APPARATUS, METHOD AND SYSTEM FOR WIRELESS CHARGING FOR VEHICLE USING RESONANCE MAGNETIC INDUCTION

摘要

PURPOSE: An apparatus, a method and a system for wireless charging for a vehicle based on resonance magnetic induction are provided to improve charging efficiency. CONSTITUTION: A multi axial coil unit(110,120) communicates with an external charger through a magnetic field. The multi axial coil unit uses a resonance channel and transmits charging power to the external charger. A magnetic field communication modem unit(130) converts a magnetic signal into a packet data form. The magnetic signal is received through a magnetic communication protocol. A band selection unit(150) selects a coil to which charging power is transmitted. A controller(140) controls the band selection unit.
