卫星用锂离子蓄电池性能分析与在轨管理方法

Properties of Li-ion battery for satellite and in-orbit management methods

通过对锂离子电池容量衰降与充电电压、温度、荷电态等因素之间关系的测试,总结出了锂离子电池在卫星上应用的管理方法,包括充电电压调节、长光照期管理和主动温控措施,为提高锂离子电池在轨寿命起到关键作用。

The characteristics of Li-ion battery was tested, including capacity degradation due to end of charge voltage changing,low temperature and state of charge of battery. Li-ion battery in-orbit management methods including battery charge voltage adjustment, solstice storage management, active temperature control were drawn according to the analyse of Li-ion battery properties combining with the characteristics of satellite application, and which are very important to the spacecraft in-orbit life.
