电动汽车再生制动系统回收特性与能量流分析

Recovery Characteristics and Energy Flow of Electric Vehicle Regenerative Braking System Analysis

装有再生制动系统的电动汽车可以回收利用原本被制动系统消耗的能量,从而降低能耗且提高整车的经济性。通过分析再生制动系统制动时的能量流关系,参考已有的评价方法,提出了一套能够有针对性的全面的反应再生制动系统回收特性的评价指标,并搭建了再生制动试验平台,以某电动汽车为例,通过试验明确了其再生制动系统的能量流与回收特性的关系,对再生制动系统的研究与开发提供参考依据。

Electric vehicle and hybrid electric vehicle equipped with regenerative braking system can recycle the energy originally consumed by the braking system to reduce energy consumption and improve the vehicle＇s economy. Through analyzing the energy flow relationship of regenerative braking system braking and referring to the existing evaluation methods,a set of evaluation index which can targetedly and comprehensively response regenerative braking system recovery characteristics was put forward. Taking a electric car for example,through experiments the relationship of recovery characteristics and the regenerative braking energy flow was made clear,and the reference for the research and development of the regenerative braking system was provided.
