Abstract

A power supply apparatus includes a power supply unit configured to wirelessly supply power to an electronic apparatus, a communication unit configured to communicate with the electronic apparatus, a detection unit configured to detect a state related to a wireless power supply to the electronic apparatus, and a control unit configured to, when a change in the state related to the wireless power supply to the electronic apparatus is detected while power is being supplied to the electronic apparatus by the power supply unit, start process for causing the communication unit to acquire data related to the electronic apparatus from the electronic apparatus.

Claims

1. A power supply apparatus comprising:

a power supply unit configured to wirelessly supply power to an electronic apparatus;

a communication unit configured to communicate with the electronic apparatus;

a detection unit configured to detect a state related to a wireless power supply to the electronic apparatus; and

a control unit configured to start a process for causing the communication unit to acquire data related to the electronic apparatus from the electronic apparatus when a change in the state related to the wireless power supply to the electronic apparatus is detected while power is being supplied to the electronic apparatus by the power supply unit.

2. The power supply apparatus according to claim 1, wherein, based on the data acquired from the electronic apparatus, the control unit controls the power supply to the electronic apparatus.

3. The power supply apparatus according to claim 1, wherein, when a change in the state related to the wireless power supply to the electronic apparatus is detected while the power is being supplied to the electronic apparatus by the power supply unit, the control unit performs a process for limiting power supply to the electronic apparatus.

4. The power supply apparatus according to claim 1, wherein, based on the data acquired from the electronic apparatus, the control unit performs a process for detecting an error related to the electronic apparatus.

5. The power supply apparatus according to claim 1, wherein, when an error related to the electronic apparatus is detected based on the data acquired from the electronic apparatus, the control unit performs a process for notifying the error related to the electronic apparatus.

6. The power supply apparatus according to claim 1, wherein, when an error related to the electronic apparatus is detected based on the data acquired from the electronic apparatus, the control unit performs a process for notifying a warning.

7. The power supply apparatus according to claim 1, wherein the control unit controls power supply to the electronic apparatus according to a type of the error related to the electronic apparatus detected based on the data acquired from the electronic apparatus.

8. The power supply apparatus according to claim 1, wherein the detection unit detects the state related to the wireless power supply to the electronic apparatus according to a reflection of the power output from the power supply unit.

9. The power supply apparatus according to claim 1, wherein the detection unit detects the state related to the wireless power supply to the electronic apparatus according to a current flowing in the power supply unit.

10. The power supply apparatus according to claim 1, further comprising a temperature detection unit configured to detect a temperature,

wherein the detection unit detects the state related to the wireless power supply to the electronic apparatus based on the temperature detected by the temperature detection unit.

11. A method comprising:

wirelessly supplying power to an electronic apparatus;

communicating with the electronic apparatus;

detecting a state related to the wireless power supply to the electronic apparatus; and

starting a process for acquiring data related to the electronic apparatus from the electronic apparatus when a change in the state related to the wireless power supply to the electronic apparatus is detected while the power is being supplied to the electronic apparatus.

12. A recording medium storing a program for causing a computer to execute a method, the method comprising:

wirelessly supplying power to an electronic apparatus;

communicating with the electronic apparatus;

detecting a state related to the wireless power supply to the electronic apparatus; and

starting a process for acquiring data related to the electronic apparatus from the electronic apparatus when a change in the state related to the wireless power supply to the electronic apparatus is detected while the power is being supplied to the electronic apparatus.
