摘　　要：对阀控式铅酸蓄电池(VRLA)的充电制度作了简单介绍,指出在不同的充电制度下,电池的循环寿命相差甚大。本文采用恒压限流和分阶段恒流充电方式对电池进行80%DOD容量循环寿命的试验。试验结果表明,采用分阶段恒流充电方式的蓄电池循环寿命较长。The charging mechanisms for valve-regulated-lead acid （VRLA） batteries were briefly reviewed. It indicated substantial differences in cycle lives of VRLA batteries at various charging mechanisms. Two typical methods, constant current constant voltage （CC-CV） as well as phased constant current charging were adopted in the cycle life test at 80 % DOD. The results showed that the cycle lives of VRLA batteries with the latter method were longer.
