Abstract
Disclosed are alignment methods and apparatuses for power transmission/reception coils in an electric vehicle wireless power transfer system. An alignment method may comprise moving a primary coil such that a reference center point of the primary coil sequentially passes through a plurality of measurement points located on the primary coil or located outside the primary coil; measuring physical quantities induced in the primary coil by a power or a magnetic field of a secondary coil magnetically coupled with the primary coil at the reference center point and the plurality of measurement points; and calculating a relative position of the primary coil with respect to the secondary coil based on the measured physical quantities.
