Wireless charging system for electric vehicle with adjustable flux angle

A wireless charging system comprising:

• a primary coil that is operable to wirelessly charge a moving, wireless charging-capable vehicle which travels over the primary coil,
• wherein the primary coil charges the vehicle via a secondary coil installed in the vehicle, the primary coil including a top coil and a bottom coil that are substantially parallel to one another, the top coil and the bottom coil coupled to one another via a plurality of cross-coil junction units that permit electric current to pass from one of the top coil and the bottom coil to the other of the top coil and the bottom coil;
• and
• a wireless charging controller configured to:
• detect a position of the vehicle which travels over the primary coil,
• control 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, control 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,
• wherein the first angle of magnetic flux is different than the second angle of magnetic flux.
