| Abstract |
Electric vehicles (EVs) charging by static wireless charging is growing in popularity worldwide.Wireless charging technology for electric rickshaws (e-rickshaws) has emerged as a promising solution to overcome the limitations of conventional wired charging systems, such as physical wear, safety concerns, and charging downtime. This study explores and compares single-phase and three-phase wireless charging systems for e-rickshaws, focusing on their operational principles, efficiency, and suitability for urban transportation. The single-phase wireless charging system, characterized by its simpler design and cost-effectiveness, is ideal for light-duty e-rickshaws operating in low-power scenarios. However, it often suffers from lower power transfer efficiency and slower charging rates. On the other hand, the three-phase wireless charging system offers higher power transfer efficiency, faster charging times, and better scalability for heavy-duty applications, though it comes with increased complexity and cost.By analyzing the design challenges, electro-magnetic interference issues, and overall performance of both systems, this study highlights the trade-offs between efficiency and cost-effectiveness. Furthermore, the feasibility of integrating wireless charging systems with renewable energy sources and their potential role in developing sustainable, smart cities is discussed. The findings serve as a foundation for selecting and optimizing wireless charging technologies tailored to the specific needs of e-rickshaws in different settings.It also presents the results of Single phase and three-phase sources based SWCS with a 40% coupling coefficient at 85KHz switching frequency. The overall comparison analysis was done by using LTSpice software. © 2025 IEEE. |
