Study on comprehensive evaluation of 35 MPa/70 MPa hydrogen dispenser refueling performance

通过分析35 MPa/70 MPa加氢机工作模式和比较加注性能的优劣,结合氢燃料电池车用户体验和车载储氢瓶的限制条件,提出了35 MPa/70 MPa加氢机加注性能的综合评价指标,定义了加氢机加注性能指数。继而分别开展了35 MPa、70 MPa加氢机对乘用车和物流车的加注试验,并用此指标衡量了两加氢机的加注性能,比较了35 MPa、70 MPa加氢机的加注性能。该指标直观可靠,简单易算,且能反映加氢机的综合加注性能。成果可应用于35 MPa/70 MPa加氢机的实际工作性能评价,为35 MPa/70 MPa加氢机长周期安全可靠运行提供评价依据。

This study analyzes the working model and refueling performance of a 35 MPa/70 MPa hydrogen dispenser and assesses the user experience of hydrogen fuel cell vehicles and the restriction conditions of on-board hydrogen storage tanks. Based on the results, a universal evaluation index of the refueling performance of a hydrogen dispenser is proposed. A refueling test was conducted on a 35 MPa/70 MPa hydrogen dispenser for passenger and logistics vehicles, and the refueling performance of the dispenser was measured by the evaluation index. The index is direct and reliable, simple and easy to calculate, and comprehensively reflects the refueling performance of the hydrogen dispenser. The index is applicable to actual performance evaluations of 35 MPa/70 MPa hydrogen dispensers and provides technical and theoretical support for ensuring their reliable operation.
