温度对空间用氢镍蓄电池寿命影响分析

Temperature effects on cycle-life of aerospace nickel hydrogen battery

简要介绍了温度对空间用氢镍蓄电池寿命的影响,为电池的设计和在轨管理提供支持,延长电池在轨寿命。通过寿命试验分析,氢镍蓄电池高温下电性能迅速衰降,低温下对寿命无影响,但降低输出功率,建议在轨氢镍蓄电池温度控制为-6^-4℃。

Effect of temperature on cycle-life of aerospace nickel hydrogen battery was introduced. The purpose wasto provide technical support for aerospace nickel hydrogen battery design, on orbit management, and extend thebattery cycle-life. Through the analysis of life test, at high temperatures, the electrical performance of the battery wasrapidly declined. At low temperatures, the cell cycle-life was not affected, but the output power was reduced. It wasrecommended that the temperature of Ni-H2 battery could be controlled from -6 to -4 ℃.
