System and method of inductive charging and localization through using multiple primary inductive coils to detect the induced voltage of a secondary inductive coil

An inductive localization and charging system for detecting and charging a device, the system comprising:

• a plurality of primary inductive coils arranged within a dielectric material;
• an input connector coupled to the plurality of primary inductive coils and configured to receive input power;
• a controller coupled to the plurality of primary inductive coils and to the input connector, the controller configured to:
• selectively activate each primary coil of the plurality of primary inductive coils during a dwell time;
• measure a first voltage value for each activated primary coil of the plurality of primary inductive coils during the dwell time;
• determine whether the first voltage value is above a reference threshold voltage;
• set a flag indicating one or more activated primary coils is within operable proximity of a secondary coil in response to the determination that the first voltage value is above the reference threshold voltage;
• adjust the reference threshold voltage to decrease sensitivity in response to the flag indicating that two or more activated primary coils are within proximity of a secondary coil;
• determine that a first primary coil of the plurality of primary inductive coils is within operable proximity of an external secondary coil located in the device;
• and
• control transfer of power between the first primary coil and the secondary coil to charge the device.
