3. INTRODUCTION The imminent shift to electric vehicles creates a market gap for advanced charging solutions. Currently, 90% of the industry uses plug-in hybrid electric vehicles (PHEVs) due to inefficiencies and infrastructure challenges with wireless charging . Recent research has focused on off-grid and hybrid EV charging systems to enhance adoption in areas with unreliable or absent electrical grids, aiming to ensure seamless infrastructure in both urban and rural areas. This project aims to combine 2 innovative and trending techniques together (i.e. hybrid and wireless charging stations ) in order to build a new marketable product . We focused on E-Bikes as our ( load ) application in order to achieve our project goals. Wireless power transfer is a leading strategy, though efficiency issues need resolution. We focus on improving efficiency and use resonant inductive coupling to achieve this. 9/2/2024 3 FYP Proposal Defense (Fall 2021 Batch) Electrical Engineering Department
