Wireless charging system for electric vehicle

Abstract

The majority of electric vehicle systems are built around a number of modules intended to guarantee the high power and stability of the car on the track. Most of these parts are connected to the charging system. Dynamic wireless power transfer can help alleviate range anxiety in electric vehicles and lower the price of on-board batteries. In this regard, pure electric vehicles have long used wireless recharging, enabling charging even while the car is moving. However, due to the complexity of this method's working methodology and the presence of numerous variables and parameters, analysis is challenging. Also, whether the vehicle is moving or not specifies a number of other factors, including the speed of the vehicle, as well as the coil receivers' sizes and characteristics. The dynamic wireless recharging system’s performance can be enhanced using the unique technique presented in this study. By providing a dynamic mathematical model that can describe and measure source-to-vehicle power transfer even while it is in motion, receiver coils have been added to the proposed system to maximize charging power. All the physical parameters of the model were presented and addressed in the suggested mathematical model. The outcomes demonstrated the viability of the suggested model. Additionally, by placing two coil receivers under the car, the simulation results were validated by experimental testing.
