Under number US 9778653 B1 , Amazon filed a patent in June 2014 describing the charging of an electric vehicle by drones. To this end, the vehicle would be equipped with a kind of docking station on its roof, which the flying device could attach itself to even on a moving vehicle. Prerequisite is that the route is relatively straight and has no obstacles such as bridges, tunnels or trees that might impair contact. The patent was approved in September.
Previously, Amazon had sought a patent for the mobile charging of unmanned aerial vehicles . The concept envisages setting up charging stations in the form of standard containers. The drone would touch down on the inside through a hole in the roof, receive new batteries and spare parts, if required, and then start up again. According to Amazon’s vision, such service containers could be set up at locations where there is a particularly high demand for goods for a short period. The containers could then be moved to another location by train, ship or truck.
