| Abstract: |
| 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. |
