a control unit that controls an informing unit to inform remaining capacity information indicating a remaining capacity of the battery if it is detected that the power receiving apparatus is moved, wherein the motion information and the remaining capacity information are obtained from the power receiving apparatus.

2. The power supply apparatus according to claim 1, wherein if it is detected that the power receiving apparatus is moved, the informing unit informs the remaining capacity information by using one of character data, audio data, and an icon.

3. A power supply apparatus for supplying electric power wirelessly to a first power receiving apparatus and a second power receiving apparatus, the power supply apparatus comprising:

a detection unit that detects whether or not the first power receiving apparatus is moved based on first motion information associated with a motion of the first power receiving apparatus, and detects whether or not the second power receiving apparatus is moved based on second motion information associated with a motion of the second power receiving apparatus; and

a control unit that controls an informing unit to inform first remaining capacity information indicating a remaining capacity of a first battery if it is detected that the first power receiving apparatus is moved and the second power receiving apparatus is not moved, wherein the first motion information and the first remaining capacity information are obtained from the first power receiving apparatus, the second motion information is obtained from the second power receiving apparatus, the first power receiving apparatus charges the first battery, and the second power receiving apparatus charges a second battery.

4. The power supply apparatus according to claim 3, wherein if it is detected that the first power receiving apparatus is moved and the second power receiving apparatus is not moved, the informing unit informs the first remaining capacity information by using one of character data, audio data, and an icon.

5. The power supply apparatus according to claim 3, wherein the control unit controls the informing unit to inform second remaining capacity information indicating a remaining capacity of the second battery if it is detected that the second power receiving apparatus is moved and the first power receiving apparatus is not moved.

6. The power supply apparatus according to claim 5, wherein if it is detected that the second power receiving apparatus is moved and the first power receiving apparatus is not moved, the informing unit informs the second remaining capacity information by using one of character data, audio data, and an icon.

7. A power supply system comprising:

a power receiving apparatus that charges a battery; and

a power supply apparatus that supplies electric power wirelessly to the power receiving apparatus, wherein the power receiving apparatus includes a motion detection unit that detects motion information associated with a motion of the power receiving apparatus,

the power supply apparatus includes;

a detection unit that detects whether or not the power receiving apparatus is moved based on the motion information and a control unit that controls an informing unit to inform remaining capacity information indicating a remaining capacity of the battery if it is detected that the power receiving apparatus is moved, and the power supply apparatus obtains the motion information and the remaining capacity information from the power receiving apparatus.

8. A power supply system comprising:

a first power receiving apparatus that charges a first battery;

a second power receiving apparatus that charges a second battery; and

a power supply apparatus that supplies electric power wirelessly to the fist power receiving apparatus and the second power receiving apparatus, wherein the first power receiving apparatus includes a first motion detection unit that detects first motion information associated with a motion of the first power receiving apparatus, the second power receiving apparatus includes a second motion detection unit that detects second motion information associated with a motion of the second power receiving apparatus, the power supply apparatus includes;

a detection unit that detects whether or not the first power receiving apparatus is moved based on the first motion information, and detects whether or not the second power receiving apparatus is moved based on the second motion information and a control unit that controls an informing unit to inform first remaining capacity information indicating a remaining capacity of the first battery if it is detected that the first power receiving apparatus is moved and the second power receiving apparatus is not moved, wherein the power supply apparatus obtains the first motion information and the first remaining capacity information from the first power receiving apparatus, and the power supply apparatus obtains the second motion information from the second power receiving apparatus.

9. A method of controlling a power supply apparatus, the method comprising:

supplying electric power wirelessly to a power receiving apparatus which charges a battery;

obtaining motion information associated with a motion of the power receiving apparatus from the power receiving apparatus;

detecting whether or not the power receiving apparatus is moved based on the motion information;

obtaining remaining capacity information indicating a remaining capacity of the battery from the power receiving apparatus; and

controlling an informing unit to inform the remaining capacity information if it is detected the power receiving apparatus is moved.
