Research on the Temperature Performance of a Lithium-Iron-Phosphate Battery for Electric Vehicle

To improve the cruising range and mobility of EVs, various traction batteries (TBs) have been studied and widely used in China. The operation of EVs is difficult because of the reduction in the capacity resulting from the low temperature. A computer model of an electric vehicle power battery is proposed in this paper to study the effect of temperature on battery performance parameters. The variation of EV battery parameters (voltage, current, capacity) with temperature will be discussed, The change of EV battery parameters (voltage, current, capacity) with temperature will be discussed. Experiments at different temperatures have been constructed to verify the accuracy of the model.
