The advancing electrification of mobility is raising the requirements for the car of the future. Continuous improvement of the driving range, a higher energy efficiency and more driving comfort are essential for new generations of electric vehicles. As partner to almost all electric vehicle manufacturers, Autoneum is developing products that optimally meet these distinct specifications for acoustic and thermal management of electric vehicles. In the absence of engine noise for instance, sound sources that are new or were previously drowned out, such as fans, pumps or high-frequency noise from the electric motor come more into focus and have to be treated accordingly. In addition, rolling noise is more dominant as the battery increases a vehicle’s weight significantly. This is remedied by acoustic components designed to make the car not only quieter but also lighter, thus ensuring a greater driving range.
Like cars with a combustion engine, electric vehicles rely on heat-insulating parts that protect the passenger cabin from cooling or heating, thereby significantly reducing the energy spent on temperature. Since particularly low or very high temperatures have a negative effect on battery performance, components need to guarantee constant temperature and a correspondingly optimized battery capacity.
