摘　　要：针对一款电电混合燃料电池电动汽车,从控制燃料电池系统输出功率出发,综合考虑燃料电池系统运行特性和蓄电池充放电特性,开发了一套电电混合燃料电池电动汽车在多种工况下的能量管理控制策略。控制策略在FCHEV联合仿真平台上进行了仿真验证,表明控制策略能够有效协调需求功率在燃料电池系统和蓄电池之间的分配,使燃料电池系统始终工作在高效率区域。通过与负载补偿型和负载跟随型控制策略的百公里氢耗量对比,该策略能够有效减低百公里氢耗。This paper is aimed at an electric vehicle hybrid fuel cell electric vehicle. Starting from controlling the output power of the fuel cell system,considering the operating characteristics of the fuel cell system and the charging and discharging characteristics of the power battery,the electric vehicle hybrid fuel cell electric vehicle is studied under various working conditions. The energy management control strategy and the control strategy are simulated and verified on the FCHEV co-simulation platform,which shows that the strategy can effectively coordinate the distribution of demand power between the fuel cell system and the power battery,so that the fuel cell system always works in the high efficiency region. Compared with the 100-kilometer hydrogen consumption of the load-compensated and load-following control strategies,this strategy can effectively reduce the hydrogen consumption per 100 km.
