Description
Hyun Soo Kim and co-authors put a full-size aluminum electric vehicle battery case through punishing tests, in the lab and in simulation. Their study appeared in 2025. The case must survive bottom impacts, crushing, and constant vibration without endangering passengers. The team ran a bottom impact test, a 200 kilonewton compression test, and a random vibration test, then mirrored each in a finite element model with the same supports and loads.
Predicted stresses and bending matched the real measurements closely. Hot spots sat at corners and frame joints, and peak compression bent the case by less than a millimeter. Vibration shook hardest vertically but loosened no bolts and broke nothing. The authors say the design is verified, and the matched model can drive lighter future cases.
