nonrenewable energy crisis aggravated, with new energy efficient electric vehicles as a power has bee the most important direction of development. Today, the technology at home and abroad in the field of electric vehicles in the rapid development, some wellknown big car panies 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 lowspeed pure electric vehicles, calculation and simulation, the main parameters are calculated based on the performance requirements of the lowspeed pure electric vehicles and matching custom conditions calculation models, the establishme
