The content of this thesis is analysis of energy flows of the propulsion system in plug-in hybrid utility vehicle. Theoretical part of the thesis deals with electrically assisted turbochargers, which can positively influence engine characteristics. The following part analyses given diesel engine and utility vehicle in simulations in GT-Suite software, with simulations being performed on WLTC driving cycle. The results of the simulations demonstrate the relation between the usage of electrical and fuel energies and the driving cycle and show the engine operation points. By using optimal battery capacity, it is possible to save according to driving cycle more than 50 % energy consumed by the engine, directly influencing the fuel consumption. The results are possible to use as a guidance for moving the engine operation points and for sizing of the battery pack of hybrid utility vehicle according to real life application.
