Abstract
With the rapid development of new energy vehicles, traditional wired charging methods are facing challenges in terms of safety and convenience, while wireless charging technology has become a research hotspot because of its convenience and security. In this paper, the wireless charging system of electric vehicle is taken as the research object, and the wireless charging system with RLC series resonant circuit as the core is designed. In this paper, the basic principle and characteristics of the resonant circuit and the working principle of the coil are analyzed. The corresponding circuit structure is designed, and the performance of the system 's power transmission is verified by simulation. The simulation results show that the system has high power factor and transmission efficiency in the resonant state, which verifies the feasibility of the design and provides a reference for the design and optimization of the wireless charging system for electric vehicles.
