application in the development of new energy electric vehicle battery pack brackets holds significant promise for expediting the development cycle and reducing associated costs. Tang et al.6 validated the precision of the side column collision finite element model of the power battery system through vehicle side column collision testing.
In the analysis of the vehicle side impact test, the rigid column invades the electric vehicle, which deforms the sill beam and the side of the battery pack box. Figure 10 shows the distribution of the stress nephogram of the battery pack box during the collision.
As displayed by their research findings, during side column collisions, both the outer frame and internal support structure of the power battery pack experienced striking deformation, while the battery system encountered substantial acceleration impacts across all positions.
