Recently, ROBESTEC's independently developed "Ronghe Yinglong 5.0" 6.25MWh liquid cooled energy storage system, after rigorous design evaluation, product testing, and factory manufacturing capability assessment by Beijing Jianheng Certification Center (CGC), has officially obtained the GB/T 44026-2024 "Technical Specification for Prefabricated Cabin Lithium ion Battery Energy Storage System" certification, becoming one of the first system level products with the same capacity to obtain the national standard.

GB/T 44026-2024 is the first national technical standard specifically designed for "prefabricated cabin lithium-ion battery energy storage systems" in China. It specifies the appearance, size, protection level, equipment and components, functional requirements, and performance requirements of the system, and puts forward strict technical requirements for the prefabricated cabin body, cabin cables, and auxiliary systems.

This certification adopts a closed-loop review mode of "design evaluation+type testing+manufacturing capability evaluation+post certification supervision". CGC places risk control before the design phase to eliminate "defective design", and combines strict verification of manufacturing quality control capabilities and consistency with mass production, as well as continuous supervision after certification, to comprehensively ensure the safety and reliability of energy storage systems.

ROBESTEC · Yinglong 5.0 has obtained this certification, marking its leading advantages in core areas such as electrical safety, environmental adaptability, and thermal runaway risk prevention.

Leading efficiency, long-term gain

In a hundred megawatt level energy storage project, for every 1 percentage point increase in DC side efficiency, tens of millions of kilowatt hours of energy loss can be reduced cumulatively throughout the entire lifecycle. ROBESTEC · Yinglong 5.0 "achieves industry-leading DC side efficiency, reduces energy loss throughout the entire lifecycle, and significantly improves the return on investment for power plant owners. At the same time, a temperature rate SOH coupled adaptive charge discharge cutoff strategy is adopted to dynamically suppress the risk of lithium deposition, effectively delaying battery degradation and extending system life. Efficiency and lifespan are improved in parallel, with a significant increase in available electricity throughout the entire lifecycle, achieving a high balance between safety and economy.

Full scene adaptation, fearless of extreme environments

In response to technical pain points such as low air pressure and difficult heat dissipation in high-altitude areas, "ROBESTEC · Yinglong 5.0" has made deep breakthroughs in system design, which can meet the application scenarios at an altitude of 5000 meters and achieve stable operation in extremely complex geographical environments such as high altitude and severe cold. Meanwhile, with excellent thermal management technology, the system can operate within a wide temperature range of -30 ℃ to 50 ℃. Regardless of whether it is located in extreme cold or heat, the system can maintain optimal operating conditions, ensuring stable power supply in all-weather environments.

Crossing strict safety barriers and realizing long-term value. In the future, ROBESTEC will take this authoritative certification as the cornerstone and continue to output high safety, high reliability, and high economy green energy storage system solutions to the market, creating a solid moat for customer benefits with ultimate product strength.Editor/Yang Meiling
