Overall Design And Performance Simulation Of Electric Vehicle

Electric vehicle is one of available ways to solve the problems of energy source's lack and pollution of environment. Pure electric vehicle whose energy is power battery loaded on the vehicle is a kind of zero emission vehicles. In recent years, the upsurge of developing electric vehicle is rising all over the world, and developing to the small amount commercialization production gradually. The development of electric vehicle is relying on the progress of several subjects. Especially, further raising the dynamic performance, increasing the driving range and reducing cost are very necessary. In view of the development funds and times, use the computer to establish the simulation models to simulate the dynamic performance is a better way.This paper, based on one micro electric vehicle, the power form and configuration are defined. According to the dynamic performance, such important parameters as the power of the motor can be calculated by using the knowledge of vehicle, motor and battery. Then the other parameters: reduction ratio, the parameters of battery also can be calculated. Then the performance of dynamics model, wheel model, motor model, battery model and the whole vehicle model are built. Modeling battery needs a lot of test data of battery so experiments on battery are executed. The dynamic performance of electric vehicle are simulated and analyzed. Furthermore, the factors affecting the dynamic performance and the driving range are simulated and analyzed. Finally, the experiment of the dynamic performance is tested. Through the comparison of the simulation results with the experiment results, the simulation models are reasonable and the feasibility of the electric vehicle is verified.
