Autoneum Unveils Advanced EV Battery Housing Solutions at Battery Show Europe

Autoneum announced on June 2 that it will present its latest electric vehicle battery housing technologies at the Battery Show Europe in Germany. The company will highlight a newly developed battery lid prototype engineered to support evolving electric vehicle platform requirements. The innovative design incorporates a composite structure capable of integrating additional functional layers, including flame-retardant protection and electromagnetic shielding, allowing vehicle manufacturers to tailor the solution according to specific platform and performance needs.

The new battery lid is produced using Spray Transfer Molding (STM), a manufacturing process designed to deliver cost efficiency while maintaining structural performance. Combining glass fiber reinforcement with a polyurethane matrix, the component provides high mechanical strength and enables the production of complex three-dimensional geometries. Its thin-wall construction contributes to lightweight vehicle design, while the STM manufacturing approach delivers up to 30% weight savings compared with conventional production methods.

In addition to the battery lid prototype, the company will showcase several complementary battery protection technologies intended to improve safety and durability. These solutions address critical challenges associated with electric vehicle battery systems, including thermal management, impact resistance, and environmental protection. The technologies are designed to support battery longevity while helping manufacturers meet increasingly demanding safety and performance expectations.

Battery Protection Technologies Featured by Autoneum

The exhibition portfolio includes multiple solutions developed to strengthen battery housing protection and improve occupant safety. Each component serves a distinct role within the battery enclosure system and contributes to overall vehicle reliability.

Among the featured technologies, the E Fiber flame shield functions as a thermal barrier positioned between battery cells and the vehicle cabin, helping to limit heat transfer. The impact protection plate safeguards the battery pack from collisions, stone strikes, road debris, fire exposure, and corrosion originating from the vehicle underbody. Meanwhile, the under-battery shield incorporates Ultra-Silent textile technology to improve thermal insulation performance and minimize heat leakage from the battery housing, supporting greater energy efficiency and battery system protection.
