Embodiment Construction

[0025] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the illustrated embodiment, a case is shown in which the gas to be filled is hydrogen, but the filling device according to the illustrated embodiment can also be applied to filling other gases. First, refer to figure 1 The outline of the hydrogenation plant according to the embodiment of the present invention is described. exist figure 1 , a hydrogenation device denoted by reference numeral 100 has a hydrogen supply pipe 1 and a control unit 10 . The upstream side of the hydrogen supply pipe 1 is connected to a hydrogen storage container 20 (such as a hydrogen bottle or a hydrogen storage tank) as a hydrogen supply source, and the downstream side of the hydrogen supply pipe 1 communicates with a filling hose 8 and a filling nozzle 9 when filling, The hydrogen supply pipe 1 is connected to a vehicle-side tank 31 of a vehicle 30 (fuel cell vehicle). A flow meter 2 , ...

Abstract

The aim of the invention is to provide a filling apparatus capable of using a single hydrogen storage container for as long as possible during hydrogen filling and maintaining opening degree of a flow rate adjusting valve within a predetermined range. A filling apparatus (100) according to the present invention includes a plurality of hydrogen storage containers (20: for example, hydrogen cylinders or hydrogen storage tanks), a pipe (1) that connects a filling hose (8) and the hydrogen storage containers (20), a flow rate adjusting valve (3: flow control valve) interposed in the pipe (1), and a control unit (10), and the control unit (10) has functions of adjusting a threshold value for switching the hydrogen storage container (20) communicating with the filling hose (8) to another hydrogen storage container (20) and adjusting valve opening of the flow rate adjusting valve (3).

Description

technical field [0001] The invention relates to a filling device for filling gas (such as hydrogen). Background technique [0002] In recent years, with the development and popularization of vehicles equipped with fuel cells (fuel cell vehicles: FCV), it has become important to increase the number of hydrogen stations (see, for example, Japanese Patent Publication No. 2000-166635). The hydrogen refueling station is equipped with a hydrogen refueling device, and the device adds hydrogen to the storage tank in the vehicle of the vehicle arriving at the hydrogen refueling station within a predetermined pressure range. [0003] In the prior art, when a fuel cell vehicle is refueled at a hydrogen station, a plurality of hydrogen storage containers (such as hydrogen cylinders or hydrogen storage tanks) with different maximum filling pressures are provided as back facilities, and the hydrogen storage containers are supplied to the refueling station. The hydrogen device supplies hy...
