The internal resistance of polymer lithium battery was tested and the fitting equation of internal resistance against temperature and capacity change was obtained. Based on the equation, the mathematical model to simulate the situation of the single battery temperature rising at a constant resistance and variable resistance was established. The results show that the resistance has a significant impact on battery temperature rising under the decided conditions. The battery temperature rising will have a larger calculation error at a constant resistance.
