摘要
研究分析了一种基于Simscape的锂电池建模方法。通过Simscape语言建立一阶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一阶RC等效电路模型,模型将考虑温度对电池的影响。模型中各组件的参数辨识将通过混合脉冲功率测试实验(HPPC)以及数值优化方法完成。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 presents an effective method for developing lithium cell simulation model based on Simscape. The physical model of each element in the single RC equivalent circuit is generated by compiling the Simscape language code. The whole cell model is completed through connecting all the element modules in Simulink environment according to the equivalent circuit. The parameters of the cell model are estimated by HPPC test and numerical optimization, and the simulation results suggest that the model created in this method is sufficient to account for all dynamic characteristics of the cell
