Abstract
Methods, systems, and devices for an external vehicle charging system. The external vehicle charging system includes a first set of inductive coils. The first set of inductive coils include a first inductive coil and a second inductive coil and are configured to provide an alternating magnetic field to one or more inductive loops of a vehicle. The external vehicle charging system includes a sensor configured to detect a position of the one or more inductive loops and a processor. The processor is configured to determine a first threshold distance between the first inductive coil and the second inductive coil to reduce or eliminate interference. The processor is configured to activate the first inductive coil and the second inductive coil so that the first inductive coil and the second inductive coil align with the one or more inductive loops based on the detected position and the first threshold distance.
