Energetic and Ecological Aspects of the Application of Electric Drive Vehicles in Serbia

Abstract

This paper considers the analysis of energetic and environmental aspects of electric drive vehicles application in Serbia. The analysis implies real conditions of road transport and electricity production in our country and evaluates the estimation of energy consumption and CO2 emission (Well-to-Wheel), under the assumption of hypothetical transition from classic internal combustion (IC) engine to pure electric drive of vehicles. For this purpose the real estimations of IC engines efficiency under the road conditions of operation and the global efficiency of electric drive system (electricity production, transmission network, battery and electric motor) were necessary. The results show that in the case of present reality of electricity production from coal (lignite), CO2 emission would be even higher. However, under the assumption of significantly more efficient electricity production (for example using combine cycle of gas turbine – CCGT), CO2 emission would be decreased. In this paper some experimental data of city bus fuel consumption and efficiency measurements are also presented.
