Abstract: Dynamic wireless charging (DWC) technology will become an important technical means to solve the "range anxiety" and "difficulty in charging" problems of electric vehicles, but its rapid development is limited by high construction cost and impact of power grid. Therefore, based on the analysis of the problem by theory of the solution of inventive problems (TSIP) innovation method, this paper proposes a segmented dynamic wireless charging system to solve the existing problems. Segmented dynamic wireless charging system effectively solves the existing problems of dynamic wireless charging technology through segmented construction, equipment sharing, solar power generation, energy storage and other technologies. Through the feasibility verification of the prototype, this paper proves that the segmented wireless charging technology can meet the development of the future dynamic wireless charging technology and solve the problems faced by the future popularization of electric vehicles.
