Study and simulation of wireless vehicle charging installation in dynamic charging

Abstract

In the contemporary era, the imperative for environmentally friendly technologies has led to the advent and proliferation of electric vehicles (EVs), marking a paradigm shift in the transportation sector. A significant innovation in this domain is the development of electric wireless charging vehicles, which has garnered considerable attention for research and development. The overarching aim of these innovations is to mitigate emissions from conventional vehicles, positioning EVs as the future of transportation, and contributing to a more sustainable world. EVs are predominantly classified into two main categories: hybrid and pure EVs. Hybrid EVs utilize a blend of internal combustion engines and on-board DC sources for both propulsion and charging, offering a transitional technology towards full electrification. Pure EVs, on the other hand, rely solely on external energy sources, necessitating the use of specialized chargers to replenish their batteries. Despite the widespread adoption of conductive charging, this method presents several challenges, including the need for physical connections, which can be cumbersome and impractical. Contactless power transfer (CPT) emerges as a promising solution, showcasing remarkable advancements in efficiency, misalignment tolerance, and reduced charging times. These improvements are the result of extensive research and development efforts, aiming to make wireless charging not just a viable alternative, but a preferred method for EV charging. This thesis delves into the dynamic charging technology of EVs, addressing the urgent need to reduce emissions and waste. The focus is on analyzing wireless vehicle charging installations in dynamic charging scenarios, aiming to simulate real-life situations for a comprehensive understanding and the development of practical solutions. The theoretical background provided is essential for solidifying understanding and ensuring accurate results, forming the foundation upon which practical applications can be built. Simulations play a crucial role in this research, aiming to understand the behavior of a dynamic charging system that utilizes resonant inductive power transfer technology. Through these simulations, the thesis provides valuable insights into how variations in gap and misalignment affect the system’s performance, setting the stage for future developments and optimizations. In conclusion, this thesis serves as a comprehensive guide and research basis for understanding and advancing the technology of electric wireless charging vehicles, with a particular focus on dynamic charging. It underscores the importance of continuous innovation and research in this field to meet the growing demands for sustainable and efficient transportation solutions. The ongoing research and development efforts are crucial for overcoming existing challenges, optimizing system performance and safety, and ensuring the practical implementation of this technology in real-world scenarios.
