A method comprising: detecting that a wireless charging-capable vehicle is in a charging position proximate a primary coil of a wireless charging system that is operable to wirelessly charge the vehicle via a secondary coil installed in the vehicle, wherein the primary coil includes 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 each including a switching element that routes electric current through at least a portion of one or more of the top coil and the bottom coil; setting the switching elements such that current flowing through the primary coil produces an optimal angle of magnetic flux for wirelessly charging the vehicle given a position of the primary coil with respect to a position of the secondary coil; causing electric current to flow through the primary coil according to the set switching elements to wirelessly charge the vehicle; cycling through a plurality of current flow configurations in the primary coil by adjusting states of the switching elements; receiving charging efficiency data from the vehicle during the cycling through of the plurality of current flow configurations; determining which current flow configuration of the plurality of current flow configurations produces the optimal angle of magnetic flux for wirelessly charging the vehicle based on the charging efficiency data; and setting the switching elements according to the determined current flow configuration, wherein the optimal angle of magnetic flux for wirelessly charging the vehicle is an angle offset from a vertical axis extending upwardly from the primary coil when the vehicle is positioned such that the secondary coil is misaligned with the primary coil. detecting that a wireless charging-capable vehicle is in a charging position proximate a primary coil of a wireless charging system that is operable to wirelessly charge the vehicle via a secondary coil installed in the vehicle, wherein the primary coil includes 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 each including a switching element that routes electric current through at least a portion of one or more of the top coil and the bottom coil; setting the switching elements such that current flowing through the primary coil produces an optimal angle of magnetic flux for wirelessly charging the vehicle given a position of the primary coil with respect to a position of the secondary coil; causing electric current to flow through the primary coil according to the set switching elements to wirelessly charge the vehicle; cycling through a plurality of current flow configurations in the primary coil by adjusting states of the switching elements; receiving charging efficiency data from the vehicle during the cycling through of the plurality of current flow configurations; determining which current flow configuration of the plurality of current flow configurations produces the optimal angle of magnetic flux for wirelessly charging the vehicle based on the charging efficiency data; and setting the switching elements according to the determined current flow configuration, wherein the optimal angle of magnetic flux for wirelessly charging the vehicle is an angle offset from a vertical axis extending upwardly from the primary coil when the vehicle is positioned such that the secondary coil is misaligned with the primary coil.
