8 terms

battery backup unit technical

"KULR ONE® MAX Battery Backup Unit (BBU) product line designed for AI-scale"

A battery backup unit is a device that stores electrical power and supplies it when the main power source fails, keeping equipment running for a limited time. For investors, it matters because these units protect operations, prevent costly downtime and data loss, and can be critical for businesses such as data centers, hospitals, and manufacturing — much like a spare tire or phone battery that keeps you moving until normal service is restored.

21700 cell technical

"built around a new ultra-high-power 21700 cell platform"

A 21700 cell is a cylindrical lithium‑ion battery cell approximately 21 mm in diameter and 70 mm long, used to store electrical energy for devices, electric vehicles and grid storage. Investors track it because the larger size usually holds more energy and can cut manufacturing cost per unit—like using a bigger fuel tank to travel farther—affecting product performance, production efficiency and profit margins for battery users and makers.

meta open compute project (ocp) technical

"engineered to meet Meta Open Compute Project (OCP) ORV3 standard."

An industry initiative that produces and shares open designs and standards for data-center hardware and infrastructure so companies can build servers, racks, networking equipment and cooling systems from common blueprints instead of proprietary designs. For investors, these shared specifications can reduce capital and operating costs, speed deployment, improve efficiency and increase vendor competition — similar to how shared architectural plans let builders work faster, cheaper and with compatible parts.

ul 9540 regulatory

"lead all UL 9540 and UL 9540A certification activities."

UL 9540 is a safety standard and certification scheme for energy storage systems, such as large battery installations, that checks their design, construction and fire-safety features. For investors it signals whether a storage project meets recognized safety and permitting benchmarks—similar to a building passing inspection—which affects regulatory approval, insurance costs, operational risk and the marketability of the asset.

ul 9540a regulatory

"lead all UL 9540 and UL 9540A certification activities."

UL 9540A is a laboratory test method that simulates how energy storage batteries can fail, catch fire, and spread heat, gas, or flames to nearby cells or equipment. For investors, passing this test can reduce regulatory hurdles, insurance costs, and safety risk—think of it like a crash test for battery systems that shows whether a product is likely to contain a problem or cause a larger, costly incident.

hyperscale technical

"global hyperscalers, cloud service providers, AI data-center operators"

Hyperscale describes the ability of a system or operation to grow rapidly and handle extremely large amounts of work or data. It’s like a massive factory that can quickly expand its production capacity to meet soaring demand. For investors, hyperscale indicates a business’s potential to scale efficiently, often leading to increased growth and profitability.

lithium-ion technical

"high-power lithium-ion backup systems across global hyperscalers"

A type of rechargeable battery chemistry that stores and releases energy by moving lithium ions between two electrodes; think of it as a lightweight, refillable fuel tank for electronics and vehicles. It matters to investors because lithium‑ion batteries are central to smartphones, electric vehicles and grid storage, driving demand for raw materials, manufacturers and related supply chains, and influencing costs, growth prospects and regulatory attention.

hvdc technical

"NVIDIA GPU roadmap for 800 HVDC requirements."

HVDC, short for high‑voltage direct current, is a way of transmitting electricity as a steady one‑direction flow over long distances or undersea links instead of the usual back‑and‑forth alternating current. Like a high‑speed, nonstop pipeline for power, it cuts energy loss and can link different power grids or distant renewable sites more efficiently. Investors watch HVDC projects because they are large, long‑lived infrastructure investments that affect utility revenue, grid capacity, construction and regulatory risk, and the economics of power supply.

HOUSTON, Dec. 17, 2025 (GLOBE NEWSWIRE) -- KULR Technology Group, Inc. (NYSE American: KULR) (the "Company" or "KULR"), a Bitcoin+ Treasury company that builds a portfolio of frontier high-performance energy systems for cross-industry applications, today announced it has entered into a Joint Development Collaboration with a leading global battery-cell manufacturer to co-develop a next-generation KULR ONE® MAX Battery Backup Unit (BBU) product line designed for AI-scale data centers and high-power compute environments.

KULR will lead the design, development, safety engineering, and UL certification of a state-of-the-art BBU architecture built around a new ultra-high-power 21700 cell platform. The collaboration advances KULR’s strategic position in the AI data-center energy market, establishing the foundation for a commercial program with up to $100 million in projected value.

"AI-scale computing is fundamentally reshaping how data centers think about power, safety and reliability,” said Michael Mo, Chief Executive Officer of KULR Technology Group. “KULR has spent years building energy systems designed to perform safely and consistently in the most demanding environments, and this initiative allows us to extend that foundation into next-generation battery backup solutions, purpose-built for modern AI workloads. As compute density and energy intensity continue to rise, we see a clear opportunity to deliver scalable, certifiable battery infrastructure that meets where the industry its headed."

Advanced 21700-Cell Platform for AI Compute, Hyperscale, and Edge Deployments

The jointly developed BBU system will be optimized around an ultra-high-power 21700 cell architecture capable of supporting the next generation of ultra-high-current and high-power AI server workloads.

The platform is engineered to meet

• Meta Open Compute Project (OCP) ORV3 standard.
• NVIDIA GPU roadmap for 800 HVDC requirements.
  
  

KULR will provide system-level architecture, thermal-management engineering, propagation-resistance design, and lead all UL 9540 and UL 9540A certification activities. The partner cell manufacturer will support cell-level integration and provide technical resources as needed.

Long-Term Supply Commitment Supporting Commercial Scale

Upon successful UL 9540 certification, KULR’s joint-development partner has committed to supplying its ultra-high-power 21700 cells for the newly developed BBU product line throughout the lifetime of the program. This ensures KULR has predictable, scalable, cost-controlled access to premium high-performance cells as it moves into commercial production.

This venture accelerates KULR’s continued efforts to meet growing global demand for safe, certifiable, high-power lithium-ion backup systems across global hyperscalers, cloud service providers, AI data-center operators, and system integrators.
