Abstract

Based on Electric Vehicle (EV) Li-ion battery heat transfer mathematical model, the LiMn₂O₄ battery thermo-physical properties and the parameter identification method are analyzed. Finite Element Method (FEM) model of the battery cell is established and the temperature field simulation agrees with the experiment data well. Research on thermo-physical properties and thermal analysis can be used to improve the Li-ion battery application on EVs.
