Abstract: A hydrogen refueling station evaluation device includes a socket that is supplied with hydrogen, a hydrogen tank that stores the hydrogen supplied through the socket, and a discharge pipeline that discharges hydrogen from the hydrogen tank to the atmosphere. A discharge valve adjusts open and closed states of the discharge pipeline. A tank protection valve achieves a state in which the socket and the hydrogen tank are connected to each other, a state in which the socket and the discharge pipeline are connected to each other and the hydrogen tank is closed, and a state in which all of the socket, the hydrogen tank, and the discharge pipe are connected to one another. A gas supplier supplies an inert gas to the socket and a controller operates the tank protection valve, the discharge valve, and the gas supplier.

Abstract: A system for evaluating filling performance of hydrogen storages having various capacities uses a plurality of nozzles, a plurality of receptacles, and a plurality of hydrogen storages, and includes discharging hydrogen filled in one hydrogen storage while filling another hydrogen storage with hydrogen. Evaluation of filling performance may be performed in a back-to-back manner such that hydrogen is introduced into one of the plurality of hydrogen storages and discharged from another of the hydrogen storages. The plurality of hydrogen storages have various capacities, and introduction of hydrogen into the plurality of hydrogen storages is controlled according to a combination of hydrogen storages that corresponds to an evaluation target capacity, such that filling performance evaluation for various capacities is possible.
