Abstract:
Aiming at the complex electromagnetic environment in the working process of wireless charging piles for electric vehicles,the paper studies the electromagnetic characteristics of the inverting part and the coupling coil of the magnetic coupling resonant wireless charging pile,gives the theoretical derivation of the electric field strength of the magnetically coupled resonant coil,models the magnetic coupling coil by FEKO simulation software,and analyzes the electric and magnetic field strengths. Findings can be obtained that the electric field and magnetic field distribution of the coil exhibit a certain symmetry,and that the symmetry is more obvious in the electric field. At the center of the transmitting coil,both electric and magnetic fields reach peak levels. From the transmitting coil to the receiving coil,the electromagnetic field first decreases and then increases.
