Design and Development of a Wireless Charging System for an Electric Two-Wheeler

Abstract

Wireless Power Transfer (WPT) has emerged as a reliable alternative to conventional plug-in charging systems for electric vehicles due to improved safety and user convenience. This paper presents the practical design and hardware implementation of a resonant inductive wireless charging system developed for an electric two-wheeler. The system operates from a 230 V, 50 Hz AC input supply, stepped down to 13.79 V AC using a transformer and rectified to 17.49 V DC. A regulated DC stage feeds a high-frequency inverter generating approximately 70 V AC in the 60–80 kHz range to energize the transmitter coil. The receiver coil output is rectified and filtered to obtain a stable 12 V DC suitable for battery charging. Experimental results validate the theoretical rectifier calculations and confirm stable wireless power transfer performance. The developed prototype demonstrates the feasibility of a compact and cost-effective wireless charging solution for electric two-wheelers.
