In the past, the power source used on the JR Tokai SCMaglev car was generating with a gas turbine generator. In 2011, they succeeded in powering while driving (CWD:charge while driving) across a large gap by the JR Tokai proprietary 9.8 kHz phase synchronization technology developed based on technology similar to AGV's wireless power scheme. And the Japanese Ministry of Land, Infrastructure and Transportation evaluated the technology as all the problems for practical use were cleared.Evaluation of superconducting Maglev railway practical technology on on-board power supply by induction current collector Construction of SCMaglev begin and commercial use will start in 2027.SCMaglev construction application, wireless power transfer adopted and total construction cost increase
