Simulation-Based evaluation of dynamic wireless charging systems for electric vehicles: Efficiency, limitations, and future directions

The increasing focus on environmentally sustainable technologies has catalyzed significant advancements in electric vehicles (EVs), marking a pivotal shift in the transportation industry. Among these developments, wireless charging technology for EVs has emerged as a transformative innovation, attracting substantial interest in research and development. These advancements aim to reduce greenhouse gas emissions, establish EVs as a primary mode of transportation, and contribute to a more sustainable future. Electric vehicles are generally categorized into hybrid and pure electric types. Hybrid EVs combine internal combustion engines with onboard energy storage systems for propulsion and charging, serving as an intermediate step toward full electrification. In contrast, pure EVs rely entirely on external energy sources, necessitating the use of dedicated charging infrastructure. Despite the widespread adoption of conductive charging methods, they face challenges such as reliance on physical connections, which can be cumbersome and inefficient. Wireless charging, particularly through contactless power transfer (CPT), has demonstrated significant potential to overcome these challenges. This technology offers key benefits, including higher efficiency, tolerance to misalignment, and reduced charging times, positioning it as a viable alternative to conventional charging methods. Recent advancements, driven by extensive research, have further enhanced the practicality and efficiency of wireless charging systems. This study investigates dynamic wireless charging systems for EVs, addressing the critical need to reduce environmental impact and enhance charging convenience. It utilizes simulations to analyze the performance of dynamic charging systems employing resonant inductive power transfer technology under real-world conditions. Variations in parameters such as alignment and gap are examined to provide insights into system performance and optimization. The findings of this research aim to advance the development of wireless charging technology, emphasizing its potential to revolutionize the transportation sector. By addressing existing challenges and offering innovative solutions, this study contributes to the pursuit of sustainable and efficient mobility systems.
