高轨道氢镍蓄电池组在轨性能评估模型

Evaluation model for GEO Ni-H2 battery status

氢镍蓄电池(Ni-H2 Cell)是目前在轨应用较多的一种空间储能电源,具有安全可靠、循环寿命长的特点。对80 Ah氢镍蓄电池寿命试验数据进行了梳理,归纳总结了高轨道应用氢镍蓄电池的容量衰降模型和电压衰降模型,可用于卫星氢镍蓄电池组在轨性能的近似评估,更好地了解在轨氢镍蓄电池组的性能变化趋势,为整星供电安全提供有力保障。

Ni-H2 Cell is served as space energy storage power source for its safety, reliability and long cycle life. The life test data of DFH-4 80 Ah Ni-H2 battery was disposed and capacity degradation model and voltage degradation model for Ni-H2 battery was summarized, which could be used to simply evaluate the status of on-orbit DFH-4 Ni-H2 battery. The performance trend of on-orbit Ni-H2 battery could be comprehended better. The safety of power supply for the satellite was consequently ensured.
