Research on modeling and simulation of pure electric vehicle

At present, with the development of science and technology, the concept of environmental protection has also become popular, and electric vehicles have received widespread attention for their advantages of energy saving, environmental protection and good driving quality. In this paper, the driver model, battery model, motor model, transmission model and body model of electric vehicle are established in simulink, and all parts are connected and combined to form a vehicle model. After the parameters of each part are set, the electric vehicle is simulated under the NEDC cycle condition to explore the vehicle’s speed following, driving distance, 100 km acceleration and other performance, as well as the change characteristics of battery soc. The simulation results show that the electric vehicle has good output characteristics. At the same time, the driver mode in this paper adds the energy brake recovery function, which increases the driving distance by 23.1% when the energy brake recovery efficiency is 0.3 compared with the vehicle without this function.
