Japanese Patent JP7033277
Kind Code:
B2
Abstract:
To provide a calibration method of hydrogen fueling apparatuses dispensing with the following processes: causing a fuel cell vehicle to travel and wait until an in-vehicle tank becomes empty; and preparing a plurality of (for example, four) fuel cell vehicles (FCV).SOLUTION: A calibration method of a hydrogen fueling apparatus (100) of the present invention includes the steps of: connecting a fueling nozzle (2) of the hydrogen fueling apparatus (100) to be calibrated, to a receptacle (5) of a calibration device (10) including a fueling tank (4); and fueling hydrogen gas to the fueling tank (4) via a hydrogen flowmeter (3: a reference flowmeter). While the pressure and temperature in the fueling tank (4) are transmitted via signal transmission means (7), the receptacle (5) and the fueling nozzle (2) to the hydrogen fueling apparatus (100), the hydrogen gas is fueled from the hydrogen fueling apparatus (100) via the fueling nozzle (2) and the receptacle (5) to the fueling tank (4), while measuring the hydrogen gas flow rate by the reference flow meter (3).SELECTED DRAWING: Figure 1
