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 generated by a power transmission side of the wireless charging system while the wireless charging system is operating to charge a battery in the vehicle; and
an output controller configured to compare the detected magnitude of the electromagnetic field generated by the power transmission side of the wireless charging system with a predetermined value for an electromagnetic field and adjust output power in the power transmission side of the wireless charging system based on whether the detected magnitude of the electromagnetic field generated by the power transmission side of the wireless charging system is less than the predetermined value for the electromagnetic field,wherein the magnetic field sensor is disposed on a floor of the vehicle.

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.
