A magnetic coupling device for charging an electric vehicle includes: a primary unit having a primary core and a primary coil wound on the primary core; and a secondary unit having a secondary core and a secondary coil wound on the secondary core, the secondary unit disposed on the electric vehicle and coupled with the primary unit, so that the primary and secondary cores constitute a closed loop-like magnetic circuit; each of the primary and secondary cores having a junction face which contacts with each other under the coupling, wherein the junction faces of the primary and secondary cores have a mutually opposing relationship in which the junction faces intersect with an attaching direction of the primary unit.

A C-shaped fixed core is provided at a power receiving portion, and a secondary coil is wound on a vertical portion of the fixed core. A moving core is vertically movable in sliding contact with distal end surfaces of horizontal portions of the fixed core. A primary coil, having an air core portion, is provided at a charging coupler. When the charging coupler is attached to the power receiving portion, the moving core is moved downward to extend through the air core portion of the primary coil, and opposite end portions of the moving core are contacted respectively with the horizontal portions of the fixed core. As a result, a magnetic circuit is formed between the primary and secondary coils. The charging coupler is lightweight since it does not have a core.

A slidable element is provided for easy positioning in a guide slot when a handle is withdrawn. A handle 40 is inclinably provided on a mount body 35 bearing a movable electrode 31 by a support shaft 45. The support shaft 45 is loosely movable with respect to the mount body 35 by being fixed to the handle 40 and being inserted through oblong holes 42 formed in bearing portions 41 of the mount body 35. In order to withdraw the handle 40, it is necessary to position slidable projections 70 at the bottom ends of linear portions 75 of guide slots 74 while the handle 40 is pulled up. Since the support shaft 45 is movable upward within the oblong holes 42, the handle 40 can singly be pulled up while the movable electrode 31 is still engaged with the fixed electrodes 11a, 11b. During this time, the slidable projections 70 can be positioned and passed through the linear portions 75 of the guide slots 74 with a small force.

A compact breaker device includes a pair of fixed electrodes 11a, 11b are placed upright at one side of the casing 1, and a fuse 12 is accommodated at the other side thereof. A movable electrode 31 including a pair of fittable terminals 32a, 32b connected with each other is mounted on a mount body 35. By engaging and disengaging the fittable terminals 32a, 32b with and from the fixed electrodes 11a, 11b through the ceiling wall of the casing 1, a breaker switch for connect and disconnect the fixed electrodes 11a, 11b is formed. The fuse 12 is connected in series with the breaker switch. A handle 40 is inclinably mounted on the upper surface of the mount body 35. The handle 40 is firmly held in a standing position and a resting position by a spring member 47 provided between it and the mount body 35. The handle 40 is inclined to the resting position when the breaker device is used, while being held upright when the breaker switch is turned on and off.

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.

An electric vehicle charging connector used for charging a power battery of an electric vehicle includes connector holder and a display section mounted in an upper portion of the connector holder. The display section includes red and green light-emitting diodes and a seven-segment two-digit numeric display including light-emitting diodes. The red light-emitting diode is turned on while the power battery is being charged. The green light-emitting diode is turned on instead of the red light-emitting diode when charging has been completed. Either the time elapsed after the charging operation has been initiated or the remaining capacity of the power battery is displayed by the numeric display.
