The invention relates to a wireless charging interoperation system performance authentication method. A circuit impedance model of a wireless charging interoperation system is established to obtain afirst authentication target and a second authentication target from the circuit impedance model. The first authentication target value and the second authentication target value are changed along withthe change of a device variable parameter of the wireless charging interoperation system. Secondly, equipment fixed parameters of the wireless charging interoperation system are acquired, target power of the wireless charging interoperation system is estimated, and further a first authentication interval and a second authentication interval are acquired. When the first authentication target valueis located in the first authentication interval and the second authentication target value is located in the second authentication interval within the value range of the device variable parameter, itis judged that the wireless
