EVs are widely used, as they have become more popular due to sustainability and environmental factors; yet, traditional plug-in-charging infrastructure has numerous disadvantages, such as a long recharge time, poses a threat to user safety, and lacks ease of use. The paper is a modelling and simulation of an electromagnetic wave-based wireless charging station to be used in Electric vehicles. A Series-Series (S-S) inductive resonant coupling system using a topology of 85 kHz was modeled and designed. The mathematical modeling and simulation considered in MATLAB Simulink workspace allowed inclusion of an AC power source, rectifier circuit, transmitter and receiver coils, and a battery load. To determine the effect of circuit parameters on power transfer efficiency, a parametric sweep was carried out to assess the effects of the circuit parameters (inductance, compensation capacitance, mutual inductance, on-resistance diodes, and the distance between the coils) on the power transfer efficiency. The simulation findings indicate that the highest efficiency of 98.22 was achieved when the machine was operating under nominal conditions. Sensitivity and correlation analysis indicate that the primary-side inductance and capacitors of compensation have the most impact on the system performance. These results indicate the efficiency of the suggested model of wireless charging and the possible safety, efficiency, and convenience of EV charging infrastructure integration. Compared to standard research on infrastructure planning or inductive charging design, this paper is a comprehensive efficiency-based parametric and sensitivity analysis of an electromagnetic wave-based EV charging system.
