Abstract: To keep battery consistence of performance is a difficult problem, and many factors affect the consistence of performance. In order to improve the consistence of the battery pack, each production link must be controlled strictly. The separator performance is very important for the performance of the battery. In this paper, the battery assembly test was made by use of plate groups assembled under different compression, and the acid absorption saturation was calculated. Furthermore, the related experiments on battery performance were carried out. Based on the analysis of the data obtained from the tests, a theoretical and realistic basis is provided in terms of the battery design, production as well as the processing adjustment.
Key words: assembly compression; acid absorption saturation; acid pumpability; battery consistence of performance

能和隔板有着密切的关系。由于极板、隔板在制作过程中厚度上的差异，相同数量的极板、隔板在装入电池槽后产生的组装压力也不同。组装压力的差异造成了隔板受压缩变形量上的不同，隔板的吸酸量也就不同。同时，电池后期充足电后的抽浮酸作业也会对隔板的吸酸饱和度产生影响，从而最终对电池以及电池组的性能产生影响。
