An important part of the work of the Society of Automotive Engineers (SAE) revolves around establishing standards for automotive design
. These standards help engineers design in compatibility so that vehicles can co-exist in the automotive eco-system. Last year, SAE established the J1772 standard for electric vehicle charging connectors
. Now, as engineers prepare to gather for the annual SAE World Congress in Detroit next week, SAE has published J2601, a protocol for fueling vehicles with gaseous hydrogen
The standard defines safety and performance requirements for hydrogen dispensers. This includes factors like maximum temperature at the nozzle, fill rates and pressure rise rates. The standard applies to both 350 BAR and 700 BAR filling systems. Standards like this don't define the design of the filling system. Instead it provides a guide so engineers can develop control systems uniformly.
