Reducing overall energy consumption has become an imperative in the development of modern motor vehicles. Increasing the energy efficiency of vehicles is achieved in various ways, improving the vehicle aerodynamic characteristics, reducing tyre rolling resistance and increasing the energy efficiency of the propulsion systems. Electric and hybrid vehicles, thanks to the electric propulsion system, have the ability to regenerate energy during vehicle motion, which greatly contributes to increasing the overall vehicle energy efficiency. The ability to regenerate energy depends on the characteristics of the vehicle's propulsion system, but also on the vehicle's driving modes. Energy required for vehicle motion, as well as the potential for energy regeneration, for different driving cycles, are investigated in this paper. Calculation is made for oneB-segment electric passenger car. The vehicle driving is analysed according to the standardized WLTC test driving cycle, as well as one measured driving cycle in Sarajevo. The calculation was performed using Matlab/Simulink and AVLCruise simulation software. The influence of different vehicle driving cycles on energy consumption, as well as the potential for energy regeneration, is pointed out.
