PROBLEM TO BE SOLVED: To provide a noncontact electric supply system for a railway vehicle, which provides noncontact electric supply without changing conventional equipment with the simple structure, in which an electric supply coil is installed between rails on the ground side, and an electric collection coil is installed on a vehicle side, and a rail heating amount is also reduced. SOLUTION: The noncontact electric supply system for a railway vehicle is provided with: an electric supply coil 3 with figure of eight arranged between rails 2 and 2' installed on a track A; a high frequency wave supply source 1 for supplying electricity to the electric supply coil 3; an electric collection coil 6 with figure of eight arranged on the bottom of a railway vehicle 4 traveling on the rails 2 and 2', and facing the electric supply coil 3 with figure of eight when the railway vehicle travels; a converter 7 connected to the electric collection coil 6; and a rechargeable battery 8 connected to the converter 7. Output from the electric collection coil 6 is charged to the rechargeable battery 8 by relative movement of the electric collection coil 6 to the electric supply coil 3. COPYRIGHT: (C)2010,JPO&INPIT
