Power transmitting apparatus, power receiving apparatus, control methods therefor, programs, and storage medium
First Claim
1. A power transmitting apparatus that transmits electric power to a power receiving apparatus, the power transmitting apparatus comprising:
- a first power transmitting unit configured to transmit, to the power receiving apparatus, first type of electric power having a first power value and second type of electric power having a second power value different from the first power value;
a second power transmitting unit configured to transmit electric power having a third power value which is larger than the first power value and the second power value;
a communication unit configured to perform wireless communication wherein a communication range of the communication unit is wider than electric power transmittable range of the first power transmitting unit and the second power transmitting unit; and
a determination unit configured to determine whether the power receiving apparatus is the destination of power transmission by the second power transmitting unit based on power transmissions with the first type of electric power and the second type of electric power by the first power transmitting unit and communication by the communication unit.

Abstract
A power transmitting apparatus that transmits electric power to a power receiving apparatus performs wireless communication with the power receiving apparatus, transmits at least one type of electric power having a power value specific to the power transmitting apparatus, and performs a determination as to whether or not to transmit electric power required by the power receiving apparatus to the power receiving apparatus. The power transmitting apparatus receives at least one type of converted value converted from the electric power received by the power receiving apparatus, and performs the determination based on the converted value and the specific power value.
