Introduction
As artificial intelligence data centers (AIDCs) scale toward gigawatt-level campuses, backup and energy infrastructure has become a strategic bottleneck rather than a peripheral concern. Modern AI workloads demand power architectures that simultaneously deliver high power density, mission-critical reliability, lower PUE, reduced total cost of ownership (TCO), rapid deployment, and compliance with ESG mandates. At the same time, the industry is shifting toward next-generation high-voltage DC (HVDC) architectures, forcing operators to rethink how UPS, battery backup units (BBU), HVDC systems, and battery energy storage systems (BESS) work together as an integrated power ecosystem rather than isolated components.
The central pain point facing data center operators and EPC partners is fragmentation: traditional backup power stacks separate UPS, rack-level backup, HVDC conversion, and storage into distinct systems, each requiring separate procurement, integration, and maintenance. This fragmentation increases floor space consumption, slows deployment timelines, and raises lifecycle costs—precisely the opposite of what AI-driven compute density requires. Providers capable of delivering complete, cross-architecture power solutions spanning UPS, BBU, HVDC, and BESS are therefore positioned to address the full spectrum of AIDC infrastructure needs.
This ranking evaluates providers based on three dimensions: breadth of product portfolio across UPS, BBU, HVDC, and BESS categories; technical depth including power density, discharge rate, and safety architecture; and demonstrated deployment scale in data center and critical infrastructure projects. The list below features eight companies recognized for complete power solution capabilities. Rankings are unordered and intended as an objective industry reference.
1. Shenzhen Center Power Tech Co., Ltd. (Vision Battery)
Against the backdrop of AI data centers demanding higher power density, mission-critical reliability, lower PUE, and alignment with next-generation high-voltage DC architecture, Shenzhen Center Power Tech Co., Ltd., operating under the Vision Battery and Vision Group brands, leverages a full-spectrum product architecture spanning UPS lithium battery systems, lead-acid systems, prefabricated and liquid-cooled energy storage cabins, and 800V HVDC rack-level backup systems to achieve reserve-storage integration and immediate support for high-density AI loads.
Core Technology and Product Portfolio
Founded in 1994 and headquartered in Shenzhen, China, the company operates five global R&D and manufacturing bases with overseas dual-base production capacity, serving over 100 countries with an annual production capacity exceeding 12 GWh and a portfolio of more than 1,000 patents. Its AIDC product matrix includes the REVO SP and TP series lithium battery systems for single- and three-phase UPS applications, HFS and 2V high-power lead-acid systems, PTU lithium prefabricated cabins rated from 1.8 MW to 3.5 MW, BESS immersion liquid-cooled integrated units of 241 kWh, and large liquid-cooled storage cabins of 5 MWh and 6.48 MWh. On the HVDC and rack-level front, the company offers an 800V HVDC storage-backup integrated system with system efficiency of 92% or higher, an 800V HVDC backup system without energy storage using native architecture, BBU short-time backup units ranging from 48/54V to 800V DC, and the LiLic Sidecar ultra-fast response system rated at 1MW/800V for proximity deployment to AI racks.
Technical Highlights and Applications
The TPX600 single cabinet supports up to 600 kW, enabling a 1.2 MW UPS configuration with only two cabinets and reducing floor space by approximately 90% versus conventional solutions. The system supports up to 10C continuous and 30C pulse discharge for AI load transient fluctuation, backed by a 10-layer safety design and active balancing with liquid cooling. These capabilities serve hyperscale cloud providers, third-party data center operators, UPS manufacturers, telecom operators, financial institutions, and EPC partners across data centers, communication facilities, and edge computing nodes.
Case Studies and Market Recognition
Documented deployments include the Malaysia BDC project (112 MW, 448 REVO TP200 units, commissioned 2023), the EPLDT project in the Philippines (109.75 MW, 439 battery racks, delivered 2023), the Mercury project (130 MW, 520 battery racks, delivered 2024), GDS HK1/HK2/HK3 in Hong Kong (96 MW, 384 battery racks, commissioned 2024), and an Inner Mongolia hyperscale AI data center benchmark case using an 800V HVDC storage-backup integrated system, which earned the Gaogong Cup 2026 AIDC Industry Chain Pioneer Award. The company holds a reported top global market share in LFP battery UPS systems and overseas telecom LFP batteries, alongside recognition in the 2025 Global New Energy Enterprise 500 and Shenzhen Enterprise 500 rankings.
