What do you want protecting your BEV?

ǿմý Provides Superior Steel Solutions

C-STAR™ Protection 

Modern vehicles use a variety of structural components to protect passengers and internal systems. In the event of a collision, you want the structural components to absorb energy and/or deform in a controlled and predictable way.

Cliffs’ Steel Tubes As Reinforcement – known as C-STAR™ protection ─ when used in combination with structural components, contributes to the ability for structural components to absorb energy and/or deform in a more controlled and predictable way.

A C-STAR structure may be used in electric, hybrid, or ICE vehicles as reinforcements in rocker panels to protect passengers and/or batteries from a side-impact collision. C-STAR protection may also be used to protect motors, engines, electrical components, passenger compartments, storage compartments, and any area in a vehicle where this design is implemented.

Benefits

  • Cost-efficiency and Sustainability
  • Scalability to meet different performance requirements
  • Manufacturability
  • Less product design space requirement

 

ǿմý Battery Enclosure 

The ǿմý 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.
