Randomized trial evaluates thermal response in Lithium-Titanium-Oxide cells, suggesting enhanced modeling approaches for battery safety.

The aim is to develop a simplified thermal model for Lithium-Titanium-Oxide cylindrical cells to improve thermal management and safety.
Developed a thermal model integrating an Equivalent Circuit Model and Bernardi equation under natural convection.
Tested under two dynamic current profiles for short and long discharge cycles up to 1C.
Conducted Computational Fluid Dynamics (CFD) analysis for refined convective boundary conditions and compared heat transfer correlations.
Achieved maximum average surface temperatures of approximately 23.3 °C and 24.0 °C for short and long cycles, respectively.
The simplified model maintained a percentage error within ±5% against experimental data.
Morgan's correlation showed an RMSE of 6.3% for short discharge, while Churchill and Chu's correlation had an RMSE of 5.8% for long discharge tests.
