| dc.description.abstract | The increasing global demand for sustainable transportation has accelerated the adoption of electric vehicles (EVs). However, the widespread use of plug-in charging systems poses challenges such as connector wear, user inconvenience, and safety hazards. To overcome these limitations, contactless or wireless electric vehicle charging has emerged as a promising alternative that enables energy transfer without physical connections. This project explores the design, working principles, and implementation of a stationary inductive wireless charging system based on the SAE J2954 standard. The system operates through electromagnetic induction between a ground-based transmitter coil and a receiver coil mounted under the vehicle. Power is transferred across a small air gap, converted from alternating current (AC) to direct current (DC), and delivered to the vehicle’s battery with high efficiency ( 90 A comprehensive literature survey was conducted to evaluate existing wireless power transfer (WPT) technologies, compensation topologies, alignment methods, and electromagnetic compatibility (EMC) considerations. Based on these findings, a proposed system was developed featuring power electronics, coil assemblies, alignment guidance sensors, and control mechanisms for safe and efficient energy transfer. The implementation details include system architecture, inverter design, coil alignment strategies, and protective circuitry to prevent overcurrent, overheating, and misalignment hazards. Results and research analysis confirm that wireless charging can achieve comparable efficiency to wired systems while enhancing convenience and safety. The project concludes that stationary contactless charging is a viable near-term solution for residential and shared parking facilities, while future work should focus on higher power transfer levels, dynamic charging (on-road), bidirectional energy flow, and cost optimization for large-scale deployment.
