| Abstract: | A three-dimensional mathematical model is built to describe the thermal characteristic of lithium battery. Lithium battery which has very complicated internal structure is considered as a whole to get its thermo-physical parameters. A method of piecewise linear interpolation is used to study the variation of specific heat capacity and thermal conductivity as SOC (state of charge) of battery changes. The three-dimensional temperature field of a single lithium/sulfur dioxide battery is simulated using commercial CFD software FLUENT, then the factors affecting the temperature distribution of the battery including variation of thermo-physical parameters, discharge current and cooling environment are analyzed. |
