Cleveland-Cliffs - Battery Enclosure

The Cleveland-Cliffs Battery Enclosure is a sustainable and robust all-steel battery enclosure concept that meets stringent performance requirements. It is designed to fit any unibody architecture connecting to the rockers through the unique L-shaped tubular side rails. Our Battery Enclosure design utilizes an innovative one-piece bottom tray stamped with laser-welded blanks, which eliminates the need for additional reinforcements to protect the battery cells. It has novel L-shaped side rails, pushing the limit of design while providing robust protection for a side impact. The all-steel design utilized here enables a CO2 reduction of more than 70% as compared to a comparable all-aluminum design. It also has the advantage of thermal runaway mitigation.
