MUMBAI, India, April 10 -- Intellectual Property India has published a patent application (202411071256 A) filed by Indian Institute Of Technology, New Delhi, on Sept. 20, 2024, for 'a dynamic undervoltage protection method for high c-rate discharge li-ion batteries.'
Inventor(s) include Panigrahi, Bijaya Ketan; and Tripathi, Prabhat Ranjan.
The application for the patent was published on April 10, under issue no. 15/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a dynamic undervoltage protection method for high C-rate discharge Li-ion batteries, aimed at enhancing battery management systems. Traditional battery protection systems often rely on fixed thresholds for voltage, current, and temperature, which can lead to premature cutoffs and underutilization of battery capacity, especially in high C-rate discharge applications. This invention introduces a sophisticated algorithm that dynamically adjusts undervoltage protection triggers by continuously monitoring cell voltage, current, temperature, and state-of-charge (SoC). The protection mechanism is activated only when an undervoltage event is accompanied by a breach in any other parameter threshold, ensuring full utilization of the battery while preventing damage. This method is particularly beneficial for applications such as power tools, electric vehicles, and unmanned aerial vehicles (UAVs), where high C-rate discharges are common. The proposed algorithm can be integrated into existing battery protection systems, offering a plug-and-play solution that extends battery life and reliability."
