摘　　要：对传统的几种蓄电池单体电池内阻测量方法如密度法、开路电压法和直流放电法的原理和特点进行了分析,指出了这些方法存在的缺陷。提出采用改进的交流测量法对蓄电池内阻进行检测,对交流测量法所获得的数据采用差分面积法进行处理。经实践检验,该方法能够很好地检测蓄电池的状态。The principles and features of several traditional measurement methods such as density, open circuit voltage and DC discharge for internal resistance of single celt battery are analyzed with their disadvantages pointed out. The use of improved AC measuring method is suggested for the detection of battery internal resistance, in which the data acquired by AC measuring method are processed by differential-area method. It is verified in practice that the method is efficient in detecting the condition of battery.
