1. An external vehicle charging system, comprising:

  • a first inductive coil configured to move in three-dimensions to align with a first inductive loop of a vehicle and to provide a magnetic field to the first inductive loop of the vehicle;

    a camera configured to capture an image of an underside of the vehicle; and

    a processor coupled to the first inductive coil and the camera, the processor being configured to;

    obtain user input that includes a configuration setting that indicates to activate the first inductive coil from among a first plurality of inductive coils,identify the first inductive loop in the image of the underside of the vehicle,determine a position of the first inductive loop of the vehicle based on the image of the underside of the vehicle,determine a distance that the first inductive coil is offset from the first inductive loop of the vehicle based on the position of the first inductive loop of the vehicle and a location of the first inductive coil,determine whether the first inductive coil is aligned with the first inductive loop of the vehicle based on the distance, andactivate the first inductive coil when the first inductive coil is aligned with the first inductive loop of the vehicle and the configuration setting that indicates to activate the first inductive coil is obtained.
