Summary:Technologies for wireless charging of an electric vehicle include moving a first coil toward a second coil based on a sensed distance between the first coil and the second coil. In an embodiment, the first coil is embodied as a power transmission coil that is moved toward the second coil, which is embodied as a power receiving coil located in the electric vehicle. The power transmission coil may be moved vertically from a roadway or other substrate beneath the electric vehicle. In another embodiment, the first coil may be embodied as the power receiving coil located in the electric vehicle that is moved downwardly from the electric vehicle toward the second coil, which is embodied as the power transmission coil. In such embodiments, the power transmission coil may be embodied in the roadway or other substrate beneath the electric vehicle. Additional technologies for controlling the movement and transfer of power of the coils are also disclosed.
