基于新电源模型的动力锂电池荷电状态估计研究
|
摘要
锂电池的等效电路模型与电池内部电化学状态不一致,对电池状态的估计不可避免地存在很大误差.基于算法的补偿不能从根本上解决问题.故提出一种基于电池内部电化学反应和电池的外部特性关系的电源模型.经实验测试,该电池模型与现有的电池模型相比精度较高.
The equivalent circuit model of lithium battery is not consistent with the internal electrochemical state of the battery.The estimation of the state of the battery has great errors inevitably,and the compensation based on the algorithm can not solve the problem completedly,A new equivalent circuit model is proposed.This model is based on the relationship between the electrochemical reaction inside the battery and the external characteristics of the battery.The model was verified by experimental test.Its accuracy is higher than the existing battery model.
