Foreign substance detection can be performed with a simple configuration in a power transmission system. A power transmitting apparatus that wirelessly transmits power to a power receiving apparatus, the power transmitting apparatus comprises: determination means for, in a case where an initial impedance value and the detected output impedance value do not match and there is no change in the output impedance value between before and after the transmission of a predetermined detection signal, determining that a foreign substance is present within a predetermined power transmission range, and, in a case where the initial impedance value and the detected output impedance value do not match and there is a change in the output impedance value between before and after the transmission of the predetermined detection signal, determining that a power receiving apparatus is present within the predetermined power transmission range.
A power transmitting apparatus comprising:
A communication method of a power transmitting apparatus configured to wirelessly transmit power to a power receiving apparatus, the method comprising:
A non-transitory computer-readable storage medium storing a program for causing a computer to execute a communication method of a power transmitting apparatus configured to wirelessly transmit power to a power receiving apparatus, the method comprising:
