To help car manufacturers with lightweight, eco-friendly electronic models, Autoneum is expanding its product portfolio with Ultra Quiet textile battery protectors that meet specific thermal and acoustic vehicle management requirements electrically. These lightweight parts provide deliver high autonomy and, at the same time, control the noise level.
Autoneum offers a variety of multifunctional components such as carpet, and underbody systems that have a positive effect on the range due to their light weight and are specifically tailored to acoustic and thermal management needs.
Ultra-quiet battery undercovers act as insulators that reduce sound entering the passenger cabin, for example through tires and passing noises. Sound absorption components are also essential for electric models as external and internal sources such as fans, electronic drive components, and pumps are more audible owing to lack of motor noise and thus have an impact on the rules of conduct in terms of comfort. At the same time, textile battery linings need to relieve components by up to 50% less than the corresponding plastic parts, thus ensuring a greater range for driving.
Autoneum also claims that they are also resistant to water, barbs, and vibrations and thus contribute to the protection of the battery compartment. To calibrate the temperature resistance and substrate rigidity, Autoneum utilizes a wide variety of internally produced simulation tools. They are used both in the development phase of new electric models and in the development of models that are already in the market.
The lightweight and ultra-quiet components are made primarily from recycled PET fibers that can be fully regenerated to make them particularly environmentally friendly. They are already used in models of European, American and Chinese manufacturers. From July 2020, the first battery covers of the Gundernhausen factory will be mass-produced for the all-electric model of a high-quality German manufacturer.
