XING Mobility is bringing a technology born in electric cars to the server rooms powering artificial intelligence. The company will unveil BBx800, an 800-volt immersion-cooled backup battery designed specifically for data centers, at CES 2026.
The innovation sounds technical, but the problem it solves is straightforward: AI data centers consume enormous amounts of power and generate intense heat. When the grid flickers or demand spikes, these facilities need backup power that won't fail under extreme stress. BBx800 addresses this by submerging each battery cell in insulating fluid, keeping the system at a steady 25–27°C even during peak loads. That stability reduces the risk of thermal runaway—the cascade failure that can damage or destroy a battery system.
A standard server rack housing this system can deliver 1 megawatt of power for three minutes, or 1.2 megawatts for 90 seconds. That's enough to bridge the gap during rapid power fluctuations or to handle sudden spikes in AI workload without drawing down the main grid.

XING Mobility didn't invent immersion cooling overnight. The company has spent nearly a decade refining 400–800V battery systems for electric vehicles, putting them through 100,000-kilometer durability tests and extreme-condition trials across Europe. That automotive pedigree matters: vehicles demand reliability in ways few other applications do. If a battery fails in a car, people notice immediately. If it fails in a data center, it cascades—affecting cloud services, AI training jobs, and the infrastructure millions of people depend on daily.
The same core technology is now powering Caterham's Project V, an all-electric sports car concept that uses XING Mobility's cell-to-pack architecture to reduce weight while keeping thermal stability intact. Caterham plans to show a production prototype at Tokyo Auto Salon 2026.
Alongside BBx800, XING Mobility is also releasing the IMMERSIO XBE1000, an energy storage cabinet that scales from 200 kilowatt-hours to 1 megawatt-hour for grid-scale applications. The move signals that immersion-cooled batteries are graduating from a niche automotive technology to a core infrastructure solution.
As AI compute demands keep climbing, data centers need power systems that match that intensity. XING Mobility's bet is that the same engineering that keeps a car cool at 200 kilometers per hour can keep a server farm stable at full load.
