【摘要】 为满足混合动力车辆动力性要求,并提高车辆的能量利用效率,根据动力单元与负载的能量关系及电池组充放电特性与SOC的关系,提出了一种基于电池组恒SOC和发动机燃油消耗优化控制的综合能量管理策略.对该策略进行实验验证的结果表明:电池组能保持在最佳工作状态,且车辆的燃油经济性提高了约8%.更多还原

【Abstract】 To meet the requirements in the performance of hybrid electric vehicle and improve its efficiency in energy utilization,the strategy of energy management is studied.According to the energy relationship between power units and loads,and based on the relationship between battery pack SOC and charging/discharging properties,management is integrated considering both fuel consumption optimal control for the engine and constant SOC control for the battery pack.It is validated by a series of experiments on a prototype vehicle.The results indicated that the battery pack could be kept in the best working conditions and the fuel economy was improved by about 8%.更多还原
