基于Advisor纯电动汽车制动能量回收评价研究

Evaluation Methods of Braking Energy Recovery based on Advisor

制动能量回收是体现电动汽车优势和特点的重要技术,是决定多种形式电动汽车能耗经济性、整车安全性的共性关键技术。本文针对装有制动能量回收系统的某东风牌纯电动客车,在分析能量流的基础上,提出了以回收的制动能量和最大理论制动能量的比值作为制动能量回收系统的评价指标,并利用仿真软件advisor,模拟计算了这款车在NEDC循环工况下的制动能量回收效率,并结合参数进行分析。

Braking energy recovery is an important technology to embody the advantages and characteristics of electric vehicles, and it is the key technology to determine the energy consumption economy and the safety of various kinds of vehicles. This paper aimed at a pure electric bus with a brake energy recovery system of Dongfeng on the basis of analysing the energy flow proposing to the ratio of recovery of braking energy and the theoretical maximum braking energy as an index to evaluate the braking energy. By using simulation software Advisor, it calculated the efficiency of braking energy recovery of this bus which is in the NEDC cycle and combined with parameters analysis.
