MAGNETIC FIELD SHIELDING DEVICE FOR NON-CONTACT ELECTROMAGNETIC INDUCTIVE CHARGING ELECTRIC VEHICLE
摘要
PURPOSE: A magnetic field shielding device for a non-contact electromagnetic inductive charging type electric vehicle is provided to improve current collection efficiency by minimizing the leakage of electromagnetic waves and magnetic field to the outside. CONSTITUTION: A feeding unit is buried into a feeding road. The feeding unit is formed with a ferrite core and a primary coil. A current collection unit is installed at a lower part of a vehicle body of an electric vehicle. A shielding member(10) is installed at a vehicle body frame of the electric vehicle. The shielding member blocks the leakage of electromagnetic waves and magnetic field which are generated between the current collection unit and the feeding road.
