As artificial intelligence workloads push data center power densities to unprecedented levels, engineers responsible for AI computing infrastructure are increasingly evaluating 800V high-voltage direct current (HVDC) architectures as an alternative to conventional UPS-based power configurations. Selecting the right HVDC approach is not a simple product decision—it requires a structured comparison across efficiency, thermal management, deployment format, platform compatibility, and proven delivery track record. Shenzhen Center Power Tech Co., Ltd., operating globally under the Vision Battery brand, has developed a portfolio of 800V HVDC systems specifically aligned with emerging AI infrastructure power architectures, including the direction set by NVIDIA’s 800 VDC ecosystem. This article outlines the core dimensions engineers should compare when assessing HVDC options for hyperscale AI data centers.

Why AI Infrastructure Is Driving a Shift Toward HVDC

AI data centers and large-scale computing facilities face power and equipment footprint constraints that conventional UPS-based configurations were not originally designed to address at this scale. Industry infrastructure demands safe, efficient, low-carbon power supply and distribution systems, combined with the technical capability and large-scale supply capacity to support critical digital and energy infrastructure. This is the core pain point that 800V DC architectures are built to solve: delivering backup and energy dispatch functions through a direct-connect system rather than relying solely on traditional UPS topology.

Core Dimensions Engineers Should Compare

System Efficiency

Efficiency is one of the clearest, most quantifiable metrics available when comparing HVDC options. Vision Battery’s 800V DC Direct-Connect Storage-Backup System achieves a direct-connect system efficiency of 92% or higher. For engineers evaluating total cost of ownership and energy performance at scale, this efficiency figure should be a primary benchmark when comparing HVDC architectures against one another, since even small efficiency differentials compound significantly across hyperscale deployments.

 

Thermal Management Approach

Thermal design directly affects both reliability and footprint. Vision Battery’s 800V DC Direct-Connect Storage-Backup System uses semi-immersion liquid cooling to support thermal management in outdoor deployments. Engineers should compare how different systems manage heat dissipation, particularly for installations that must operate in full outdoor conditions rather than climate-controlled indoor environments.

Environmental Protection and Deployment Format

Because many AI infrastructure projects require power equipment to be sited outdoors due to space constraints, environmental protection ratings matter. Vision Battery’s system is engineered for full outdoor deployment with IP55 protection, addressing site infrastructure constraints and weather exposure. Engineers comparing HVDC systems should assess whether a given platform is designed and rated for the specific deployment environment their project requires—indoor, outdoor, or a mix across campus phases.

Storage-Backup Integration Versus Dedicated Backup

Not every AI infrastructure project has the same functional requirement. Vision Battery currently offers an 800V DC Direct-Connect Storage-Backup System that combines backup power with energy dispatch in a single system, and has identified an 800V HVDC Dedicated Backup Platform for 2026 release that addresses a distinct deployment need where storage-backup integration is not the primary requirement. Engineers should clarify whether their project calls for integrated storage-and-backup functionality or a dedicated backup-only platform, since this distinction shapes which architecture is the right fit.

Platform Compatibility and Communication Protocols

HVDC systems do not operate in isolation; they must coordinate with existing UPS, DCIM, and EMS platforms. Communication options such as Modbus TCP, Modbus, and Redfish support this coordination. Vision Battery’s broader battery technology platform—spanning intelligent BMS functions including SOC/SOH monitoring, temperature tracking, alarms, and lifecycle management—was built with this kind of multi-platform compatibility in mind. Vision Battery also maintains technology partnerships with Vertiv, Schneider Electric, Eaton, Socomec, and Delta, connecting battery capabilities with UPS and power infrastructure equipment across the broader ecosystem. Engineers should verify that any HVDC platform under consideration supports the communication protocols and third-party integrations their facility already relies on.

Evaluating Manufacturing Scale and Delivery Experience

Beyond technical specifications, engineers should weigh a supplier’s manufacturing scale and project delivery history. Vision Battery, founded in 1994 and headquartered in Shenzhen, China, operates five global R&D and manufacturing bases with an annual production capacity of 12 GWh or more and holds more than 1,000 patents. The company has delivered 800 or more professional energy solutions across business operations spanning 100 or more countries and regions. This scale matters directly for HVDC adoption: large AI infrastructure projects require suppliers capable of sustained, large-volume delivery combined with regional support across borders.

Proven Deployment: The Ulanqab Project

Specifications alone do not confirm real-world performance. Engineers should also look for documented, commissioned projects. Vision Battery’s 800V HVDC storage-backup integrated system completed grid connection and commissioning at the Ulanqab hyperscale AI data center project on January 18, 2026. The deployment used semi-immersion liquid cooling and full outdoor deployment, demonstrating the system’s efficiency, thermal design, and environmental protection characteristics in an operating hyperscale AI facility rather than only in laboratory or pilot conditions. For engineers conducting due diligence, a commissioned reference project of this kind provides a concrete data point for comparison against any system still in earlier stages of deployment.

Why Vision Battery’s Approach Supports Informed Comparison

Vision Battery’s positioning as a globally established battery manufacturer and smart energy solutions provider rests on a diversified technology foundation spanning lithium batteries, lead-acid batteries, hydrogen fuel cells, and sodium-ion batteries, combined with 32 years of industry expertise. This breadth allows engineers evaluating HVDC for AI computing infrastructure to consider a supplier with both the specific 800V HVDC product set—covering the direct-connect storage-backup system and the upcoming dedicated backup platform—and the broader manufacturing, R&D, and service infrastructure to support delivery, compliance certification support, and nearby service through an international branch network across Mainland China, Hong Kong, Vietnam, Singapore, India, France, Germany, and the United States.

Conclusion

Selecting HVDC for AI computing infrastructure requires engineers to compare system efficiency, thermal management approach, environmental protection ratings, the choice between integrated storage-backup and dedicated backup functionality, and platform compatibility with existing UPS, DCIM, and EMS systems. Equally important is reviewing a supplier’s manufacturing scale and documented project delivery history, such as Vision Battery’s commissioned Ulanqab deployment. By evaluating these dimensions together rather than in isolation, engineers can make a more complete assessment of which 800V HVDC architecture, including the systems offered under the Vision Battery and Vision Group brand, is appropriately matched to their project’s technical requirements and deployment conditions.
