Abstract

A power supply apparatus includes a power supply unit that wirelessly supply power to an electronic device, a first communication unit that communicates, based on a first communication method, with the electronic device, a second communication unit that communicates, based on a second communication method that is different from the first communication method, with the electronic device, and a control unit that controls the first communication unit so as to acquire authentication data for a communication between the second communication unit and the electronic device if a remaining capacity of a battery, connected to the electronic device, is equal to or more than a predetermined value.

Claims

1. A power supply apparatus comprising:

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

a first communication unit that communicates, based on a first communication method, with the electronic device to wirelessly supply power to the electronic device;

a second communication unit that communicates, based on a second communication method that is different from the first communication method, with the electronic device; and

a control unit that controls the first communication unit so as to acquire authentication data for a communication between the second communication unit and the electronic device if a remaining capacity of a battery, connected to the electronic device, is greater than or equal to a predetermined value.

2. The power supply apparatus according to claim 1, wherein the control unit controls the first communication unit not to acquire the authentication data from the electronic device until the remaining capacity of the battery exceeds the predetermined value if the remaining capacity of the battery is less than the predetermined value.

3. The power supply apparatus according to claim 1, wherein the control unit controls the second communication unit not to communicate with the electronic device until the remaining capacity of the battery exceeds the predetermined value, and controls the power supply unit so as to supply a predetermined power to be used for charging the battery to the electronic device until the remaining capacity of the battery exceeds the predetermined value.

4. The power supply apparatus according to claim 1, wherein the control unit controls the first communication unit so as to acquire the authentication data even if the remaining capacity of the battery is less than the predetermined value while the electronic device and an external power source apparatus are being connected.

5. The power supply apparatus according to claim 1, wherein the control unit controls the first communication unit so as to acquire the authentication data even if the remaining capacity of the battery is less than or equal to the predetermined value while the electronic device and a commercial power source are being connected.

6. The power supply apparatus according to claim 1, wherein the control unit controls the first communication unit so as to acquire the authentication data if the electronic device does not support a wireless power supply of the power supply apparatus.

7. The power supply apparatus according to claim 1, wherein the authentication data includes at least one of information indicating an address of the electronic device, information indicating a service set identifier (SSID) of the electronic device, information indicating an extended service set identifier (ESSID) of the electronic device, and information relating to encryption.

8. The power supply apparatus according to claim 1, wherein the control unit controls the second communication unit so as to receive data that the power supply apparatus does not acquire from the electronic device after the first communication unit acquires the authentication data from the electronic device.

9. The power supply apparatus according to claim 1, wherein the control unit controls the second communication unit so as to transmit data that the electronic device does not acquire from the power supply apparatus after the first communication unit acquires the authentication data from the electronic device.

10. The power supply apparatus according to claim 1, wherein the first communication method is a communication method based on a near field communication (NFC) standard.

11. The power supply apparatus according to claim 1, wherein the second communication method is a communication method based on either a wireless local area network standard or a Bluetooth standard.

12. A control method comprising:

communicating, based on a first communication method, with an electronic device to wirelessly supply power to the electronic device;

wirelessly supplying power to the electronic device; and

communicating, based on the first communication method, with the electronic device so as to acquire authentication data for communicating, based on a second communication method that is different from the first communication method, with the electronic device if a remaining capacity of a battery, connected to the electronic device, is greater than or equal to a predetermined value.

13. A recording medium recording a program for causing a computer to execute a method, the method comprising:

communicating, based on a first communication method, with an electronic device to wirelessly supply power to the electronic device;

wirelessly supplying power to the electronic device; and

communicating, based on the first communication method, with the electronic device to acquire authentication data for communicating, based on a second communication method that is different from the first communication method, with the electronic device if a remaining capacity of a battery, connected to the electronic device, is greater than or equal to a predetermined value.
