氢燃料-光伏电池汽车动力系统分层能量管理策略

汽车产业的热门趋势是新能源汽车,光伏电池汽车和燃料电池汽车的技术却未被开发,正是最好的发展方向。本文根据燃料电池和光伏电池的工作原理及输出特性,对其进行数学建模,选用双向全桥DC/DC变换器,作为系统控制的一部分,使用传统移相控制正向工作模式,并对其传输功率进行分析。利用matlab/simulink软件对上面的建立的数学模型进行建模仿真,建立出氢燃料-光伏电池汽车动力系统模型。分析研究氢燃料电池和光伏电池的能量控制理论,从而设计出系统级的协调控制与能量管理,即分层能量管理策略。

Design and Working Condition Analysis of Power System of Hydrogen Fuel-PlV Cell Vehicle

The hot trend of automobile industry is the technology of new energy vehicle.But the photovoltaic cell vehicle and fuel cell vehicle has not been developed,which is the best development direction.This paper models fuel cells and photovoltaic cells according to their working principle and output characteristics,then compares and analyzes various DC/DC converters,and finally selects bidirectional full-bridge DC/DC converters as part of system control.The forward working mode is controlled by traditional phase shift and its transmission power is analyzed.By using matlab/simulink software,the mathematical model is modeled and simulated,and the vehicle power system model of hydrogen fuel photovoltaic cell is established.The energy control theory of hydrogen fuel cell and photovoltaic cell is analyzed and studied,and the coordinated control and energy management,that is,hierarchical energy management strategy,is designed.
