Title Research and Design of Braking Energy System of Electric Vehicle
Abstract
Automobile is one of the most important technological achievements of modern industrial.Human society will develop to the more developed industrial society with the development of automobile industry and related industries .Use of cars, however, has significant impact on the environment, resources and restriction.
As the auto industry to the influence of resources, environment and the development of battery technology, the governments and auto mobile enterprises come to realize energy conservation and emission reduction are the main directions of the future automobile technology development. Development of electric vehicles will be the effective way to solve the problem of resources, energy and environment.
Aiming at these problems, how to use the energy of electric cars more efficiently becomes the key to solve the above problems.Studies have shown that energy in the process of braking is about 53.2% of the total drive energy of a car, braking energy recycling for higher energy utilization has very vital significance. This paper analyzes the electric car of the structure and principle of the braking energy recovery. Analyzes the influence of braking energy recovery constraints from motor vehicle, vehicle battery parameters, environmental factors and control strategies of five aspects.And analyses the electric energy recovery process, put forward for pure electric vehicle braking energy recovery schemes, and the regenerative braking system module was simple modeling and simulation. Analyzed the impact of motor torque and motor models on energy recovery.
