摘要
对电动汽车复合电源结构原理进行分析与介绍,依据超级电容和动力电池的实验特性建立车载复合电源的仿真模型,采用模糊控制理论建立了复合电源能量管理系统控制新策略,对Advisor中纯电动汽车模型进行二次开发,建立带复合电源的电动汽车整车模型,在不同道路驾驶循环工况下进行仿真,仿真结果表明:该模糊控制控制策略能够显著提高超级电容和锂电池的工作效率,发挥超级电容"削峰填谷"的作用,延长电池的使用寿命;在相同的条件下,车辆的动力性能和续使里程均得到提高。
The structure and operating principle of the compound power system in pure electric vehicle were introduced. The compound power model was established by the characteristics of ultracapacitor and battery, using fuzzy control theory to establish the energy manage ment control strategy for the compound power system, the pure electric model in Advisor was re--developed with the compound power sys- tem, simulation in the different circulation comtitions, and the simulation results indicate that the fuzzy control strategy which was designed in this paper can improve the working efficiency of the ultracapacitor and the lithium battery obviously. This system not only protected and expanded the working life of the battery, but also improved the dynamic performance of the vehicle in the same condtions.
