摘要
提出了一种卫星镉镍蓄电池在轨活化通用化设计与实现方法,利用卫星软件根据实时遥测数据,自主进行镉镍蓄电池在轨活化处理;解决了传统航天器地面采用预设V-T曲线进行镉镍蓄电池的充放电人工控制时,由于电流遥测频率较低且负载工作电流变化模式多,境外的参数无法实时获取等原因,无法获取准确的充放电电量,不易通过深放电实现镉镍蓄电池在轨活化处理的问题;进一步对该方法进行通用化设计,可适用于采用电量计控制的各种航天器镉镍蓄电池,提高镉镍蓄电池寿命末期输出能力,延长航天器电池使用寿命。
Provided a method of designing and realizingthe General Onboard Software for Cd-Ni battery activation in-orbit.In this scheme,the onboard software completes the Cd-Ni battery activationautomatieally with real-time telemetry data.It solved the problem that the ground controller can＇ t forecast and control the traditionalspacecraftCd-Ni battery activation process exactlywith V-T curve because of lack of real-time date overseas,the low frequency of telemetry and the working current changes all the while.And after the generalize designing,it is suitable for all kinds of spacecraftwhich used Cd-Ni battery,and improve the power supply ability and prolong the life of battery.
