Abstract

A hydrogen gas filling device includes a reception circuit, a difference calculation circuit, a filling speed calculation circuit, an accumulator, and a filing machine. The reception circuit is configured to receive, from a vehicle equipped with a tank to be filled with hydrogen gas and powered by the hydrogen gas, a value of a parameter of the vehicle. The difference calculation circuit is configured to calculate a difference between a predetermined value and the value of the parameter received from the vehicle. The filling speed calculation circuit is configured to calculate a filling speed of the hydrogen gas depending on the difference. The accumulator is configured to accumulate hydrogen gas. The filling machine is configured to fill the tank with the hydrogen gas from the accumulator at the calculated filling speed. A hydrogen gas filling method includes the operations noted above.

Claims16

Dependent claims

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, temperatures of the of the vehicle during the process of filling the tank with the hydrogen gas;
a difference calculation circuit configured to calculate a plurality of differences at different times during the process of filling the tank with the hydrogen gas, the differences being differences between a preset and unchanging temperature and the temperature of the tank measured at different times during the process of filling the tank with hydrogen gas, the preset and unchanging temperature being the maximum allowable temperature of the tank;
a filling speed calculation circuit configured to calculate a plurality of filling speeds of the hydrogen gas, each depending on a different calculated difference between the preset and unchanging temperature and the temperature of the tank measured at a different time during the process of filling the tank with hydrogen gas;
an accumulator configured to accumulate hydrogen gas;
and
a filling machine configured to fill the tank with the hydrogen gas from the accumulator at the calculated filling speeds.
