【摘要】 动力电池是plug-in混合电动汽车的核心部件,其性能直接影响着混合动力汽车性能的好坏。动力电池的寿命及性能受到多方面的影响,其中充、放电程度对其性能和寿命影响最大。在考虑电池寿命的原则上,本文提出一种模糊转矩实时修正的控制方法,该控制策略在考虑燃油经济性和排放最优的基础上,有效地控制了电池SOC的波动范围。仿真实例也表明,该种控制策略符合PHEV的工程化要求。更多还原

【Abstract】 Power cells are the core components of Hybrid electric vehicle,which directly affect on the performance of hybrid electric vehicle.The lives and performances of energy storages are influenced by various aspects,Especially the level of charge and discharge.As considering battery life on the base we introduce a new fuzzy contorl method of torque real-time modification.On the basis of considering fuel economy and emissions,this strategy can make the soc of battery fluctuated in a narrow area.And the example also shows that the strategy is suitable for the engneering needs of PHEV.更多还原
