Abstract

A power supplying apparatus includes a power supplying unit that contactlessly supplies power to a power receiving apparatus, a communication unit that wirelessly communicates with the power receiving apparatus, and a control unit that controls supply of power and communication such that the supply of power and the communication are exclusively executed, wherein when communication is executed after supply of power is executed, communication is disabled until power output from the power supplying unit becomes less than or equal to a predetermined value.

Claims

1. A power supplying apparatus comprising:

a power supplying unit configured to contactlessly supply power to a power receiving apparatus;

a communication unit configured to wirelessly communicate with the power receiving apparatus; and

a control unit configured to control the supply of power by the power supplying unit and the communication by the communication unit such that the supply of power and the communication are exclusively executed,

wherein, in a case where the control unit performs control such that the communication is executed after the supply of power is executed, the control unit determines whether or not output power from the power supplying unit is less than or equal to a predetermined value;

wherein, in a case where it is determined by the control unit that the output power from the power supplying unit is not less than or equal to the predetermined value, the control unit disables the communication unit, and

wherein, in a case where it is determined by the control unit that the output power from the power supplying unit is less than or equal to the predetermined value, the control unit enables the communication unit.

2. The power supplying apparatus according to claim 1, wherein in a case where the control unit performs control such that the supply of power is executed after the communication is executed, the control unit executes the supply of power after disabling the communication unit.

3. The power supplying apparatus according to claim 1, wherein the control unit stops output of the power supplying unit while the communication with the power receiving apparatus is performed by the communication unit.

4. The power supplying apparatus according to claim 1, wherein at a time of switching from the supply of power to the communication, the control unit controls the output power of the power supplying unit to a predetermined value or less before enabling the communication unit.

5. The power supplying apparatus according to claim 1, further comprising a first antenna and a second antenna,

wherein the power supplying unit contactlessly supplies power to the power receiving apparatus using the first antenna, and

wherein the communication unit wirelessly communicates with the power receiving apparatus using the second antenna.

6. The power supplying apparatus according to claim 5, wherein the second antenna is located in a position within a power supply range of the first antenna.

7. The power supplying apparatus according to claim 1, wherein in a case where the control unit performs control such that the supply of power is executed after the communication is executed, the control unit does not start the supply of power until output from the communication unit becomes less than or equal to a second value.

8. The power supplying apparatus according to claim 7, wherein the second value is less than the predetermined value.

9. The power supplying apparatus according to claim 1, wherein the control unit performs control such that the supply of power and the wireless communication are repeatedly executed exclusively and alternately.

10. A method of controlling a power supplying apparatus including a power supplying unit configured to contactlessly supply power to a power receiving apparatus and a communication unit configured to wirelessly communicate with the power receiving apparatus, the method comprising:

controlling the supply of power by the power supplying unit and the communication by the communication unit such that the supply of power and the communication are exclusively executed,

wherein, in a case where the controlling performs control such that the communication is executed after the supply of power is executed, the controlling determines whether or not output power from the power supplying unit is less than or equal to a predetermined value;

wherein, in a case where it is determined that the output power from the power supplying unit is not less than or equal to the predetermined value, the controlling disables the communication unit, di, and

wherein, in a case where it is determined that the output power from the power supplying unit is less than or equal to a predetermined value, the controlling enables the communication unit.

12. The method according to claim 10, wherein in a case where the controlling performs control such that the supply of power is executed after the communication is executed, the controlling executes the supply of power after disabling the communication unit.

13. The method according to claim 10, wherein the controlling stops output of the power supplying unit while the communication with the power receiving apparatus is performed by the communication unit.

14. The method according to claim 10, wherein at a time of switching from the supply of power to the communication, the controlling controls the output power of the power supplying unit to a predetermined value or less before enabling the communication unit.

15. The method according to claim 10,

wherein the power supply apparatus comprises a first antenna and a second antenna,

wherein the power supplying unit contactlessly supplies power to the power receiving apparatus using the first antenna, and

wherein the communication unit wirelessly communicates with the power receiving apparatus using the second antenna.

11. A non-transitory storage medium storing computer executable instructions that cause a power supplying apparatus including a power supplying unit configured to contactlessly supply power to a power receiving apparatus and a communication unit configured to wirelessly communicate with the power receiving apparatus to execute a method, the method comprising:

controlling the supply of power by the power supplying unit and the communication by the communication unit such that the supply of power and the communication are exclusively executed,

wherein, in a case where the controlling performs control such that the communication is executed after the supply of power is executed, the controlling determines whether or not output power from the power supplying unit is less than or equal to a predetermined value,

wherein, in a case where it is determined that the output power from the power supplying unit is not less than or equal to the predetermined value, the controlling disables the communication unit, and

wherein, in a case where it is determined that the output power from the power supplying unit is less than or equal to a predetermined value, the controlling enables the communication unit.

16. The non-transitory storage medium according to claim 11, wherein in a case where the controlling performs control such that the supply of power is executed after the communication is executed, the controlling executes the supply of power after disabling the communication unit.

17. The non-transitory storage medium according to claim 11, wherein the controlling stops output of the power supplying unit while the communication with the power receiving apparatus is performed by the communication unit.

18. The non-transitory storage medium according to claim 11, wherein at a time of switching from the supply of power to the communication, the controlling controls the output power of the power supplying unit to a predetermined value or less before enabling the communication unit.

19. The non-transitory storage medium according to claim 11,

wherein the power supply apparatus comprises a first antenna and a second antenna,

wherein the power supplying unit contactlessly supplies power to the power receiving apparatus using the first antenna, and

wherein the communication unit wirelessly communicates with the power receiving apparatus using the second antenna.
