N2 - Lithium-ion batteries have been widely adopted in new energy vehicles containing two-step charging processes, i.e., constant current (CC) charging stage and constant voltage (CV) charging stage. Currently, the conventional magnetic resonance wireless power transfer (WPT) structure only has one single output mode, which affects the charging speed and lifetime of the energy storage device. To address the aforementioned issues, a novel solid-state switch-altered-based wireless power charging system is proposed to freely change the output mode of the receiving end by turning the AC Solid-State switch in this paper. The output characteristics of the LCC-LCC-type and proposed LCC-LCC-π-type system are compared in detail. Then, the coupling coefficient and distribution of the magnetic field cloud in the self-designed magnetic coupling mechanism are analyzed by finite element analysis. Simulation verifies the feasibility of the proposed WPT-based charging system with solid-state switches for charging mode switching, which further improves the charging performance of energy storage devices.
