VRLA蓄电池容量落后原因分析

Cause analysis of capacity lagging in VRLA batteries

通讯基站浮充运行的VRLA蓄电池组 ,在使用过程中往往会出现一只或几只蓄电池因容量的过早衰减而导致整组蓄电池性能恶化 ,满足不了用户的使用要求。本文重点阐述了VRLA蓄电池容量落后的产生原因及避免的方法。

In a string of cells for use in float operation in telecommunication station,it is often the case that the performance of the whole string deteriorates during the period of operation and fails to meet the needs of customers,which is caused by premature capacity loss(PCL)in one or several cells.The reasons of capacity lagging in VRLA cells and the measures to avoid the phenomena are elucidated in this paper.
