Hydrogen Refueling Method for Heavy-duty FCV with Pressure Loss Compensation


Current hydrogen stations are using a constant dispenser pressure ramp rate method. When a flow rate increases for heavy duty vehicle, a large pressure loss occurs and it slows down refueling. This study developed a new method (cTPR method) that has the constant pressure ramp rate in the tank by compensating for the tube pressure loss without any feedback from the vehicle. A refueling simulation confirmed that a refueling was shortened − 49s with a lower ending gas temperature. Testing confirmed that the cTPR method can be realized simply by changing the control without any hardware modification.
