MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202611107038 A) filed by Institute Of Technology And Management Gida, Gorakhpur; Dr. Nk Singh; Shalini; Prof. Krishna Kumar; and Shyam Chaurasiya on September 05, 2026, for 12 Volt Solar Dc Cooler With Automatic Charging Cut-Off And Variable Speed Control.

Inventors include Dr. Nk Singh; Shalini; Prof. Krishna Kumar; Shyam Chaurasiya; and Muhmmad Faisal.

The application for the patent was published on October 23, 2026, under issue no. 43/2026.

Abstract: A solar-powered direct-current cooler with integrated battery charging and load control is disclosed. A photovoltaic panel supplies DC energy through reverse-current protection, input filtering, an adjustable LM317 charging regulator, and a low-loss Schottky protection stage. A battery-voltage-responsive automatic cut-off circuit including a TL431 reference, an adjustable threshold element, and an IRFZ44N MOSFET controls transfer of charging energy to a rechargeable battery. An auxiliary adapter input may provide charging power when solar energy is insufficient. Stored battery energy is distributed to a water-pump branch and a fan-motor branch. A regulated pump supply and switch selectively operate a compatible DC water pump, while an IRF540 MOSFET and potentiometer vary power delivered to a DC motor and fan. The pump circulates water and the fan produces airflow through the cooler assembly. The integrated architecture enables renewable-energy charging, automatic charge termination, battery-backed operation, water circulation, and adjustable airflow within a low-voltage DC cooling system.
