CHARGING SYSTEM FOR ELECTRIC MOTOR CAR

摘要

PROBLEM TO BE SOLVED: To improve cooling efficiency of a primary coil and a secondary coil. SOLUTION: A primary coil unit 60 and a secondary coil unit 20 are constituted by winding conducting pipes 34, 24 around both cores 33, 21. A supply pipe 42 installed in a charging power cable 40 is directly connected with the conducting pipe 34 of the primary coil unit 60 hous in a charging coupler 30. A linkage pipe 27 is linked with the conducting pipe 24 of the secondary coil unit 20. A male joint 28 is fixed to the end portion of the linkage pipe 27. When the charging couple 30 is set in an acceptor part 12, the male joint 28 is linked with a female joint 39 installed in the coupler 30, and so linked with the conducting pipe 42 installed in a charging power cable 40. Thereby the primary and the secondary coil units can be cooled only with a cooling equipment installed in a charger.
