The low durability and high cost of fuel cells and batteries are the main barriers of widely commercial usage of fuel cell hybrid electric vehicles. Energy management is one of the effective methods to increase the durability of power sources and the overall economy of the vehicle. The majority of existing studies focus only on fuel consumption. Therefore, an online applicable cost minimization strategy cooperating fuel cell and battery degradation is proposed to decrease the overall operating cost including hydrogen consumption cost and lifetime costs of fuel cell and battery. Two kinds of degradation models are both designed for fuel cell and battery respectively. Empirical degradation model and prognostic model are used to calculate the degradation cost and estimate the degradation performances of power sources along with aging. Creatively cooperating two kinds of models to precisely quantify the degradation rates of power sources under real automobile operating conditions is firstly studied. Validation under a typical driving cycle shows the effectiveness of the developed cost minimization strategy in increasing the economy of the vehicle. The effects of degradation and failure states of power sources, driving cycles and price evolution of hydrogen and power sources on the optimal cost results are also analyzed.

考虑电源退化的燃料电池混合动力汽车成本最小化策略

燃料电池和电池的低耐用性和高成本是燃料电池混合动力电动汽车广泛商业应用的主要障碍。能量管理是提高电源耐用性和车辆整体经济性的有效方法之一。大多数现有研究仅关注燃料消耗。因此，提出了一种协同燃料电池和电池退化的在线适用成本最小化策略，以降低整体运营成本，包括燃料电池和电池的氢消耗成本和寿命成本。分别为燃料电池和电池设计了两种退化模型。使用经验退化模型和预测模型计算退化成本并估计电源随老化的退化性能。首次研究了创造性地结合两种模型来精确量化实际汽车运行条件下电源的退化率。典型驾驶循环下的验证显示了所开发的成本最小化策略在提高车辆经济性方面的有效性。还分析了动力源的退化和故障状态、驱动周期和氢和动力源的价格演变对最优成本结果的影响。
