Abstract

Provided is a power receiving apparatus including: a contact power receiving unit configured to receive power with use of a wired transfer path via a connecting terminal; a contactless power receiving unit configured to receive power with use of a wireless transfer path via contactless coupling with a power supply apparatus; and a control unit configured to determine whether or not power is receivable by the contact power receiving unit and the contactless power receiving unit to control charging of power supply. According to the above embodiment, in a case where power is receivable by both the contaccless power receiving unit and the contact power receiving unit, the control unit controls a rechargeable battery to be allowed to be charged with power received by the contact power receiving unit, and communication with the power supply apparatus to be allowed via the contactless coupling with the power supply apparatus.

Claims

1. A power receiving apparatus comprising:

a contact power receiving unit configured to receive power with use of a wired transfer path via a connecting terminal;

a contactless power receiving unit configured to receive power with use of a wireless transfer path via contactless coupling with a power supply apparatus; and

a control unit configured to determine whether or not power is receivable by the contact power receiving unit and the contactless power receiving unit to control charging of power supply by the contact power receiving unit and the contactless power receiving unit, wherein

in a case where power is receivable by both the contactless power receiving unit and the contact power receiving unit, the control unit controls a rechargeable battery to be allowed to be charged with power received by the contact power receiving unit, and communication with the power supply apparatus to be allowed via the contactless coupling with the power supply apparatus.

2. The power receiving apparatus according to claim 1, wherein

in a case where power is receivable by both the contactless power receiving unit and the contact power receiving unit, the control unit notifies the power supply apparatus via the contactless coupling with the power supply apparatus, that the contactless coupling with the power supply apparatus is used for communication and that power from the power supply apparatus is not used for charging of the rechargeable battery.

3. The power receiving apparatus according to claim 1, wherein

in a case where power is receivable by both the contactless power receiving unit and the contact power receiving unit, the control unit requests the power supply apparatus to reduce power supplied from the power supply apparatus.

4. The power receiving apparatus according to claim 1, wherein

in the case of bringing a state where power is receivable by both the contactless power receiving unit and the contact power receiving unit into a state where power is not receivable by the contact power receiving unit, a notice is given to the power supply apparatus that the rechargeable battery is charged with power from the power supply apparatus.

5. The power receiving apparatus according to claim 1, wherein

in the case of bringing a state where power is receivable by both the contactless power receiving unit and the contact power receiving unit into a state where power is not receivable by the contact power receiving unit, a request is made to the power supply apparatus that power supplied from the power supply apparatus is increased.

6. A method of controlling a power receiving apparatus including a contact power receiving unit configured to receive power with use of a wired transfer path via a connecting terminal and a contactless power receiving unit configured to receive power with use of a wireless transfer path via contactless coupling with a power supply apparatus, comprising:

a step of determining whether or not power is receivable by the contact power receiving unit and the contactless power receiving unit;

a control step of controlling charging of power supply with the contact power receiving unit and the contactless power receiving unit; and

a step of controlling, in a case where power is receivable by both the contactless power receiving unit and the contact power receiving unit, a rechargeable battery to be allowed to be charged with power received by the contact power receiving unit, and communication with the power supply apparatus to be allowed via the contactless coupling with the power supply apparatus.

7. A recording medium for recording a computer program in order to achieve a method of controlling a power receiving apparatus including a contact power receiving unit configured to receive power with use of a wired transfer path via connecting terminal and a contactless power receiving unit configured to receive power with use of a wireless transfer path via contactless coupling with a power supply apparatus, the method of controlling comprising:

a step of determining whether or not power is receivable by the contact power receiving unit and the contactless power receiving unit;

a control step of controlling charging of power supply by the contact power receiving unit and the contactless power receiving unit; and

a step of controlling, in a case where power is receivable by both the contactless power receiving unit and the contact power receiving unit, a rechargeable battery to be allowed to be charged with power received by the contact power receiving unit, and communication with the power supply apparatus to be allowed via the contactless coupling with the power supply apparatus.
