Abstract

A power supply apparatus comprises a power supply unit which outputs power to a power receiving apparatus in a non-contact manner, a first communication unit which communicates with the power receiving apparatus through a first communication scheme, a second communication unit which communicates with the power receiving apparatus through a second communication scheme, and a control unit which carries out control such that first power is output from the power supply unit, and in the case where first device information and second device information obtained from the power receiving apparatus meet a predetermined condition, a state of connection with the power receiving apparatus is continued by the second communication unit.

Claims

a control unit configured to carry out control such that first power is output from the power supply unit, and in the case where first device information obtained from the power receiving apparatus by the first communication unit and second device information obtained from the power receiving apparatus by the second communication unit meet a predetermined condition, a state of connection with the power receiving apparatus is continued by the second communication unit.

2. The apparatus according to claim 1, wherein the control unit outputs second power to the power receiving apparatus using the power supply unit after a connection has been made with the power receiving apparatus using the second communication unit.

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

4. The apparatus according to claim 1, wherein a range in which the second communication unit can communicate is broader than a range in which the first communication unit can communicate.

5. The apparatus according to claim 1, wherein the first communication scheme is short-range wireless communication.

6. The apparatus according to claim 1, wherein

the control unit transmits a request signal requesting the first device information to the power receiving apparatus using the first communication unit, and outputs the first power from the power supply unit after a response signal responding to the request signal is received from the power receiving apparatus;

receives authentication information from the power receiving apparatus using the second communication unit; and

compares the second device information and the first device information included in the authentication information.

7. The apparatus according to claim 6, wherein the predetermined condition is a case where it is determined that the second device information included in the authentication information and the first device information in the response signal are the same.

8. The apparatus according to claim 6, wherein the control unit outputs the first power or third power using the power supply unit after the request signal has been transmitted to the power receiving apparatus using the first communication unit.

9. The apparatus according to claim 8, wherein the control unit outputs the first power using the power supply unit in the case where, after the request signal has been transmitted to the power receiving apparatus by the first communication unit, the response signal is received from the power receiving apparatus before a predetermined time elapses;

and

outputs the third power using the power supply unit in the case where the response signal has not been received from the power receiving apparatus before the predetermined time elapses.

10. The apparatus according to claim 8, wherein a time interval in which the request signal is transmitted by the first communication unit is shorter than a time interval in which the power supply unit outputs the third power.

11. The apparatus according to claim 8, wherein the second power is higher than the first power, and the first power is higher than the third power.

12. The apparatus according to claim 1, wherein the first communication scheme is a communication scheme corresponding to an NFC standard;

and

the second communication scheme is a communication scheme corresponding to a Bluetooth standard.

13. A power receiving apparatus which can receive power from a power supply apparatus in a non-contact manner, the power receiving apparatus comprising:

a power receiving unit configured to receive power from the power supply apparatus in a non-contact manner;

a first communication unit configured to communicate with the power supply apparatus through a first communication scheme;

a second communication unit configured to communicate with the power supply apparatus through a second communication scheme;

a storage unit configured to store device information; and

a control unit configured to transmit the device information to the power supply apparatus using the first communication unit in the case where a request for the device information has been received from the power supply apparatus, and transmit information for connecting to the power supply apparatus using the second communication unit in the case where predetermined power has been received from the power supply apparatus through the first communication unit.

14. The apparatus according to claim 13, wherein wherein after the first power has been received from the power supply apparatus, the control unit receives second power from the power supply apparatus in a state of connection to the power supply apparatus using the second communication unit;

and

the second power is higher than the first power.

15. The apparatus according to claim 13, wherein a range in which the second communication unit can communicate is broader than a range in which the first communication unit can communicate.

16. The apparatus according to claim 13, wherein the first communication scheme is short-range wireless communication.

17. The apparatus according to claim 13, wherein

the first communication scheme is a communication scheme corresponding to an NFC standard;

and

the second communication scheme is a communication scheme corresponding to a Bluetooth standard.
