The invention relates to the technical field of wireless electric energy transmission and particularly discloses a cross coupling suppression structure and method in a guide rail type wireless electric energy transmission system, an energy transmitting end adopts a multi-section guide rail type wireless energy transmitting coil structure, and a plurality of wireless energy transmitting coils are sequentially and horizontally arranged in the length direction; and the current directions are arranged in the same phase; an auxiliary coil is arranged in each wireless energy transmitting coil, the current direction of each auxiliary coil and the current direction of a corresponding wireless energy transmitting coil are arranged in the same phase, and the coupling effect between each auxiliary coil and the corresponding wireless energy transmitting coil is opposite to the coupling effect between every two adjacent sections of wireless energy transmitting coils. The method has the advantages that a compensation coil
