Abstract

In a wireless power supply system, a power transmitting apparatus wirelessly supplies power to an assigned power receiving apparatus. The wireless power supply system includes an assigning unit that assigns the power receiving apparatus to the power transmitting apparatus, and a determining unit that, when the assigning unit assigns a particular power receiving apparatus to a plurality of power transmitting apparatuses, determines a power supply schedule such that the plurality of power transmitting apparatuses supply the power to the particular power receiving apparatus, not simultaneously.

Claims

1. A wireless power supply system for wirelessly supplying power to a power receiving apparatus assigned comprising:

an assigning unit configured to assign the power receiving apparatus to a power transmitting apparatus; and

a determining unit configured to determine a power supplying schedule such that, when the assigning unit assigns a particular power receiving apparatus to a plurality of power transmitting apparatuses, the plurality of power transmitting apparatuses supply the power to the particular power receiving apparatus, not simultaneously.

2. The wireless power supply system according to claim 1, further comprising

a notifying unit configured to notify the power supplying schedule determined by the determining unit to the plurality of power transmitting apparatuses.

3. The wireless power supply system according to claim 1, wherein

the power transmitting apparatuses supply the power to a plurality of the power receiving apparatuses assigned by the assigning unit, successively, by switching the power receiving apparatus to be supplied with the power, and

the determining unit determines a timing of the switching of the power supplying to the power receiving apparatus from the plurality of power transmitting apparatuses, so as to supply the particular power receiving apparatus, not simultaneously from the plurality of the power transmitting apparatus.

4. An assigning apparatus for assigning a power receiving apparatus to a power transmitting apparatus capable of wirelessly supplying power comprising:

an assigning unit configured to assign the power receiving apparatus to a power transmitting apparatus; and

a determining unit configured to determine a power supplying schedule such that, when the assigning unit assigns a particular power receiving apparatus to a plurality of power transmitting apparatuses, the plurality of power transmitting apparatuses supply the power to the particular power receiving apparatus, not simultaneously.

5. The assigning apparatus according to claim 4, further comprising

a notifying unit configured to notify the power supplying schedule determined by the determining unit to the plurality of power transmitting apparatuses.

6. The assigning apparatus according to claim 4, wherein

the power transmitting apparatuses supply the power to a plurality of the power receiving apparatuses assigned by the assigning unit, successively, by switching the power receiving apparatus to be supplied with the power, and

the determining unit determines a timing of the switching of the power supplying to the power receiving apparatus from the plurality of power transmitting apparatuses, so as to supply the particular power receiving apparatus, not simultaneously from the plurality of the power transmitting apparatus.
