It's amazing to me that, in the aftermath of Battery Day, no one has really focused on the charging implications of the new cell design. The chart presented, if accurate, would indicate that the 4680 cells should take almost no time to fully charge. If that is the case, the bottleneck will move to the charging infrastructure itself and the amount of energy it can transfer. The fact that the CyberTruck and the Semi would be the only vehicles (initially, at least) to receive the new cell design also makes me wonder if Elon has something else up his sleeve for the rest of the fleet, that will still use the 2170 and the 18650 cells. If I were a betting man, I would put some money on the integration/use of supercapacitors.
