基于超级电容器的太阳能汽车储能系统研究

摘要

针对太阳能汽车在启动时需要蓄电池提供瞬时大电流,制动时会使蓄电池承受大电流冲击,导致蓄电池寿命严重缩短这一问题,提出一种基于超级电容器的新型储能系统,并通过模糊控制使超级电容器与蓄电池协调工作.本设计在MATLAB平台上搭建了基于超级电容器的太阳能电动汽车混合储能系统的模型,进行相关的仿真实验,实验结果表明混合储能方式可以提高汽车启动速度,减少对蓄电池造成的损害.%The new energy storage system is proposed for the problem that the severe shortening of battery life, what caused by the instantaneous current must be provided in the start of the solar vehicle and the impact of the high current must be born in the braking by battery, and a new type of hybrid energy storage system based on super capacitor is proposed. The model is built and run in the MATLAB, the simulation results show that the start speed of the car is improved and the damage for the battery is reduced.
