Modelling and performance analysis of electric vehicle

Abstract

Conventional vehicles utilise petroleum-derived fuels for providing good performance and long-range speed. Due to the utilisation of petrol or diesel, there are few disadvantages such low fuel economy and exhaust gas emissions, which cause environmental pollution. To overcome such problems, this paper addresses the designing of an electric vehicle model, to enhance energy efficiency, reduce emissions, high-performance and low-maintenance. A simple and low run-time electric vehicle is modelled using simscape components using MATLAB. The dynamic model was used with the drive cycle source, battery, driver controller, power converter, motor, and vehicle subsystem. The power converter is designed using H-bridge with regenerative braking. The vehicle?s kinetic energy is recovered by braking the electric motor in the generator mode. Performance parameters, such as vehicle speed, current, State of Charge (SoC), motor RPM and distance, are verified with various drive cycles. The distance travelled, speed and torque by the electric vehicle are obtained using the simulation model and results are analysed.
