Selecting a configuration of coils in response to a multi-coil wireless charging system initiating charging
First Claim
1. A system for selecting a configuration of coils in response to a multi-coil wireless charging system initiating charging, comprising:
- a data store comprising a computer readable medium storing a program of instructions for the selecting of the configuration;
a processor that executes the program of instructions;
a ping generator to measure a reference coil peak voltage and a coil peak voltage for each of the coils of the multi-coil wireless charging system;
an object detector to detect that an object is placed on a surface associated with the wireless charging system, by cycling via the ping generator, to measure each coil of the multi-coil wireless charging system individually and storing an individual reading of the coil peak voltage for each coil, and correlating a position of the object based on the individual reading of the coil peak voltage,a charge detector to detect that the object is chargeable by comparing the stored coil peak voltage and the reference coil peak voltage, andin response to the object being chargeable, a switch transmitter determines which of the coils of the multi-coil wireless charging system to connect to a power source, the determination being based on a determined position based on the individual reading of the coil peak voltage for each coil.
