XING Mobility has announced the release of its BBx48 System, a plug-and-play immersion-cooled backup battery unit (BBU) designed to address power and cooling limitations in AI-driven data centers. According to XING Mobility, the BBx48 targets the increased power consumption and heat generated by graphics processing unit (GPU) workloads, which traditional backup systems struggle to manage efficiently.

The BBx48 employs XING Mobility’s proprietary immersion cooling technology that submerges each battery cell in dielectric coolant. The company reports this approach maintains optimal battery temperatures under high-density GPU loads, yielding more consistent power output, extended battery life, and improved reliability compared to air- or liquid-cooled systems.

Engineered for rack-mount installations, the BBx48 provides five times the output power of legacy backup systems and offers a projected operational lifespan of 10 years. XING Mobility notes the module is hot-swappable and integrates with standard data center infrastructure. A single chiller can service up to 40 BBx48 units and the company claims it consumes only 10 percent of the cooling energy compared to conventional methods, which can improve Power Usage Effectiveness (PUE).

XING Mobility states its immersion-cooled BBU technology, previously deployed in electric vehicle and industrial energy storage applications, now equips data centers and edge environments seeking improved power reliability, thermal stability, and operational efficiency. The company also offers stationary energy storage systems for green data center use cases, which will be demonstrated at EES Europe in Munich from May 7 to 9, 2025.
