摘　　要：氢镍蓄电池作为储能电源广泛的应用于空间能源领域,氢镍电池在搁置过程中会有自放电,通过对不同充电量、温度和搁置时间的研究,找到了自放电率与搁置时间、充电容量和环境温度的关系;找到了不同温度、不同充电量下电池的充电效率,可以通过选择不同的使用制度大大提高电池的使用效率。NiH2 cells are widely used in space filed.However,the self-discharge has the bad influence on the NiH2 cell performance.The relationships between self-discharge rate and storage-time and between charge-capacity and temperature were found out from the studying on difference storage-time,charge-capacity and temperature.The charge efficiency of cell in different temperature and charge-capacity was gained,and the use efficiency of the cell could be greatly improved by choosing the proper charge-discharge mode.
