MUMBAI, India, June 26 -- Intellectual Property India has published a patent application (202641072241 A) filed by Nayas; and Rajalakshmi Engineering College on June 10, 2026, for Automatic Battery Overcharge Cutoff Device.
Inventors include Dr. L. Prasanna Venkatesh; and Dr,m. Prasanna Jeyanthi.
The application for the patent was published on June 19, 2026, under issue no. 25/2026.
Abstract: A battery overcharge cutoff device is disclosed for preventing overcharging of a rechargeable battery and extending battery life. The device is positioned inline between an external power source and an electronic device or its charging interface and includes an input terminal, an output terminal, a switching circuit, and a control unit configured to monitor the state of charge (SoC). When the battery reaches a predetermined upper charge threshold, the control unit automatically interrupts the charging current by opening the switching circuit. The device maintains the disconnected state until the battery charge falls below a predetermined threshold or a manual override signal is received, at which point the switching circuit reconnects the power path to resume charging. In this manner, the device enforces a controlled charge-discharge cycle that improves battery longevity, reduces overcharge stress, and enhances operational safety. The section order and drafting style are consistent with standard patent specification guidance and sample patent formatting resources.
