Hybrid and Electric Powertrains of the Trucks
Mrkva, Filip ; Řehák, Kamil (referee) ; Prokop, Aleš (advisor)
This bachelor's thesis deals with current trends in construction of electrified powertrains of trucks. Individual concepts are described and divided according to the arrangement and degree of electrification of the drive. Based on the most actual information from the manufacturers' websites, the parameters of the components used in real vehicles equipped with alternative powertrains are analysed. Real powertrains are evaluated in terms of usability in operation, operating costs, and environmental friendliness. Advantages and disadvantages of hybrid, battery and hydrogen trucks compared to conventional vehicles with internal combustion engines are discussed. Furthermore, the direction in which the discussed branch of the automotive industry will continue to develop is mapped, as well as the most significant obstacles and challenges associated with it. As part of the work, battery cars with an integrated electric axle were evaluated as the most promising for a relatively simple drive design, easy charging, and sufficient range for many applications. Key problems in the developing electric vehicle industry were also pointed out, which are mainly the low energy density of battery and hydrogen cells together with the energy-demanding production of batteries.
