XING Mobility will unveil an 800V immersion-cooled high-voltage DC backup battery for AI knowledge facilities at CES 2026, marking a significant growth past its automotive roots.
The corporate will current the system, often called BBx800, as a part of its CES showcase themed “A Decade of Immersion Cooled Innovation.”
The exhibit brings collectively XING Mobility’s battery deployments throughout electrical automobiles, vitality storage programs, and knowledge heart infrastructure.
The 800V backup unit will make its public debut on the present.
BBx800 is designed particularly for high-power AI knowledge facilities. It makes use of full immersion cooling, inserting every battery cell immediately into insulating fluid.
The design maintains working temperatures between 25°C and 27°C over lengthy intervals.
The method goals to scale back thermal runaway threat and enhance system stability underneath excessive masses.
The module measures 2 OU in peak and helps voltage configurations of ±400V or 800V.
An ordinary 20 OU rack can ship peak output of as much as 1 MW for 3 minutes, or 1.2 MW for 90 seconds.
The system targets short-duration backup wants throughout fast energy fluctuations and peak AI workloads.
AI drives voltage shift
Rising AI compute density has pushed knowledge heart energy necessities sharply increased.
Per-rack demand has elevated from roughly 100 kW to greater than 1 MW in some deployments.
Conventional 48V architectures face rising constraints linked to present ranges, thermal stress, and effectivity losses.
In 2025, NVIDIA introduced plans to advertise an 800V high-voltage direct present structure for next-generation AI knowledge facilities.
The upper-voltage method lowers present and improves effectivity however introduces new engineering challenges.
These embody insulation design, fault isolation, thermal runaway mitigation, electromagnetic compatibility, and security certification.
XING Mobility positions BBx800 as a response to these challenges.
The corporate says immersion cooling allows tighter thermal management at excessive voltages whereas enhancing security margins.
The design additionally permits excessive energy density inside a compact rack footprint.
Automotive validation underpins design
XING Mobility’s transfer into knowledge heart infrastructure builds on practically a decade of automotive growth.
Since 2015, the corporate has labored on 400–800V battery programs certified for automobile use.
That work included European regulatory certification, 100,000-kilometer sturdiness testing with Japanese automakers, and extreme-condition trials performed with Kubota.
These applications required options for high-voltage insulation, electrical shock safety, and thermal administration underneath steady stress.
The corporate now applies that have to stationary backup programs, the place failure tolerance stays low.
The identical immersion-cooled platform additionally helps Caterham’s Mission V, an all-electric sports activities automotive idea.
The automobile makes use of XING Mobility’s IMMERSIO™ cell-to-pack structure to scale back weight whereas sustaining thermal stability.
Caterham plans to unveil a manufacturing prototype at Tokyo Auto Salon 2026.
Alongside BBx800, XING Mobility can even debut the IMMERSIO™ XBE1000 vitality storage cupboard.
The system helps configurations from 200 kWh to 1 MWh and targets grid-scale and high-power purposes.
With BBx800, XING Mobility alerts that 800V immersion-cooled batteries are not restricted to automobiles, as AI knowledge facilities drive demand for safer, denser, and extra environment friendly energy programs.
