Abstract: Taking an extended-range electric car as example, based on the definite vehicle performance and system architecture, the parameter matching analysis and related experimental study of powertrain including electric drive system, energy storage system, extended-range equipment and control modes so on were carried out. Through the co-simulation of Matlab/Simulink and Advisor, the drivability of E-REV was simulated in the NEDC driving cycle. The simulation and test results show that the generated power is ensured 6 kW, when the engine speed is 2 800 r/min. The SOC curve of battery abides by the control strategy of charge depleting mode, and the torque output of motor meets the driving performance of E-REV. The definite scheme of powertrain can meet the primary performance requirements of E-REV.
