Overview of the New 800V Backup Power Solutions

On September 18, 2026, Kuneng Power introduced two next-generation 800V high-voltage backup power products designed specifically for AI data centers (AIDCs). The construction logic of AI data centers is undergoing profound changes, driven by the explosive growth in AI computing power requirements. The industry is rapidly iterating toward high-voltage, high-density, and high-reliability infrastructure, making 800V high-voltage direct current (HVDC) the mainstream technical route. The newly launched CFS80085U lithium battery system and CNS80050U sodium battery system utilize full-immersion liquid cooling technology. Both systems have passed rigorous international safety and compliance certifications, including UL9540A, UL1973, FCC, and IEC62619, ensuring global market readiness.

Technical Deep Dive: Immersive Liquid Cooling Architecture

The core innovation of both systems lies in their full-immersion liquid cooling architecture. By completely submerging the battery cells in an insulating coolant, the systems physically isolate oxygen, fundamentally preventing combustion, explosions, and thermal runaway propagation. This intrinsic safety is critical for the high-density deployment environments of smart computing rooms. Furthermore, the global synchronous heat exchange mechanism maintains the temperature difference across the entire cabinet within 2°C. This excellent thermal uniformity minimizes individual cell degradation, extending the overall cycle life and improving system efficiency by 3% compared to traditional air-cooled solutions. This precise thermal management not only mitigates the risk of thermal runaway but also ensures that the battery management system operates within optimal parameters, thereby reducing long-term operational and energy consumption costs for data center operators.

CFS80085U Lithium-Ion System Specifications

The CFS80085U immersive lithium battery system is engineered for the high-reliability backup needs of core data center operations. Featuring a highly integrated modular and compact design, it significantly reduces the equipment footprint. It is compatible with mainstream two- or three-line power architectures, supporting both new smart computing rooms and retrofits of existing facilities. This flexibility drastically shortens the project implementation cycle, allowing data center operators to rapidly scale their backup power capacities without extensive structural modifications. Tailored for the short-duration backup load characteristics of computing tasks, the system supports a continuous 6C discharge rate, stably providing 10 to 15 minutes of critical backup power to ensure uninterrupted core business operations.

CNS80050U Sodium-Ion System for High-Density GPU Clusters

Addressing the severe power fluctuations during the operation of GPU clusters in smart computing centers, the CNS80050U immersive sodium battery system offers a strategic alternative. Also leveraging full-immersion liquid cooling, it controls cell temperature differences to ≤2°C and boosts system efficiency by 3%. Compared to traditional air-cooled sodium, lithium, and lead-acid backup solutions, the CNS80050U establishes a significant competitive advantage in safety protection, temperature consistency, and spatial utilization efficiency, which are critical when deploying large-scale battery clusters. The sodium-ion chemistry provides high-rate capabilities, allowing the system to support 6C continuous discharge for 10-15 minutes of backup. Additionally, its high-rate fast-charging ability helps smooth out power peak impacts caused by GPU clusters, delivering dual value in emergency backup and grid-side peak-valley fluctuation regulation.

Market Context and Infrastructure Adaptability

These 800V lithium and sodium immersive backup systems are highly adaptable across various computing infrastructures, including smart computing centers, supercomputing centers, and cloud data centers. They are compatible with mainstream power supply architectures such as HVDC, Panama power supplies, and Solid State Transformers (SST). Kuneng Power's extensive global footprint, having provided solutions to over 70 countries, underscores the versatility of these systems. The ability to integrate seamlessly with diverse power architectures ensures that these backup solutions can be deployed in varied geographical and regulatory environments. Beyond the computing sector, the product capabilities extend to professional industrial power supply scenarios, including high-end manufacturing and rail transit, enabling cross-industry application and replication.
