The invention provides a multistage induced electric field type wireless electric energy transmission system and method and a railway vehicle. The system comprises a power supply and at least one bilateral CL compensation topology circuit. The power supply transmits electric energy to each load step by step through the bilateral CL compensation topology circuit, and the loads output at constant voltage and do not influence each other. Wireless power supply can be simultaneously carried out by a single power supply and multiple loads, cable connection is not needed, and the problems of cable abrasion, plug falling and the like caused by a traditional wired power supply mode are effectively avoided. 本发明提供了一种多级感应电场式无线电能传输系统、方法及轨道车辆，包括：电源及至少一个双边CL补偿拓扑电路；电源通过双边CL补偿拓扑电路将电能逐级传递至各负载，各负载间恒压输出且互不影响。可实现单电源多负载同时进行无线供电，无需线缆连接，有效避免了传统有线供电方式带来的线缆磨损、插头脱落等问题。
