MUMBAI, India, Feb. 13 -- Intellectual Property India has published a patent application (202541125581 A) filed by Saveetha Engineering College, Chennai, Tamil Nadu, on Dec. 12, 2025, for 'self-contained portable solar power system.'
Inventor(s) include R. Umamaheswari.
The application for the patent was published on Feb. 13, under issue no. 07/2026.
According to the abstract released by the Intellectual Property India: "In today's world, rapid advancements m science and technology have made people increasingly dependent on electronic gadgets for their daily activities. This growing reliance has led to a higher demand for electricity, most of which is still generated from non-renewable resources, resulting in resource depletion and environmental strain. Moreover, frequent charging and maintenance of these devices cause significant energy waste and time loss for users. To address these issues, the present invention introduces a lightweight, pOiiable solarpowered device that integrates both charging and energy storage functions within a single compact system. The invention utilizes renewable solar energy to power electronic devices efficiently, eliminating the need for conventional electrical sockets and enabling continuous charging even during outdoor activities such as trekking or hiking. The system employs a microcontroller programmed with an MPPT (Maximum Power Point Tracking) algorithm to achieve maximum energy extraction from sunlight. A bidirectional DC-DC SEPJC converter, combined with supercapacitors and a rechargeable battery, allows for fast charging, efficient power conversion, and reliable energy storage. Intelligent switching ensures that the device operates seamlessly under both sunlight and low-light conditions-providing a sustainable, efficient, and portable power solution unmatched by existing technologies."
