POWER RECEIVING APPARATUS AND POWER RECEIVING METHOD
First Claim
1. A power receiving apparatus capable of receiving power by wireless power supply using magnetic field resonance of a resonant element, comprising:
- an execution unit configured to execute a predetermined operation using the power received by the resonant element; and
a selection unit configured to, based on a state of the power receiving apparatus about the predetermined operation executed by said execution unit, make a selection as to whether the resonant element operates as a power receiving element to receive power or a relay element to perform magnetic field relay to another apparatus.

Abstract
Even in a case where a power receiving apparatus during wireless power supply is connected to an AC power supply or an apparatus cannot be immediately used after charging due to the occurrence of an error, if wireless power supply is performed, such wireless power supply is inefficient. An embodiment of this invention is made to solve this drawback. Depending on the presence/absence of the connection between the power receiving apparatus and the AC power supply, or depending on an error state of the power receiving apparatus, charging or relay of power from the power transmission apparatus is changed over. This makes it possible to efficiently supply power from the power transmission apparatus depending on the state of the power receiving apparatus.
