6 FAQs about [Battery pack load-bearing structure diagram video]

What are the structural components of electric vehicle battery packs?

In the electric vehicle battery pack described above, the mechanical load-bearing functionality is entirely carried by structural components other than the battery packs. For instance, structural components refer to the module casings and upper and lower battery pack covers.

What are the stages of battery pack design?

The stages of battery pack design include cell configuration, structure creation, safety considerations, control systems, and application interface development. Discover the intricate process of designing a battery pack for electric vehicles, focusing on electrical design, mechanical robustness, and thermal stability.

How to optimize battery pack structure?

The structures of battery pack box, lug, reinforcing ribs and module strips are optimized simultaneously under forward and lateral collision extrusion conditions, which further enhances crashworthiness and reduces the weight of battery pack .

How many modules are in a battery pack?

The battery pack comprises of 22 modules, each containing 300 ‘2170’ packs, resulting in a total energy storage capacity of 112 kWh6. The upper cover of the battery pack incorporates three different sheet molding compounds, thermally molded at the top to create a lightweight, high-strength upper cover plate with a thickness of 8 mm.

How does insertion/extraction affect the mechanical performance of rigid structural batteries?

This demonstrates that the insertion/extraction of lithium-ions during charge/discharge alters the crystalline structure of materials, inducing stress due to repetitive volume expansion and contraction. Consequently, the mechanical performance of rigid structural batteries diminishes.

How does a car battery pack work?

Through welding and integration, they form the battery pack. Steel panels are used for the upper and lower surfaces, serving the dual function of protecting the battery and isolating the environment. This design contributes to the vehicle's lower center of gravity, reducing rotational inertia and enhancing stability and handling performance.
