Apparatus and method for hydrogen fuel dispensing

A method of generating a display of time remaining indicia for a display at a dispenser of a fueling station for filling a fuel tank of a vehicle with hydrogen fuel, the method comprising:

• determining an initial estimated time remaining based on sensor data received from one or more sensors for generation of initial time remaining indicia for display at the dispenser, the initial estimated time remaining being determined based on at least one of:
• (a) End Pressure=0.1227*(−0.0266*(35−StartP){circumflex over ( )}2+2.5891*(35−StartP)+32.313, where “StartP” is a starting pressure in Mega Pascal (MPa) and End Pressure is an end pressure in MPa;
• (b) End Pressure=0.2409*(−0.0149*(70−StartP){circumflex over ( )}2+2.0222*(70−StartP)+64.435, where “StartP” is the starting pressure in MPa and End Pressure is the end pressure in MPa;
• (c) Time remaining=End Pressure−Current Pressure/Ramp Rate, where EndPressure is the fuel tank end pressure in MPa and the Ramp Rate is an increase in pressure measured at the fuel tank in MPa/min;
• (d) Pressure Remaining=End Pressure−Current Pressure;
• (e) Mass Remaining=Amount of mass available to be fed to the fuel tank−Mass of the hydrogen fuel dispensed to the fuel tank;
• and
• (f) determining an amount of hydrogen fuel to be fed to the fuel tank to fill the fuel tank and dividing the determined amount of hydrogen fuel to be fed to the fuel tank to fill the fuel tank by a dispenser controlled flow rate value.

A non-transitory computer readable medium having code stored thereon that defines a method that is performed by a computer device when a processor of the computer device runs the code, the method comprising:

• determining an estimated time remaining to fill a vehicle fuel tank with hydrogen fuel based on sensor data received from at least one sensor;
• communicating with a display device at a dispenser to generate estimated time remaining indicia to display at the display device based on the determined estimated time remaining to fill the vehicle fuel tank with the hydrogen fuel;
• determining an updated estimated time remaining to fill the vehicle fuel tank with hydrogen fuel based on sensor data received from the at least one sensor while the vehicle fuel tank is being filled with fuel;
• and
• communicating with the display device at the dispenser to generate updated estimated time remaining indicia to display at the display device based on the determined updated estimated time remaining to fill the vehicle with the hydrogen fuel.
