5、d 2014-09 Fueling Protocol for Gaseous Hydrogen Powered Heavy Duty Vehicles RATIONALE As of publishing, there is not a published standard fueling protocol or adopted method for fueling hydrogen powered heavy duty transit buses and heavy duty vehicles that establishes the safety limits and performanc

6、e requirements for gaseous hydrogen fuel dispensers. As the market for hydrogen powered heavy duty transit buses expands, there is an industry interest to establish a standard fueling guideline for hydrogen powered heavy duty transit buses and vehicles. FOREWORD The intent of this document is to pro

7、vide guidance for performance oriented dispenser standards for safe fueling of hydrogen powered transit buses and heavy duty vehicles. 1. SCOPE The purpose of this document is to provide performance requirements for hydrogen dispensing systems used for fueling 35 MPa heavy duty hydrogen transit buse

8、s and vehicles (other pressures are optional). This document establishes the boundary conditions for safe heavy duty hydrogen surface vehicle fueling, such as safety limits and performance requirements for gaseous hydrogen fuel dispensers used to fuel hydrogen transit buses. For fueling light-duty v

9、ehicles SAE J2601 should be used. SAE J2601-2 is a performance based protocol document that also provides guidance to fueling system builders, manufacturers of gaseous hydrogen powered heavy duty transit buses, and operators of the hydrogen powered vehicle fleet(s). This fueling protocol is suitable

10、 for heavy duty vehicles with a combined vehicle CHSS capacity larger than 10 kilograms aiming to support all practical capacities of transit buses. It is non-prescriptive in how to achieve a full fill or 100% state of charge (SOC) in the vehicle tank storage system. This document is an independent

11、document from SAE J2601 “Fueling Protocols for Light Duty Gaseous Hydrogen Surface Vehicles” and should be used separately. The fueling limits shown in this document are harmonized with the fueling assumptions used for on-board fuel systems, as provided by gaseous hydrogen transit bus manufacturers.

SAE INTERNATIONAL J2601-2 Issued SEP2014 Page 7 of 13 4.7.4 Maximum Allowable Working Pressure (MAWP) The MAWP is the maximum gauge pressure of the working fluid (gas or liquid) to which a piece of process equipment or system is rated with consideration for ini

44、tiating fault management (see Figure A1 “Comparison of Pressure Vessel and Container Terminology” in Appendix A of J2579). 4.7.5 Nominal Working Pressure (NWP) The NWP is the gauge pressure that characterizes typical operation of a vehicle pressure vessel, container, or system. For compressed hydrog

45、en gas containers, the vessel pressure NWP is specified by the manufacturer, at a uniform gas temperature of 15 C and 100% SOC. NWP is sometimes known as Service Pressure (SP) or Pressure Class. 4.7.6 Pressure Class The pressure class will be defined by the protocols nominal working pressure. The cl

46、ass is denoted by the letter H followed by the nominal working pressure in MPa. For example, H35 is the pressure class for a hydrogen fueling protocol with a NWP of 35 MPa. 4.7.7 Pressure Drop The difference in pressure of gaseous hydrogen between two points in the fueling system used to fuel a vehi

47、cle. A high pressure drop leads to two effects that both yield a higher CHSS gas temperature at the end of fueling: First, the fueling is delayed. This consequently delays the temperature rise inside the CHSS and gives the gas less time to exchange heat with the internal liner surface. Secondly, mor

48、e Joule-Thomson heating is introduced into the CHSS because a higher station pressure is required to generate a given mass flow rate, and the enthalpy of hydrogen fuel gas increases with pressure. 4.7.8 Tank Pressure Pressure of hydrogen gas within each (single) vehicle storage tank 4.7.9 CHSS Press
