Embodiment 1

[0044] This embodiment provides a temperature control method for filling hydrogen energy in a hydrogen refueling station, such as figure 1 shown, including steps:

[0045] S10. Obtain the hydrogen energy compressed by the compressor and cool the hydrogen energy for the first time;

[0046] S20, filling the hydrogen energy after the first cooling into the buffer bottle;

[0047] S30. Fill the first cooled hydrogen energy into the hydrogenation equipment through the buffer bottle.

[0048] The biggest potential risk of fast filling battery vehicles at hydrogen refueling stations is the temperature rise of vehicle-mounted gas cylinders during gas injection, especially for hydrogen energy vehicles with high pressure values, such as 70Mpa passenger cars. The main causes of temperature rise include: 1. The hydrogen gas passes through the compressor, and the temperature of the gas rises after compression; 2. The hydrogen gas has a "negative Joule Thomson effect", and the gas will a...

[0063] This embodiment provides a temperature control method for filling hydrogen energy in a hydrogen refueling station. In order to solve the heat generated by converting kinetic energy into heat energy when hydrogen is filled from a buffer bottle to a vehicle-mounted gas cylinder, this embodiment also includes steps S40, SA And step S50, by cooling the hydrogen energy for the second time, and simultaneously performing cascade and overlapping filling according to the small pressure difference, further controlling the temperature generated during the hydrogenation process so as to solve the temperature rise risk of hydrogen energy filling, including the steps :

[0064] S10. Obtain the hydrogen energy compressed by the compressor and cool the hydrogen energy for the first time;

[0065] S20, filling the hydrogen energy after the first cooling into the buffer bottle;

[0066] S30, filling the first cooled hydrogen energy into the hydrogenation equipment through the buffer bot...

Abstract

The invention provides a temperature control method and a temperature control system for hydrogen energy source filling of a hydrogen refueling station. The method comprises the following steps: S10,obtaining a hydrogen energy source compressed by a compressor and cooling the hydrogen energy source for the first time; S20, filling the hydrogen energy source cooled for the first time to a buffer bottle; and S30, filling the hydrogen energy source cooled for the first time to to-be-hydrogenated equipment through the buffer bottle. By conventionally cooling the hydrogen energy source compressedby the compressor and filling the hydrogen energy source to the to-be-hydrogenated equipment through the buffer bottle, a temperature rise problem generated in the hydrogen energy source filling process is solved by cooling the hydrogen energy source by gas for many times and reducing the pressure difference by way of gas pre-cooling and stepped and overlapped filling in the process of filling thehydrogen energy source to the to-be-hydrogenated equipment, so that the hydrogenation risk is reduced.

Description

technical field [0001] The invention relates to the technical field of new energy applications, in particular to a temperature control method and system for filling hydrogen energy in a hydrogen refueling station. Background technique [0002] With the development of economy and technology, the excessive development and use of traditional industrial energy, carbon dioxide emissions are increasing, causing global warming, and now countries all over the world are working hard to reduce carbon emissions. Hydrogen energy is recognized as a clean energy source and is emerging as a low-carbon and zero-carbon energy source. Fuel cell vehicles generally use hydrogen energy, but at present, the hydrogen refueling stations seen in China are waiting one by one when refueling. Multiple vehicles cannot be refueled at the same time, and the waiting time for vehicles is long. Longer, and the potential risk of sudden temperature rise is likely to occur during the rapid filling of hydrogen ...
