Charging amps isn't as important as charging power as the Superchargers are clearly limited by power not amperage. The Model 3 pack does reach just under 700A when starting from 0% SOC and under ideal conditions but the amperage quickly decreases as the voltage rises. They are about 350V nominal in a 96s configuration. The CT, and I strongly suspect all cars with 4680 cells, will likely be a 108s configuration. This matches the new S/X and reduces the needed amperage for a given charging power level.Thanks. I guess it all boils down to charging amps. My understanding is that the pack voltage is 350 nominal, which puts charging amps around 700. The amps are spread more or less evenly over all the cells, and since the Cybertruck will have a larger battery, the actual charging amps per cell will be lower than 2170. So the 250kW rate (700 amps) can be maintained longer for the 4680 since each cell isn't charging as fast as 2170 and therefore doesn't produce as much heat. I think that means charging times will be the same as if the battery were 2170 even though the 4680 will maintain 250kW longer. Does that sound correct?
All of this is really not that important though for Cybertruck charging speed. The fact that V3 Superchargers are limited to 250kW (apparently) means the much larger (~200 kWh) battery in the Cybertruck will take 50% longer to charge in many scenarios than the Model 3/Y. Since the Tri Motor Cybertruck also has a range that's about 50% further than the Model 3/Y, the average mi/hr charge rate at a V3 stall will likely be somewhat similar between the 3, Y and CT.
