Abstract

A power supply apparatus includes a power supply unit that wirelessly supplies power to an electronic device, a communication unit that transmits information related to the power supply apparatus to the electronic device, transmits information for requesting the electronic device for transmitting information related to the electronic device, when a predetermined time has elapsed after the information related to the power supply apparatus is transmitted to the electronic device, and receives the information related to the electronic device from the electronic device; and a control unit that uses the information related to the electronic device to control power to be wirelessly supply to the electronic device, after the information related to the electronic device is received from the electronic device.

Claims

1. A power supply apparatus comprising:

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

a communication unit that transmits information related to the power supply apparatus to the electronic device, transmits information for requesting the electronic device for transmitting information related to the electronic device, when a predetermined time has elapsed after the information related to the power supply apparatus is transmitted to the electronic device, and receives the information related to the electronic device from the electronic device; and

a control unit that uses the information related to the electronic device to control power to be wirelessly supply to the electronic device, after the information related to the electronic device is received from the electronic device.

2. The power supply apparatus according to claim 1, wherein information indicating the predetermined time is received from the electronic device by the communication unit.

3. The power supply apparatus according to claim 1, wherein information indicating the predetermined time is received from the electronic device by the communication unit before the information related to the power supply apparatus is transmitted to the electronic device.

4. The power supply apparatus according to claim 1, wherein the information for requesting the electronic device for transmitting information related to the electronic device is transmitted to the electronic device, when the predetermined time is elapsed after the information related to the power supply apparatus is transmitted to the electronic device.

5. The power supply apparatus according to claim 1, wherein the information related to the power supply apparatus includes information indicating whether or not an error has occurred in the power supply apparatus, information indicating a maximum value of power that the power supply apparatus is allowed to output, or information indicating a power supply method supported by the power supply apparatus.

6. The power supply apparatus according to claim 1, wherein the information related to the electronic device includes information indicating whether or not an error has occurred in the electronic device, information for requesting the power supply apparatus for increasing or decreasing power to be output from the power supply apparatus, information indicating a remaining capacity of a battery connected to the electronic device, or information related to charging of the battery.

7. The power supply apparatus according to claim 1, wherein the control unit controls whether to cause the power supply unit to output first power or to cause the power supply unit to output second power that is higher than the first power, based on whether or not the information related to the electronic device is updated by the electronic device.

8. The power supply apparatus according to claim 1, wherein the control unit causes the power supply unit to output second power that is higher than first power, after the information related to the electronic device is updated by the electronic device.

9. The power supply apparatus according to claim 8, wherein the control unit causes the power supply unit to output the first power, before the information related to the electronic device is updated by the electronic device.

10. A method comprising:

wirelessly supplying power from a power supply apparatus to an electronic device;

transmitting information related to the power supply apparatus to the electronic device;

transmitting information for requesting the electronic device for transmitting information related to the electronic device, when a predetermined time has elapsed after the information related to the power supply apparatus is transmitted to the electronic device;

receiving the information related to the electronic device from the electronic device; and

using the information related to the electronic device to control power to be wirelessly supply to the electronic device, after the information related to the electronic device is received from the electronic device.

11. A non-transitory storage medium that stores a program for causing a computer to execute a method, the method comprising:

wirelessly supplying power from a power supply apparatus to an electronic device;

transmitting information related to the power supply apparatus to the electronic device;

transmitting information for requesting the electronic device for transmitting information related to the electronic device, when a predetermined time has elapsed after the information related to the power supply apparatus is transmitted to the electronic device;

receiving the information related to the electronic device from the electronic device; and

using the information related to the electronic device to control power to be wirelessly supply to the electronic device, after the information related to the electronic device is received from the electronic device.
