Strong collaboration fuels growth! Yunneng Magic Cube and Weirui Energy have reached an intention to cooperate on a 600MWh project, marking the occasion with a strategic signing ceremony.
Published:2023-04-14
Recently, the 11th ESIE Energy Storage International Summit and Exhibition was held at the Shougang Convention Center in Beijing. During the event, Yuneng Magic Cube and Weirui Energy reached an agreement in principle to collaborate on a commercial and industrial distributed energy storage system project with a total capacity of 600 MWh, followed by a strategic partnership signing ceremony.

Weirui Energy is a leading enterprise in the field of new-energy vehicle components, affiliated with Geely Group. It is a cutting-edge technology company dedicated to the research, development, manufacturing, sales, and after-sales service of key new-energy vehicle systems, including power batteries, motor-electric control drive systems, charging systems, and energy-storage solutions. Rooted firmly in the "three electric" technologies of new energy—battery, motor, and electronic control—Weirui Energy has steadily expanded its business over more than a decade, building robust technical expertise along the way. Today, the company has broadened its reach into areas such as charging and energy storage, creating a comprehensive energy business ecosystem. As a result, Weirui Energy continues to deliver safe, efficient, and intelligent energy solutions to customers worldwide.
Cloud Energy Cube was founded by Dr. Zhang Jianxing, the lead drafter of the national standard for energy storage inverters and a member of the Ministry of Science and Technology's expert panel on "Energy Storage and Smart Grids." The Cloud Energy Cube technology team boasts over 20 years of technical expertise in the power industry, having spearheaded the development of more than ten national and industry standards, as well as participating in the Ministry of Science and Technology's prestigious 863 Program. To date, the company has secured over 20 national technology patents. With deep-rooted technological expertise and a forward-thinking R&D approach, Cloud Energy Cube has pioneered the seamless integration of cutting-edge innovations—such as the Power IoT, artificial intelligence, and edge cloud computing—with next-generation electric energy storage technologies and advanced control and protection systems for traditional power grids. This has enabled the company to innovatively introduce a groundbreaking "6S+EDR" nuclear-grade safety energy storage solution tailored specifically for the power sector.
Yuneng Magic Cube's next-generation "6S+EDR" nuclear-grade safety energy storage system introduces an innovative solution that redefines the traditional "PCS, BMS, and EMS" frameworks: The modular PCS features a string-based multi-branch design, enabling electrical and thermal isolation while significantly enhancing charging and discharging efficiency, boosting overall energy capacity, and improving system availability. Meanwhile, the open-style BMS incorporates plug-in temperature sensors and PACK-level fire suppression interlocks, effectively preventing battery cluster fires. It also leverages iterative data algorithms and remote OTA upgrades to precisely refine algorithm accuracy over time. Additionally, the flexible EMS implements system-level, partitioned safety management and dynamic, intelligent control mechanisms, helping to minimize the scope of potential incidents. To further elevate performance, the system integrates new subsystems—HCS, BWS, ASS, and EDR—which dramatically enhance the safety, intelligence, and grid compatibility of distributed energy storage products. Notably, Yuneng is the first globally to introduce the "intelligent black box" iEDR—a fault recording system tailored for energy storage power stations. This cutting-edge technology boasts advanced capabilities such as multi-source data collection, intelligent visual trace-back, real-time data alerts, and AI-driven analytics. By filling critical gaps in existing technologies, the iEDR provides comprehensive technical support, enabling energy storage stations to achieve robust fault recording, detailed accident analysis, and precise identification of responsibility during incidents.
The strategic partnership signing between Yuneng Magic Cube and Weirui Energy follows the successful delivery of the Zhejiang Ningbo Hangzhou Bay project, which marked a deep collaboration between the two companies. Moving forward, both parties will further deepen their resource integration and technological cooperation in the energy storage sector, leveraging their respective strengths to achieve complementary advantages, form a powerful alliance, and jointly drive growth. Together, they aim to deliver more competitive product equipment and system solutions to the global energy storage market.
