I think that is quite a conservative estimate. For people like me who regularly roadtrip, I would think a 5-10 min time saving should be expected especially when charging from 10% - 80% which is how I most often link charging sessions. I often see 250 kW - so assuming 2070 cell architecture can handle the extra current and heating - this will be substantial.Tesla is upgrading their V3 Superchargers to 324 kW, roughly a 29% speed increase. That will likely only increase Supercharger stops by a minute or so due to tapering, but a minute saved is a minute earned… or something like that. I’m not sure which vehicle’s this will affect.
Depends largely on the batteries and the charge controller on the car. The newer Model S and Model X both charge faster and taper slower so it’s likely they will benefit more than older cars.I think that is quite a conservative estimate.

no matter what I do, warm battery and 20SoC still requires a 40-45 min charger time to 90%.......2020 Model S, "F" battery, 14750 milesNo, that's how it works (and you'll only get that power level if certain conditions are met, such as type of car/battery pack rev, low state of charge, and adequate battery temperature)...
There is a charging curve built in that tapers from maximum power to prevent overheating the battery...

It’s likely more interesting for the Cybertruck and vehicles with bigger batteries because they linger at the lower percentages longer so perhaps it’ll help us by more than just a minute or two.

One other side-note. The Cybertruck may have newer “Tesla Silicon anodes“ which will eliminate much of that tapering. Then we’d get to enjoy the full 324 kW for most of the charging cycle which would be awesome.
Likely unchanged. A high speed home charger would be extremely expensive.and what would be the maximum for home charging
Home charging is maxed out by the circuit available and the bulky charger built into your car, which is usually <12kW.and what would be the maximum for home charging
yes....I currently have 48a with 60a breaker....use it for the 3 and SLikely unchanged. A high speed home charger would be extremely expensive.
Right now it tops off at 48Amps (60 Amp breaker) and it’s likely that’ll be tops for a while.
That’s something like 250 miles added overnight. More than enough to get you to the nearest Supercharger if you want to drive a long distance 2 days in a row.
In regards to home charging, you would never want to exceed about 80% of the maximum breaker rating. I installed a 100A breaker for my Gen1 home charger, which will allow up to 80A for my S85D which has the dual chargers onboard. Honestly though, I typically scale it back to 65A or so in the summer because the HPWC's cable gets HOT when you go the full 80A.Home charging is maxed out by the circuit available and the bulky charger built into your car, which is usually <12kW.
