Abstract

Electric vehicles are getting more and more attention as the representatives of energy-saving and new energy vehicles. Charging equipments play an very important role in the popularization of Electric vehicles. Wireless charging technology is a novel electric energe replenish mode, and have many attractive properties according to traditional contact charging. In this article, the feature of wireless charging mode was analysised comprehensively, and the solution was put forward that electric vehicle was charged by the mode of magnetically coupled resonance. Against the power requirements of electric vehicles, the key issues of wireless charging technology was analysised,and the influence of different coefficient to the charging efficiency was analysised with the help of simulation, and then this article put forward the optimized design of magnetically coupled resonance system, which has reference value for the research of the electric car radio transmission technology.
