Embodiment 1

[0046] figure 1 It is an example of a structural diagram showing the structure of the hydrogen fuel supply system of the hydrogen station in Embodiment 1. exist figure 1 Among them, the hydrogen fuel supply system 500 is arranged in the hydrogen station 102 . The hydrogen fuel supply system 500 includes a multistage accumulator 101 , a distributor (Japanese: dispensa) 30 , a compressor 40 , and a control circuit 100 . The multi-stage accumulator 101 includes a plurality of accumulators 10 , 12 , 14 in which the use lower limit pressure is set in multiple stages. exist figure 1 In the example shown, the multi-stage accumulator 101 includes three accumulators 10, 12, 14. exist figure 1 In the example of , the accumulator 10 functions as a first storage bank (Japanese: bank) whose lower limit pressure is low. The accumulator 12 functions as a second storage tank whose use lower limit pressure is in the middle. The accumulator 14 functions as a third reservoir having a ...

Embodiment 2

[0125] In Embodiment 1, the case of using a correlation table defining the lower limit threshold value of the flow rate corresponding to the temperature of the supplied hydrogen fuel, the external temperature, and the pressure of the fuel tank 202 of the FCV vehicle 200 was described, but the correlation table is not limited to this. In Embodiment 2, a case of using a simpler correlation table than in Embodiment 1 will be described. The structure and structure of the hydrogen fuel supply system of the hydrogen station in Embodiment 2 figure 1 same. In addition, the flow chart and the flow chart showing the main steps of the filling method of hydrogen fuel in Embodiment 2 and Figure 8 same. The content other than the correlation table is the same as that of Embodiment 1.

[0126] Figure 11 It is a figure which shows an example of the correlation table in Embodiment 2. exist Figure 11 In part A' of , an example of the correlation table when the first bank is used for ...

Abstract

A hydrogen fuel filling system according to an embodiment of the present invention is characterized by being provided with: a first flow channel through passes which hydrogen fuel supplied from a pressure accumulator in which the hydrogen fuel is accumulated; a second flow channel which is disposed in parallel with the first flow channel and through which the hydrogen fuel supplied from the pressure accumulator passes; a switching valve for selectively switching the flow channel from one of the first and second flow channels to the other thereof, or switching the flow channel between one and both of the first and second flow channels; and a control circuit for controlling the opening and closing of the switching valve; a fuel cell automobile using hydrogen fuel as a power source being filled with the hydrogen fuel while the flow channels are switched by the switching valve during supplying from the pressure accumulator.

Description

technical field [0001] This application is an application claiming priority based on JP2018-050037 (application number) filed in Japan on March 16, 2018. The content described in JP2018-050037 is incorporated in this application. [0002] The present invention relates to a hydrogen fuel filling system and a hydrogen fuel filling method, for example, to a hydrogen filling system and method for ordinary vehicles using hydrogen as fuel to fill hydrogen at a hydrogen station. Background technique [0003] As a fuel for automobiles, in addition to fuel oil represented by gasoline that has attracted attention in the past, hydrogen fuel has also attracted attention as a clean energy source in recent years. Accompanied by this, the development of fuel cell vehicles (FCV: Fuel Cell Vehicle) using hydrogen fuel as a power source has been continuously promoted. In order to popularize the above-mentioned fuel cell vehicles (FCV), it is necessary to expand hydrogen stations capable of ...
