XING Mobility will present a range of high-voltage immersion-cooled battery systems at CES 2026, including what it says is the world’s first immersion-cooled 800-volt backup battery unit designed for high-power applications such as artificial intelligence data centers.
The Taiwanese battery technology company said the new system builds on its IMMERSIO™ immersion cooling platform, which has been developed and validated through more than a decade of automotive-grade testing. At CES, XING Mobility plans to demonstrate applications spanning electric vehicles, energy storage systems and data center power infrastructure under the theme “A Decade of Immersion Cooled Innovation.”

The newly introduced 800V BBU, known as the BBx800, is designed to support either ±400-volt or 800-volt configurations and deliver peak power of up to 1 megawatt for short durations. The system uses full immersion cooling, in which individual battery cells are submerged in insulating fluid to maintain stable operating temperatures and reduce thermal risks under high load conditions.
XING Mobility said the system addresses growing power demands in AI data centers, where rack-level power requirements have increased sharply in recent years. The industry has increasingly shifted toward higher-voltage direct current architectures to improve efficiency and manage thermal and electrical constraints associated with rising power density.

The company’s expansion into data center infrastructure draws on experience gained since 2015 in developing 400- to 800-volt battery systems for automotive use. Those systems have undergone regulatory certification in Europe, long-term durability testing with Japanese automakers and extreme-environment evaluations with industrial equipment manufacturers, according to the company.
In the electric vehicle segment, XING Mobility is also showcasing its IMMERSIO™ Cell-to-Pack immersion-cooled battery technology as part of its collaboration with Caterham on the all-electric Project V concept car. The battery system is designed to support lightweight construction and high thermal efficiency within the compact packaging constraints of a performance-focused electric vehicle.

Caterham plans to unveil the production prototype of Project V at the Tokyo Auto Salon in 2026, highlighting the transition of the immersion-cooled battery system from concept to a road-ready application.
XING Mobility will also introduce the XBE1000 energy storage system cabinet, which uses immersion cooling to support capacities ranging from 200 kilowatt-hours to 1 megawatt-hour. The system is designed for high-power discharge and grid-related applications, including renewable energy integration and frequency regulation, where space efficiency and thermal stability are critical.
The CES showcase underscores XING Mobility’s strategy to position immersion cooling as a common high-voltage platform across electric vehicles, grid energy storage and AI data center infrastructure, as demand grows for higher power density and improved safety in battery systems.
