摘要
随着氢镍蓄电池在日常生活中的普及应用,针对较难判断氢镍蓄电池劣化程度这一问题,通过分析电池老化实验的实验数据,找出一定条件下电池劣化程度与充满电的电池外部可测量参数之间的关系,建立了表征电池劣化程度与电池外部可测量参数关系的四阶多项式数学模型,从而得到能够快速判断氢镍蓄电池劣化程度的检测方法。经实验验证,这种方法是有效的。
With the popularization and application of MH-Ni rechargeable battery in daily life, it＇s difficult to judge the degradation degree of batteries. After battery aging experiment, through the analysis of experimental data, it is found out that the relationship between the degradation degree of battery on certain conditions and the external measurable parameters of the fully charged battery. The fourth-order polynomial mathematical model to characterize this relationship is established. The detection method which can judge the degradation degree of MH-Ni rechargeable battery is obtained quickly. Through the experiment, this method proved to be effective.
