摘要： Systems and methods in accordance with particular embodiments provide for alignment of an electric vehicle induction coil with a base system induction coil through a determination of the phase of a base system induction coil current signal. In certain embodiments, an electric vehicle induction coil that receives a transmission signal can be determined to be in greater alignment with a base system induction coil that transmits the transmission signal as the phases of the current signals at the base system induction coil and the electric vehicle induction coil converge. One embodiment includes a method of receiving wireless power, including detecting a transmission signal in a wireless power transmission, the transmission signal comprising periodic variations between a first frequency and a second frequency. The method further includes determining a phase of a base system induction coil signal based on the detected transmission signal.
