Finally, based on the static and dynamic analysis results of the battery box, the weak points and unreasonable points are improved. The results show that the modified model has a good improvement effect and has basically reached the established design requirements, which verifies the rationality of the structural improvement scheme.
In this study, a design optimization methodology is proposed to optimize the features of mechanical design (e.g. minimization of mass, maximization of minimum natural frequency and minimization of maximum deformation) of the battery pack enclosure. The proposed methodology is comprised of four phases.
By analyzing the modal characteristics and the harmonious response to vibration characteristics of the battery box, the dynamic performance of the battery box has been comprehensively mastered. Finally, based on the static and dynamic analysis results of the battery box, the weak points and unreasonable points are improved.
Sci. Eng. 688 033082 DOI 10.1088/1757-899X/688/3/033082 As an important device to protect batteries in electric vehicles, the dynamic and static performance of the battery box is closely related to the safety of the whole vehicle.
Based on this, the ANSYS software’s topology optimization tool was utilized to successfully reduce the weight of the box by 6.8%. Following finite element analysis, the battery box’s performance satisfies the necessary standards in all aspects, demonstrating the viability of the lightweight solution.

Another important contribution comes from the sandwich structure, which is constituted by the passenger compartment floor and the underbody shield; sometimes, but not in all the existing solutions, the battery pack structure gives a contribution (see Figure 2) through specific structural components that are part of the battery case.
