摘　　要：根据蓄电池劣化程度SoH的定义,分析了深度放电测量方法的约束性,探讨了交流法在线内阻测试方法的可行性,阐述了内阻与SoH之间的关系,提出利用交流法在线测试蓄电池内阻技术,及时捕捉蓄电池组中工作异常的单体电池,进行个别处理和更换,消除后备电源系统的工作隐患。Taking the definition of accumulator SoH as the starting point,the limitations of deep discharging measuring method and the feasibility of alternating-current on-line inner resistance testing method were analyzed.After elaborating the correlation of inner resistance and SoH,it comes to a conclusion that by the on-line inner resistance testing method,those anomalistic accumulator units can be timely detected and some measures were taken properly so as to eliminate sources of trouble of the back-up power system.

关 键 词：SoH 交流法在线内阻测试方法 蓄电池内阻
