Jack Rickard shows both cables next to each other in this video at about 1:16:00. (I recommend 1.5x speed, more if you hail from New England.)Ingineer discovered that the cable between the charge port and the battery was a 3-0 cable and was bigger than model S. It's in one of his videos. He claimed to have the mfg's specs on that cable and said it was good for 430 amps but I'm not sure if that's a continuous rating or not. Most conventional copper 3-0 cable are only good for low 300 amp range so 430 seemed pretty racey at the time.
Now we have people saying that tesla could be pushing anywhere from low 600 to 700 amps thru that cable.
What do you think about that??
I thought I'd seen that the V3 spec out at 500V. It appears Tesla is staying at 400V packs and not venturing to 800V as VW Group is with the Taycan and e-tron GT. It looks like the Megachargers are going to be 4 parallel 400V cables into the Semi and will keep everything 400V.Any thoughts on potential voltage changes to the pack that would lower the current needed to achieve 250kW+?
For example, at 700V you would “only” need 357A, which would be within cable specs.
That might necessitate a re-wiring of the pack though, which I’m not sure can be done on the fly for he entire M3 fleet..
Sounds like pack manufacturing will simplify with the removal of the MR option.SR and SR+ are same pack. 3 packs for M3 (SR/SR+, MR, LR), each will have its own 1PH or 3PH variant for international.

I’m curious to see if there are any manufacturing changes with the new modules that will be noticeable to customers. Other than making them lighter, gettig rid of the oil canning noises during charging would be nice to see.
This brings up an engineering trade I hadn't previously considered. There are a number of constraints when designing the new modules but they could have considered adjusting the cell fore-aft position to optimize vehicle weight distribution, presumably to 50/50. If the SR/SR+ cars with the new modules have equal weight on the front and rear axles (with driver), I would infer that there are no plans for an AWD variant with the SR battery (on either 3 or Y). But if the SR cars are rear biased, that leaves open the possibility for the release of dual motor cars which would move the distribution forward.New modules (not depopulated) aren’t shipping yet. New springs for front suspension due to weight balance is really the only change.
As stated in the other thread, your data appears consistent with previous Supercharging data and therefore doesn't indicate 2019.8.5 included a new charging profile.
