Original Abstract Submitted
A power transmission apparatus configured to wirelessly transmit power to a power reception apparatus executes, when wirelessly transmitting power, detection processing for detecting an object different from the power reception apparatus, using a power loss, obtains, from the power reception apparatus, reference value information regarding a reference value of received power used to obtain the power loss, and performs a specific control after the power loss has been obtained and in a case where a predetermined time has elapsed since a predetermined timing associated with a timing at which information is obtained from the power reception apparatus, without obtaining the reference value information that is valid, the specific control being a control to prevent a power transmission output from being increased, regardless of received power in the power reception apparatus.
