The automotive vehicle market is currently experiencing an advance in the development of electric vehicles, a market trend driven by the technological advancement of this sector and by a need to reduce pollution caused by automotive vehicles. In this way, it is necessary to develop a mathematical and simulation model that is capable of making predictions about the behavior of the vehicle for specific situations. In this work, a model for the powertrain system applicable to electric vehicles was developed, with mathematical models of vehicle dynamics, electric motors and magnetic flux and speed control loop. To this end, a literature review was carried out on such points. The mathematical models developed were used in simulation environments to verify the behavior of the developed control system, as well as the reaction of the powertrain system to specific situations common to the use of electric vehicles. The results show that the mathematical models developed realistically represent the dynamic behavior of electrical machines, as well as the dynamic behavior of vehicles and satisfactory responses of the control loop. Thus, it can be concluded that the models developed meet the requirements proposed at the beginning of the work.
