INTEGRATED DYNAMIC BIDIRECTIONAL ROADWAYS ELECTRICAL VEHICLE POWER TRANSFER SYSTEM

Abstract

The escalating global energy demand and the imperative for sustainable transportation solutions necessitate a paradigm shift in energy infrastructure, with Electric Vehicles (EVs) emerging as a cornerstone of this transformation. Conventional wired EV charging, however, presents limitations including energy losses, inconvenience, and aesthetic drawbacks. This research addresses the critical need for an integrated, efficient, and bidirectional power transfer system for EVs, capable of both charging from the grid or renewable sources and feeding power back to the grid (Vehicle-to-Grid, V2G), particularly within a dynamic roadway context. The primary objectives encompass a comprehensive study of wireless power transfer (WPT) techniques and Maximum Power Point Tracking (MPPT) algorithms, the development of simulations for a solar-based bidirectional wireless EV charger, the implementation of a prototype hardware for a contactless bidirectional EV charging unit utilizing resonant inductive coupling, and the rigorous validation of the hardware results. The proposed system integrates solar photovoltaic (PV) power generation with MPPT, advanced bidirectional power converters, and resonant inductive coupling for efficient and secure energy exchange. Key findings indicate the system's potential to significantly minimize transmission losses and combat electricity theft through wireless means. It aims to maximize energy efficiency and utilization by seamlessly integrating renewable sources, while enhancing grid stability and resilience through V2G functionality, allowing EVs to serve as mobile energy storage units. Furthermore, the system is designed to improve user convenience and alleviate range anxiety for EV owners. This research contributes significantly to the advancement of sustainable mobility, grid resilience, and the development of intelligent transportation and energy infrastructure for future smart cities.
