MUMBAI, India, March 13 -- Intellectual Property India has published a patent application (202521073825 A) filed by Ramdeobaba University; Shri Ramdeobaba College Of Engineering And Management; Saonerkar, Ameya; Huchche, Vijaya; and Bhandarkar, Tejas Rajkumar, Nagpur, Maharashtra, on Aug. 3, 2025, for 'a system for in-flight electromagnetic inductive charging of unmanned aerial vehicles via high-voltage transmission lines.'
Inventor(s) include Saonerkar, Ameya; Huchche, Vijaya; and Bhandarkar, Tejas Rajkumar.
The application for the patent was published on March 13, under issue no. 11/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a system for in-flight electromagnetic inductive charging of unmanned aerial vehicles via high-voltage transmission lines. The system comprises: an inductive coil (101), a full-wave bridge rectifier (102), a maximum power point tracking (MPPT) controller (103), a surge arrestor (104), an optional propulsion load (105), a battery management system (BMS) (106), a power splitter (107), a safety circuit (108), a thermal sensor (109), and a rechargeable battery bank (110). The coil (101), embedded within the UAV's wing or fuselage, harvests alternating magnetic fields from HVTLs operating at 33-765 kV. EMF sensors maintain an optimal UAV distance of 0.5-1.0 m from the conductor. Induced voltage (~15 V) and current (~1 A) are stabilized and stored onboard. The system supports safe, contactless charging without altering existing infrastructure and enables extended missions for surveillance, inspection, logistics, and emergency operations by converting HVTL corridors into aerial charging zones."
