MAGNETIC FIELD SHIELDING MODULE FOR ELECTRIC VEHICLE, AND WIRELESS POWER TRANSMISSION MODULE INCLUDING SAME FOR ELECTRIC VEHICLE
Abstract:
A magnetic field shielding module for an electric vehicle is provided. A magnetic field shielding module for an electric vehicle according to an embodiment of the present invention may comprise: a main shielding layer including a plurality of unit blocks made of a ferrite material to shield a magnetic field generated from a planar coil in which a conductive member is wound multiple times, the main shielding layer being formed in a plate shape having a predetermined area by the plurality of unit blocks arranged adjacent to each other; and an auxiliary shielding layer made of a magnetic material containing a metal component to supplement the main shielding layer, disposed on one surface of the main shielding layer, and including a penetrating portion formed in a shape corresponding to that of the planar coil.
