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.

Abstract: According to one aspect of the present invention, a method for diagnosing a failure of a flowmeter in a measuring machine, includes calculating a filling amount at an end of filling of the hydrogen gas into a tank from the measuring machine by using a pressure, a temperature, and a volume of the tank; and determining whether or not the flowmeter fails by using a plurality of error values between a metering filling amount at the end of filling measured using the flowmeter and a calculated filling amount at the end of filling calculated using the pressure, the temperature, and the volume of the tank, the plurality of error values being based on a plurality of past performance data stored in a storage device, and an error value at the end of filling of the hydrogen gas at a present time, and outputting a result.
