Summary:This paper deals with the numerical simulation of a flexible wireless high power system for charging the batteries of electric vehicles. The key component that ensures the contactless power transfer and interoperability is the inductive coupler. Its parameters depend on the transmitter and receiver coils structure, magnetic cores material and shape, distance between them etc. The parameters of the inductive coupler were determined by a 3D finite element analysis using Flux® software package and they were further used for numerical simulation of the entire charging system using Matlab/Simulink® environment. The numerical simulations were carried out for battery charging of a heavy duty electric vehicle (e.g. electric bus or truck) and of a commercial electric vehicle. Stray fields were also computed to verify their compliance with the values imposed by international standards.
