A comparative analysis of energy consumption in conventional and electric vehicles

Most widely used motorised vehicles until now are petroleum-based vehicles. But, environmental concerns, policy change and technological advancements are resulting in steady replacement of the conventional vehicles with electric vehicles (EV). With widespread adoption of EVs, it is a must to compare their performance against conventional vehicles. In this paper, the performance of electric propulsion (EP)-based scooters and internal combustion engine (ICE)-based scooters are analysed in terms of power requirement, torque requirement, energy consumption, and mileage. These scooters are modelled using MATLAB Simulink considering longitudinal vehicle dynamics. For this, drive cycle of Mandya City (Karnataka state) is constructed by gathering speed versus time data by driving a scooter with various rolling resistance coefficients. In addition, a standard signal having constant and zero acceleration, constant deceleration phases is also considered to simulate the models in a hilly region by varying the grade angle. Four popular commercial scooters available in India were modelled.
