Abstract

There is provided a power feeding apparatus including a remaining battery level reception unit configured to receive a remaining battery level of a respective secondary battery included in a respective power receiving apparatus among a plurality of power receiving apparatuses from the respective power receiving apparatuses, a power feeding time determination unit configured to determine power feeding time for the power receiving apparatuses based on the remaining battery level, and a power feeding unit configured to wirelessly feed power to the power receiving apparatuses for the power feeding time.

Claims

1. A power feeding apparatus comprising:

a remaining battery level reception unit configured to receive a remaining battery level of a respective secondary battery included in a respective power receiving apparatus among a plurality of power receiving apparatuses from the respective power receiving apparatuses;

a power feeding time determination unit configured to determine power feeding time for the power receiving apparatuses based on the remaining battery level; and

a power feeding unit configured to wirelessly feed power to the power receiving apparatuses for the power feeding time.

2. The power feeding apparatus according to claim 1, wherein the remaining battery level is information indicating a ratio of the remaining battery level to electrical energy of the secondary battery at a full charge, and

wherein the power feeding time determination unit is configured to determine the power feeding time based on the ratio.

3. The power feeding apparatus according to claim 2, wherein the power feeding time determination unit is configured to determine the power feeding time so that as the ratio is higher, the power feeding time is shorter.

4. A power feeding apparatus comprising:

an operating state reception unit configured to receive an operating state from each of a plurality of power receiving apparatuses;

an apparatus selection unit configured to select a power receiving apparatus to be fed power based on the operating state; and

a power feeding unit configured to wirelessly feed power to the power receiving apparatus selected by the apparatus selection unit.

5. A power feeding apparatus configured to feed power to a plurality of power receiving apparatuses, the power feeding apparatus comprising:

a first power feeding unit configured to feed power to a power receiving apparatus arranged inside the power feeding apparatus from among the plurality of power receiving apparatuses;

a second power feeding unit configured to wirelessly feed power to a power receiving apparatus arranged outside the power feeding apparatus from among the plurality of power receiving apparatuses; and

a power feeding control unit configured to control the feeding of the power by the second power feeding unit based on an amount of power fed by the first power feeding unit.

6. A power feeding method to be performed by a power feeding apparatus, the power feeding method comprising:

receiving a remaining battery level of a respective secondary battery included in a respective power receiving apparatus among a plurality of power receiving apparatuses from the respective power receiving apparatuses;

determining power feeding time for the power receiving apparatuses based on the remaining battery level; and

wirelessly feeding power to the power receiving apparatuses for the power feeding time.

7. A power feeding method to be performed by a power feeding apparatus, the power feeding method comprising:

receiving an operating state from each of a plurality of power receiving apparatuses;

selecting a power receiving apparatus to be fed power based on the operating state; and

wirelessly feeding power to the selected power receiving apparatus.

8. A power feeding method to be performed by a power feeding apparatus configured to feed power to a plurality of power receiving apparatuses, the power feeding method comprising:

performing second power feeding wirelessly to a power receiving apparatus arranged outside the power feeding apparatus from among the plurality of power receiving apparatuses; and

controlling the feeding of the power in the second power feeding based on an amount of power fed in the first power feeding.

9. A non-transitory computer-readable storage medium storing a program for causing a computer to function as:

a power feeding time determination unit configured to determine power feeding time for the power receiving apparatuses based on the respective remaining battery level; and

a power feeding control unit configured to perform control so that power is wirelessly fed to the respective power receiving apparatuses for the power feeding time.

10. A non-transitory computer-readable storage medium storing a program for causing a computer to function as:

an operating state reception unit configured to receive an operating state from each of a plurality of power receiving apparatuses;

an apparatus selection unit configured to select a power receiving apparatus to be fed power based on the operating state; and

a power feeding control unit configured to perform control so that power is wirelessly fed to the power receiving apparatus selected by the apparatus selection unit.

11. A non-transitory computer-readable storage medium storing a program for causing a computer to function as a power feeding control unit configured to control feeding of power by a second power feeding unit based on an amount of power fed by a first power feeding unit, the first power feeding unit being configured to feed power to a power receiving apparatus arranged inside a power feeding apparatus from among a plurality of power receiving apparatuses, the second power feeding unit being configured to wirelessly feed power to a power receiving apparatus arranged outside the power feeding apparatus among the plurality of power receiving apparatuses.
