摘要
针对目前电动汽车由于蓄电池寿命和续航里程短导致其不能普及的现状,加入超级电容和DC/DC变换器构成复合储能系统,分析了汽车的运行状态,提出了一种改进的逻辑门限控制方法对复合储能系统进行能量控制。利用AVL CRUISE软件建立了整车模型,对能量控制策略进行了城市工况下的仿真验证。以48 V 5 k W的直流无刷电机及其控制器HPC300为载体,搭建了复合储能单元和其控制系统,仿真和实验结果表明该复合储能系统及其控制策略能够避免蓄电池的大电流输出和冲击,提高蓄电池的使用寿命和汽车的续航里程。
At present,the electric vehicles cannot be universal because of their short batteries life and driving range. An ultra-capacitor and a DC/DC converter were added to the pure electric vehicles constituting the compound energy storage system. Analyzing the operating state of vehicles,an improved logic threshold control method is proposed for controlling compound energy storage system. The whole vehicle model is established by using AVL CRUISE software,and the energy management strategy is simulated under urban condition. With the Brushless Direct Current Motor in 48 V and 5 k W and its controller HPC300 as the carrier,the compound energy storage system and its energy management system were built. The simulation and experimental results show that the compound energy storage system and its energy management strategy can avoid the input and output of high current of batteries,improve the life of batteries and the driving range of electric vehicles.
