Wireless Charging for Electric Vehicles

This research paper presents a comprehensive scientific and engineering analysis of wireless charging technologies for electric vehicles, positioning them as a significant advancement in future mobility systems. The study addresses key limitations of conventional conductive charging, including mechanical wear, dependence on user intervention, limited suitability for autonomous vehicles, and challenges related to infrastructure scalability. Adopting a systems-level perspective, the paper examines wireless power transfer from fundamental electromagnetic principles through practical vehicle and infrastructure integration. The research covers inductive and resonant charging physics, magnetic field behavior, misalignment effects, shielding strategies, power electronics architectures, control methodologies, efficiency mechanisms, and thermal management considerations. It further evaluates safety aspects, electromagnetic compatibility, human exposure limits, grid interaction, reliability engineering, and manufacturing scalability. A structured comparison with conventional wired charging highlights both performance trade-offs and operational advantages. The findings indicate that although wireless charging currently faces efficiency and cost challenges, it offers substantial benefits for autonomous vehicles, fleet operations, and urban mobility, positioning it as a foundational technology for next-generation electric transportation.
