Performance evaluation of Electric Double Layer Capacitor as energy storage component of microano satellite on the imposition of varied temperature and vacuum conditions

摘要

Electric Double Layer Capacitor often abbreviated EDLC has many characteristics such as high power density , large number of charge -discharge cycles ,ultra-high capacitance , wide operating temperature range, quick and full charge /discharge capabilities which are attractive traits for various applications. Currently it has gained recognition for terrestrial power applications such as Hybrid Electric Vehicles (HEV), Pure Electric Vehicle(PEV), grids back- up systems,etc. This laudable traits can be harnessed for astronautic applications. Spacecraft utilize batteries as storage units for Electrical Power Subsystem (EPS). This paper explains the performance of Electric Double Layer Capacitor under varied temperature condition so as to explain its sailing performance as a replacement for batteries which are hitherto the only storage unit.Depth of discharge of this EDLC has been studied both in vacuum and varied temperature in atmosphere.
