An implementation provides an apparatus for determining an alignment of a wireless power coupler of a vehicle with a wireless power transmitter. The apparatus comprises a sensing circuit configured to measure a current in a plurality of separate conductors of the wireless power coupler. The apparatus comprises a controller configured to determine information related to an alignment of the wireless power coupler with the wireless power transmitter based at least in part on the measured current in the plurality of separate conductors. The controller is configured to determine the information related to the alignment of the wireless power coupler with the wireless charging power transmitter based on a difference between the measured current in the plurality of separate conductors. The information comprises a direction and distance of offset between the wireless power coupler and the wireless power transmitter. The measured current is a short circuit current.
