Claims20
An apparatus comprising:
- a transmission unit configured to transmit inquiry information for inquiring presence or absence of a power receiving request to a plurality of power receiving apparatuses;
- a receiving unit configured to receive response information to the inquiry information from each of the power receiving apparatuses;
- a determination unit configured to determine an end timing at which a response waiting time during which the receiving unit waits for the receiving of the response information based on a receiving situation of the response information within a first time from a transmission timing at which the inquiry information has been transmitted;
- and
- a transmission unit configured to transmit power after a lapse of the end timing.
