MUMBAI, India, Jan. 23 -- Intellectual Property India has published a patent application (202631003328 A) filed by National Institute Of Technology, Rourkela, Orissa, on Jan. 12, for 'single converter fed hybrid energy storage unit with transient current mitigation for efficient motoring and regenerative braking in low-voltage ev drivetrain.'
Inventor(s) include Dr. Monalisa Pattnaik; Dr. Pradyumna Kumar Behera; and Mr. Karan Gupta.
The application for the patent was published on Jan. 23, under issue no. 04/2026.
According to the abstract released by the Intellectual Property India: "The invention provides a Single Converter fed Hybrid Energy Storage Unit (HESU) for low-voltage electric vehicle (EV) drivetrains, specifically targeting electric scooters and e-rickshaws. The HESU integrates an electrochemical battery and a supercapacitor via a single bidirectional DC-DC converter, significantly reducing component count and cost compared to multi-converter architectures. A series inductance is integrated into the battery path to mitigate transient current stress by providing high impedance against rapid power fluctuations. During acceleration and regenerative braking, high-frequency current components are naturally diverted to the supercapacitor, while the battery supplies steady-state energy. This hardware-level protection enhances battery cycle life and thermal reliability without the need for complex active control or additional sensing. Experimental validation confirms precise DC bus regulation and efficient energy utilization during frequent start-stop operations."
