中高轨卫星钴酸锂电池在轨特性分析

Analysis on characteristics of LiCoO2 battery in middle and high orbit satellites

锂离子蓄电池组作为卫星的储能电源,在阴影期和太阳电池阵功率不足时为整星提供能源。分析中高轨锂电池的在轨特性可作为锂电池地面研制的参考。以在轨稳定可靠工作的中地球轨道(MEO)卫星和倾斜地球同步轨道(IGSO)卫星的钴酸锂蓄电池为研究对象,通过长期跟踪研究对象的在轨遥测数据,从单体一致性和长光照搁置周期两方面,对应用于中高轨卫星的钴酸锂蓄电池在轨特性进行了分析。中高轨卫星用钴酸锂蓄电池的在轨特性研究可为后续中高轨卫星锂电池组一致性控制、均衡和搁置管理设计提供重要参考。

Lithium ion battery is a kind of commonly used energy storage power of satellite,which provides energy for the whole satellite during shadow period and solar array power shortage period.The analysis on the characteristics of middle and high orbit lithium batteries could provide references for ground development of lithium battery.The LiCoO2 batteries of MEO and IGSO satellites were studied.Based on the satellite telemetered data followed over time,the characteristics of LiCoO2 batteries used in middle and high orbit satellites were analyzed from the monomer consistency and long-light shelving cycle.The on-orbit characteristics of the LiCoO2 batteries can provide an important reference for the consistent control,equilibrium and shelf-management design of the lithium battery of in middle and high orbit satellites.
