基于US06复合工况的动力电池SOC估计

SOC Estimation of Power Battery Based on US06 Composite Condition

以48 Ah三元锂离子电池(NCM)为研究对象,通过搭建等效电路模型,利用扩展卡尔曼滤波(EKF)的方法进行SOC估计,探究其在US06复合工况下的SOC精度,并开展讨论。

Taking the 48 ah ternary lithium ion battery(NCM)as the research object,by building an equivalent circuit model and using the extended Kalman filter(EKF)method to estimate the SOC,the SOC accuracy under the us06 compound working condition is explored and discussed.
