Abstract
A power transmitting apparatus performs detection processing for detecting an object different from a power receiving apparatus, and performs processing for a parameter used in the detection processing based on a voltage change of a voltage applied to a transmitting unit.
Claims11
A power receiving apparatus, comprising:
- a power receiving unit that wirelessly receives power from a power transmitting apparatus;
- a communication unit that communicates with the power transmitting apparatus;
- and
- a changing unit that changes a voltage,
- wherein
- the communication unit transmits a first received power packet including information indicating a first received power value, to the power transmitting apparatus,
- the changing unit changes, after the first received power packet is transmitted, a voltage of the power receiving apparatus based on an authentication to the power transmitting apparatus, and
- the communication unit transmits, after the first received power packet is transmitted and after the voltage of the power receiving apparatus is changed, a second received power packet including information indicating a second received power value, and a third received power packet including information indicating a third received power value, to the power transmitting apparatus.
