Abstract: In order to study the current energy consumption status of a range extender electric vehicle, this paper shows the energy consumption conditions and testing methods of the range extender electric vehicle. Based on AVL Cruise software for modeling and simulation, and a relatively efficient and accurate simulation model architecture is proposed to offer dynamic and economic simulation reference in range extend electric vehicle development. After data comparison to confirm the effectiveness of the model, finally, the deviation between the simulated fuel consumption in charge sustainning (CS) mode and the actual test results is less than 1%, which reached the expection and the simulation model can be used in the coming development.
