## New definition method of state of charge for batteries in HEV

• 摘要: 提出一种新的描述电池荷电状态的定义方法,主要针对MH/Ni动力电池,该电池通常意义下的额定容量为8 A·h,并应用在一种混合动力电动车中.混合动力电动车中动力电池的运行环境非常严酷,充放电倍率高,动态转换频繁.通常的电池荷电状态定义方法适合于稳定负载的情况下,在动态负载的情况下就会出现不适应性.原因是不能同时描述电池的静态和动态荷电状态.新定义方法提出静态荷电状态SSOC(Static State of Charge)和动态荷电状态DSOC(Dynamic State of Charge)的概念.静态荷电状态SSOC描述电池内部稳态的荷电量; 动态荷电状态DSOC描述电池充电或放电时,电池内部电荷的饱和程度.对上述定义的电化学原理进行了分析,并提出了初步的计算方法.
