6.4. Impact protection strategy In order to evaluate the protective effect of the bottom structure of the battery box, the protective effect (PE) can be calculated by comparing the reduction of the maximum axial compression of the battery under the protective structure with the ratio under the condition of a homogeneous plate.
During the period of 40 ms-60 ms, the maximum stress values of all lifting ears exceeded a certain limit and significant plastic deformation occurred. This means that in the case of bottom collision impact, the lifting ears of the battery pack will experience huge stress, and there is a high possibility of fracture failure.
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.

The first approach is to improve the energy density of every single battery cell. The second approach is to reduce the weight of the battery pack enclosure (BPE) Today, it is very challenging to improve the energy density of battery cells due to the high energy densities already achieved as well as safety-related problems.
When dividing the grid of battery pack components, the smaller the unit size and the more the number, the higher the grid density, which can improve the accuracy and reliability of the calculation and make the simulation results closer to the actual situation. Smaller unit sizes can better capture structural details and deformation situations.
