Today, the technology at home and abroad in the field of electric vehicles in the rapid development, some well-known big car companies have developed different types of electric products available. But while electric vehicles into your life, you also need to solve a lot of problems. In this thesis, the dynamic parameters of the low-speed pure electric vehicles, calculation and simulation, the main parameters are calculated based on the performance requirements of the low-speed pure electric vehicles and matching custom conditions calculation models, the establishment of the simulation model, and in the AVL-cruise software simulation, the simulated dynamic performance, verify the calculated parameters, the model the dynamic performance of electric vehicles; does not consider issues related to economic, technical analysis corresponding to the maximum speed, driving mileage, maximum acceleration, average speed and other factors; further research and to explore the main driving force to determine these p
