补偿电池充电状态的方法、电池管理系统和混合动力车辆
摘要：
在SOC补偿方法中，检测至少具有两个区域的第一SOC，并计算对应于该第一SOC的第一OCV；利用所测量的组电流和组电压以及内电阻来计算第二OCV，并计算对应于该第二OCV的第二SOC；当第一OCV与第二OCV之差大于第一基准时，利用对应于所述两个区域的至少两个第一补偿值中对应于该第一SOC的第一补偿值来补偿该第一SOC；并当第一OCV与第二OCV之差小于第二基准时，利用对应于所述两个区域的至少两个第二补偿值中对应于该第一SOC的第二补偿值来补偿该第一SOC值。
摘要（英）：

In an SOC compensation method, a first SOC having at least two sections is detected, and a first OCV corresponding to the first SOC is calculated; a second OCV is calculated by using the measured packcurrent and voltage, and an internal resistance, and a second SOC corresponding to the second OCV is calculated; when a difference between the first and second OCVs is greater than a first reference,a first compensation value corresponding to the first SOC among at least two first compensation values corresponding to the two sections is used to compensate the first SOC; and when a difference between the first and second OCVs is less than a second reference, a second compensation value corresponding to the first SOC among at least two second compensation values corresponding to the two sections is used to compensate the first SOC value.
