Simulation of Graphene Battery and other Battery Technologies in an EV Powertrain

Abstract

The motivation for this work is to find a better and efficient energy storage solution for electric vehicle. It is done by comparing the performance of three different batteries, which are: Lead Acid battery, Li-ion battery and Graphene battery. In this paper, an electric vehicle model is created in Simulink using MATLAB software. The constructed model is based on the existing electric car TATA Nexon EV. Also, unlike the real car the model presented has a different battery pack and the battery parameters such as SOC, current, voltage, distance, velocity, and weight are changed to carry out the comparison between different battery technologies. The model will be simulated to obtain data regarding vehicle performance, energy consumption and range on the new FTP75 test cycle. The obtained know-how will help on later improvements of the electric model regarding methods to improve the vehicle performance and the simulation helps to choose the right powertrain for the vehicle without carrying out any real-life experiments.
