An axial and lateral battery crushing using non-linear finite element (NLFE) approach

Since the battery is the most crucial part of an electric vehicle, its safety level has attracted researchers. This work focused on the computational approach of several batteries using non-linear finite elements. The battery types simulated were Lithium-Iron-Phosphate (LFP) 18650, which were produced in a laboratory. A mechanical load simulation scenario follows a condition when an electric vehicle experiences a collision. Here, the battery pack was axially and laterally crushed. The simulation approach is carried out using the LS-DYNA software. The mechanical properties of the battery are obtained from several experimental approaches. Finally, the battery cell is crushed from the axial and lateral directions with a non-linear finite element approach based on the obtained mechanical properties. This parameter will be used in the future to predict the failure of the battery pack due to dynamic loads.
