Baysafe® EA: Battery Crash Protection
Discover Baysafe® EA for enhanced battery protection in electric vehicles. Our rigid foam is tailored for energy absorption, safeguarding high-voltage batteries from thermal runaway and crash events. With Baysafe® EA, enhance the battery thermal management and improve safety on the road.
Baysafe® EA is an evolution in battery protection for electric vehicles. As the automotive industry shifts towards full electrification, ensuring the safety and efficiency of high-voltage batteries is paramount. Baysafe® EA, a specialized rigid foam, offers advanced energy absorption capabilities, safeguarding batteries from thermal runaway and crash events.
With its lightweight yet robust composition, Baysafe® EA effectively limits mechanical stress transferred onto battery cells up to a compression of 60%1. This innovative foam converts mechanical energy into deformation and heat, regardless of impact direction, providing comprehensive crash protection without predefined load paths.
The easy processing of Baysafe® EA allows for the manufacturing of geometrically complex crash inserts tailored to the available space within the PU battery pack. Its cell structure enables thermal disconnection of cells from external temperatures, improving battery thermal management and enhancing overall performance and longevity.
