Magnetic Resonance Coupling Modelling for Electric Vehicles Wireless Charging

摘要

Due to the fast-growing market for the electric vehicle, it is necessary that the drawbacks involved in it should be overcome, therefore introducing wireless charging technique which is more convenient as battery cost, recharge time and weight has been removed. Different wireless charging techniques for electric vehicles are discussed. The feasibility of wireless power transfer for Electric Vehicles by electromagnetic resonance coupling is modelled in this paper. Wireless power transfer (WPT) for Electric Vehicles by magnetic resonance coupling is of high priority due to its efficiency, high power transmission and larger charging distance. Also, we demonstrated with simulations how energy can be transferred efficiently between two magnetically coupled resonating coils. Also, the effect of parameters such as the inductor, capacitor, load, and coupling coefficient on efficiency are also discussed.
