摘　　要：对几组不同型号的电池进行循环寿命试验,以研究高型和低型电动助力车电池组的循环寿命的差异。高型电池组的循环寿命只有低型电池组的50%甚至更短。循环寿命存在较大差异的原因,主要是电解液分层所致,高型电池组的电解液比低型电池组的更易分层。Cycle life test of some groups of battery with different types was taken to study the difference between high-type and low-type batteries for electric bicycle.The cycle life of high-type batteries was only 50% of that of low-type batteries,even shor-ter.The main reason of the big difference of cycle life was the stratification of electrolyte.The electrolyte of the high-type batteries was easier to stratify than the low-type batteries.
