The tram super capacitor charging rail power supply system pioneers the station type overhead charging rail device. The platform type overhead steel aluminum composite charging rail is used to transmit electric energy to the capacitor. The vehicle can quickly charge and store energy within 30 seconds in the platform area, so as to realize the train line running without catenary, with good overall landscape, energy saving and environmental protection The operation and maintenance work quantity is small, which is mainly used in the main line station, parking garage and maintenance depot of urban rail transit.
