What exactly is a cell? What is a pack? And why does the distinction matter for EV innovation?
The architecture impacts vehicle cost, weight, range, and ultimately, profitability.
A cell is the basic energy unit; a pack is thousands of cells connected.
Why not one giant cell? Because stresses and heat are too hard to control at large scales. Smaller cells are safer.
Tesla transitioned to larger cells, reducing welds and simplifying assembly for the Model 3.
Assembled packs are complex—they must protect, cool, and monitor thousands of cells simultaneously.
Understanding this architecture is the first step toward a fully optimized EV system.
