镉镍蓄电池组是我国小卫星的主要储能装置,合理准确的蓄电池组在轨性能评估技术可以有效地预计电池组运行状态。介绍了在轨评估对象的选取方法,研究了电压评估、电量评估技术,通过在轨实际数据对上述方法进行了验证。该评估技术为空间用镉镍蓄电池组在轨性能评估技术提供了新的思路,可作为制定在轨管理策略、采取在轨操作的参考。
Nickel-cadmium batteries are the main energy storage devices for small satellites in our country. The reasonable and accurate battery in-orbit performance evaluation technology can effectively predict the battery operating status. The selection method of on-orbit evaluation object is introduced. The voltage evaluation and power evaluation technology are studied. The above method is validated by on-orbit actual data. The evaluation technology provides a new idea for on-orbit performance evaluation technology for cadmium-nickel battery in space, and can be used as a reference for in-orbit management strategy and on-orbit operation.
