1. A charging facility comprising:

  • a primary coil;

    electromagnets arranged relative to the primary coil in a pattern, wherein fields generated by the electromagnets can be used to position a secondary coil of a vehicle relative to the primary coil, and the electromagnets have a predefined polarity signature encoding data regarding an identity of the primary coil; and

    a controller programmed to alter a polarity of the electromagnets to further encode data in the electromagnets, and to receive information from the vehicle about the identity of the primary coil.
