Echion Technologies and Proper Voltage have signed a memorandum of understanding to integrate advanced battery technology into uninterruptible power supply systems designed for AI data centres. The partnership will combine Echion’s XNO battery technology with Proper Voltage’s 480-volt and 800-volt Vault UPS platform to develop a jointly branded system called VaultX. The companies aim to address the rapid power fluctuations associated with AI training clusters, where GPU workloads can create demanding electrical transients. The agreement positions battery-based energy buffering as a potential tool for operators seeking to manage these fluctuations without relying exclusively on additional grid capacity.

AI Training Loads Put Pressure on Data Centre Power Infrastructure

AI training clusters introduce a different set of power management challenges from conventional computing workloads. Graphics processing units can shift tens of megawatts on and off within milliseconds, according to the companies, forcing operators to size utility connections, switchgear and generation systems around transient peaks rather than average consumption. That requirement can increase the infrastructure needed to support high-density computing, even when peak demand occurs for only brief periods. The companies see VaultX as a way to buffer these rapid changes within the facility and help operators use existing grid capacity more effectively.

Grid access presents another challenge for operators expanding AI infrastructure. Interconnection queues in major markets reportedly stretch over several years, delaying the additional electricity supply that new computing facilities may require. By absorbing and releasing energy during short-lived demand swings, an onsite battery system could help manage the gap between a facility’s instantaneous power requirements and the supply available from its electrical connection. However, the approach addresses transient power management rather than replacing the need for adequate grid capacity or long-duration backup power.

XNO Battery Technology Targets High-Cycle Operations

Echion’s XNO anode material forms the battery technology component of the proposed system. According to Echion, the material supports symmetric high-rate charging and discharging, characteristics the company considers relevant to AI data centres that experience rapid changes in power demand. These operating conditions place repeated demands on energy storage systems, making charging speed, discharge capability and cycle life important considerations for facility designers. The company says buffering applications in AI data centres can require up to 10,000 equivalent full cycles annually, a duty profile it designed XNO to accommodate.

The proposed integration will place XNO cells within Proper Voltage’s existing Vault architecture rather than introduce an entirely separate UPS platform. The companies expect this approach to shorten deployment timelines for operators looking to adopt XNO technology. It also connects battery chemistry with the power electronics and system architecture required to manage electricity at the rack level. The commercial proposition will depend on how the integrated system performs under real operating conditions, including repeated power swings and the electrical requirements of high-density AI deployments.

VaultX Targets 1.6MW of Power Across Two Voltages

VaultX is designed to deliver 1.6 megawatts of power and 84 kilowatt-hours of energy capacity, with rack configurations supporting 480 volts or 800 volts. These specifications place the proposed system within the broader effort to develop power infrastructure that can respond to the demands of increasingly concentrated AI computing. The combination of high power output and comparatively limited energy capacity points to a system intended for rapid buffering and short-duration support rather than extended energy supply. Operators will need to assess how its performance, integration requirements and operating economics fit their specific workloads and electrical designs.

Echion and Proper Voltage are scheduled to present VaultX at the 2026 OCP Global Summit, running from Oct. 12 to 15. The event provides an opportunity to introduce the jointly developed platform to the open computing and data centre infrastructure community. The partnership reflects a growing focus on managing power delivery closer to AI workloads as GPU clusters place new demands on electrical systems. For data centre operators, the central question will be whether battery-based buffering can improve the use of available power infrastructure while maintaining the reliability required for large-scale AI operations.
