Identify the factors affecting the accuracy of the consumption of hydrogen refueling station budget quotas at three levels:quotas preparation,construction and installation,and external environment,respectively.The common factors and key factors were extracted by analysis.The results show that all five metric factors significantly affect the accuracy of the budget quotas for hydrogen refueling stations.The degree of influence is F1(preparation method and basis)>F4(construction and installation technology)>F3(construction organization and management)>F2(preparation organization and members>F5(external environment).The speed of installation technology update,the matching of the preparation method with the measurement object,and the specification of the construction process are the key factors affecting the accuracy of consumption.Accordingly,we discuss the strategies to improve the accuracy of consumption were discussed:shorten the revision time of the quota and establish a long-term management mechanism;improve the matching degree between the preparation method and the measurement object;clarify the on-site construction specification of hydrogenation station and narrow the influence of construction deviation.
