摘要： A gas-filling device (1) in which the design pressure of a pressure accumulator can be reduced while downsizing a compressor includes a compressor (4) and a pressure accumulator (5). In advance, a relationship between a filling pressure and a target flow rate is determined in accordance with the volume of a tank (3), the filling pressure is detected, and the target flow rate is determined. A flow rate of a gas to be supplied into the tank (3) is controlled according to the target flow rate. In a case where the target flow rate is equal to or less than a maximum discharge flow rate of the compressor (4), the gas is supplied to the tank (3) only from the compressor (4). In a case where the target flow rate is greater than the maximum discharge flow rate, the gas is supplied to the tank (3) from the compressor (4) and the pressure accumulator (5).

摘要： A gas supply apparatus includes; a compressor unit including a compression section compressing hydrogen gas and storing pressure accumulators with the compressed hydrogen gas and a drive portion including an electric motor as drive source and driving the compression section; and a control unit controlling the electric motor. The electric motor has output characteristics where rated torque can be maintained against rotational speed changes in a standard rotation region, rotation region at or below standard speed, and output torque decreases from the rated torque as electric motor rotational speed increases in an overspeed region, rotation region above the standard speed. The control unit performs, in at least part of a storage process where the compression section stores the pressure accumulators with the hydrogen gas until set pressure is reached, overspeed operation control for allowing driving of the electric motor in the overspeed region.
