XING Mobility Unveils 800V High-Voltage DC BBU, Setting a New Benchmark for AI Data Center Power Efficiency
2025.11.19
Taipei, Taiwan / Missouri, USA, November 2025 — XING Mobility, a global pioneer in immersion-cooled battery technology and manufacturing, unveiled the industry's first 800V high-voltage DC Backup Battery Unit (BBU) and Power Rack equipped with immersion cooling technology at Supercomputing 2025 (SC25) in St Louis, MO, USA.
Leveraging extensive experience in full-immersion high-voltage battery systems for electric vehicles, heavy industrial equipment, and mission-critical energy storage, XING has extended its patented IMMERSIO™ technology into the AI data center sector. The solution delivers a high-efficiency, high-safety, and easily maintainable power backup architecture capable of supporting megawatt-level AI computing demands. It meets the power distribution specifications of NVIDIA Rubin GPUs, significantly reducing line heat losses while optimizing energy efficiency.
XING Mobility is also collaborating with Acbel Polytech Inc., a global leader in power solutions. This partnership combines Acbel's proven expertise in high-efficiency power conversion and server power architecture with XING's advanced high-voltage DC and immersion-cooled battery technologies. Together, they aim to foster innovation and long-term sustainability in next-generation AI data center power systems.
IMMERSIO™ Direct Cell Cooling Ensures Stable, High-Performance Computing Environments
According to the IEA Electricity 2024 Analysis and Forecast to 2026, global electricity demand is expected to double next year, driven largely by data center expansion. This trend presents a dual challenge: maintaining grid resilience in the AI era while addressing the massive waste heat and overheating risks created by intensive computing workloads.
“At XING, we've already met the toughest standards of high voltage, high power, and extreme safety through our work in EV, heavy-duty equipment and mission-critical energy systems. Now that AI data centers are facing the same challenges—balancing power density, efficiency, and safety—it feels like a familiar track, only this time the race is in the cloud. With our unmatched expertise in high-voltage immersion cooling, Taiwan's strong supply chain ecosystem, and partners like Acbel, we're demonstrating the island's unique strength at the intersection of energy and technology,”said Royce YC Hong, Founder and CEO of XING Mobility.
With a patented active thermal runaway suppression battery management system (BMS), XING enables data centers to maintain stable 24/7 operations, effectively improves power usage efficiency (PUE), and significantly lowers electricity costs. It also offers a ten-year warranty that exceeds industry standards, giving data center operators peace of mind when planning long-term resource allocation.
Partnering with AcBel Polytech to Build a Sustainable Future for AI Power Architecture
In addition to the new high-voltage DC BBU, XING and AcBel have entered a strategic partnership to advance technical collaboration and application development in AI data center power architecture and energy efficiency. The two companies will jointly explore market opportunities in HVDC power distribution and chart new directions for sustainable power solutions.
“In the era of AI-driven high-power, high-efficiency energy demand, AcBel remains committed to delivering power solutions that integrate industrial innovation with sustainability,” said Jerry Hsu, Chairman and President of Acbel Polytech Inc. “By joining forces with partners like XING, we aim to build data center power architectures that balance performance and green energy, realizing a future where technology and sustainability progress hand in hand.”
NVIDIA's technical publications also affirm that future data center power designs should adopt a dual-track approach—incorporating both 800V DC power distribution systems and integrated, time-shifted energy storage solutions. This industry direction validates XING's strategy from day one: developing safe, direct, immersion-cooled technologies and a comprehensive product lineup that spans from BBUs to energy storage cabinets, advancing energy efficiency together with ecosystem partners.
