“Today, says Lanxess, housings for high-voltage batteries are primarily made of extruded steel or aluminum profiles. Depending on the vehicle class, the housing length and widths can be well over 2,000 or 1,500 millimeters”

“The size, the number of components and the numerous manufacturing and assembly steps make metal housings very cost intensive. For example, complex structures made from strand press profiles require many secondary work steps such as welding, punching and riveting.”

 “The material is corrosion resistant and electrically insulating, the latter of which ensures a reduced risk of the system short-circuiting. The low density of plastics and their potential for lightweight construction also lead to significantly lighter housings, which benefits, among other things, the range of EVs.”
