Abstract [en]

In order to improve its electric vehicles, Renault, the French car manufacturer, focuses on reaching to main targets : first, the autonomy of the electric car and then, its global cost. In the first part, a way of reducing the losses that are created in an inverter is presented. By simulating a charger and especially the inverter that is used, the different types of losses will be exposed and some leads to make them decrease will be revealed. And the reduction of these losses will eventually lead to the increase of the autonomy of the vehicle. Then, in an attempt to develop new technical solutions for the electric car, a new solution will be presented : the resonant charger. This new technical solution will be explained, analysed and then used in simulations. The results obtained through these simulations will be key elements in formulating some challenging conclusions and to know if it could represent a good way to reduce the global cost of the electric vehicle.
