authentication unit.
Claims10
A power receiving apparatus comprising:
- a transmission unit configured to transmit a first packet including identification information and a second packet indicating configuration information of the power receiving apparatus, the configuration information including information indicating whether authentication functionality is supported by the power receiving apparatus;
- a negotiation unit configured to negotiate with a power transmission apparatus after receiving an acknowledgment for the second packet from the power transmission apparatus;
- an authentication unit configured to perform processing of authentication in a case where the power transmission apparatus supports the authentication;
- and
- a power receiving unit configured to wirelessly receive power from the power transmission apparatus.
A power receiving method comprising:
- transmitting a first packet including identification information and a second packet indicating configuration information of the power receiving apparatus, the configuration information including information indicating whether authentication functionality is supported by the power receiving apparatus;
- negotiating with a power transmission apparatus after receiving an acknowledgment for the second packet from the power transmission apparatus;
- performing processing of authentication in a case where the power transmission apparatus supports the authentication;
- and
- wirelessly receiving power from the power transmission apparatus.
A non-transitory computer-readable storage medium storing a program for causing a computer to execute a power receiving method comprising:
- transmitting a first packet including identification information and a second packet indicating configuration information of the power receiving apparatus, the configuration information indicating whether authentication functionality is supported by the power receiving apparatus;
- negotiating with a power transmission apparatus after receiving an acknowledgment for the second packet from the power transmission apparatus;
- performing processing of authentication in a case where the power transmission apparatus supports the authentication;
- and
- wirelessly receiving power from the power transmission apparatus.
