The invention discloses an SOP correction method, a battery management system and a computer readable storage medium, and the method comprises the steps: obtaining a current first SOP value; wherein the SOP value represents the power state of the battery; when the current discharge current is smaller than the reference discharge current, the minimum voltage value of the current single battery is smaller than the minimum voltage value of the reference single battery, and the voltage difference value of the current single battery is smaller than the voltage difference value of the reference single battery, the first SOP value is corrected to be a set second SOP value, and the second SOP value is smaller than the first SOP value; wherein the current single battery voltage difference value is the difference value between the current single battery voltage maximum value and the current single battery voltage minimum value, and the reference single battery voltage difference value is the difference value between the reference single battery voltage maximum value and the reference single battery voltage minimum value; the reference discharge current, the reference cell voltage maximum value, and the reference cell voltage minimum value are determined by a first SOP value. Through the above mode, adaptive calibration of the SOP can be realized.
本申请公开了一种SOP修正方法、电池管理系统以及计算机可读存储介质,其中,该方法包括:获取当前的第一SOP值;其中,SOP值表示电池功率状态;在当前放电电流小于参考放电电流、且当前单体电池电压最小值小于参考单体电池电压最小值、且当前单体电池电压差值小于参考单体电池电压差值时,将第一SOP值修正为设定的第二SOP值,第二SOP值小于第一SOP值;其中,当前单体电池电压差值为当前单体电池电压最大值和当前单体电池电压最小值的差值,参考单体电池电压差值为参考单体电池电压最大值和参考单体电池电压最小值的差值,参考放电电流、参考单体电池电压最大值和参考单体电池电压最小值由第一SOP值确定。通过上述方式,能够实现SOP的自适应校准。
