Abstract
A filling apparatus that does not significantly reduce a required pressure immediately after a start of hydrogen filling, and can reliably fill fuel cell vehicles and the like. The filling apparatus (100) includes a control unit (10), and the control unit (10) has a function of boosting pressure required from a hydrogen filling apparatus (100) to a rear facility (200) until initial pressure measurement is completed. The control unit (10) may have a function of determining whether or not communication filling is established, and when communication filling is established, setting a pressure higher than an internal pressure of a tank received from a vehicle side by a predetermined pressure (for example, 5 MPa) as a pressure required for the rear facility (200) at an initial stage of filling.
Claims10
A filling apparatus comprising a control unit, wherein said control unit is configured to:
- execute control for boosting pressure required from a rear supply facility in operative communication with the filling apparatus until a discharge pressure of the filling apparatus is equal to a prescribed initial pressure magnitude;
- and
- determine whether or not communication filling is established, and:
- when communication filling is established, to set the discharge pressure to be higher than an internal pressure of a tank received from a vehicle side by a predetermined amount;
- and
- when communication filling is not established, to set the discharge pressure to be equal to 30 to 60% of a maximum value.
A filling method comprising the steps of:
- determining whether or not a discharge pressure of a filling apparatus has met an initial prescribed pressure magnitude, and boosting the discharge pressure until the prescribed pressure magnitude is met;
- and
- determining whether or not communication filling is established, and:
- setting the discharge pressure to a magnitude higher than an internal pressure of a tank received from a vehicle side by a predetermined magnitude amount when communication filling is established;
- and
- setting the discharge pressure to be equal to 30 to 60% of a maximum value when communication filling is not established.
