A new hydrogen fueling protocol called MC Multi Map (MC-MM) was developed to reduce hydrogen station operating costs. With the MC-MM, the number of fueling control maps has increased from before and precise switching among them according to circumstances has achieved relaxation of precooling temperatures. Fueling control maps for hydrogen stations are created in accordance with Society of Automotive Engineers (SAE) protocol, but with the MC-MM, greater accuracy of mapping is necessary, so steps were taken to revise the boundary conditions prescribed by the SAE. The creation of fueling control maps for a hydrogen fueling protocol used to require outsourcing of map analysis. However, the National Renewable Energy Laboratory research institute in the US has made a hydrogen fueling simulation called H2FillS publicly available on the Web so that analysis of fueling control maps can now be performed by anyone.
