Core equipment

1 gas cylinder testing environment warehouse

Three component testing environments仓

Allowable upper pressure limit of 105MPa

The high-pressure hydrogen circulation testing system consists of a gas cylinder testing environment chamber, three core component testing environment chambers, and a utility section. The testing chamber adopts explosion-proof design and is filled with nitrogen inside to resist physical explosion of the sample. Each testing chamber is independent of each other and can simultaneously test multiple hydrogen related components at different temperatures and pressures.

The temperature control range inside the warehouse is -45 ℃~+85 ℃, and the humidity can reach up to 98%. It can conduct high-pressure hydrogen cycle fatigue tests of 35MPa or 70MPa on hydrogen storage bottles and core components of hydrogen storage systems in low temperature, high temperature, and high humidity environments to evaluate the performance of rapid hydrogen charging and discharging in extreme temperature environments, including hydrogen storage bottles and supporting components.

At the same time, a penetration testing platform can be used to conduct penetration tests on gas cylinders, and analyze the permeability of gas cylinders through gas chromatographs to verify the ability of hydrogen storage systems to perform critical functions throughout the entire vehicle driving process, including product safety and reliability.

Cyclic testing under harsh and extreme conditions

Ensure the safety of hydrogen storage

The safety of hydrogen energy in the application process has always been a concern for people. From the perspective of practical engineering applications, as long as reasonable hydrogen energy application equipment and systems are used and operated according to regulations, the safety of hydrogen is guaranteed.

Hydrogen energy equipment belongs to the management category of special equipment and is subject to relevant regulations for special equipment. Before it is officially put into use, its safety and reliability performance need to be evaluated through professional testing methods and quality certification systems. It is necessary to use real high-pressure hydrogen or liquid hydrogen medium for type testing, simulate and assess its performance under extreme conditions and fault tolerance in case of misoperation or failure, and evaluate its performance and service life indicators to ensure batch production quality.
