摘　　要：目的研究国内低轨道卫星常用的储能电源镉镍蓄电池组的充退磁效应。方法在零磁场环境下,研究不同的充退磁参数(强度、频率、波形等)与充退磁效果的关系,考察其抗磁污染的能力以及不同的退磁场对其磁效应的影响。结果镉镍蓄电池组比较容易充磁,退磁强度为4.5 m T,频率为1.5 Hz,三方向退磁效果比较好。结论提出了适合镉镍蓄电池组的充退磁参数,提高了航天器部件磁试验的可靠性。Objective To study the effect of magnetizing and demagnetizing of Ni-Cd battery pack power storage commonly used in low-orbit satellite. Methods The relationship between different magnetizing/demagnetizing parameters （frequency, waveforms, intensity, etc.）and the magnetizing/demagnetizing results were analyzed in the zero-magnetic field environment. Furthermore, we studied the capacity of anti-magnetic pollution of battery pack and the effect of different demagnetization field on its magnetic performance. Results The results showed that Ni-Cd battery pack was prone to magnetization, and the three-direction demagnetization effect was better when the demagnetization field was 4.5 mT and the frequency was 1.5 Hz. Conclusion This paper proposed the suitable magnetization/demagnetization parameters for Ni-Cd battery pack, which improved the reliability of spacecraft magnetism control.
