ivilion – Multifunctional structural cooling for EVs

Electric vehicles (EVs) face several key challenges, particularly high costs, long charging times, and limited range. Fast charging is critical to accelerating EV adoption, but it typically generates significant heat, which is often managed only through complex and costly immersion cooling systems.

ivilion GmbH addresses this challenge with innovative battery cooling solutions and advanced battery pack designs for mobility applications. At the core of its technology is a multifunctional cooling structure that simultaneously acts as a cell holder, thermal management system, and structural element of the battery pack. These structures can be directly integrated into the battery, reducing the number of components and system complexity.

This multifunctionality enables cost savings of up to €7 per kWh and improves energy density at the pack level. Additionally, the significantly enlarged cooled surface area achieves cooling performance comparable to immersion systems, allowing for high C-rates during fast charging.

ivilion’s technology supports faster charging, longer driving ranges, and lower production costs—and is compatible with all cell formats and chemistries.

Benefits:

• Cost and weight savings for battery packs through multifunctional cooling structures.
• Ultra-fast charging: Maximised cooled cell surface area, enabling 10-minute charging (4C and above).
• Improved range: ivilion maximises the available space for battery cells, resulting in more than 7% cells per volume.
• Complete recyclability of the cells: Battery cells can be easily removed without complicated disassembly, enabling repairability and single-origin recycling concepts.
