摘要
车载复合电源系统作为电动汽车的一项关键技术已成为研究热点。研究人员更多地关注整车能量管理研究与经济性。针对燃料电池FC(fuel cell,FC)+超级电容UC(ultra-capacitor,UC)复合电源构型进行瞬时功率研究,提出采用惯性环节对FC进行瞬时功率抑制以使其响应低频负载的控制方案。系统采用上下级的控制方案并采用CAN(controller area network,CAN)通讯方式进行交互。最后进行了功率分配实验与工况测实验证明控制方案正确。
As a key technology of electric vehicles （EV）, hybrid power system has become a hot research topic, especially concerning energy management and economy saving. After analyzing instantaneous power dispatching of the double power supply structure ＂fuel cell （FC） ＋ ultra capacitor （UC）＂, the paper proposes a control scheme to suppress FC＇ s instantaneous power output by adopting the inertia loop with the upper-lower layer management method and the two-layer interaction through CAN. A series of experiments have been carried out to prove correctness of the control scheme.
