Electric vehicle rapid wireless charging system based on graphene

Abstract

The invention discloses an electric vehicle rapid wireless charging system based on graphene. By using a cable made of graphene to replace a copper wire to coil an iron core, thus the resistance valueis reduced, current is increased, and quality factor is promoted. Under the condition of improving high permeability and keeping unchanged magnetic field intensity, the magnetic induction intensity degree is determined upon coercive force with small magnetic conductivity and rest magnetic induction intensity; smaller material indicates strong magnetization and demagnetization abilities; the hysteresis loop is narrower while the loss in an alternating magnetic field is smaller; the high electrical resistivity is improved, the magnetic core worked in the high-frequency alternating magnetic field has current wetting loss, high electrical resistivity can reduce the current wetting loss; saturated magnetic induction intensity is improved, thus the magnetic core area and the device volume are lessened. Through fusion of the high energy storage graphene material and wireless charging, a traditional research and development barrier is broken through, thus the electric vehicle rapid wireless charging system provides a new method for the use and the development of the wireless electric vehicle.
