摘　　要：为进一步提高电动汽车的能量利用效率以改善其续驶里程,开发了一套电动汽车制动能量回收系统。系统结构简单,可靠性高,并具有机械制动备份功能。同时,考虑到电动汽车电动机和电池性能参数,开发了高效的再生制动控制策略,算法具有较强的移植性。采用硬件在环的方式对系统的控制效果和制动能量回收效率进行了仿真测试。结果表明,再生制动力和摩擦制动力可以很好地协调运作,同时有效地回收制动能量。最后,在燃料电池汽车上进行转鼓实验,很好地完成了Japan-1015循环工况,能量回收效率高达59.15%。In order to further improve the energy efficiency of electric vehicles,thus to improve the driving range economy,a braking energy recovery system for electric vehicles with simple structure,high reliability and fail-safe function was developed.Meanwhile,considering performance parameters of motor and battery,the efficient regenerative braking control strategy with strong portability was developed.Based on the proposed system and control strategy,hardware-in-loop tests were accomplished.Test results showed that friction braking force and regenerative braking force could be well integrated and braking energy recovery efficiency was high.Finally,experimental data of a FCV on CYC Japan-1015 proved the performance and feasibility of the proposed system.Braking energy recovery efficiency reached to 59.15%.
