Abstract: An example embodiment of the invention is a method and device for detecting foreign objects (FO) near the primary coil of an induction charger used in charging electric vehicle batteries. Individual sensors of a sensor array are configured to output a sensing signal in response to magnetically coupling the high frequency alternating magnetic field produced by the primary coil. A disable signal line is configured to disable the power source when a controller determines from scanned sensor signals, that a FO is present. An alarm can be activated by the microprocessor to alert the user to the presence of a FO on or near the primary coil. In this manner, damage can be avoided that could otherwise be caused from the presence of a FO near the primary coil. Moreover, a more efficient charging operation can be achieved by avoiding dissipating energy by heating a FO.

Abstract: The invention detects foreign objects FO near a primary coil 100 of an induction charger. A sensors 111 of a sensor array 110 output sensing signals in response to magnetically coupling the alternating magnetic field 103 produced by the primary coil. A controller 165 connected to each sensor 111 scans the sensing signals and determines whether there is a foreign object perturbing the magnetic field 103 near a sensor. The magnetic field has a spatial distribution that varies by location across the primary coil area. Each sensor has a magnetic field sensing sensitivity that is inversely proportional to the magnetic intensity of the magnetic field produced by the primary coil at a location of the sensor, to reduce the collective dynamic range of the signals, thereby contributing to maintaining a high accuracy in signal sampling. A reference sensor coil 155 compensates for magnetic field drift of the primary coil.
