D05 地球・天体観測技術実証衛星「TSUBAME」の電源系フライトモデル開発(超小型衛星)

Matunaga Laboratory at ISAS/JAXA and Tokyo Institute of Technology has developed a 50kg class micro-satellite called TSUBAME. In this paper, some of improvements of EPS at flight model phase are reported. Specifically, how to estimate depth of discharge by measuring cell voltage, how to manage a battery pack and passive cell balancing with resisters are focused.
