As China's hydrogen energy industry accelerates toward a new stage of large-scale and commercialized development, the insufficient reliability of hydrogen energy products in vehicle operation has gradually become a key bottleneck constraining the industry's quality improvement and upgrading. To address the industry's testing challenges and strengthen product safety assurance, the National Hydrogen Energy Power Quality Inspection and Detection Center of CAERI completed a significant capability upgrade. The newly built 0–400kW full-power-range hydrogen-involved loaded tri-combined vibration testing platform was officially completed and fully launched for commercial services. This equipment successfully filled the technological gap in China's large power hydrogen-involved multi-physics field coupling testing, building core technical support for the high-quality development of hydrogen energy vehicles and hydrogen energy equipment in China.
For a long time, the industry's traditional single-stress testing mode had obvious limitations, capable of completing product performance verification only under a single environment, unable to reproduce the complex scenarios of overlapping temperature, humidity, vibration, and loaded operating conditions during actual vehicle operation, and unable to accurately replicate the composite failure mechanisms of equipment. As a result, many products that met laboratory standards exposed various reliability issues after actual vehicle deployment. Targeting this industry pain point, CAERI leveraged its forward-looking technology layout and independent R&D capabilities to break through the performance boundaries of traditional testing equipment. Through self-developed proprietary measurement and control systems and customized hardware architecture, CAERI created an industry-leading hydrogen-involved loaded tri-combined vibration testing platform, achieving comprehensive breakthroughs in integrated testing performance.
According to the introduction, the testing platform features four core technological advantages, adapting to testing requirements of all categories of large power hydrogen energy equipment. In terms of power coverage, the equipment supports 0–400kW continuous loaded operation, fully adapting to testing scenarios of mainstream large power hydrogen energy equipment such as fuel cell heavy trucks, passenger vehicles, and hydrogen energy construction machinery, while reserving 3 to 5 years of technological upgrade space to accommodate future industry trends in large power product iteration. In terms of verification dimensions, it can achieve full-coverage reliability verification of core parts and subsystems including fuel cell stacks, complete engine systems, air compressors, hydrogen circulation pumps, and DCDC, accomplishing multi-level, full-dimension testing and verification.
In terms of environmental simulation, the platform can simultaneously superimpose three types of environmental stresses: an ultra-wide temperature range from -40°C to 90°C, full-range humidity from 10% to 95% RH, and broadband vibration from 5 to 2,000 Hz, highly reproducing various extreme and complex service conditions. It also supports real operating condition loading under vibration environments, including rated power, peak power, dynamic variable load, and start-stop cycles, replicating the actual operating state of hydrogen energy equipment after vehicle installation on a 1:1 basis, significantly improving the accuracy and reference value of test data. Currently, the platform has completed comprehensive performance calibration and safety evaluation, possessing mature commercial service capabilities. It can customize exclusive testing solutions based on enterprise R&D requirements, precisely matching the reliability verification needs of various hydrogen energy products.
The implementation of this large power hydrogen-involved testing capability will comprehensively empower hydrogen energy industry development from three dimensions: safety prevention and control, product iteration, and industry standardization. On one hand, by simulating complex road conditions and dynamic loaded superimposed operating conditions, it can proactively identify hidden fault risks such as stack seal fatigue, pipeline joint loosening, and wiring harness contact anomalies, avoiding major safety risks such as hydrogen leakage and power interruption at the source, and proactively building a solid safety operation defense line for hydrogen energy equipment. On the other hand, leveraging precise and detailed test data, it helps enterprises optimize product structures and production processes, effectively shortening product finalization cycles, reducing R&D trial-and-error costs, and accelerating the market-oriented iteration of hydrogen energy products.
In addition, the massive real-test data accumulated by the platform will provide core data support for the formulation of industry standards for hydrogen-involved loaded vibration testing in China. CAERI will leverage the advantages of its national-level detection platform to take the lead in improving industry testing specifications and technical standards, unifying industry testing criteria, and guiding the standardized, orderly, and high-quality development of the hydrogen energy industry.
As a national-level core platform for hydrogen energy detection, CAERI has continuously built a "material-component-system-vehicle" full-chain, independently controllable hydrogen energy inspection and detection system. Since its commissioning in 2022, the center has successively completed multiple pioneering testing projects, including China's first extreme fire test on a fuel cell vehicle-mounted hydrogen system, fuel cell stack hydrogen deflagration test, and solid-state hydrogen storage system extreme fire test, filling multiple industry technological gaps. The implementation of this 400kW large power tri-combined vibration testing capability further improved the full-chain hydrogen energy detection service matrix.
In the future, CAERI will continue to leverage the technological leadership advantages of its national-level platform, continuously iterate and upgrade hydrogen energy detection technologies and service capabilities, address industry testing shortcomings, comprehensively safeguard the safety and reliability of hydrogen energy products, and escort the large-scale, high-quality development of China's hydrogen energy industry.
