软包装锂离子动力电池生热速率测算方法研究

Study on measuring and calculating method for heat generation rate of soft-packed lithium-ion power battery

从锂离子动力电池的生热原理入手,参照Bernardi电池生热模型采集相关实验数据,并对实验数据进行处理,研究电池的温升特性,测算出锂电池的等效热容值和生热速率公式,为使用数字化模型研究单体电池的温度场分布特性提供了参数依据。

Based on the heat-generating principle of lithium-ion battery, and according to the Bernardi heatgenerating model, the experimental data were collected and were processed to find the temperature rise characteristics, including the measurement of equivalent heat capacity and the heat-generating rate formula, which provided the basis for using digital model to study the temperature distribution characteristics of single battery.
