Quick Takeaways
- Immersion-cooled 800V battery technology enables compact, high-performance EV packaging with improved thermal control.
- Caterham’s Project V showcases how immersion cooling and 800V architectures converge for next-generation electric sports cars.
On December 23, immersion-cooled 800V battery innovation moved into the spotlight as XING Mobility confirmed it will present the world’s first immersion-cooled 800V high-voltage DC BBU at CES 2026. The showcase also features Project V, an all-electric concept car from British sports car manufacturer Caterham, engineered around immersion-cooled battery technology for compact, high-performance EV packaging.
Immersion-Cooled 800V Battery Enables Compact EV Design
At the core of the reveal is XING Mobility’s IMMERSIO Cell-to-Pack platform, a module-free architecture that integrates cells directly into the pack. This approach reduces weight, improves thermal efficiency, and strengthens safety performance, making the immersion-cooled 800V battery suitable for vehicles with tight space constraints and demanding performance targets.
