The invention belongs to the technical field of wireless power transmission equipment, and discloses an array type wireless power transmission transmitting coil, a design method and application. Calculating the distance when the mutual inductance of the transmitting coil is zero in the offset process through Maxwell; and designing the distance of the overlapped part of the two coils according to the calculated distance. When the overlapping distance of the double-coil model is 62 mm, the mutual inductance between the coils is zero. According to the calculation result, a 2 * 2 array coil model is designed, and a 3 * 3 array transmitting coil model is further designed. The key technical problems that in the prior art, the arrangement mode, the connection mode and the switching control strategy of multiple coils are not solved are solved. The key problems that in the prior art, mutual coupling between transmitting units of an array type transmitting coil is reduced, and array type wireless power transmission is achieved are solved.
