STUDY ON FAST FILLING OF HIGH PRESSURE HYDROGEN FOR FUEL CELL VEHICLES

根据作者所在课题组前期开发的燃料电池汽车高压H2快速加注策略,对储氢瓶H2加注的过程和方式进行研究。首先利用深圳大运会加氢站设备进行观光车用28 LⅢ型车载储氢瓶多级加注实验研究;然后建立储氢瓶的数值模型,用实验数据验证模型准确性后,利用该模型模拟极端条件下根据加注策略进行加注的加注情况。实验和仿真的温升、加注时间和SOC结果均满足SAE TIR J2601标准的要求。

This paper studied on the process and pattern about hydrogen fast filling based on the refueling strategy which the author＇ s research group developed earlier. The experiment of hydrogen cascade filling was conducted at Shenzhen Universiade Hydrogen Refueling Station. And a numerical model of the type II1 hydrogen tank of 28 L was built and verified by the comparison between the simulation result and the test. The model was also used to simulate the refueling process on extreme conditions with this strategy. The conclusion showed that the temperature, the filling time, and SOC all meet the requirement of the standard SAE TIR J2601.This study will provide theoretical guidance for the control strategy during the fast filling procedure of the fuel cell vehicles.
