Presentation Summary

Given their position in the vehicle, battery enclosures are vulnerable to crash but also to intrusion. As Constellium continues to study new materials and joining technologies for this important new product segment, it is also creating new testing methods, fixtures and devices. Two major areas of study are leak- and intrusion testing. Leak testing ensures that the enclosure does not allow air or liquid in or out of the enclosure, while intrusion testing confirms that the materials are standing up to potential threats from road debris. The excellent thermal conductivity of aluminum allows the thermal management function to be integrated into the battery enclosure, which reduces potential leak points by moving them to the outside of the enclosure.
