About 4 miles per hour. At worst 3. Never 5.How fast would a model 3 charge with a normal 120v outlet, assuming around 10 amps? 5 miles an hour?
But if you're only charging your battery halfway at each charger in order to just make it to the next one and charge again - because you don't want to spend over an hour charging your battery to 80-90%, what's the benefit of the long rage battery?
Deliberately arriving with 20 miles is risky, because headwinds, rain, or even rough roads can reduce range.
That doesn't explain why larger battery Model 3 is also slower than 70 Model S.
Instead Tesla can just do 100/120k mile warranties then just ignore that when a battery fails at 130k and charge just a trade in fee of say $1000 for labor. They can then repair the old battery and use it in another car that fails after 130k.
For DCFC trips it mostly comes down to miles per minute charge rate.If you check out Bjørns video of roadtrip with Ampera/Bolt it shows DC charging speed. Looks like car is limited by how many amps the charger can put out untill the car orders tapering.
Maximum achived 45 kw, doesent say where but likely just before tapering starts on 55% ish SOC. Charger is 50kw 125A.
Bjørn makes a detour for a rare 80kw charger only to find he cant charge there as it`s offline and he dosent have access.
25% SOC = 41 kw
60% SOC = 40 kw
70% SOC = 23 kw
If you arrive with 0% and charge to 60% you will get 40kw charging speed on average and it will take you just shy of 1h.
Compared to any Tesla this is really bad.
"Absolutely not risky"? Do you have weather information readily available with wind direction and velocity for the next 100 miles of your trip? If rain is imminent, do you know how much and over what portion of your next leg?Certainly there are variables, but one you take them Into account for most supercharger legs, deliberately arriving with 20 miles is absolutely not risky.
I wouldn't target less than 20 miles at end of trip, unless coming home from a trip I do frequently. However, lowering speed is nearly always the magic solution."Absolutely not risky"? Do you have weather information readily available with wind directions for the next 100 miles of your trip? If rain is imminent, do you know how much and over what portion of your next leg?
I don't. Even Tesla trip charge predictor graph shows such low rated miles levels as risky.

It was always about density, not speed. Some high profile vloggers impplied about some secret breakthrough, but then it's still secret today.I was expecting the Model 3 to charge quicker than todays Model S, due to improvements in cell chemistry. Remember the 350kW charging is childs play tweet from Elon? If 350kW is childs play, than what is this?
The large form factor of the new cells reduces wall surface vs content. Heat is dissipated slower, cells can't be pushed as hard. You have lower cost by using less metal and rolling up frewer internals, and soldering fewer cells together to make a pack, but charging will be slower.That doesn't explain why larger battery Model 3 is also slower than 70 Model S.
If 70 kW is the peak SC rate for the larger battery Model 3 then we are probably looking at ~ 50 kW for the base version. Fortunate for us the highway efficiency is good, or this would be a less than happy state of affairs. This seems to point towards 3.8 miles per minute charge rate in the base Model 3 at low SoC on the combined EPA drive cycle. Or about 30 minutes when SC jumping.Although absolutely disappointing in itself, these rates are slightly better than I feared based on the released/leaked Model 3 charging picture where the LR version was getting 70.6kW after more than 7 minutes at near optimum SOC.
I remember posts about that. Yours was a prodigious amount of work that was all the more valuable at a time when there weren't superchargers every 120 miles in most of the country. Do you still use it regularly, or just when charging opportunities are sparse?My range calculator that I made almost a decade ago did It involved realtime weather forecasts, including scaling weather for changes with altitude relative to the stations that the forecasts were for. And when you wanted to plan a trip for further out than that, it used historic climatological data.
The Tesla decision to keep the 1860 cells in the higher performance S and X models was a rather loud clue.
It's been published as charge to be gained in 30 minutes, likely at ideal SOC. 130 and 170 miles respectively over 30 minutes. So an ideal average charge rate of 260 and 340mph. Using 236Wh/mi as a fair estimate, that's 61kW and 80kW. True peak charge speed may be a bit above that.If 70 kW is the peak SC rate for the larger battery Model 3 then we are probably looking at ~ 50 kW for the base version.

It's not that much slower than a base Model S, is it? You have to look at the miles added per minute. And really you start with range similar to an S100, so you will not need to supercharge as often as an S75 owner, presuming a home/destination charger to start off your drive.But man.......that slow supercharging.....whew....not sure what to do about that.........

I can't find 30 minute charge data for S75 for some reason, but assuming 90kWh average over an ideal 30 minutes, that's 45kWh or (~280Wh/mi?) 160 miles. So 3LR at 170 miles in 30 minutes is not significantly slower charging than S75. Even if S75 average 100kW, it's a wash. In this metric, Model 3 is a pretty good deal. Due to all the brand hype, and whispers of new Superchargers, of course we were right to hope for more.
