  • Wireless charging magnetic structure
    Patent number: 10131236
    Abstract: In at least one embodiment, an inductive charging coil assembly for a vehicle comprising a first base plate and a second base plate is disclosed. The first base plate includes at least one first coil for transmitting magnetic flux. The second base plate includes at least one second coil having a top side and a bottom side to receive the magnetic flux for charging a vehicle. The at least one second coil defines a window to position at least one ferrite on the top side and on the bottom side of the at least one second coil. The at least one ferrite is arranged to guide the magnetic flux from the bottom side of the at least one second side to the top side of the at least one second side and back to the bottom side of the at least one second side.
    Type: Grant
