Abstract: A linking device to electrically link an electric vehicle to a power line extending along a path, may include an unmanned aerial vehicle (UAV) comprising: a controller to operate flight controls of the UAV; an electric current collector for placing in contact with and collecting an electric current from the power line; and a power cable to transfer the electric current, the cable having a distal end and a proximal end, the distal end of the cable being electrically linked to the electric current collector and the proximal end being electrically linked to an electric battery of the electric vehicle or to an electric motor of the electric vehicle. The controller is configured to operate the flight controls to cause the UAV to ascend or descend so as to facilitate contact between the electric current collector and the power line and to maintain that contact while being towed by the electric vehicle, when the electric vehicle is traveling along the path.
