摘要 影响VRLA铅蓄电池质量和使用寿命的因素有多种,自诞生以来,一直采用检测和监视其电压的方法来判定电池的质量和使用寿命.经过各种因素的分析,认为VRLA铅蓄电池的内阻是一个判定质量和使用寿命的敏感参数.在实际运行中也发现,蓄电池内阻发生变化,必然导致其放电能力的下降.文中对现有不同内阻测试方法进行了分析,对现有电池模型提出了质疑. We all know that there are a variety of factors which affect the quality and life of VRLA Lead-acid- battery. Ever since VRLA Lead-acid-battery's appearance people come to use the Voltage testing method to determine its quality and life. However careful theoretical analysis and practical experience show that resistance could be a sensitive parameter to determine the quality and life of VRLA Lead-acid-battery. In the paper two kinds of recent resistance testing method are analyzed. According to the analysis finally the modern circuit model of VRLA Lead-acid-battery is questioned.
