At the heart of every EV lies a remarkable technological innovation – the battery module. These compact, powerful energy storage units are revolutionizing the automotive industry and have become the backbone of sustainable transportation. Central to the development of high-performance EVs is the design and engineering of the battery module.
With the optimal design, the deformation of the three positions with the maximum deflections of the power battery pack is reduced, which can help to prevent the risk of electrolyte leakage caused by impact and collision of the power battery module, resulting in improved safety of the electric vehicles.
In the structure of new energy vehicles, the power battery pack structure is the most important power component, thus, it needs to be designed with a safer and more reasonable structure to meet the requirements of shock resistance and durability.
The power battery is the only source of power for battery electric vehicles, and the safety of the battery pack box structure provides an important guarantee for the safe driving of battery electric vehicles. The battery pack box structure shall be of good shock resistance, impact resistance, and durability.
A battery module is a complex assembly of individual battery cells, housing, thermal management systems, and safety mechanisms. Selecting the type of cells to be used in an EV battery module is a crucial decision that impacts the vehicle’s performance, range, safety, and cost.
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.
