Resumo

This paper presents a comparison between an electric vehicle and a vehicle with an internal combustion engine regarding carbon dioxide (CO2) emissions and energy consumption, whether in electric or chemical form (contained in the fuel). For this analysis, the AVL Cruise software was used to simulate two similar vehicles, one electric and the other with an internal combustion engine. Some parameters adopted in the simulation were: flat, straight road, a 70 kg vehicle driver and driving cycle according to the U.S. FTP-75 standard. The CO2 emissions from the electric vehicle were calculated using the CO2 emission factors from electricity generation in Brazil and in other countries in order to compare the use of the electric vehicle in places with different power generation. For this, the CO2 emission factors used were the media from the values between 2006 up to 2008. With regard to energy consumption, the vehicle with internal combustion engine had a consumption of 0.6830 kWh/km and the electric vehicle 0.0951 kWh/km. The results showed that the electric vehicle emits about 52 times less than a vehicle performed with an internal combustion engine. In Greece, this value decreases to 2, and for Mexico, US, Turkey, Ireland, UK, the electric vehicle emits 3 times less than the conventional vehicle performed which the emissions correspond a 182 gCO2/km.
