摘　　要：作为电动汽车关键技术的车载复合电源系统已是研究热点。研究人员对复合电源系统的研究更多地关注整车能量管理研究与经济性。针对燃料电池(FC)+蓄电池(B)型复合电源进行瞬时功率研究,由于燃料电池不适于负担冲击性负载而提出瞬时功率抑制方案,即采用惯性环节对FC进行高频响应抑制使其仅响应低频负载,而对蓄电池不予限制。采用上下级管理解决方案,采用CAN通讯方式进行信息交互。通过进行功率分配实验与标准工况实验证明控制方案正确、可靠,此方案计算开销小有利于工程化实现。The hybrid power supply system vehicle has become hot topics as a key technology of electric vehicle （EV）. Researchers paid more attention to energy management and economy saving rather than real- time power allocation. Instantaneous power dispatching of every power subsystem is emphasized on Fuel Cell （FC） ＋ Battery （B） system. A inertia loop was introduced to suppress FCt s instantaneous power output since FC is not suitable for pulse load. An upper-lower layer management method was adopted and the two layers communicated by CAN. Finally, a series of experiments were carried on to prove correctness of the solution. The solution requires little computing cost and it is easy to engineering realization.
