摘要
基于锂电池Thevenin等效电路模型建立了无迹卡尔曼滤波锂电池SOC估算模型,通过实验方法确定了锂电池Thevenin模型参数,并对锂电池放电过程中SOC实时估算。通过与理论值SOC对比,该模型具有较高估算精度,整体误差小于0.04%,满足锂电池SOC估算要求。
Based on Thevenin equivalent circuit model,the SOC estimation model of the lithium battery with unscented Kalman filter is established in this paper.The parameters of lithium battery model are determined by experiments,and the SOC of lithium battery is estimated in real time.Compared with the theoretical value of SOC,the model has a high estimation accuracy,the error is less than 0.04%,which meets the SOC estimation requirements of lithium battery.
