Abstract
A mobility includes a storage vessel, a power train configured to generate power using liquid hydrogen stored in the storage vessel, and a control device configured to downwardly adjust a target operating pressure of the storage vessel at a time of entering a refueling preparation mode, compare a supply pressure of the liquid hydrogen supplied to the power train with a target hydrogen supply pressure according to the target operating pressure, and limit the power of the power train in response to the supply pressure of the liquid hydrogen being less than the target hydrogen supply pressure.
Claims20
A mobility comprising:
- a storage vessel;
- a power train configured to generate power using liquid hydrogen stored in the storage vessel;
- and
- a control device configured to:
- downwardly adjust a target operating pressure of the storage vessel at a time of entering a refueling preparation mode;
- compare a supply pressure of the liquid hydrogen supplied to the power train with a target hydrogen supply pressure according to the target operating pressure;
- and
- limit the power of the power train in response to the supply pressure of the liquid hydrogen being less than the target hydrogen supply pressure.
A mobility comprising:
- a storage vessel;
- a power train configured to generate power using liquid hydrogen stored in the storage vessel;
- an auxiliary power train configured to assist the power train to supply the power;
- and
- a control device configured to:
- downwardly adjust a target operating pressure of the storage vessel at a time of entering a refueling preparation mode;
- determine a target hydrogen supply pressure according to the target operating pressure;
- and
- limit the power of the power train in response to a supply pressure of the liquid hydrogen supplied to the power train being less than the target hydrogen supply pressure and a state of charge (SOC) of the auxiliary power train being higher than an operating lower limit.
A method for controlling an operation of a mobility, the method comprising:
- downwardly adjusting a target operating pressure of a storage vessel in the mobility at a time of entering a refueling preparation mode;
- comparing a supply pressure of hydrogen supplied to a power train in the mobility with a target hydrogen supply pressure according to the target operating pressure;
- and
- limiting power of the power train in response to the supply pressure of the hydrogen being less than the target hydrogen supply pressure.
