The invention discloses an electric vehicle wireless charging interoperability detection method and system, and relates to the technical field of wireless electric energy transmission, and the method comprises the steps: carrying out the impedance analysis of a secondary side, and determining impedance parameters alpha and beta; judging whether the impedance parameter alpha meets a transmission efficiency requirement or not; judging whether the impedance parameter beta meets the transmission power requirement or not according to the transmission efficiency requirement eta comref of the secondary side; and judging whether the interoperability is met or not according to whether the impedance parameter meets transmission efficiency and transmission power requirements or not. The interoperability is detected through the impedance parameters, the test cost can be effectively reduced, and the method has low measurement cost and high universality and safety.
