Modeling of an Electric Vehicle with MATLAB’s Simulink

Abstract

In this paper, we have done the complete modeling of an Electric Vehicle using MATLAB's Simulink, and with the help of the complete modeling of an Electric Vehicle, we have analyzed the different parameters and ranges of an Electric Vehicle. To determine the power requirements for the battery and subsequently determine the best sorts of battery to employ for such applications, we model the vehicle dynamics, transmission performance, and battery of the EVs.

We model the simple low-run-time Electric Vehicle using MATLAB's Simulink. In this whole model, we used different Simulink components such as Longitudinal Driver, DC Motor, and H-Bridge Converter with Regenerative Braking, Battery, and Vehicle Body. In Regenerative Breaking, the power recovered by breaking the Electric Vehicle is stored because in this case, Electric Motor acts as an Electric Generator.

In this paper, we have analyzed different parameters such as Voltage, Current, State of Charge (SOC), Distance, Speed, and Power Consumption in kWh/km and we have also analyzed all these parameters with their waveforms that are for three different batteries Lithium-Ion, Lead Acid, and Nickel Metal Hydride. We used a DC motor because of its high starting torque, good efficiency, run on DC as well as AC   with a rectifier.

In this study, MATLAB/Simulink was used to develop the dynamic model of an electric vehicle. The electric vehicle's energy consumption values were established. It has been investigated how several parameters affect energy usage and vehicle performance. In this whole paper, we have done the comparison of the different parameters of three different batteries and their distance is calculated.
