Research on Key Influencing Factors of Endurance Mileage of Battery Electric Vehicle

Abstract

Electric vehicles have received much attention from the government, businesses, and customers due to their inability to meet stated driving ranges. In this paper, from two dimensions of energy and energy consumption are the main factors causing the trip range of electric vehicles is studied, through the experimental study on the system analysis, simulation and calculation the travel distance of the influence of different test cycles, and questioned by consumers more high temperature, low temperature and high speed travel distance of typical driving cycles fluctuate in-depth research. The results show that the energy consumption and range of electric vehicles are influenced by many factors, and the driving cycle is the main reason for the difference between the certified energy consumption and the actual energy consumption of electric vehicles: the driving range of CLTC is close to that of NEDC, but significantly lower than that of WLTC. The increase of wind resistance at high speed was the main factor for the decrease of driving range, and the reduction of air conditioning energy consumption, battery heat preservation heating energy consumption and discharge capacity was the main reason for the decrease of driving range at low temperature. It is suggested that the government improve relevant testing cycles, add high and low temperature and high speed strong inspection and certification programs, and mark energy consumption labels, and strengthen public awareness of key influencing factors of electric vehicle driving range through various publicity channels.
