MUMBAI, India, Feb. 6 -- Intellectual Property India has published a patent application (202541122629 A) filed by Easwari Engineering College, Chennai, Tamil Nadu, on Dec. 5, 2025, for 'elephant ear-mimetic radial channel cooling architecture using pla+ for passive electric vehicle battery heat management.'
Inventor(s) include Dr. Thavasilinga M Kannan; Pavan Raj Sridharan; Sethu Alagesh Kannan; Chrish Franklin Hosana; Sudharshan NV; and Tharunesh Nagarajan.
The application for the patent was published on Feb. 6, under issue no. 06/2026.
According to the abstract released by the Intellectual Property India: "This work unveils a non-active temperature management mechanism for lithium-ion battery packs in electric vehicles which consists of a biomimetic cooling shell resembling the structure of IO elephant ears that can disperse heat and is constructed out of PLA+ using 3D printing. The whole system is made up of a cooling shell imitating the structure of elephant ears placed on the sides of a battery casing. This shell consists ofa curved radiative membrane, an internal porous lattice layer and a network of hollow radial channels that encourage buoyancy-driven natural convection, all . integrated into one. The heat coming from the cylindrical cells in the battery pack is transported to X - 15 l^he lattice core, uniformly spreading over the cooling shell, and then getting rid of through surface /radiation and passive airflow through the radial channels, thus allowing fully energy-free operation 'Avithout fans, pumps, or active components of cooling. The monolithic construction of PLA+ 'w hich was created by melted deposition modelling enables the combining of complicated geometries like the asymmetric curvature, triply periodic minimal surface lattices, and branching 20 air conduits in one structure. The invention presents a cost-effective, lightweight, and eco-friendly method of thermal management that can help to lessen temperature differences, prevent the formation of hotspots and keep the temperature at battery modules in EVs more stable."
