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 receiver that wirelessly receives power from a power supply apparatus;

a first communicator;

a connection interface that connects a detachable communication device to the electronic device, wherein the detachable communication device includes a second communicator that performs wireless communication; and

a CPU that (a) determines whether the detachable communication device that is currently connected is capable of using a wireless power supply from the power supply apparatus, if the detachable communication device and the connection interface are connected, and (b) controls the first communicator to transmit data for notifying the power supply apparatus that the detachable communication device that is currently connected is not capable of using the wireless power supply if the detachable communication device that is currently connected is not capable of using the wireless power supply.

2. The electronic device according to claim 1, wherein if the detachable communication device that is currently connected is not capable of using the wireless power supply, the CPU causes a display device to display information for notifying that the wireless power supply is not performed.

3. The electronic device according to claim 1, wherein if the detachable communication device is not capable of using the wireless power supply, the CPU causes a display device to display information for notifying that the detachable communication device that is currently connected is removed from the electronic device.

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

5. The electronic device according to claim 1, wherein a communication protocol of the first communicator conforms to Near Field Communication (NFC) standard.

6. The electronic device according to claim 1, wherein if the detachable communication device and the connection interface are connected, the CPU obtains data relating to the detachable communication device that is currently connected from the detachable communication device, and

wherein the CPU determines whether the detachable communication device that is currently connected is capable of using the wireless power supply by using the data relating to the detachable communication device that is currently connected.

7. The electronic device according to claim 1, wherein the detachable communication device performs a predetermined authentication using the second communicator.

8. The electronic device according to claim 1, wherein the detachable communication device performs an electronic payment using the second communicator.

9. The electronic device according to claim 1, wherein the detachable communication device acts as at least one of a memory card and a SIM (subscriber identity module) card.

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

a power supplier that wirelessly supplies power;

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

a CPU that performs a process of limiting the wireless power supply to the electronic device if the communicator receives data for notifying the power supply apparatus that the detachable communication device that is currently connected is not capable of using the wireless power supply.

11. A method of controlling an electronic device comprising:

determining whether a detachable communication device is capable of using a wireless power supply if the detachable communication device is connected with a interface to the electronic device, wherein the electronic device includes a power receiver that wirelessly receives power from a power supply apparatus, a first communicator that performs wireless communication, and the connection interface that connects the detachable communication device to the electronic device, the detachable communication device including a second communicator that performs wireless communication; and

controlling the first communicator to transmit data for notifying the power supply apparatus that the detachable communication device that is currently connected is not capable of using the wireless power supply if the detachable communication device that is currently connected is not capable of using the wireless power supply.

12. 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 detachable communication device is capable of using a wireless power supply of the power supply apparatus if the detachable communication device is connected with a connection interface to the electronic device, wherein the electronic device includes a power receiver that wirelessly receives power from a power supply apparatus, a first communicator that performs wireless communication, and the connection interface that connects the detachable communication device to the electronic device, the detachable communication device including a second communicator that performs wireless communication; and

controlling the first communicator to transmit data for notifying the power supply apparatus that the detachable communication device that is currently connected is not capable of using the wireless power supply if the detachable communication device that is currently connected is not capable of using the wireless power supply.
