XING Mobility Launches BBx48: Industry-First Immersion-Cooled BBU That Rewrites the Rules of Data Center Backup Power
2025.05.05
TAIPEI, Taiwan, April 30, 2025 (GLOBE NEWSWIRE) -- XING Mobility, Taiwan’s pioneering force in immersion-cooled battery systems, today announced a transformational leap in data center backup power with the launch of its BBx48 System—a plug-and-play, immersion-cooled backup battery unit (BBU) engineered to overcome the critical limitations of conventional power systems in the age of AI.
As the adoption of GPUs and AI workloads surges, data centers face unprecedented challenges. Training AI models demands exponentially higher power consumption and density, generating immense heat that traditional BBU systems struggle to handle. This leads to drastic drops in battery efficiency, shortened lifecycles, and reduced reliability—putting mission-critical operations at risk.

XING Mobility BBx48: Immersion-cooled BBU for AI data center resilience
AI-Ready, Rack-Optimized, and Sustainability-Focused
Tailored for modern rack-mounted deployments, BBx48 delivers five times the output power of legacy systems and offers a 10-year operational lifespan. It integrates seamlessly into existing infrastructure with hot-swappable modules, while a single chiller supports up to 40 units—consuming only 10% of the cooling energy compared to conventional systems and significantly improving PUE.
This is not just a BBU—it's a thermal and operational upgrade purpose-built for the AI era. With BBx48, backup power is no longer the weak link in the data center—it becomes a strategic asset for scalability, efficiency, and resilience.
From Electric Supercars to Data Centers—A Proven Technology, Reimagined
With a heritage of high-performance EV and energy storage innovation, XING Mobility brings its field-proven immersion cooling to the frontlines of digital infrastructure. The BBx48 System is now available for next-generation data centers and edge environments seeking breakthrough performance, sustainability, and thermal stability in an increasingly power-hungry world. Expanding beyond rack-level backup, XING Mobility also provides a stationary energy storage solution for green data centers, which will be showcased at EES Europe, May 7–9, 2025, Messe München, Booth C2.270.
