A General Design for Cd-Ni Battery Activation in-orbit

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。

Abstract:

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 activationautomatically 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.
