Research on lithium battery based on temperature influence

本文研究分析了一种基于Simscape的锂电池建模方法.通过Simscape语言建立二阶RC等效电路模型中各个组件的物理模型,然后在Simulink环境中按照等效电路中各组件的物理连接关系搭建锂离子电池的二阶 RC等效电路模型,模型将考虑温度对电池的影响,模型验证结果表明,该方法所建模型能够准确地反映电池的动静态特性.

This paper studies and analyzes a lithium battery modeling method based on Simscape. The physical model of each component in the first-order RC equivalent circuit model is established by Simscape language, and then the first-order RC equivalent circuit model of the lithium-ion battery is built according to the physical connection relationship of the components in the equivalent circuit in the Simulink environment. The model will be considered. The effect of temperature on the battery, model verification results show that the model built by this method can accurately reflect the dynamic and static characteristics of the battery.
