混合动力公交车制动能量回收系统分析

Analysis on Braking Energy Recovery System of Hybrid Bus

城市公交频繁的制动带来了巨大的能量损失,采用再生制动来回收制动能量是增加电动汽车续驶里程的有效方法之一。简述了混合动力汽车再生制动系统的国内外现状以及国内公交车运行系统的工况;从整车系统的角度分析了制动能量回收与再利用控制原理,并在此基础上说明了混合动力公交车节能的途径,为提高电动汽车驱动效率、合理利用有限能量提供了技术支持。

The city bus frequent braking is of great energy loss. The use of regenerative braking to recover braking energy is one of the effective ways to increase the driving range of electric vehicles. The status quo of hybrid vehicle regenerative braking system at home and abroad was outlined as well as domestic bus system operation conditions, From the perspective of the vehicle system, the principle of the braking energy recovery control and re-use ways were analyzed. It provides technical support for improving electric vehicle drive efficiency and the rational use of the limited energy.
