Abstract: Aiming at the problem of powertrain parameter matching in the research and production of the range extended electric vehicle (REEV), the powertrain parameter of REEV was designed based on the targets of the vehicle dynamic performance and the driving range. Especially, the motor system, the battery system and the engine generator system were studied. And the model with a constant power management strategy was made on the AVL CRUISE simulation platform to verify the vehicle dynamic performance and the driving range. The simulation results of the maximum velocity, the acceleration performance and the climbing performance indicate that the powertrain parameter matching meet the goal of vehicle dynamic performance. In addition, the simulation results of the of pure electric and extended range driving range at the speed of 10 km/h and 15 km/h indicate that the powertrain parameter get the goal of the driving range.
