Crash Test Behavior

Currently, the batteries that are used in hybrid and electric vehicles can be extremely hazardous in the event of an accident and there are no defined standards to specifically test the crashworthiness of a battery pack. The amount of hazard damage depends on three factors: (1) battery cell chemistry and construction; (2) battery pack and module design; and (3) the integration of the battery pack in the vehicle. The risk of overheating has been reduced by cooling and there has been some research done on the protection of battery packs. Researchers are continually developing tests in order to determine failure mechanisms and hazard levels with finite element (FE) models to validate the results. The ultimate goal is to better understand the crash behavior of batteries in hybrid and electric vehicles and to improve their level of safety.
