1. A power supply apparatus for supplying electric power to a plurality of power receiving apparatuses in a non-contact manner, the power supply apparatus comprising:
- a detection unit configured to detect that at least one of a first power receiving apparatus and a second power receiving apparatus is in a predetermined range;
a division unit configured to divide, if it is detected that the second power receiving apparatus is in the predetermined range before elapsing a predetermined time period since it is detected that the first power receiving apparatus is in the predetermined range, the first power receiving apparatus and the second power receiving apparatus into a first group;
an acquisition unit configured to acquire first information indicating a remaining capacity of a first battery charged by the first power receiving apparatus from the first power receiving apparatus, and to acquire second information indicating a remaining capacity of a second battery charged by the second power receiving apparatus from the second power receiving apparatus; and
a communication unit configured to transmit, if the first group is selected and the remaining capacity of the first battery is smaller than the remaining capacity of the second battery, a first command to the first power receiving apparatus, and to transmit a second command to the second power receiving apparatus,wherein the first command includes a command used for instructing to execute charging, andthe second command includes a command used for instructing to stop charging.

Abstract
If a plurality of power receiving apparatuses are in a predetermined range, a power supply apparatus selects a power receiving apparatus to be preferentially charged based on the remaining capacities of batteries of the respective power receiving apparatuses, and stops charging of the power receiving apparatuses other than the selected power receiving apparatus until the remaining capacity of the selected power receiving apparatus reaches a predetermined value.
