摘要
根据汽车起动系统电路模型,利用Matlab/Simulink平台搭建了汽车起动系统仿真模型--蓄电池单独供电和蓄电池与超级电容器直接并联组成复合电源供电。比较了两种供电状态下的蓄电池放电状态以及起动机输出功率。结果表明,加入了超级电容器的起动电源系统能大大降低蓄电池的放电倍率,起到保护蓄电池,延长其使用寿命的作用。同时,该仿真模型可用于汽车起动系统用复合电源的匹配设计。
Simulation model of automotive starting system is built on the Matlab/Simulink platform--battery-only supply and hybrid power supply which is composed of battery and ultra-capacitor directly in parallel, based on its circuit model. Discharge status of the battery and output power of the starter are compared under the two kinds of power supply. And the results show that discharge rate of the battery is decreased greatly with the latter starting power supply system to which ultra-capacitor is added, which has a good effect on protecting the battery and thus extends its service life. Meanwhile, the simulation model can also be used in the matching design of the hybrid power supply for automotive starting system.
