MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202641036954 A) filed by Sri Venkateswara College Of Engineering & Technology, Chittoor, Andhra Pradesh, on March 26, for 'phase stabilized thermoelectric movable exhaust power generator for automotive systems.'
Inventor(s) include Dr. A. Mahamani; M. Mythreyan; Dr S. Senthil; Dr. P. Narasimha Reddy; Dr. Mohan Babu; Dr A. R. Babu; S. Ramesh; Dr. T Somasoundaram; M Balasubramanyam; K. S. Vijay Kumar; L. Madhi Madhan; and T Srilekha.
The application for the patent was published on May 29, under issue no. 22/2026.
According to the abstract released by the Intellectual Property India: "The proposed device is designed to use waste heat from a vehicle exhaust and convert it into useful electrical energy. Instead of letting this heat escape into the air, the device uses a movable thermoelectric generator (6) placed inside the exhaust pipe to absorb heat directly from the exhaust gases. The device moves within the exhaust, with a microcontroller (3) guiding it towards and away from hotter regions to improve heat absorption and generate electricity more efficiently. It is supported by a movable structure that allows it to adjust its position based on changes in exhaust temperature.-When-the engine operates at higher load and the exhaust temperature rises, the device moves towards or away from higher temperature areas to give efficient desired electrical output. The thermoelectric module has a hot side connected to a heat absorbing surface and a cold side connected to a phase change material (PCM) (2). The PCM (2) helps keep the cold side temperature stable, which improves energy conversion and reduces damage caused by temperature fluctuations. The device is designed to continuously adapt to changing exhaust conditions, maintaining reliable electricity generation. An intelligent power conditioning unit, including a low voltage start up circuit, DC- DC boost converter, and maximum power point tracking (MPPT) controller, ensures efficient energy harvesting under different driving conditions. The generated electricity is stored in a rechargeable battery and used to electronic devices in the vehicle, reducing the load on the main battery and improving overall energy efficiency."
