A connection system and connection method for easily charging an electric automotive vehicle are provided. A secondary coil 20 connected with a battery 21 is provided at the bottom of a body of an electric automotive vehicle E. On the other hand, a recess A is formed in the ground of a parking lot, and a coil moving device 30 for movably supporting a primary coil 10 is installed in the recess A. Three magnetic sensors 50 are provided on a body 40 of the coil moving device 30. Further, power supply circuits 13a to 13e provided in an external power supply equipment 11 at the back of the parking lot and a main controller 12 supply power to the primary coil 10, magnetic sensors 50 and coil moving device 30 and control them. In order to charge the battery 21, the vehicle E is parked, straddling the recess A, and the secondary coil 20 is excited. Then, the magnetic sensors 50 detect the position of the secondary coil 20, and the main controller 12 drives the coil moving device 30 to guide the primary coil 10 to a position where both coils 10, 20 are to be electromagnetically coupled.
