摘　　要：经过长期在轨运行,卫星用氢镍蓄电池组单体之间性能会发生离散,性能离散会导致蓄电池组出现快速衰减、工作寿命缩短等问题,故当性能离散较大时,需要对蓄电池进行在轨维护,太阳同步轨道卫星由于每天经历地影期,并且光照时间短,目前没有一种在轨维护方法,提出了一种适合太阳同步轨道(SSO)卫星氢镍蓄电池在轨维护技术,实践证明技术合理、有效。Long-term working in-orbit, performance deviations among the cells in aerospace applications of nickel-hydrogen batteries spread,and the deviations cause loss in performance and cycle life etcs. It is essential to recondition batteries in-orbit, when performance deviations overrun definite range. Sun-synchronous orbit satellites go through eclipse periods every day, and sunlight periods is short. There is no reconditioning techniques for sun-synchronous orbit satellites nickel-hydrogen batteries at present. A kind of reconditioning technique in-orbit for sun-synchronous orbit satellites nickel-hydrogen batteries was put forward. The good performances of nickelhydrogen battery during in-orbit flight lifetime after reconditioning show the reconditioning technology for battery is profitable for sun-synchronous orbit satellites.
