摘要
采用AGM隔板的VRLA动力型电池极群组装压力的大小及一致性是影响电池性能、电池组性能一致性的重要因素。本文介绍了用材料试验机检测电池组装压力的方法,及在不同的极群组装压力下组装的电池、电池组性能上的差异。AGM-VRLA电池的循环寿命与组装压力有很大的关系。理论实践证明,给极群组施加一个较高的压力时,可以明显提高VRLA电池的循环使用寿命,但是超过一定压力后,继续增加组装压力,电池的循环寿命反而下降。
The consistency of group assembly pressure of AGM VRLA power battery is a important inffluence factor on the performance and consistency of VRLA batteries. This article introduced the method to test assembly pressure by the material testing machine, and the difference in performance batteries assembled at different group pressure. The cycle life had a very big relation with assembly pressure of AGM VRLA batteries. The theory and practice proved that have proved that the cycle life of VRLA battery was prolonged when the group pressure was higher, but the cycle life would be decreased if the assemble pressure continued to be increased beyond a certain pressure value.
