摘要:
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.
