ELECTROMAGNETIC FIELD CONTROLLING SYSTEM AND METHOD FOR VEHICLE WIRELESS CHARGING SYSTEM
First Claim
1. An electromagnetic field controlling system, comprising:
- a magnetic field sensor disposed in or proximate to a vehicle charged using a wireless charging system and configured to detect a magnitude of an electromagnetic field; and
an output controller configured to adjust output power in a power transmission side of the wireless charging system, based on a comparison between a predetermined value for an electromagnetic field and the magnitude of the electromagnetic field detected by the magnetic field sensor.

Abstract
An electromagnetic field controlling system and method are provided. The electromagnetic field controlling system includes a magnetic field sensor that is disposed proximate to or in a vehicle that charges electric power using a wireless charging system and is configured to detect the magnitude of an electromagnetic field. An output controller adjusts output power in a power transmission side of the wireless charging system based on a comparison between a predetermined value for an electromagnetic field and the magnitude of the electromagnetic field detected by the magnetic field sensor. Accordingly, the magnitude of an electromagnetic field output from a vehicle wireless charging system is controlled within a safe range.
