Abstract

A power supply apparatus includes a power supply unit configured to perform power supply, a communication unit configured to perform communication, and a control unit configured to control, based on data received by the communication unit, a power supply for an electronic device.

Claims

1. A power supply apparatus comprising:

a power supply unit configured to perform wireless power supply based on a first frequency;

a communication unit configured to perform communication based on a second frequency; and

a control unit configured to control the communication unit to transmit, before predetermined power is supplied to an electronic device, a first command for acquiring at least one of data corresponding to a first address and data corresponding to a second address from the electronic device, to the electronic device,

wherein the control unit determines whether the electronic device is adaptable to the power supply unit by using the data corresponding to the first address,

wherein the control unit determines whether to perform a power supply process for supplying the predetermined power to the electronic device by using the data corresponding to the second address,

wherein, in a case where the electronic device is adaptable to the power supply unit, and when the power supply process is started, the control unit controls the communication unit to transmit a second command including data corresponding to a third address to the electronic device to notify the electronic device of starting to supply the predetermined power, and

wherein the data corresponding to the first address is unrewritable from the power supply apparatus and the electronic device, the data corresponding to the second address is rewritable from the electronic device and unrewritable from the power supply apparatus, and the data corresponding to the third address is unrewritable from the electronic device and rewritable from the power supply apparatus.

2. The power supply apparatus according to claim 1, wherein the predetermined power is set according to the data corresponding to the second address, and the data corresponding to the second address includes data regarding a battery connected to the electronic device.

3. The power supply apparatus according to claim 1, wherein the predetermined power is set according to the data corresponding to the second address, and the data corresponding to the second address includes data indicating a status of the electronic device.

4. The power supply apparatus according to claim 1, wherein the data corresponding to the first address includes data used for identifying the electronic device.

5. The power supply apparatus according to claim 1, wherein the data corresponding to the first address includes data regarding a power reception capability of the electronic device.

6. The power supply apparatus according to claim 1, wherein the data corresponding to the third address includes data indicating whether to start to supply the predetermined power.

7. The power supply apparatus according to claim 1, wherein the first command and the second command comply with a NFC Data Exchange Format (NDEF).

8. The power supply apparatus according to claim 1, wherein the second frequency is a frequency complying with a Near Field Communication (NFC) standard.

9. The power supply apparatus according to claim 1, wherein the second frequency is different from the first frequency.

10. A control method for controlling a power supply apparatus including a power supply unit configured to perform wireless power supply based on a first frequency and a communication unit configured to perform communication based on a second frequency, the method comprising:

controlling the communication unit to transmit, before predetermined power is supplied to an electronic device, a first command for acquiring at least one of data corresponding to a first address and data corresponding to a second address from the electronic device, to the electronic device;

determining whether the electronic device is adaptable to the power supply unit by using the data corresponding to the first address;

determining whether to perform a power supply process for supplying the predetermined power to the electronic device by using the data corresponding to the second address; and

controlling the communication unit to transmit, when the electronic device is adaptable to the power supply unit, in a case of starting the power supply process, a second command including data corresponding to a third address to the electronic device to notify the electronic device of starting to supply the predetermined power,

wherein the data corresponding to the first address is unrewritable from the power supply apparatus and the electronic device, the data corresponding to the second address is rewritable from the electronic device and unrewritable from the power supply apparatus, and the data corresponding to the third address is unrewritable from the electronic device and rewritable from the power supply apparatus.

11. An electronic device comprising:

a power reception unit configured to receive power based on a first frequency;

a communication unit configured to perform communication based on a second frequency;

a storage unit configured to store a predetermined table including data corresponding to a first address, data corresponding to a second address, and data corresponding to a third address;

a reading unit configured to read, when a first command for acquiring at least one of the data corresponding to the first address and the data corresponding to the second address from the electronic device is received from a power supply apparatus, the data from the predetermined table according to the first command;

a writing unit configured to write, in a case where a second command including the data corresponding to the third address is received from the power supply apparatus, the data included in the second command in the predetermined table; and

a control unit configured to control, in a case where the second command including the data corresponding to the third address is received from the power supply apparatus, charging of a battery after data indicating starting to supply predetermined power by the power supply apparatus has been written in the predetermined table,

wherein the data corresponding to the first address is unrewritable from the power supply apparatus and the electronic device, the data corresponding to the second address is rewritable from the electronic device and unrewritable from the power supply apparatus, and the data corresponding to the third address is unrewritable from the electronic device and rewritable from the power supply apparatus.

12. The electronic device according to claim 11, wherein the predetermined power is set according to the data corresponding to the second address, and the data corresponding to the second address includes data regarding the battery.

13. The electronic device according to claim 11, wherein the predetermined power is set according to the data corresponding to the second address, and the data corresponding to the second address includes data indicating a status of the electronic device.

14. The electronic device according to claim 11, wherein the data corresponding to the first address includes data used for identifying the electronic device.

15. The electronic device according to claim 11, wherein the data corresponding to the first address includes data regarding a power reception capability of the electronic device.

16. The electronic device according to claim 11, wherein the data corresponding to the third address includes data indicating whether to start supplying the predetermined power.

17. The electronic device according to claim 11, wherein the first command and the second command comply with a NFC Data Exchange Format (NDEF).
