POWER RECEPTION APPARATUS, DETERMINATION METHOD, AND PROGRAM
First Claim
1. A power reception apparatus comprising:
- a power reception unit configured to receive power wirelessly supplied from a power transmission apparatus;
a voltage conversion unit configured to convert the voltage of the power receive by the power reception unit to a voltage with a particular value;
a load unit configured to operate with an output from the voltage conversion unit;
a first detection unit configured to detect a voltage or a current input to the voltage conversion unit;
a second detection unit configured to detect consumption power of the load unit; and
a determination unit configured to make a determination, based on a result of a detection performed by the first detection unit and a result of a detection performed by the second detection unit, as to whether there exists a foreign object, which is not a target object to which power is to be transmitted, in a power transmission service area covered by the power transmission apparatus.

9. A determination method comprising:
-
performing a first detection process to detect the voltage or the current associated with power as of when the voltage or the current associated with power wirelessly supplied from a power transmission apparatus and received by a power reception apparatus is converted to a voltage with a particular value; performing a second detection process to detect consumption power of a load unit operating using power with the voltage converted to the particular value; and making a determination, based on a result of the detection performed in the first detection process and a result of the detection performed in the second detection process, as to whether there exists a foreign object, which is not a target object to which power is to be transmitted, in a power transmission service area covered by the power transmission apparatus.

11. A power transmission apparatus comprising:
-
a power transmission unit configured to transmit power wirelessly to a power reception apparatus; a first detection unit configured to detect a voltage or a current associated with power as of when a voltage or a current associated with power wirelessly transmitted from the power transmission unit and received by the power reception apparatus is converted to a voltage with a particular value; a second detection unit configured to detect a change in consumption power of a load unit operating using power with the voltage converted to the particular value; determination unit configured to make a determination, based on a result of a detection performed by the first detection unit and a result of a detection performed by the second detection unit, as to whether there exists a foreign object, which is not a target object to which power is to be transmitted, in a power transmission service area covered by the power transmission apparatus.
