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 power feeding unit configured to wirelessly feed power to a power receiving apparatus;

a reception unit configured to receive, from a first power receiving apparatus, remaining battery level information of a secondary battery of the first power receiving apparatus;

a determination unit configured to determine power feeding time for feeding of power to the first power receiving apparatus, based on the remaining battery level information;

a first switching unit configured to switch a power feeding destination from the first power receiving apparatus to a second power receiving apparatus according to a lapse of the power feeding time from start of power feeding to the first power receiving apparatus; and

a second switching unit configured to switch the power feeding destination from the first power receiving apparatus to the second power receiving apparatus in response to the power feeding apparatus receiving a stop request of power feeding from the first power receiving apparatus even before the lapse of the power feeding time.

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

5. The power feeding apparatus according to claim 1, wherein the power feeding apparatus is a printing apparatus that has a print function.

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

wirelessly feeding power to a power receiving apparatus;

receiving, from a first power receiving apparatus, remaining battery level information of a secondary battery of the first power receiving apparatus;

determining power feeding time for feeding of power to the first power receiving apparatus, based on the remaining battery level information;

switching a power feeding destination from the first power receiving apparatus to a second power receiving apparatus according to a lapse of the power feeding time from start of power feeding to the first power receiving apparatus; and

switching the power feeding destination from the first power receiving apparatus to the second power receiving apparatus in response to the power feeding apparatus receiving a stop request of power feeding from the first power receiving apparatus even before the lapse of the power feeding time.

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

a power feeding unit configured to wirelessly feed power to a power receiving apparatus;

a reception unit configured to receive, from a first power receiving apparatus, remaining battery level information of a secondary battery of the first power receiving apparatus;

a determination unit configured to determine power feeding time for feeding of power to the first power receiving apparatus, based on the remaining battery level information;

a first switching unit configured to switch a power feeding destination from the first power receiving apparatus to a second power receiving apparatus according to a lapse of the power feeding time from start of power feeding to the first power receiving apparatus; and

a second switching unit configured to switch the power feeding destination from the first power receiving apparatus to the second power receiving apparatus in response to the power feeding apparatus receiving a stop request of power feeding from the first power receiving apparatus even before the lapse of the power feeding time.
