空间锂离子蓄电池的特点及其管理模式

Space electrical power subsystem with lithium-ion battery

根据锂离子蓄电池的特点,从组成空间电源系统的角度,分析了采用锂离子蓄电池的空间电源系统的特点以及与现行采用氢镍蓄电池组和镉镍蓄电池组在系统设计上的不同。阐述了从电池性能和电池组在轨管理两个方面必须解决的技术问题,以满足未来空间应用的需要。

Properties of lithium-ion cell were introduced. Differences of using lithium-ion battery from nickel-hydrogen and nickel-cadmium battery in design of the electrical power system（EPS） in space were studied. In order to meet requirements in future space applications, some technical problems about performances of cell and battery management in orbit must be solved.
