A recently granted patent (Publication Number: US11967727B2) discloses a method for manufacturing a crash frame for a battery compartment in electric drive vehicles. The method involves providing metallic sheets, joining them together, introducing a medium between the sheets, applying pressure to cause deformation, and producing a crash frame with wall components and deformation spaces. The crash frame is designed to accommodate a battery housing and includes features for thermal management and protection, such as indentations for sealing compounds and insulating materials in the deformation spaces.

The method includes steps such as bending the joined sheets along bend lines to form wall components, joining the wall components to create the crash frame, and filling the deformation spaces with insulating materials. The metallic sheets, typically stainless steel, can have different thicknesses to define the inside surface of the crash frame. Additionally, the crash frame can be constructed with multiple wall components to enhance thermal management and protection for the battery compartment. The innovative manufacturing process allows for the creation of a robust crash frame that provides structural support and safety features for the battery compartment in electric drive vehicles, ensuring efficient thermal management and protection during operation.
