An Examination of Energy and Efficiency in Wireless Electric Vehicle Charging Systems Utilizing LCC-LCC Resonance Networks

This electronic document highlights the critical importance of electric vehicles (EVs) in the effort to decrease carbon emissions associated with transportation. Nonetheless, there are ongoing challenges in enhancing the efficiency and practicality of EV charging systems, especially concerning wireless power transfer (WPT). Conventional inductive charging systems are limited by factors such as short operational range and energy losses during transmission. This paper examines the potential of Tesla-Coil technology as a means to increase the efficiency of wireless power transfer in EV charging applications. Tesla-Coils, which are capable of transmitting power over longer distances, are proposed as an innovative method to enhance the range and efficiency of WPT systems. The design of the Tesla-Coil-based system, including its transmitter and receiver components, is elaborated upon, along with its power transfer mechanism. Experimental results demonstrate that Tesla-Coils can achieve energy transfer efficiencies of up to eighty-five percent over a distance of two meters, exceeding the performance of traditional inductive systems. Additionally, the system's reliable performance over extended distances renders it suitable for dynamic charging applications. Future research will concentrate on minimizing electromagnetic interference and integrating this system into existing EV infrastructures. The findings suggest that Tesla-Coils represent a promising alternative to conventional wireless charging systems, facilitating efficient long-range charging for electric vehicles.
