摘要
以某款燃料电池商用车为研究对象,研究了能量源混合度对车辆燃油经济性的影响。针对燃料电池、动力电池的车辆构型,建立了车辆驱动系统模型。引入了基于动态规划的能量管理策略,搭建了整车控制框架。引入了混合度理论,研究了车辆在不同混合度下的燃油经济性。仿真结果显示:在WHVC工况下,车辆的混合度达到0.73时其对应燃油经济性最高。
In this paper,the influence of hybridization on vehicle fuel economy was studied for the propulsion system of a fuel cell commercial vehicle.Firstly,the fuel-cell/battery hybrid propulsion system model is established according to the vehicle configuration.Secondly,the energy management strategy based on dynamic programming is introduced to build the control framework.Finally,the concept of hybridization for fuel cell vehicle is introduced to study the fuel economy of vehicles under different hybridization.The simulation results show that the fuel economy may be optimal when the hybridization reaches to 0.73 under the drive cycle of WHVC.
