Abstract

A power transmission apparatus includes a wireless power transmission unit that wirelessly transmits power to an electronic device, a communication unit that performs data communication with the electronic device, an acquisition unit that acquires status information of the electronic device from the electronic device, and a control unit that controls, based on the acquired status information, whether data communication using the communication unit or power supply using the wireless power transmission unit is performed.

Claims

1. A power transmission apparatus comprising:

a wireless power transmission unit that wirelessly transmits power to an electronic device;

a communication unit that performs data communication with the electronic device;

an acquisition unit that acquires status information of the electronic device from the electronic device; and

a control unit that controls, based on the acquired status information, whether data communication using the communication unit or power supply using the wireless power transmission unit is performed.

2. The power transmission apparatus according to claim 1, wherein the control unit determines whether the electronic device includes updated data, based on the acquired status information.

3. The power transmission apparatus according to claim 1, wherein the control unit determines a remaining amount of a battery, based on the acquired status information.

4. The power transmission apparatus according to claim 1, wherein the control unit controls data communication using the communication unit, when the electronic device includes updated data and a remaining amount of a battery is greater than a predetermined value.

5. The power transmission apparatus according to claim 1, wherein the control unit controls power supply using the wireless power transmission unit, when the electronic device includes no updated data.

6. The power transmission apparatus according to claim 1, wherein the control unit controls power supply using the wireless power transmission unit, when a remaining amount of a battery is less or equal to than a predetermined value.

7. A method comprising:

causing a wireless power transmission unit to wirelessly transmit power to an electronic device;

causing a communication unit to perform data communication with the electronic device;

acquiring status information of the electronic device from the electronic device; and

controlling, based on the acquired status information, whether data communication using the communication unit or power supply using the wireless power transmission unit is performed.

8. The method according to claim 7, further comprising determining, based on the acquired status information, whether the electronic device includes updated data.

9. The method according to claim 7, further comprising determining, based on the acquired status information, a remaining amount of a battery.

10. The method according to claim 7, further comprising controlling data communication using the communication unit, when the electronic device includes updated data and a remaining amount of a battery is greater than a predetermined value.

11. The method according to claim 7, further comprising controlling power supply using the wireless power transmission unit, when the electronic device includes no updated data.

12. The method according to claim 7, further comprising controlling power supply using the wireless power transmission unit, when a remaining amount of a battery is less or equal to a predetermined value.

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

causing a wireless power transmission unit to wirelessly transmit power to an electronic device;

causing a communication unit to perform data communication with the electronic device;

acquiring status information of the electronic device from the electronic device; and

controlling, based on the acquired status information, whether data communication using the communication unit or power supply using the wireless power transmission unit is performed.
