Technological development related to sustainable mobility and the growing of environmental concern has demanded the attention of researchers who investigate the electrification of transport. In this sense, the battery autonomy is one of the main limitations in electric vehicles, together with their energy charging techniques. Currently, the conductive charging method is the most widespread on the market, however, it presents safety and practicality concerns to users. Therefore, the implementation of new strategies, such as wireless energy recharging, can be a solution to the aforementioned difficulties. In this context, this study presents the analysis, design and development of an inductive coupling for wireless power transmission with focus on electric vehicles charging systems. For this, a methodology for designing the inductors is proposed based on the previous parametric specification of the electrical system to which the magnetic coupling will be part. The results of the coil simulation are presented together with the finite element analysis software Ansys Maxwell 3D, allowing variations in distance and misalignment between inductors, in addition to their interaction with the electrical circuit on the Simplorer platform. Finally, a practical and experimental verification of the inductive system with the proposed electrical circuit is carried out.
