A key indicator for integral vs differential design of battery packs in battery electric vehicles under structural dynamic loads

Abstract

Battery packs in BEVs are multidisciplinary design challenges balancing cost, weight, volume, range, and charging time. As the heaviest and most expensive component, their reliability and safety under vibration and shock is critical. This contribution presents an indicator to cluster measured vibration data of BEV battery packs based on coupling with the car body, enabling identification of representative designs and generalization of vibration behavior for future, more integrated architectures.
