MAGNETIC COUPLING DEVICE FOR CHARGING ELECTRIC VEHICLE

摘要

PROBLEM TO BE SOLVED: To prevent the size of the gap between primary and secondary cores from varying depending on the insertion state of a primary coil unit. SOLUTION: In an object where a primary coil 30 is inserted and set in the receiver provided with a secondary coil of an electric motorcar, the junction planes of the primary and secondary both cores 21 and 33 are made in the direction of insertion of the primary coil unit 30, and primary and secondary both coils 22 and 32 are provided in the positions where they do not interfere with the opposite sides at insertion of the primary coil unit 30.
