Abstract

A power supply apparatus that wirelessly supplies power includes a detection unit configured to detect a power receiving apparatus, a receiving unit configured to receive, from the power receiving apparatus detected by the detection unit, identification information identifying the power receiving apparatus, a power-supply control unit configured to compare the identification information received by the receiving unit with identification information stored in a storage unit and identifying an allowed device for which power supply is allowed, thereby allowing power supply to the power receiving apparatus when both identification information match each other, and a power supply unit configured to perform the power supply to the power receiving apparatus for which the power supply is allowed by the power-supply control unit.

Claims

1. A power supply apparatus having a wireless power supply function of wirelessly supplying power to an external apparatus based on a first standard and a wireless communication function of performing wireless communication based on a second standard different from the first standard, the power supply apparatus comprising:

a first receiving unit configured to receive, from an external apparatus, an authentication key corresponding to the wireless communication function;

an authentication unit configured to perform, based on the authentication key, authentication processing corresponding to the wireless communication function;

a registration unit configured to register identification information of the external apparatus in a management table in a case where the authentication processing has ended successfully;

a second receiving unit configured to receive, from the external apparatus, identification information of the external apparatus via communication corresponding to the wireless power supply function;

a determining unit configured to determine whether or not the identification information received by the second receiving unit has been registered in the management table; and

a power supply unit configured to wirelessly supply power to the external apparatus in a case where the determining unit has determined that the identification information received by the second receiving unit has been registered in the management table, for which the power supply is allowed by the power-supply control unit,

wherein, in a case where the determining unit has determined that the identification information received by the second receiving unit has not been registered in the management table, the power supply unit does not supply power to the external apparatus.

2. The power supply apparatus according to claim 1, wherein history information of a service executed by the power supply apparatus is further registered in the management table, and

wherein, in a case where the determining unit has determined that the identification information received by the second receiving unit has been registered in the management table and history information corresponding to the external apparatus has been registered in the management table, the power-supply unit wireless supplies power to the external apparatus.

3. The power supply apparatus according to claim 1, further comprising:

a display unit configured to display error information in a case where the determining unit has determined that the identification information received by the second receiving unit has not been registered in the management table.

4. The power supply apparatus according to claim 1, wherein the power supply apparatus is a printing apparatus configured to perform printing.

5. The power supply apparatus according to claim 2, wherein the service includes at least a direct print service.

6. A power supply method having a wireless power supply function of wirelessly supplying power to an external apparatus based on a first standard and a wireless communication function of performing wireless communication based on a second standard different from the first standard, the power supply method comprising:

receiving, from an external apparatus, an authentication key corresponding to the wireless communication function;

performing, based on the authentication key, authentication processing corresponding to the wireless communication function;

registering identification information of the external apparatus in a management table in a case where the authentication processing has ended successfully;

receiving, from the external apparatus, identification information of the external apparatus via communication corresponding to the wireless power supply function;

determining whether or not the identification information received has been registered in the management table; and

wirelessly supplying power to the external apparatus in a case where the determined identification information received has been registered in the management table,

wherein, in a case where the determined identification information received has not been registered in the management table, not wirelessly supplying power to the external apparatus.

7. A non-transitory computer-readable storage medium that stores computer executable instructions that cause a computer to execute a method to wirelessly supply power to an external apparatus based on a first standard and a wireless communication function of performing wireless communication based on a second standard different from the first standard, the method comprising:

receiving, from an external apparatus, an authentication key corresponding to the wireless communication function;

performing, based on the authentication key, authentication processing corresponding to the wireless communication function;

registering identification information of the external apparatus in a management table in a case where the authentication processing has ended successfully;

receiving, from the external apparatus, identification information of the external apparatus via communication corresponding to the wireless power supply function;

determining whether or not the identification information received has been registered in the management table; and

wirelessly supplying power to the external apparatus in a case where the determined identification information received has been registered in the management table,

wherein, in a case where the determined identification information received has not been registered in the management table, not wirelessly supplying power to the external apparatus.
