Problems solved by technology

[0010] However, when the fuel cell vehicle is driven to the pressure in the on-board tank to a predetermined initial pressure (until it becomes so-called "empty") ( Figure 8 ), the time for interrupting the calibration and waiting for a long time, the calibration of a hydrogen filling device will take a lot of time
[0011] On the other hand, if multiple (for example, 4) fuel electric vehicles ( Figure 9 case), the preparation of the correction operation requires a lot of labor and cost

Embodiment Construction

[0062] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0063] First, refer to Figure 1 ~ Figure 4 A first embodiment of the present invention will be described.

[0064] exist figure 1 Among them, the calibration device represented by reference numeral 100 as a whole includes: a measuring case 1, a filling tank 2 disposed in the measuring case 1, a scale 3 for measuring the weight of the measuring case 1, and a housing for the measuring case 1 and the scale 3. (weight measuring device) main body case 10. Furthermore, filling tank 2 is placed on the bottom surface of measurement case 1 via pedestal 8 .

[0065] The weight of the hydrogen gas supplied and filled into the filling tank 2 is determined by measuring the weight of the measuring case 1 before and after filling the hydrogen gas with a scale 3 , and is determined from the difference in weight before and after the filling of the hydrogen gas.

[0066] The main b...

Abstract

Provided is a method for calibrating a hydrogen filling device which does not require a fuel cell vehicle to travel until an on-vehicle tank becomes empty and idle or require a plurality of (for example, four) fuel cell vehicles. The method for calibrating the hydrogen filling device of the present invention comprises a step of connecting the filling nozzle (41) of the hydrogen filling device (40)to be calibrated to a receptacle (6) of a calibration device (100) having a filling tank (2), a measuring housing (1) incorporating the filling tank (2), and a weight measuring device (3: balance) for measuring the weight of a measuring housing (1); a step of filling the filling tank (2) with a hydrogen gas; a step of determining the amount of hydrogen filling the filling tank (2) based on the difference between the weight of the measuring housing (1) before hydrogen filling and the weight of the measuring housing (1) after hydrogen filling; and a step of releasing the hydrogen filling the filling tank (2) (out of the calibration device) via an exhaust gas mechanism (11) provided in the calibration device (10).

Description

technical field [0001] The present invention relates to a hydrogen filling device used in a hydrogen station as a facility for filling hydrogen into a hydrogen car and the like, and relates to a technique for correcting the hydrogen filling device. Background technique [0002] In recent years, with the development and popularization of vehicles equipped with fuel cells (fuel cell vehicles: FCV), increasing the installation places of hydrogen stations (for example, refer to Patent Document 1) has attracted attention. [0003] A hydrogen filling device is installed at the hydrogen station, and the on-board tank of the vehicle arriving at the hydrogen station is filled with hydrogen at a predetermined pressure by the hydrogen filling device. In addition, in order to safely and accurately fill the vehicle-mounted tank with hydrogen, the work of calibrating the hydrogen filling device is regularly performed. [0004] This calibration work is performed, for example, using a cali...
