Claim 9:
10. A method for hydrogen dispensing, comprising:
providing at least one sensor arranged and positioned to collect measurement data for filling a fuel tank of a vehicle with hydrogen fuel;
providing a computer device communicatively connected to the at least one sensor, the computer device having a processor connected to a non-transitory computer readable medium;
providing a display device communicatively connected to the computer device to display estimated time remaining indicia to indicate an estimated time remaining to fill the fuel tank based on an estimated time remaining determined by the computer device and update the displayed estimated time remaining indicia as dispensing of hydrogen fuel to the fuel tank occurs based on an updated estimated time remaining determined by the computer device;
the computer device configured to determine the estimated time remaining via an estimated time remaining process defined by code stored in the non-transitory computer readable medium based on sensor data received from the at least one sensor; and
the computer device configured to determine the updated estimated time remaining based on the sensor data received from the at least one sensor while the fuel tank is being filled with the hydrogen fuel via an updated estimated time remaining process defined by code stored in the non-transitory computer readable medium;
wherein at least one of: the estimated time remaining process also comprises adding time to the estimated time remaining to account for performance of leak checks and/or bank switching; and the updated estimated time remaining process also comprises adding time to the updated estimated time remaining to account for performance of leak checks and/or bank switching; and
wherein the adding of time to the estimated time remaining to account for the performance of leak checks comprises: multiplying a pre-determined number of leak checks to be performed during the filling of the fuel tank by a pre-selected leak check performance factor value.
