Power transmitting apparatus, power receiving apparatus, control method therefor, and storage medium

Abstract

A power transmitting apparatus sets, on the basis of transmission power set with the power receiving apparatus, a first threshold for determining whether or not a foreign object exist, and a second threshold lower than the first threshold. The first and second threshold are set so that the difference between the first and second threshold values becomes larger as the set transmission power becomes larger. The power transmitting apparatus determines: that a foreign object exists in a case where the power loss is greater than the first threshold; that a foreign object does not exist in a case where the power loss is less than the second threshold; and that there is a possibility of a foreign object existing in a case where the power loss is between the first threshold and the second threshold.
