An accurate finite element (FE) model plays a key role in predicting the dynamic response of the battery pack simulation. In this paper, finite element analysis (FEA) results are compared with the experimental set up of the battery components and a 60-cell battery module.
After modeling improvements, modal frequency error between test and FEA has been reduced to less than 20% for both battery cell components and battery module along with the supporting modal assurance criterion (MAC) correlation results for mode shapes of the battery module.
Modal frequency values for the brick components have been improved by 25% to 50%. For the battery module, swapping of mode shape behavior is observed between finite element model and experimental results. A soft-bond contact is implemented at a challenging interface in the module to improve the modal correlation results.
