Abstract

An electronic device includes a power receiving unit that wirelessly receives power from a power supply apparatus; a first communication unit that performs wireless communication; a connection unit that connects a communication device including a second communication unit that performs wireless communication; and a control unit that (a) determines whether the communication device is capable of receiving predetermined power if the communication device is connected with the connection unit, and (b) controls the first communication unit to transmit data for notifying the power supply apparatus about a presence of a device which is not capable of using wireless power supply if the communication device is not capable of receiving the predetermined power.

Claims

1. An electronic device comprising:

a power receiving unit that wirelessly receives power from a power supply apparatus;

a first communication unit that performs wireless communication;

a connection unit that connects a communication device including a second communication unit that performs wireless communication; and

a control unit that (a) determines whether the communication device is capable of receiving predetermined power if the communication device and the connection unit are connected, and (b) controls the first communication unit to transmit data for notifying the power supply apparatus about a presence of a device which is not capable of using wireless power supply if the communication device is not capable of receiving the predetermined power.

2. The electronic device according to claim 1, wherein if the communication device is not capable of receiving the predetermined power, the control unit causes a display device to display information for notifying that wireless power supply does not be performed from the power supply apparatus to the electronic device.

3. The electronic device according to claim 1, wherein if the communication device is not capable of receiving the predetermined power, the control unit causes a display device to display information for notifying that the communication device is removed from the electronic device.

4. The electronic device according to claim 1, wherein a communication protocol of the first communication unit corresponds to a protocol of the second communication unit.

5. The electronic device according to claim 1, wherein the predetermined power is higher than communication power used for performing wireless communication.

6. The electronic device according to claim 1, wherein a communication protocol of the first communication unit conforms to NFC (near field communication) standard.

7. The electronic device according to claim 1, wherein if the communication device and the connection unit are connected, the control unit obtains data relating to the communication device from the communication device, and

wherein the control unit determines whether the communication device is capable of receiving the predetermined power, using the data relating to the communication device.

8. The electronic device according to claim 1, wherein the communication device is capable of performing a predetermined authentication using the second communication unit.

9. The electronic device according to claim 1, wherein the communication device is capable of performing an electronic payment using the second communication unit.

10. The electronic device according to claim 1, wherein the communication device is capable of acting as at least one of a memory card and a SIM (subscriber identity module) card.

11. The electronic device according to claim 1, the power supply apparatus includes:

a power supply unit that wirelessly supplies power;

a communication unit that performs wireless communication with the electronic device; and

a control unit that performs a process of limiting wireless power supply to the electronic device if the communication unit receives data for notifying the power supply apparatus about a presence of a device which is not capable of using wireless power supply.

12. A method of controlling an electronic device comprising:

determining whether a communication device is capable of receiving predetermined power if the communication device is connected with a connection unit of the electronic device, wherein the electronic device includes a power receiving unit that wirelessly receives power from a power supply apparatus, a first communication unit that performs wireless communication, and the connection unit that connects the communication device including a second communication unit that performs wireless communication; and

controlling the first communication unit to transmit data for notifying the power supply apparatus about a presence of a device which is not capable of using wireless power supply if the communication device is not capable of receiving the predetermined power.

13. A non-transitory storage medium that stores a program for causing a computer to perform a method of controlling an electronic device, the method comprising:

determining whether a communication device is capable of receiving predetermined power if the communication device is connected with a connection unit of the electronic device, wherein the electronic device includes a power receiving unit that wirelessly receives power from a power supply apparatus, a first communication unit that performs wireless communication, and the connection unit that connects the communication device including a second communication unit that performs wireless communication; and

controlling the first communication unit to transmit data for notifying the power supply apparatus about a presence of a device which is not capable of using wireless power supply if the communication device is not capable of receiving the predetermined power.

14. A power supply apparatus comprising:

a power supply unit that wirelessly supplies power to an electronic device;

a communication unit that performs wireless communication with the electronic device; and

a control unit that performs a process of limiting wireless power supply to the electronic device if the communication unit receives data for notifying the power supply apparatus about a presence of a device which is not capable of using wireless power supply.

15. The power supply apparatus according to claim 14, wherein the data for notifying the power supply apparatus about a presence of a device which is not capable of using wireless power supply corresponds to data indicating that a presence of the device which is not capable of receiving predetermined power is detected by the electronic device.

16. The power supply apparatus according to claim 15, wherein the predetermined power is higher than communication power used for performing the wireless communication.

17. The power supply apparatus according to claim 14, wherein the control unit performs a process of notifying about limiting wireless power supply if the communication unit receives data for notifying the power supply apparatus about a presence of a device which is not capable of using wireless power supply.

18. The power supply apparatus according to claim 14, wherein a communication protocol of the communication unit conforms to NFC (near field communication) standard.

19. A method of controlling a power supply apparatus comprising:

wirelessly supplying power to an electronic device;

causing a communication unit to perform wireless communication with the electronic device; and

performing a process of limiting wireless power supply to the electronic device if the communication unit receives data for notifying the power supply apparatus about a presence of a device which is not capable of using wireless power supply.

20. A non-transitory storage medium that stores a program for causing a computer to perform a method of controlling a power supply apparatus, the method comprising:

wirelessly supplying power to an electronic device;

causing a communication unit to perform wireless communication with the electronic device; and
