摘要
文中提出了基于安时法计算混合动力电动牵引车蓄电池已用电量,在求出当前蓄电池荷电状态的基础上,利用根据能量守恒模型计算出的蓄电池SOC进行荷电状态校正,采用80C196KC加上相应的感应器来实现。实验表明,该方法测出的蓄电池荷电状态比较准确,有较高的精度。
The used electric capacity and current state of charge of hybrid electric tractor battery are calculated with Ampere - hour method. An energy conversation model is used to correct the calculated state of charge, which is realized by combined 80C196KC and sensors. Tests show that the measured state of charge by this method is relatively accurate.
