The invention discloses an asymmetric electromagnetic coupler suitable for a wireless charging device. The asymmetric electromagnetic coupler comprises a reception assembly and an emission assembly which are oppositely arranged with an interval, the reception assembly and the emission assembly are different in materials of foundations, other structures of the reception assembly and the emission assembly are the same, an inner chamber of the foundation is sequentially disposed with a magnetic film, a magnetic stripe positioning board and a coil limit board, an array magnetic stripe is arranged in a rectangular groove of the magnetic stripe positioning board, a coil is arranged in a groove of the coil limit board, an upper cover board covers the position, and a screw penetrates through a through hole on the cover board and a through hole on a foundation projection and is then connected with an upper nut. Through the asymmetric electromagnetic coupler, influence of eddy current of an aluminum board foundation of a traditional coupler can be reduced, a coupling coefficient and a quality factor are improved, a designed bar-shaped magnetic stripe array disposing mode can enhance lateral offset margin of the asymmetric electromagnetic coupler, and the asymmetric electromagnetic coupler is more suitable for wireless electric energy transmission of electric automobiles.
