Electric Vehicle Battery Assemblies with Improved Safety and Less Mass

Summary

Researchers at Purdue University have developed a crushable cooling column in a snake shape for use in electric vehicle battery assemblies. The purpose of this column is to provide thermal management access to each battery cell, locate each battery cell, and provide system rigidity during normal operation. Furthermore, this technology will increase safety by absorbing impact energy during a vehicle crash.
