MUMBAI, India, March 13 -- Intellectual Property India has published a patent application (202531078043 A) filed by Institute Of Engineering & Management, Kolkata, West Bengal, on Aug. 17, 2025, for 'autonomous solar-powered aerial charging station system (aspars) for on-demand power delivery to fixed iot devices.'
Inventor(s) include Dr. Swati Chowdhuri; and Ankita Ray Chowdhury.
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: "Autonomous Solar-Powered Aerial Charging Station System (ASPARS) for On-Demand Power Delivery to Fixed IoT Devices The present invention relates to an aerial charging system capable of delivering wireless power to fixed IoT devices on-demand. This system comprises a solar-powered Unmanned Aerial Vehicle (UAV) equipped with a wireless power transmission module, which can navigate to the location of IoT devices and charge them wirelessly as required. The UAV is used as a wireless charger that charges the battery-operated IoT-based fixed nodes. The charging stations send signals to IoT based fixed nodes using low-power LoRA signals at a regular interval. Upon receiving the signal from the aerial charging station, the potential battery depleted stationary node sends acknowledgement using low-power LoRA signal, mentioning the real time remaining running capacity. The aerial charger receives the acknowledgement message and estimates the position of the potential IoT target node. The flight towards the IoT node is then initiated. Once the aerial charging station reaches the IoT target node, latching is done to initiate wireless power transmission. In case when the aerial charging station receives multiple charging request, then the legitimate IoT target node is decided based on how much remaining power is left to the node. The present invention introduces an innovative aerial charging system designed to deliver wireless power to fixed IoT devices on demand. This system comprises several key components and operates through a coordinated process involving UAVs, wireless power transmission modules, and LoRA communication technology."
