A new wireless charging system for electric vehicles using two receiver coils

This paper presents, the dynamic wireless power transfer is a practical method to solve electric vehicle range anxiety and reduce the cost of on board batteries. Wireless recharging has long been common with pure electric vehicles and is designed to allow charging even when the vehicle is in motion. However, it is difficult to analyse this method since its operating philosophy is complex, particularly with the existence of several variables and parameters. Also, the state of the vehicle, whether it is in motion or not, defines several parameters such as the vehicle speed as well as the sizes and dimensions of the coil receivers.   A novel method to improve the performance of the dynamic wireless recharge system. In the proposed system, receiver coils have been added to maximize charging power by offering a dynamic mathematical model that can describe and measure source-to-vehicle power transmission even though it is in motion. In the proposed mathematical model, all physical parameters describing the model were presented and discussed. The operation of wireless charging of the battery through two receiver coils is validated by performing several simulations in MATLAB/SIMULINK software.
