Modelling and simulation of a commercial electric vehicle

The introduction of electric propulsion chains in automobiles has been contributing to reduce fuel consumptions and optimize the efficiency of commercial vehicles. In this paper, the dynamic behavior of a commercial electric vehicle is simulated and analyzed. The dynamic behavior of the available electric vehicle (Fiat Seicento Elettra) was simulated using two different approaches to the mechanical modeling: one using a detailed approach for the mechanical parameters and forces applied to the vehicle chassis and the other, only based on the typical forces applied to a body representing this type of vehicle. The results obtained, allowed to validate the mechanical model based on the forces applied to the vehicle and to analyze the behavior of the electric power chain for the vehicle typical operation modes: start, braking, acceleration, and slowing down together with pathways of variable slope.
