The influence factor analysis of energy consumption on all electric range of electric city bus in China

For the electric city bus demonstration operating in Chinese city, based on establishing the system model, this paper uses constant speed and Hefei of Anhui province of China as driving cycles, mainly analyses the influence of the vehicle mass and the average power of the electric auxiliary on the endurance mileage and energy consumption. Simulation results show that, the electric bus studied in this paper driving at the constant speed of 30km/h, if the vehicle mass increases per 1000kg, the power consumption increases about 3%~4%. If the auxiliary power increases per 5kW, the power consumption increases about 15%~55%. In Hefei city bus driving cycle, if the vehicle mass increases per 1000kg, the endurance mileage decreases about 1km, but the power consumption increases about 3.5%. If the auxiliary power increases per 5kW, the power consumption increases about 22%.
