ENERGY EFFICIENCY OF DIFFERENT BUS SUBSYSTEMS IN BELGRADE PUBLIC TRANSPORT.

Research in this paper comprised experimental determination of energy efficiency of different bus subsystems (diesel bus, trolleybus and fully electric bus) on chosen public transport route in Belgrade, Serbia. Experimental measuring of energy efficiency of each bus type has been done based on the analysis of parameters of vehicle driving cycles between stops. Results of this analysis were basis for development of theoretical simulation model of energy efficiency. The model was latter compared with the results of simulation done by "Solaris Bus & Coach" company for the chosen electric bus route. Based on demonstrated simulation, characteristics of electric bus batteries were defined, the method and dynamic of their re-charge was suggested, as well as choice for other aggregates for drive system and technical characteristics for the electric buses were suggested.
