  • Patent number: 10533708
    Abstract: The present invention is to properly manage life of an accumulator and extend the life of the accumulator. A gas supply system includes a control section, an acquiring section, a classifying section, and a judging section. The acquiring section acquires stress amplitude of accumulators from a pressure difference between first pressure on the gas storage side and second pressure on the gas lead-out side. The classifying section classifies the stress amplitude into a plurality of groups. The judging section divides the calculated acquirement number ni of the stress amplitude for each of the groups by the predetermined breaking cycle number Ni, and determines a fatigue degree ?ni/Ni. In a case where this value becomes a predetermined threshold value or more, the judging section judges that the accumulator comes to the end of the life.

  • Patent number: 10473268
    Abstract: 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.
