| 摘 要： | 分析比较几种判断铅酸电池放电终止状态的方法，指出这些以恒流放电特性为基础的放电终止状态判断标准不适于在变电流放电状态下工作的混合动力电动汽车用电池；U-C曲线斜率法考虑了变电流放电因素，适用于混合动力电动汽车电池管理系统对电池终止放电状态进行实时判断。

| Abstract: | In this paper, several methods to judge the final state of lead acid battery discharge are analyzed and compared. And it is pointed out that the standard under constant current is not suitable for hybrid EV batteries under variational current discharge conditions. The U-C rate of curves method takes the factor of variational current discharge into account, and its data sampling and calculation are simple. This method is suitable for real-time judgement of final state of hybrid EV battery discharge, |
