70 MPa大容量车载Ⅳ型储氢气瓶分级充氢测试技术研究
Research on staged hydrogen filling testing technology for large-capacity 70 MPa type Ⅳ on-board hydrogen storage cylinder
摘要
Abstract
To meet the hydrogen filling time requirements of the GB/T 42612-2023 standard for 70 MPa large-capacity type Ⅳon-board hydrogen storage cylinders,a study on staged hydrogen filling was conducted for a gas cylinder with a volume of 393 L.The staged filling process was numerically simulated,and the pressure switching thresholds were optimized using a differential evolution algorithm,yielding optimal switching points at 54.1 MPa and 84 MPa.To address the pressure fluctuation issue that tends to occur during high-pressure pneumatic valve switching,a pressure oscillation suppression method was proposed to improve system control stability.Experimental results show that the optimized strategy can reduce the time required to fill the 393 L gas cylinder to 87.5 MPa from 33 minutes 6 seconds in the synchronous hydrogen filling method to 6 minutes 24 seconds,meeting the standard requirement of 424.44 seconds.This method significantly can improve the refueling efficiency in hydrogen cycling tests for hydrogen storage cylinder,and holds great significance for promoting the industrialization of hydrogen fuel cell vehicles.关键词
