In this paper, the structure and working principle of the magnetically coupled resonant radio energy transmission system for electric vehicle are briefly introduced. Then, according to Biot-Savart Law, the magnetic field generated by the energy emission coil in the wireless charging system is deduced, analyzed and calculated in detail. Finally, the distribution of the magnetic field intensity generated by the emission coil is obtained. This provides a theoretical reference for the positioning requirements between the transmission coil and the receiving coil in the wireless charging system of EV.
