Nickel-hydrogen Battery In-orbit Management Technology and Performance Analysis for Lunar Satellite

Considering that the requirements for multiple work modes,variant power and highly autonomous control are the significant characteristics for lunar exploration satellite,and aiming at protecting the battery form short-charging and over-charging and protecting the power supply security of the satellite,an in-orbit management technology for nickel-hydrogen battery is raised in this paper which uses in-orbit autonomous control mainly by coulometer with auxiliarily pressure control.Furthermore,charging control mode,multiple charging mode and multiple charging rate management,and charging management during long sunlight period and lunar eclipse are explained,and the in-orbit testing results are given.The good performances of the nickel-hydrogen battery during in-orbit flight lifetime show that the in-orbit management technology for battery is profitable for lunar exploration satellite.
