Base on the predicted initial electric power of an open voltage, a Peukert?Ampere?hour method can calculate the used electric value. Base on the calculation the electric change status of the battery, a dynamic model can be used to adjust the ideal.

• 提出了基于开路电压预测初始电量、Peukert-安时法计算已用电量,在求出当前蓄电池的荷电状态的基础上再用基于一阶动态模型进行校正的思想。
