EV batteries typically cover the entire base of a vehicle. The enclosure cover in the vehicle is incredibly important, as it must protect the battery from outside elements and accidents, and it must also contain the risks it could pose to the vehicle and the occupant.
Moreover, as the automotive industry looks to decrease the weight of many components, manufacturers are increasingly changing battery enclosure materials to plastics and composites. To do this, the enclosure must be exceptionally strong as well as heat- and pressure-resistant — all while remaining relatively lightweight. Choosing the appropriate enclosure material before building an expensive prototype, therefore, plays a crucial role in minimizing safety hazards and other costly issues.
Using the Battery Enclosure Material Screening (BEMS) suite of tests developed by UL Solutions, we help automotive original equipment manufacturers (OEMs) and their suppliers choose the most suitable EV battery enclosure materials. Available under UL 2596, Test Method for Thermal and Mechanical Performance of Battery Enclosure Materials, we offer the Torch and Grit (TaG) test and the Battery Enclosure Thermal Runaway (BETR) evaluation.
