A pioneering German-Taiwanese collaboration is set to deliver an immersion-cooled, cell-to-pack battery architecture to European OEMs, significantly reducing the development timeline from initial concept to scalable manufacturing.
TAIPEI, Taiwan and GAIMERSHEIM, Germany, Nov. 27, 2025 — XING Mobility, a recognized global leader in immersion-cooled battery systems, has announced a strategic partnership with IDEENION, a distinguished German firm specializing in automotive design and engineering. A Memorandum of Understanding (MoU) was formally signed at XING Mobility’s Taiwan headquarters, with the following key individuals present:
- Royce YC Hong, Founder & CEO, XING Mobility
- Mirko Konta, CEO, IDEENION Automobil AG
This new alliance will introduce an innovative, integrated methodology for battery system design. It will combine XING Mobility’s immersion-cooled cell-to-pack (module-less) architecture with IDEENION’s comprehensive vehicle design and engineering expertise. Together, the partners aim to jointly develop advanced electrification solutions for various applications, including high-performance and commercial vehicles, marine platforms, and energy storage systems, with a particular emphasis on the European market.
“Both XING and IDEENION share a profound drive to innovate and push technological boundaries. We are offering European automakers a truly immersive, integrated battery architecture where the coolant acts as the bloodstream and the channels become the structural framework. Immersion goes beyond a mere cooling technique; it represents an integrated philosophy that contributes to lighter, safer, and more rapidly industrializable electric vehicles.”
— Royce YC Hong, Founder & CEO, XING Mobility
During IAA Mobility 2025, XING Mobility demonstrated its IMMERSIO™ Cell-to-Pack (CTP) system within the Caterham Project V. This showcase highlighted how eliminating traditional battery modules enhances energy density, optimizes space utilization, and provides greater design flexibility—essential elements for nimble, compact, high-performance EV platforms.
IDEENION: Engineering Prowess from Conception to Manufacturing
With over three decades of experience, IDEENION stands as a trusted collaborator for prominent OEMs such as Audi, BMW, and Mercedes-Benz. Its capabilities encompass the entire development cycle, from initial concept and design through prototype engineering, validation, and low-volume production, underpinned by advanced systems integration, digital engineering, and a user-centric design philosophy.
“Our collaboration with XING Mobility naturally aligns with our commitment to delivering state-of-the-art automotive solutions,” stated Mirko Konta, CEO of IDEENION Automobil AG. “By incorporating XING’s groundbreaking immersion-cooled, cell-to-pack systems into our design and engineering capabilities, we will accelerate the development of next-generation electric mobility, meeting the highest benchmarks for performance, safety, and sustainability.”
