Simulation Study Of Electric Vehicle Energy Storage System Based On ADVISOR

People have realized the importance of environmental protection because of the serious environmental pollution in the world and the constant depletion of petroleum resources.In the case of environmental pollution and energy shortages,people have put forward more requirements towards in the car industry,and the car industry has faced challenges.Meanwhile,using clean and environment-friendly cars can reduce the pollution to the environment.Therefore,the electric cars that have the characteristics of energy saving,environmental protection,safe and economic have made people pay attention.Nowadays,in the world many countries are being studied electric cars,particularly developed countries.And the development of electric vehicle technology must be considered to improve the performance requirements of the storage system to store energy.The short mileage and higher fuel properties of electric vehicles affect their development.Meanwhile,considering the cost of electric vehicle,it is required to use software to simulate electric vehicles.It's important to study the impact of different storage systems on electric cars,mainly in terms of the driving rang and the dynamics of the car.Through the dynamic analysis of the electric car and the design of the parameters of the storage system to choose the appropriate storage.Through the analysis of the operating characteristics of different energy storage system,choose what energy storage system and the electric car the best match.In this paper,electric vehicle mechanics and multiple energy storage systems are analyzed,which lays a foundation for the modeling of electric vehicles.Meanwhile,different energy storage systems of electric vehicles are modeled in MATLAB.And the model of super capacitor,lithium ion battery and spring energy storage and composite energy storage is established.At the same time,simulation software is used to simulate these energy storage systems.The influence of energy storage system on electric vehicle is analyzed by simulation study of these energy storage systems and composite energy storage systems.Through analysis of the performance of the energy storage system,it is concluded that the spring of the advantage of elastic energy storage in electric cars.
