摘　　要：由于汽车怠速时燃油消耗高,导致车辆经济性降低,汽车怠速停止系统通过自动关闭发动机来节省燃油,提高车辆燃油经济性。提出了汽车怠速停止的概念,在介绍汽车怠速停止系统的结构组成与工作原理基础上,对系统使用电池的情况进行了分析,设计了适合汽车怠速停止系统的复合储能装置,并对储能装置的荷电状态、电容和DC/DC转换器进行了参数设计。对改装后某一车型,利用硬件在环仿真试验系统,在ECE15+EUDC城市循环工况下,进行仿真试验。试验结果表明,设计的储能装置的能量回收率较高,对系统电流能够进行有效控制,降低了对电池的冲击,提高了系统使用寿命,能够较好地适用于城市工况。A vehicle at idle speed consumes much fuel, leading to low economy. The Idling Stop System is a device that automatically stops the engine to reduce fuel consumption. Basing on the idling stop concept, the paper introduces the basic structure and the working principle of this id- ling stop system, analyzed batteries used by the system and designed the storage device for the idling stop system, and described the state of electric charging, capacitance and DC/DC converter parameters of the energy storage device. The storage device is simulated under ECE15 ＋ EUD on the simu- lation experiment system. The results showed that the energy recovery rate has been improved great- ly, and that current can be controlled effectively. This device prevents the battery against shock, and so prolongs the service life of batteries.
