Energy matching of fuel cell vehicle based on pinch technology

为了提高燃料电池车的工作效率,对燃料电池和蓄电池的匹配问题进行研究。提出将夹点分析的方法运用到燃料电池和动力蓄电池的匹配研究中。以新欧洲驾驶周期(NEDC)循环工况为目标,计算出燃料电池的能量曲线,再通过夹点技术匹配燃料电池与蓄电池大小。将得到的参数在Advisor软件中仿真,验证夹点技术是否满足匹配要求。仿真结果表明,全工况下实际行驶曲线与工况曲线匹配良好,基于夹点技术的燃料电池与蓄电池匹配研究是可行的。

In order to improve the efficiency of fuel cell vehicles,the matching of fuel cells and batteries is studied.The pinch analysis method is applied to the matching research of fuel cell and power storage battery.Aiming at the NEDC cycle condition,the energy curve of fuel cell was calculated,and then the size of fuel cells and battery was matched by pinch technology.The parameters obtained were simulated in ADVISOR software to verify the correctness of the theoretical method.The simulation results show that most of the actual driving curves and working curves match well under most working conditions,which indicates that the matching research of fuel cell and battery based on pinch technology is feasible.
