Power transmitting apparatus, method of controlling the same, and power transmission system
First Claim
1. A power transmitting apparatus comprising:
- a first antenna configured to perform wireless power transmission to a power receiving apparatus and perform wireless communication with the power receiving apparatus;
a second antenna configured to perform wireless communication with the power receiving apparatus, wherein the second antenna is different from the first antenna; and
one or more processors configured to;
communicate with the power receiving apparatus, by the first antenna, identification information of at least one of the power transmitting apparatus and the power receiving apparatus, wherein the identification information can be used for communicating by the second antenna;
determine whether or not a communication connection based on the identification information that is communicated by the first antenna is established via the second antenna;
perform wireless power transmission to the power receiving apparatus by the first antenna based on a determination that the communication connection based on the identification information that is communicated by the first antenna is established via the second antenna, and; and
restrict wireless power transmission to the power receiving apparatus based on a determination that the communication connection based on the identification information that is communicated by the first antenna is not established via the second antenna.

Abstract
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.
