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, and in 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.
