针对电池SOC与SOH估计结果相互影响,单独估计准确度不高的问题,该文提出了一种基于等效电路模型和数据驱动模型融合的SOC和SOH联合估计方法。通过构建考虑老化和SOC的电池二阶RC等效电路模型,采用带遗忘因子的递推最小...展开更多 针对电池SOC与SOH估计结果相互影响,单独估计准确度不高的问题,该文提出了一种基于等效电路模型和数据驱动模型融合的SOC和SOH联合估计方法。通过构建考虑老化和SOC的电池二阶RC等效电路模型,采用带遗忘因子的递推最小二乘法,在不同SOC和SOH的情况下,对电池的参数进行在线辨识,实现电池参数在线辨识与电池SOC和SOH估计的耦合。以锂离子电池自SOC=20%到恒流充电阶段结...

The accuracy of state of charge(SOC)can be significantly affected by battery aging,leading to misguidance in the calibration of state of health(SOH).Existing studies often estimate SOC and SOH separately,neglecting their close relationship and resulting in reduced estim...MORE The accuracy of state of charge(SOC)can be significantly affected by battery aging,leading to misguidance in the calibration of state of health(SOH).Existing studies often estimate SOC and SOH separately,neglecting their close relationship and resulting in reduced estimation accuracy.This paper proposes a joint estimatio...
