When starting up the cars, a big current is required quickly from storage batteries, and if this situation repeats for many times, capacitance of the batteries will decrease seriously. So they must be maintained or replaced periodically and an extra cost is needed. In the cold areas and winter time, temperature has such a heavy influence on storage batteries that they can’t work normally. On the contrary, supercapacitors have such a better performance than traditional storage batteries of fast charging and discharging, high efficiency and reliability, free maintainance that they are suitable to spaceflights, aviation aircrafts and vehicles working in a terrible environment. Howerver, supercapacitors are new enery storage devices that their characteristics are not very clear, so they can’t be used widely. This thesis aims at establishing a practical electrical parameter model for the supercapacitor through experiments and simulations, analyzing the possibility and conditions of supercapacitor resonance, and providing some theoretical proof for designing satellites and superhigh power pulse sources of new arms based on a thorough analysis of the effect that supercapacitor’s parameters have on the power sources. At the same time, a calculative method for batteries- supercapacito
