1. An inductive charging coil assembly for a vehicle comprising:
- a first base plate including at least one first coil thereon for receiving magnetic flux to charge a vehicle battery;
a second base plate including at least one second coil having a top surface thereof that forms an elevated portion to focus the magnetic flux to the at least one first coil; and
a first plurality of ferrites, each ferrite being co-planar and extending in a different radial direction from a first center point about the at least one second coil for guiding the magnetic flux from the elevated portion to the at least one first coil.
