摘要汽车工业的可持续发展面临着能源和环境保护的双重的压力,零排放、零污染的电动汽车因此成为了世界各国大力发展的方向。然而,电动汽车一次充电的续航里程远远小于传统的燃油汽车,这一严重不足影响了电动汽车的迅速推广和产业化。而再生制动是解决电动汽车续航里程不足的有效方案之一。而在再生制动的运用当中,如何能够高效的回收和利用再生的能量是非常主要的问题,本文就主要分析了不同制动方式下能量回收系统的不同状态。文中简述了电动汽车再生制动系统的基本结构和工作原理,为分析回收率的不同奠定了基础。
首先介绍了电动汽车再生制动系统研究的背景和意义、国内外发展现状等并讨论了电动汽车队驱动系统的一些基本要求,利用简化模型达到的仿真目的,能够对再生制动的回收系统做基本的模拟运行。10415
然后通过matlab中的simulink搭建直流电机模型仿真了电动汽车不同制动方式下再生制动的状态,并对回收系统的结构进行了分析,得到了关于回收率的数据并予以处理。通过图表的形式使得不同制动方式下再生制动能量回收率的状态得以体现。
最后本文通过对直流电机各项参数的重新设置对提升再生制动能量回收率的方法进行了总结以及分析。为提升回收率提供了有效途径。

Title Research on regenerative braking system of
electric vehicles
Abstract
Sustainable development of the automotive industry is facing the dual pressure of the energy and environmental protection, zero emissions; zero-pollution electric cars thus become vigorously develop the direction of the world. However, the mileage on a single charge of electric vehicles is far less than traditional fuel vehicles, this serious lack of impact of rapid promotion and industrialization of electric vehicles. Regenerative braking is an effective solution to solve the electric vehicle mileage one. The use of regenerative braking, how can the efficient recovery and use of renewable energy is a very major problem, this paper mainly analyzes the different states of a different brake energy recovery system. This paper outlines the basic structure and working principle of the electric vehicle regenerative braking system, which also laid the foundation for the analysis of recovery of different.
The papers outlines the background and significance of the electric vehicle regenerative braking system, development in the world and discuss some basic requirements of the drive system of electric vehicle fleet, that the use of the DC motor can achieve the desired simulation state, capable of regenerative braking recovery system to do the basic simulation run.
In this paper, the Matlab simulink build a state of regenerative braking in the braking mode of the DC motor model simulation of electric vehicles, and recovery system, structure analysis, on the recovery of data and handle. Through the chart in the form of the state of regenerative braking energy recovery to be reflected in different braking mode.
Finally, through the re-set the parameters of the DC motor to a summary and analysis to enhance the regenerative braking energy recovery. Provides an effective way to improve recovery.
