Abstract: To reduce the energy consumption and extend the driving range of extended-range electric vehicles, an extended-range electric vehicle with different modes is employed to analyse the energy consumption characteristics and driving range under different driving cycle. The vehicle working mode is divided into hybrid mode and pure electric mode. The results show that under CLTC, the difference between the actual speed and the required speed in the two operating modes is the smallest. Driving resistance is the main factor that affects the energy consumption and driving range of the vehicle; brake recovery also has a certain impact on driving mileage. In the pure electric mode, the driving range of the vehicle is the longest under the NEDC. And in the hybrid mode, the engine loses the highest energy. These results are helpful for the study of energy consumption law of extended-range electric vehicles and the design of energy management strategies.

Keywords: extended range electric vehicles; energy consumption; driving cycle; energy management.
