Wireless Train: Wirelessly Charged High-speed Train Successful in Test Run | BusinessKorea

The commercialization of a high-speed train with a wireless charging system is expected to be realized in 4 to 5 years.

The Korea Railroad Research Institute (KRRI) showcased its technology for wireless power transmission used in a high-speed at a railroad museum near Seoul on May 20.

KRRI successfully tested a method that wirelessly transmits 1MW of electricity using 60 kHz to the bottom of a high-speed train for power.

Dr. Lee Joon-ho at KRRI remarked, “If this technique is applied to a light train that uses 300 to 600 kW, it can be commercialized within 4 to 5 years.” Lee added, “To commercialize the method in a high-speed train that can move at 300 km/h, we are planning to conduct an additional study aimed at increasing the space between a collector plate and a feed line from 3 cm to 8 cm.”
