摘　　要：为提高混合动力系统整体性能,实现高效能量回收,分析某重型越野车辆驾驶循环工况中制动过程的功率与能量分布,从制动能量回收率与电机参数出发讨论对储能装置的性能要求.提出电池组-超级电容复合储能装置的参数匹配方法,针对21 t级试验样车混合动力系统进行实例计算,论证锂离子电池组与超级电容组成的复合储能装置的性能.实例计算与道路试验结果表明:匹配的复合储能装置符合车辆整体性能与制动能量回收的要求,体积、重量满足总体设计约束;匹配超级电容后,储能装置的瞬时功率能力大幅提升,可显著提高车辆的制动能力和制动能量回收率.According to the driving cycle of heavy off-road vehicles,the brake power and energy permutation is analyzed,and the performance requirement for the hybrid energy storage system（ HESS） is achieved based on the brake energy recovery rate and motor parameters.The parameter matching method for the HESS is proposed and by which the instance calculation for the hybrid propulsion system of 21 tons class vehicles is carried out,and the performance of the HESS with Li-ion cells and ultra capacitors is discussed too.The instance calculation and the test results indicate that the designed HESS can meet the requirement of the total performance of the HEV and the brake energy recovery,the volume and weight answer for the restriction of the top design of the HEV.The designed HESS with ultra capacitors can increase the transient power volume greatly and the brake performance and the brake energy recovery rate are enhanced remarkably.
