Abstract

A power supply apparatus includes a first power supply unit used for a first power supply method, a second power supply unit used for a second power supply method different from the first power supply method, a first communication unit used for a first control method for controlling power supplying, a second communication unit used for a second control method different from the first control method, and a control unit that sets the power supply apparatus in any one of a first, second, and third mode based on authentication with an electronic apparatus. The control unit operates so that the power supply apparatus performs power supply to the electronic apparatus based on a set mode.

Claims

1. A power supply apparatus comprising:

a first power supply unit configured to be used for a first power supply method;

a second power supply unit configured to be used for a second power supply method different from the first power supply method;

a first communication unit configured to be used for a first control method for controlling power supplying;

a second communication unit configured to be used for a second control method different from the first control method; and

a control unit configured to set the power supply apparatus in any one of a first mode, a second mode, and a third mode based on authentication with an electronic apparatus;

wherein the control unit operates so that the power supply apparatus performs power supply to the electronic apparatus based on a set mode, wherein the first mode is a mode for performing power supplying based on the first power supply method and for controlling power supplying based on the first control method, wherein the second mode is a mode for performing power supplying based on the second power supply method and for controlling power supplying based on the first control method, and wherein the third mode is a mode for performing power supplying based on the second power supply method and for controlling power supplying based on the second control method.

2. The power supply apparatus according to claim 1, wherein the first power supply method is a method for supplying power based on a first frequency, and the second power supply method is a method for supplying power based on a second frequency different from the first frequency.

3. The power supply apparatus according to claim 2, wherein the first frequency is a frequency higher than the second frequency.

4. The power supply apparatus according to claim 2, wherein the first frequency is a frequency defined by a Near Field Communication (NFC) standard.

5. The power supply apparatus according to claim 2, wherein the second frequency is a frequency defined by a Qi standard.

6. The power supply apparatus according to claim 1, wherein the first power supply method is a method for supplying power by using magnetic resonance.

7. The power supply apparatus according to claim 1, wherein the second power supply method is a method for supplying power by using electromagnetic induction.

8. The power supply apparatus according to claim 1, wherein the first control method is a method for performing communication for controlling power supplying based on a first frequency, and the second power supply method is a method for performing communication for controlling power supplying based on a second frequency different from the first frequency.

9. The power supply apparatus according to claim 8, wherein the first frequency is a frequency higher than the second frequency.

10. The power supply apparatus according to claim 8, wherein the first frequency is a frequency defined by a Near Field Communication (NFC) standard.

11. The power supply apparatus according to claim 8, wherein the second frequency is a frequency defined by a Qi standard.

12. The power supply apparatus according to claim 1, wherein, before transmitting power, the first communication unit superimposes data for controlling power supplying on the power.

13. The power supply apparatus according to claim 1, wherein the first communication unit transmits data for controlling power supplying based on ASK modulation.

14. The power supply apparatus according to claim 1, wherein the first communication unit operates as a reader/writer.

15. The power supply apparatus according to claim 1, wherein the first communication unit operates as a peer-to-peer target.

16. The power supply apparatus according to claim 1, wherein the control unit performs authentication with the electronic apparatus by using the first communication unit.

17. The power supply apparatus according to claim 1, wherein, if the control unit cannot perform authentication with the electronic apparatus, the control unit sets the power supply apparatus in the third mode.

18. A control method for controlling the power supply apparatus according to claim 1.

19. A non-transitory computer readable storage medium for storing a computer program for realizing a power supply apparatus, the power supply apparatus comprising:

a first power supply unit configured to be used for a first power supply method;

a second power supply unit configured to be used for a second power supply method different from the first power supply method;

a first communication unit configured to be used for a first control method for controlling power supplying;

a second communication unit configured to be used for a second control method different from the first control method; and

a control unit configured to set the power supply apparatus in any one of a first mode, a second mode, and a third mode based on authentication with an electronic apparatus;
