Tesla helped pioneer a shift toward structural battery packs that eliminate traditional modules to save weight and squeeze more energy into a smaller space. But with its latest vehicle, America's EV leader is moving in the other direction in the name of repairability.
Instead of embedding hundreds of in-house 4680 battery cells into a single, tightly integrated assembly, as Tesla did with the structural battery packs found in some Model Ys and the Cybertruck, the Cybercab contains four separate modules of those cells. That means a faulty module can be swapped out without replacing the entire battery pack. Tesla executives explained the decision in a video on YouTube channel of the engineering firm Munro & Associates.
