DESIGN AND DEVELOPMENT OF AN INTEGRATED DRIVE AND CHARGING SYSTEM FOR ELECTRIC VEHICLES

Abstract

The objective of this project is to construct and refine an integrated drive and charging system for electric vehicles, thereby integrating propulsion and charging operations into a single power electronics architecture. The proposed solution reduces costs, saves space, and streamlines the system by utilizing shared components such as the inverter and motor windings to manage both on-board charging and traction. The system is capable of transitioning between driving and charging modes with minimal degradation in power quality, reliability, or efficiency through the use of advanced control algorithms. The integration also enables bidirectional power transfer in vehicle-to-grid (V2G) applications, which improves energy management and reduces the necessity for supplementary hardware. The system that has been developed is a viable alternative for next-generation electric vehicles, as it outperforms conventional separate propulsion and charging systems while consuming less energy, as demonstrated by experimental and simulation results. Additionally, it is more compact and diminutive.
