Problems solved by technology

However, if hydrogen is supplied from a plurality of hydrogen suppliers to a tank with a large total capacity, the pressure in the tank will fluctuate locally, making it difficult to obtain an accurate hydrogen filling rate, and it is even difficult to fill hydrogen to an appropriate hydrogen filling rate.

Embodiment Construction

[0016] (First Embodiment) The hydrogen filling system 2 of the first embodiment will be described with reference to the drawings. exist figure 1 A block diagram of the hydrogen filling system 2 of the first embodiment is shown in FIG. The hydrogen filling system 2 includes a first hydrogen supplier 10 , a second hydrogen supplier 20 , and a fuel cell vehicle 30 including a first tank 31 and a second tank 32 . figure 1 It is a plan view showing the arrangement of the first hydrogen supplier 10 , the second hydrogen supplier 20 , and the fuel cell vehicle 30 . exist figure 1 , the dotted arrow line represents the signal line.

[0017] The fuel cell vehicle 30 includes a fuel cell 40 , an inverter 41 , and a motor 42 . The first tank 31 and the second tank 32 storing hydrogen and the fuel cell 40 are connected by a fuel pipe 37 , and the hydrogen in the first tank 31 and the second tank 32 is supplied to the fuel cell 40 through the fuel pipe 37 . The fuel pipe 37 is also co...

Abstract

A hydrogen filling system disclosed in the present specification is provided with: a first tank and a second tank which are configured so as to be capable of being filled with hydrogen and which communicate with each other; a first hydrogen supplier and a second hydrogen supplier configured to supply hydrogen to the first tank and the second tank; and a controller configured to control the first hydrogen supplier and the second hydrogen supplier. The controller estimates the hydrogen filling rate of the first tank and the second tank on the basis of a first internal temperature of the first tank, a second internal temperature of the second tank, a first pressure of the hydrogen gas supplied from the first hydrogen supplier, and a second pressure of the hydrogen gas supplied from the second hydrogen supplier. The controller is configured to stop the first hydrogen supplier and the second hydrogen supplier when the hydrogen filling rate reaches a predetermined threshold filling rate.

Description

technical field [0001] The technology disclosed in this specification relates to hydrogen filling systems. Background technique [0002] An example of a hydrogen filling system is disclosed in Japanese Patent Laid-Open No. 2010-286015. Hydrogen tanks are mounted on fuel cell vehicles. Hydrogen is supplied from the hydrogen supply device to the hydrogen tank. The amount of hydrogen in the hydrogen tank (hydrogen filling rate) is estimated from the temperature and pressure in the hydrogen tank. Hereinafter, in order to simplify the description, the hydrogen tank is simply referred to as a tank. [0003] When hydrogen is filled in a plurality of tanks connected to each other, the filling time becomes long. The filling time can be shortened by supplying hydrogen by connecting a plurality of hydrogen supply devices to the tank at the same time. As described above, the filling rate of hydrogen is obtained from the internal temperature and pressure of the tank. However, when ...
