Modelling of Electric Vehicles Using Matlab/Simulink 2020-01-5086
In this paper, we present a Matlab/Simulink model for electric vehicles (EVs). We model the vehicle dynamics, transmission performance, and battery of the EVs to acquire the power requcirements of the battery and to later deduce the best types of battery to use for such applications. The simulations are performed through an integration of the Matlab code and Simulink blocks. The velocity of the vehicle and its distance travelled correspond to actual driving cycles and torque variations of an EV. The added value of this model is that it simulates the aerodynamic drag, linear acceleration, and rolling resistance forces where the modelled motor efficiency hit 73%. Other results corresponding to its tractive effect, motor efficiency, and battery requirements are obtained. The simulations are verified and all fit the theory behind EVs.
