Cell-to-pack integration with 4680 cylindrical cells, launched first in the 2022 Model Y.
Battery pack (67.5 kWh, 445 kg*) serves as the floor and cross-car support for the vehicle, while meeting safety and noise, vibrational, and harshness (NVH) standards.
Cells are assembled into 4 groups of hexagonally packed Tesla 4680 cells, all of which are formed into a single structure by filling the interstitial spaces of the pack with highly rigid urethane foam, which is also directly adhered to the pack lid. Advantages
Improved rigidity and vibration absorption in axial direction, especially when cell-to-cell gaps are filled with urethane foam.
The honeycomb layout is a unique advantage to cylindrical cells that cannot be translated to pouch or prismatic cells.
Enables ease of assembly and reduction in part complexity.
Final assembly is more robust and less prone to quality failure. Drawbacks
This structural pack is NOT serviceable.
