This paper takes a BEV as the target model and optimizes the lightweight design of the battery pack box and surrounding structural parts to achieve the goal of improving vehicle crash safety and lightweight, providing participation in the application of new materials in new energy vehicles.
Firstly, the finite element model of the battery box was established by using ABAQUS. The battery box was geometrically cleaned, the composite material of the box structure and the foam material of the battery module were defined, and the grid was divided according to the process of finite element analysis.
The results show that under the two combined conditions, the maximum stress of the battery box is less than the specified stress of the composite material, and the failure factor is much less than 1, meeting the strength requirements of the battery box. M. Hartmann (2013).
In this paper, the lightweight design and static strength analysis of electric vehicle battery box were replaced by composite materials instead of traditional metal materials. Firstly, the finite element model of the battery box was established by using ABAQUS.
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.
