Abstract: 
This contribution shows an analysis of vibration measurement on large floor-mounted traction batteries of Battery Electric Vehicles (BEV) from some pre-study measurements for a larger test campaign plan. The focus lies on the requirements for a realistic replication of the mechanical environments in a testing laboratory. Especially the analysis on global bending transfer functions and local corner bending coherence indicate that neither a fully stiff fixation of the battery nor a completely independent movement on the four corners yields a realistic and conservative test scenario. The contribution will further show what implication these findings have on future vibration & shock testing equipment for large traction batteries. Additionally, it will cover a look on the needed frequency range regarding potential fatigue damage. For this a Fatigue Damage Spectrum (FDS) on the measured signals is used with respect to potential faults of the batteries.
