Abstract
According to one aspect of the present invention, a hydrogen gas filling method includes receiving, from a vehicle equipped with a tank to be filled with hydrogen gas and powered by the hydrogen gas, a temperature of the tank before a start of filling; calculating a difference between a preset maximum temperature and the temperature of the tank; calculating a filling speed of the hydrogen gas depending on the difference; and filling the hydrogen gas from an accumulator in which the hydrogen gas is accumulated into the tank at the filling speed calculated via a measuring machine.
Claims9
A hydrogen gas filling method comprising:
- receiving, from a vehicle equipped with a tank to be filled with hydrogen gas and powered by the hydrogen gas, a temperature of the tank before a start of filling;
- calculating a difference between a preset maximum temperature and the temperature of the tank;
- calculating a filling speed of the hydrogen gas depending on the difference;
- and
- filling the hydrogen gas from an accumulator in which the hydrogen gas is accumulated into the tank at the filling speed calculated via a measuring machine.
A hydrogen gas filling device comprising:
- a reception circuit configured to receive, from a vehicle equipped with a tank to be filled with hydrogen gas and powered by the hydrogen gas, a temperature of the tank before a start of filling;
- a difference calculation circuit configured to calculate a difference between a preset maximum temperature and the temperature of the tank;
- a filling speed calculation circuit configured to calculate a filling speed of the hydrogen gas depending on the difference;
