A method of determining alignment of an inductive power coupler of an electric vehicle relative to an inductive power transmit element includes: receiving, at the electric vehicle, a first wireless signal and a second wireless signal; analyzing the first wireless signal and the second wireless signal to determine an alignment value, the alignment value being a magnitude of the first wireless signal relative to a magnitude of the second wireless signal or being a difference between a time of arrival of the first wireless signal and a time of arrival of the second wireless signal; and determining, based on the alignment value, an indication of a lateral offset of the inductive power coupler of the electric vehicle relative to the inductive power transmit element.
