| 摘 要： | 由于混合动力车辆中的电系统结构复杂,多个部件存在多向的电能量流动耦合关系,同时在多向的电能量流动过程中需要克服不同的交直流阻抗,所以需要研究电能量流表征和优化管理方法.在建立电能量流复杂耦合系统模型的基础上,通过研究在复杂载荷条件下单电池荷电状态变化规律,成组电池电能损耗稳态、瞬态变化规律,辅助能量单元效率变化特性和负载系统在不同模式下的稳态、瞬态能耗规律,提出了电能量优化的管理方法.硬件在环试验结果表明,该方法在一定程度上提高了电池组的寿命,也提高了车辆的燃油经济性.

| Abstract: | Electric power flow is important power flow in hybrid vehicle. The coupling relations of multi- direction electric power flow exist among multi-components as various AC impedances and DC resistances. Based on the complicated coupling system model of electric power flow, rules of SOC, static and dynamic wastage, efficiency under various environment and complex load conditions were researched. The optimal energy management strategy of electric power flow was proposed to improve efficiency and economy of hybrid vehicle. |
