The next-generation compact distributed liquid-cooled energy storage cabinet, jointly developed by Yunneng Magic Cube and Zhejiang Wuyun Energy, has passed national-level testing and certification.
Published:2024-01-04
Recently, the next-generation compact 100kW/215kWh distributed liquid-cooled energy storage cabinet—jointly developed by Yunneng Magic Cube and Zhejiang Wuyun Energy—has successfully passed inspection and certification by STIEE, a nationally recognized testing organization.
In addition to rigorously testing the energy storage cabinet's active power regulation capability, reactive power regulation, charge-discharge switching time, and rated energy—key metrics for this STIEE inspection—the evaluation also included advanced features such as OTA remote upgrades, PACK-level fire detection and protective interlocks, real-time remote control, high-speed multi-stage parallel control, and battery temperature rise/operating condition temperature differences. Notably, all test data significantly exceeded the requirements of relevant industry standards.
The temperature control system plays a critical role in energy storage devices, serving as the key to ensuring the continuous and safe operation of the energy storage system. A liquid-cooled energy storage cabinet is an energy storage device that utilizes liquid cooling technology for heat dissipation. It works by transferring the heat generated within the energy storage system into a coolant, where the coolant’s circulation and heat-exchange properties help reduce the system’s temperature, thereby enhancing both operational efficiency and stability.
This 100kW/215kWh distributed liquid-cooled energy storage cabinet has undergone iterative upgrades by the technical team in areas such as its intelligent temperature control system, structural design, safety features, and highly efficient battery PACK balancing technology. Featuring advantages like cost-effectiveness, exceptional safety, high integration, and smart operation & maintenance, it can be deeply applied in scenarios including distributed energy stations, industrial and commercial energy storage, solar-storage-charging integrated systems, microgrids, and grid substation energy storage applications.
Cost-effective
Highly efficient liquid-cooling temperature-control technology keeps the cell temperature difference within 3°C, enhancing system safety while, combined with an intelligent thermal management system, ensures more uniform battery operating temperatures—significantly boosting conversion efficiency and extending equipment lifespan. Additionally, the highly integrated PACK design delivers a battery cycle life of ≥6,000 cycles, coupled with exceptional charge-discharge efficiency, enabling efficient utilization throughout the battery’s entire lifecycle and helping customers maximize overall system profitability.
Ultimate Security
In terms of protection, the system is equipped with electrical safeguards such as battery overcurrent, over/under-voltage, and high/low-temperature protection devices. For fire safety, it employs pack-level aerosol technology, combined with cluster-level aerosol systems and water spray mechanisms, while also supporting multi-layered fire protection options like perfluorohexanone/heptafluoropropane gas-based firefighting systems. Additionally, this energy storage cabinet features advanced explosion-proof and fire-resistant protection capabilities.
Highly integrated
The entire cabinet features a standard modular design, allowing for quick maintenance and replacement of battery plug-in units and control boxes. Its vertical structure occupies only 1.35 square meters, enabling plug-and-play, decentralized deployment while also supporting scalable expansion—up to a maximum of 20 units operating in parallel. This integrated technology is industry-leading.
Intelligent Operations and Maintenance
Combined with Cloud Energy Cube's independently developed smart grid energy management system, this solution enables real-time monitoring and storage of all operational data from the energy storage cabinet, while also supporting remote control, remote OTA upgrades, and other operation-and-maintenance management functions. This significantly enhances equipment maintenance efficiency, making operations effortless and worry-free.
Keep moving forward without pause, and through practical action, achieve lasting success. This recent achievement of obtaining authoritative testing certification is a powerful testament to the combined strength of the technical teams from Yuneng Magic Cube and Zhejiang Wuyun Energy. Moving forward, both parties will continue collaborating on the development of cutting-edge technologies, delivering safer, more stable, and highly efficient energy storage products and solutions to the market—driving industry-wide technological innovation and elevating product quality to new heights.
