Abstract
This works develops a simulation model to predict the performance of direct current electric motors for electric vehicles (EV), mainly focused on the required power and mechanical torque as a function of the driving conditions. The simulation, therefore, has been based on the dynamic conditions of the electric vehicle to reproduce the current driving in urban routes or intercity travels. The model has been applied to synchronous and asynchronous transmission system. The results has proved that the performance of an electric vehicle engine can be predicted using characteristic parameters of the driving like the acceleration rate and vehicle speed, as well as of the environmental conditions, such as wind force and tire to road friction. The aerodynamic profile and the mass of vehicle have also been included in the simulation predictive model. The simulation has proved that there is not a unique option that makes the electric motor working better in all conditions, since in some cases is the synchronous transmission which generates higher performance, while in other cases is the asynchronous. At the acceleration mode, either in flat terrain or in ramp or descent road, the synchronous transmission system is more suitable, while for constant speed in flat terrain the asynchronous transmission works better, as well as at constant speed in ramp or descent road.
Keywords: Electric vehicle. Engine performance. Power simulation. Synchronous and asynchronous transmission system.
