Magnetic coupling device for charging an electric vehicle
First Claim
1. A magnetic coupling device for charging an electric vehicle comprising:
- a primary unit having a primary core and a primary coil wound on said primary core; and
a secondary unit having a secondary core and a secondary coil wound on said secondary core, said secondary unit disposed on the electric vehicle and coupled with said primary unit, so that said primary and secondary cores constitute a closed loop-like magnetic circuit;
each of said primary and secondary cores having a junction face which contacts with each other under the coupling, said primary unit coupled with said secondary unit in an attaching direction of said primary unit along an attaching axis at least parts of the primary and secondary coils being laterally arranged with respect to the attaching direction of the primary unit;
wherein said junction faces of said primary and secondary cores have a mutually opposing relationship in which said junction faces intersect with the attaching axis.
