With the severe energy shortages, environmental pollution , as a zero-emission green transportation - pure electric vehicles are increasingly favored by the major automotive manufacturers has become the hot spot in today's society the automotive world competing to develop . Decades , with the traditional auto industry continues to grow and develop , the countries of the world are facing serious challenges in the energy and environmental crisis . The emergence of pure electric vehicles can effectively solve the energy and environmental crisis . In addition, the smooth running of pure electric vehicles , low noise , component layout flexible and diverse , easy maintenance , energy efficiency advantages , more and more governments and people's attention and love making pure electric vehicles , Hyundai Motor Development direction. In this paper, Mazda6EV design prototype , pure electric vehicle powertrain design . Powertrain as the core system of pure electric vehicles , mainly to complete energy conversion and energy transfer . Current technical conditions , the research objectives of this article powertrain design reasonable , reasonable choice of powertrain - related parameters of the various components , the various parameters to achieve optimal matching , meet vehicle dynamic requirements and vehicle continued mileage requirements in the case of the battery reaches a minimum. In this paper, based on the force of the vehicle , vehicle dynamics model of the vehicle . The establishment of the various components and vehicle Simulink simulation model based on the Advisor , such as power motor , battery simulation model based on the relationship between the various components . Simulation model of vehicle performance . Vehicle dynamics and driving range is the performance of pure electric vehicles . Simulation results of power and driving range , the analysis of the power of the motor , the match between the main parameters of the battery capacity and the transmission ratio of the transmission , and the various parameters of the dynamic , driving range impact on this basis parameters reset , optimize . Simulation again , the optimization results to reasonable validity verified through simulation of vehicle performance data compare before and after optimization , optimization results , and ultimately determine the optimal matching of powertrain design and the main parameters of the various components of value .
