Theoretical analysis of electric vehicle energy consumption according to different driving cycles

Abstract

The paper presents a theoretical analysis of energy consumption according to selected driving cycles. The aim of the study was to analyse the impact of various acceleration and speed values on the energy consumption of an electric vehicle. The object of the study was the Nissan Leaf vehicle, equipped with a synchronous AC electric motor. The research methodology involved creating a mathematical model based on the technical and operational parameters of the vehicle. The characteristics of the torque of the electric motor of the test object were used, the basic and additional resistance values were determined using the vehicle's technical parameters such as: complete vehicle kerb weight plus the mass of passengers and cargo, useful battery capacity, width and height, type of a drive system used, wheel sizes. Finally, the energy consumption for each driving cycle was determined. According to the NEDC cycle, it amounted to a maximum of 15.6 kWh/100 km and was by 4 percent higher than the producer stated.
