AI Technical Summary

Technical Problem

Existing battery carriers in electric vehicles suffer from plastic deformation during side impacts, leading to undesirable movement of the battery modules, and current welding or mechanical joining methods increase production costs and time due to tolerance issues.

Method used

An interlock system with roll-formed L-section side profiles and B-section middle vertical profiles, assembled via bushes, transfers impact damage to the middle vertical profiles, eliminating the need for welding and allowing wider length tolerances, enhancing impact resistance and energy absorption.

Benefits of technology

The interlock system effectively absorbs impact energy, preventing side profile deformation and reducing production costs by eliminating tolerance issues, while maintaining structural integrity and reducing assembly time.
