The invention discloses a coil magnetic core structure in an electric vehicle wireless charging induction power transmission system. The coil magnetic core structure comprises a magnetic core and coils, the magnetic core is formed by symmetrically splicing two I-shaped structures on the two sides in parallel, and the coils are wound around each I-shaped structure; in the two I-shaped structures, bottom plates are located on the same plane and integrally formed, top plates are located on the same plane, and the size of the top plates is smaller than that of the bottom plates. The coil magnetic core structure has a higher coupling coefficient, so that the mutual inductance of a receiving coil and a transmitting coil is higher, the transmission power can be greatly improved under the condition of maintaining high efficiency, the size of each part is adjustable, and the coil magnetic core structure has adaptability to different application scenes.
