摘　　要：针对月球卫星工作模式多,功率需求变化大,自主控制能力要求高的特点,防止蓄电池出现欠充电、过充电,确保卫星供电安全,文章提出了以电子电量计控制为主、压力控制为辅的氢镍蓄电池在轨自主管理技术,包括充电控制模式、多模式多速率充电管理、全光照期充电管理和月食充电管理等内容,并给出了电池在轨测试情况。在整个任务飞行过程中电池以优异的性能在轨运行,实践证明月球卫星氢镍蓄电池在轨管理技术合理、有效。Considering that the requirements for multiple work modes, variant power and highly autono- mous control are the significant characteristics for lunar exploration satellite, and aiming at protecting the battery form short charging and over-charging and protecting the power supply security of the satellite, an in-orbit management technology {or nickel-hydrogen battery is raised in this paper which uses in-orbit autonomous control mainly by cou｜ometer with auxiliarily pressure control. Furthermore, charging control mode, multiple charging mode and multiple charging rate manage- ment, and charging management during long sunlight period and lunar eclipse are explained, and the in-orbit testing results are given. The good performances of the nickel-hydrogen battery dur- ing in-orbit flight lifetime show that the in-orbit management technology for battery is profitable for lunar exploration satellite.
