Abstract: There is a developing for electric vehicle (EV) because of their lower fuel and greenhouse gas. Wireless power transfer (WPT) is easy to use ways to recharge, but the problem with the current wireless charging technology for electric vehicle are low efficiency and slow charging time. This paper presents the design parameters of permeability and conductivity in various material of the transmitter and the receiver which performs in the partial differential equation. The paper simulation using 3-D finite element method that all the coded developed by MATLAB program and show the graphical representation for the magnetic field of the WPT.

Keywords: Wireless charging, wireless power transfer (WPT), magnetic field, electric vehicle (EV), 3-D finite element method (3-D FEM)
