动力系统配置对燃料电池车经济性的影响分析

Powertrain Configuration Impacts on the Fuel Economy and Use-cost of Fuel Cell Vehicle

分别建立普通燃料电池车及Plug-in型燃料电池车混合动力系统仿真模型,结合各自混合动力系统特点,分别优选瞬时优化和恒温器能量管理控制策略,进而对不同混合动力系统配置燃料电池车的燃油经济性及使用成本展开研究分析。应用ADVISOR软件结合4种典型工况仿真分析表明,蓄电池初始电量为满电状态的Plug-in型燃料电池车,其燃油经济性和使用成本明显好于初始电量为亏电状态的Plug-in车型和普通燃料电池车;而蓄电池初始电量为亏电状态的Plug-in型燃料电池车,在不同工况下其燃油经济性与普通燃料电池车相比各有优劣但非常接近。

Researchers of this paper established hybrid powertrain simulation models of Plug-in fuel cell vehicle and fuel cell electrical vehicle. Furthermore, based on the systematic characteristics of hybrid powertrain, thermostat energy management strategy and instantaneous optimization energy management strategy were respectively employed for the two fuel cell vehicles to analyze fuel economy and use-cost. This research was conducted under typical driving cycles with ADVISOR. As the results show, the fully charged Plug-in fuel cell vehicle not only consumes less energy but saves more use-cost compared with both the discharged Plug-in fuel cell vehicle and fuel cell electrical vehicle. More significantly, the discharged Plug-in fuel cell vehicle and fuel cell electrical vehicle perform basically alike in the above-mentioned economy evaluation indicators while demonstrating particular strengths and weaknesses under different driving cycles.
