Pitoňák, Adam ; Míša, Jiří (oponent) ; Hejtmánek, Petr (vedoucí práce)
This diploma thesis sets itself into the task of presenting a conceptual design of a powertrain system intended for a small electric vehicle of the L6e category. As a part of this thesis, in the initial part of this work, a survey of components and their optimal arrangement in the powertrain system of a small electric vehicle was carried out. Subsequently, after the presentation of the possible components of the powertrain system, testing of these variants was carried out, both form a mechanical and an electrical point of view, to guarantee the compatibility of the individual parts of the vehicle´s powertrain system. After the evaluation, the optimal variant of the drive system, intended for the concept on a small electric vehicle “Nanos” was selected. To determine the acceleration characteristics and the range of a vehicle equipped with such designed powertrain system, series of acceleration tests as well as vehicle range test according to the first part of the official WMTP cycle, intended for vehicles belonging to the category L6e, were performed. The resulting values of the vehicle´s acceleration and range tests are subsequently compared with the values of already existing vehicles belonging to the same category, thus enabling an overall evaluation of the powertrain system concept.
