Dynamic Modeling of a Micro Solar Electric Vehicle for Pakistan using Simulink

Abstract

While the global electric vehicle (EV) adoption is on rise, developing countries like Pakistan have been facing many obstacles in the face of EV adoption such as shortfall of electricity, high EV prices, low average income and absence of commercial and residential charging infrastructure. In this paper, we propose a design of a micro solar electric vehicle, which would help overcome all of these problems and provide an economical yet feasible solution. The design and system sizing of the micro solar EV was done in HOMER Pro. A dynamic model of the micro solar EV was created in MATLAB/Simulink, which implemented PV generation, maximum power point tracking, battery charging and discharging, DC-motor operation and speed control of the electric vehicle, while taking into consideration environmental factors like irradiance and temperature.
