Charging rate appears to be below 1C

In summary the 4680 ain't that bad. Some people did the test wrong and published data. Then wildfire starts. It is middle of the road. Again. Will go with Tesla long term on battery health. I can deal with a few more minutes to pee. Just waiting for a leap in tech. In meantime cleaner air makes me feel good.

Right. I knew what I was getting into when I bought a Tesla, but I suppose it's true that an average first-time owner might not. I wouldn't hate it if Supoercharging was faster, but the road-trip charge times do not bother me.

It would be great to have charge speeds like BYD, whose "Flash Charge" packs can fill in about 10 minutes! Unfortunately, to get that tech you must:

• Settle for LFP (lower energy density)
• Use a megacharger (1000V and 1000kW+), and
• Live in China (lol)

In fairness it looks like the vast majority of your charging is between 30-65%
Which is GREAT for battery life, quick charges, decent curve etc.

But for the guys pulling a trailer when 90% charge is needed to make it to the next supercharger (in the summer) the tail end of the charge curve is pretty brutal.

My longest charges have been 95.0kWh (12-90%) in 53m, 94.4kWh (9-87%) in 42m and 91.1kWh (15-90%) in 44m. Widest range on the battery I'd have to combine 2 charges, 55.3kWh (5-51%) 18m and 49.8kWh (49-90%) 29m for a combined 105.2kWh (5-90%) in 47 minutes. I'll concede that if you absolutely have to go to 100%, then it's going to push you past the hour mark.

"Few minutes" are actually "few hours" on trips over a certain mileage and/or with trailer loads, which is why ridiculing it is disingenuous.

@Outdoors was just stating facts, I see no ridiculing statements. I think you are just arguing the same thing over and over without understanding (or acknowledging ) the reasoning behind the charging curve at this point.

The oldest playbook in Tesla land is "Oh, yeah, but what if you are towing a big trailer?

I see a lot of pickups on the road where I live and travel, mostly gas and a few electric, very few of them have a trailer behind them and most of the ones that do don't look like they are on a long multi-day trip.

Think about that before saying, "Yeah, but what about trailers". I purposefully do not tow a trailer when travelling long distance and that was also true when all I had were ICE trucks. If you are one of those RV'ers, I recommend getting a 3/4-ton (minimum) gas or diesel truck. Not because an electric truck can't do it, but a trailer tends to more than double the time spent charging. This is true even if you have a truck like the Silverado that slightly edges out the Cybertruck in charging speed, assuming you have appropriate chargers available(and that is a big assumption). In most rural areas the selection of DCFC is not as good and the Cybertruck will often beat the Silverado in terms of miles added during a typical charging stop. But very few 1/2 ton pickups are actually used for long-distance towing.

In other words, this charging speed wailing means very little in the real world. If I had a dollar for every time I saw someone write, "but what if you are towing a big trailer long-distances" I would be wealthier than I already am.

As someone that has used Tesla superchargers 100% of the time(free) for 30K miles, I have noticed that the 500/325KW rate is only during the initial 0-10 percent. At 60% the charging slope will be around 120KW and go to 100KW around 65%. After that, it goes to 96KW down to 86KW till 80%. It will actualy increase back up to 90+KW at 82% till 86%.

250KW SCers which are what I usually am at, take about 35-40 minutes to charge to 80% from 10%. The chargers will also derate and switch to 36KW around 5% of the time and I usually switch stalls to get a different inverter rack that isn't overheating or whatever the cause is. You have to watch it though, because the estimated time will not update even after derating to 36KW.

I really enjoy the FSD(minus the v13+ random hard breaking for birds and squirrels or when blinded by oncoming headlights in 2 lane roads) but the almost daily charging times for my work commute can offset the time saved with FSD. It gives me time to work on other things though while I'm charging.

Out of Spec charging curves appear to match my experiences with the truck. Apparently the last couple of years' S & X have a faster charging curve to 80% but I've never used a loaner long enough to notice it. Don't pay attention to the advertised 325KW range. I hardly ever charge to 100% unless I'm taking a nap during 1K mile roadtrips. You should view the truck from the mindset of having a more realistic range of 200 miles when charging to 80% regularly. It's not good to leave the battery above 80% in the heat so I usually charge to 86% to arrive at home with 80% after work. Sentry and cabin heat protection at 90F will drain about 15% a day. The interior 120V outlets disable once at 10% so I try to never go below 10% either. This makes the true range and amount of stops for charging extremely different than my expectations from the website's advertised charging times.
