While the increasingly complex technical equipment in electric vehicles enhances both driving comfort and safety, it is also susceptible to electromagnetic disturbance.
The latest product from Autoneum Management AG, Winterthur/Switzerland, draws on the company’s experience in the design, development and production of aluminum sheet forming to include battery electromagnetic shielding (EMS). The stamped aluminum components prevent electromagnetic interference (EMI) inside electric vehicles and provide a robust and cost-effective shielding solution for composite battery lids.
Thanks to the very good conductive properties of aluminum as well as the particular design of the components, the EMS improves the function of the battery housing as a highly effective protective shield against EMI. With a shielding effectiveness of more than 70 dB, it not only offers greater electromagnetic protection than alternative methods, is also considerably easier to manufacture.
As a high-quality, robust and cost-effective complement for composite battery lids, aluminum EMS prevents EMI inside the vehicle and thus provide a valuable extension of Autoneum’s textile-based product portfolio for electric cars, which already includes components such as the Ultra-Silent-based front trunks and under battery shields as well as e-motor encapsulations made of Hybrid-Acoustics PET. The aluminum EMS is currently available in Europe, North America and Asia.
