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.

Abstract
A charging facility includes a primary coil, magnets arranged relative to the primary coil in a pattern such that fields generated by the magnets can be used to position a vehicle relative to the primary coil, and a controller. Some of the magnets have a predefined polarity signature encoding data regarding an identify of the primary coil. The controller is programmed to receive information from or provide information to the vehicle about the predefined polarity signature.
