摘　　要：为了避免混合动力客车运行过程中瞬时大电流和频繁充放电对蓄电池的伤害,提高其使用寿命,提出蓄电池-超级电容复合电源模型。基于逻辑门限能量分配控制策略,利用MATLAB/Simulink建立复合电源模型,通过二次开发将模型嵌入到ADVISOR仿真软件中,运用并联式混合动力客车模型进行混合动力客车整车仿真。经分析得出:超级电容起到了"削峰填谷"的作用,有效避免了大电流和大功率对蓄电池的伤害,达到提高电源系统性能的目的。In order to avoid the harm from the large current and the frequent charging and discharging in the operation process of the hybrid electric bus, to improve the life of the battery, this paper introduces composite energy storage system. Energy allocation control strategy based on logical threshold and MATLAB/Simulink is used to build the model of composite energy storage system, and the model is embedded into the simulation software-ADVISOR in the secondary development. The parallel hybrid electric bus model is used to simulate the hybrid bus, the simulation results are obtained. The results show that the ultra-capacitor plays the role of ＂peak clipping and valley filling＂, which effectively avoids the harm of high current and high power to battery, resulting in improving the performance of enengy storage system.
