Abstract
Efficient thermal management of lithium iron phosphate (LFP) batteries is essential to enhance safety and performance in electric vehicle and stationary storage applications. This study presents a detailed CFD-based thermal simulation of a 23-cell battery module during charging and discharging cycles using Cradle SCStream. Heat generation is analytically estimated based on internal resistance, and simulations capture thermal gradients, heat flow, and temperature evolution over time. Simulation results reveal critical insights into the thermal performance of LFP cells under different operating currents.
