摘要
Abstract
As the most important energy storage instrument on low-orbit satellite,the batteries' performance directly influence the security and stability of satellite,and appropriate control strategy for battenycharging could effectively delay the performance degrade of batteries which would prolong satellite's lifetime.The weakness of previous charging strategy was analyzed,on the base of the power supply system on low-orbit satellite,and a charging strategy of two stages current-limiting control realized by computer software was proposed,which could control the switching of charge during one or two stage of current-limiting control by comparing the current quantity of electricity and transfer stage threshold.The parameters of this method could be adjusted in orbit,which would diminish the impact of voltage fluctuations by load current change.The method enhances the flexibility and safety of charging control on low-orbit satellite.The whole power supple system works more stability than before,and the strategy is validated to be feasible through test on orbit.关键词
