摘　　要：探讨测定AGM电池饱和度的方法,以及饱和度对阀控式AGM电池性能的影响。隔板饱和度过高或过低都对阀控式AGM电池的内阻、低温放电性能、50%DoD循环寿命有较大影响。饱和度过低,电池内阻增大,低温放电性能变差。饱和度过高,电池50%DoD循环寿命变短。这是由恒压限流充电时,电池充电不足导致的。This paper discussed the test method for saturation and the effect of saturation on the performance of VRLA battery.The results show that too high or too low saturation has great influence on the internal resistance,low temperature discharge and 50%DOD cycle life.The lower saturation leads to the increase of internal resistance and the deterioration of low temperature discharge performance.The higher saturation leads to short 50%DOD cycle life which is caused by the VRLA battery has insufficient charge.
