A method includes: detecting a position of a moving, wireless charging-capable vehicle which travels over a primary coil of a wireless charging system operable to wirelessly charge the vehicle via a secondary coil installed in the vehicle; controlling the plurality of cross-coil junction units such that electric current flows through one or both of the top coil and the bottom coil in a manner which produces a first angle of magnetic flux for optimally wirelessly charging the vehicle given a position of the primary coil in relation to the detected position of the vehicle; and when a switching time occurs, controlling the plurality of cross-coil junction units to change the flow of electric current through one or both of the top coil and the bottom coil in a manner which produces a second angle of magnetic flux for optimally wirelessly charging the vehicle given the position of the primary coil in relation to an updated position of the vehicle as the vehicle traverses the primary coil.
