Abstract

U ovom radu analizirano je nekoliko ciklusa vožnje i potrošnja energije kroz te cikluse kako bi se odredio optimalni kapacitet baterije BEV tegljača s poluprikolicom. Razmatrala se situacija korištenja tegljača s poluprikolicom po principu ˝poštanske kočije˝ gdje se tegljači i vozači izmjenjuju, a poluprikolice uz što manje zaustavljanja putuju između čvorišta. U sklopu analize određeno je osovinsko opterećenje kojim se odredila maksimalna masa tereta koju vozilo može prevesti i masa baterije, a da su dopuštena osovinska opterećenja zadovoljena. S povećanjem mase baterije pada masa prevezenog tereta, ali raste domet i obratno. Razrađeni su razni ciklusi vožnje s obzirom na vremena rada i odmora vozača s raznim udaljenostima čvorišta, emisija i brzina transporta kako bi se usporedile prednosti i mane BEV tegljača s poluprikolicom u odnosu na tegljač s Dieselovim motorom.

Abstract (english)

In this paper, several driving cycles and energy consumption through these cycles were analyzed in order to determine the optimal battery capacity of a BEV tractor-trailer. The situation of using a tractor-trailer according to the ˝stagecoach' principle was considered, where tractors and drivers alternate, and semi-trailers travel between nodes with as few stops as possible. As part of the analysis, the axle load was determined, which defined the maximum load mass that the vehicle can transport and the mass of the battery, and that the permitted axle loads are met. As the weight of the battery increases, the weight of the transported load decreases, but the range increases and vice versa. Different driving cycles with regard to driver work and rest time with various hub distances, emission and transport speed were considered to compare the advantages and disadvantages of a BEV tractor with a semi-trailer compared to a diesel engine tractor.
