Abstract

Industry roadmaps state that electric vehicles (EVs) will play a key role in automotive power systems technology going forward. Major global manufacturers are currently putting a lot of concentration on EVs because they are predicted to drastically change the road transport sector. As of mid-March, Malaysia had sold up to 192,474 electric vehicles this year. Selecting a motor and battery size appropriate for the e-buggy's usage is crucial to the project. The objective of this project is to create a mathematical model of an electric vehicle using MATLAB-Simulink. Therefore, MATLAB simulation may be used to evaluate the ebuggy's performance based on the battery and motor configuration. There are differences in the performance and range of different battery types. MATLAB-Simulink will be used in this project to design an electric vehicle system with three subsystems. There are three subsystems: battery, inverter, and motor mechanical. The controller and the measurement, which are external components, are the other two subsystems in the electric vehicle system. The controller's responsibility is to control each subsystem, whereas the measurement's is to collect data and present a graph. The vehicle parameter will be set as closely as is practical based on the actual vehicle parameter. As a result, it is feasible to measure an electric car's voltage and current. In this project, parameters from the verification model and the new ebuggy model will be used to compare the voltage and current data from MATLAB-Simulink. Parameter fine tuning will be done until a correlation of more than 80% is obtained with the verification model. To sum up, the project's objective was to suggest and create a MATLABSimulink model for an electric vehicle system, then compare the new e-buggy's mathematical model with the verification. In the process, important car characteristics that have a bigger influence on the e-buggy's performance were also identified.
