摘　　要：混合动力汽车用蓄电池-超级电容组成的复合电源(HES)中超级电容工作状态对蓄电池寿命及HES高效工作至关重要。现有的HES能量分配控制策略普遍存在超级电容回收制动能量不充足,从而难以维持其适时放电的问题。针对现有的HES能量分配控制策略做了相应改进,在原有能量分配控制策略中加入了超级电容荷电状态(SOC)平衡约束条件。在汽车仿真软件Advisor上搭建了HES仿真模型,对其系统性能进行了仿真,结果显示了提出的能量分配控制策略能极大地提高超级电容放电时间,实验结果与仿真结果相吻合。这表明以超级电容SOC平衡为约束的复合电源控制思想的可实践性与优越性。The working state of the uhracapacitor in the hybrid energy storage （HES） system with the battery and the super capacitor is very important for the service life of the battery and the high efficiency of the HES.The power dis- tribution control strategy of the HES system is generally existing in the problem of the ultracapacitor recovery braking energy is not sufficient to maintain its timely discharge.The corresponding improvement is made on the distribution control strategy of HES, and a ultraeapacitor charge state （SOC） equilibrium constraint condition in the original energy distribution control strategy.The simulation model of the HES is built on the ADVISOR, and the system performance is simulated.The simulation results show that the proposed method can greatly improve the discharge time of the ultra-capacitor.The experimental results are in agreement with the simulation results.
