Biziraupen estimazio modeloa garraio astuneko aplikazioetan erabiltzen diren superkondentsadoreentzako

Abstract

Kutsadurak sortutako arazoen eraginez, azken hamarkadan efizientzia handiagoko garraio aukeren beharraareagotu da. Testuinguru honetan, metatze elektrikoko sistemekin bultzatutako garraioek aukera oso aproposaaurkezten dute. Efizientzia handiko eta metatze sistemen bidez bultzatzen diren garraioen adibide argi bat tranbiakdira. Hala ere, eskuragarri dauden metatze teknologiek merkatu mailan berme altuagoa eskaini ahal izateko,pairatzen duten zahartzea aurreikustea garrantzitsua da. Hain zuzen ere, lan honek mota honetako aplikazioetanerabiltzen diren superkondentsadoreen biziraupena estimatzeko modelo bat aurkezten du.Modeloa baldintzaerrealistetan burututako froga esperimentaletan oinarriturik garatu eta balidatu da. Azkenik, ikerketa kasu bataztertu da benetako tranbia baten operazio profila erabiliz.

Due to the high pollution levels, in the last few years the need of improving the efficiency of the transportationsector has increased. In this context, transport applications powered by electric storage systems emerge as a veryconvenient solution. Tramways are a clear example of high efficient transport applications powered by energystorage systems. Nevertheless, in order to achieve a higher reliability in the market, it is important to properlyforesee the ageing effect that the existing storage systems suffer. This paper presents an ageing model to estimatethe lifetime of supercapacitors, which are widely used in the mentioned transport applications. The model isdeveloped and validated based on experimental tests developed in real application conditions. Finally, a studycase is analyzed applying the operation profile of a real tramway to the proposed model .
