Preliminary Study of a Distributed Thermal Model for a LFP Battery in COMSOL Inc. Multiphysics(MP) Software

Abstract

In order to better understand the thermal behavior of high capacities and large power lithium-ion batteries for electric vehicle application, a distributed thermal model of a LFP battery is proposed. The model includes a 3-D electrode plate pair model based on porous-electrode theory and a 3-D battery model solving the temperature distribution of the battery. These models are coupled through heat generation rate and transient temperature during discharging process.
