A Parallel Transmission of Power and Signal Based on The Combination of Inductance and Capacitance for EV Dynamic Wireless Charging System

This paper proposes a method for parallel transmission of power and signals suitable for electric vehicle (EV) dynamic wireless charging. In essence, data is transmitted through the high-frequency electric field of the parasitic capacitance between the transmitting coil, the receiving coil and the shielding plate of the receiving end, and power is transmitted through the magnetic field of relative frequency generated by the coupling coil. In this paper, the coupling mechanism and working principle are expounded and explained, and the parameter design method of the system is given. In addition., the interference between the power wave and the data carrier is also analyzed. Finally, the simulation of the system is carried out, and the parallel transmission of power and signal in the dynamic charging of electric vehicles is realized.
