Despite what people think, not even Elon can violate the Laws of Physics... well, laws of electrochemistry in this case.
This is why my home charging is set at a more "gentle" 30A each night. No point slamming electrons in there too fast when there's no need.
One theory is that fast charging is better for the batteries than trickle charging. It's hard to know what's best without seeing a huge amount of evidence.
My guess: The energy from Superchargers is paid by Tesla and it adds up fast when someone is supercharging (or what appears to be SC) excessively. So excessive users get throttled back to discourage this practice.
Then why should I be penalized for paying $0.15/kWh to $0.20/kWh at an EVGO that has
nothing to do with Tesla? In their Record of Work originally posted above, they said the reason for it was to protect the battery?
So every weekend of every year your hypothetical Tesla owner drives 400 - 600 miles each way.
Come ON. I'm sure you can come up with something a bit more realistic
That's my pattern and the second reason why I bought a Tesla rather than a practically free Leaf (the first being safety). But, I recognize I'm in a unique high-mileage group. However, this throttling seems either excessive, wrongly implemented, or wrongly communicated, at least. My mileage is supposed to degrade slower per mile than that of other high mileage cars because it is across less time; it shouldn't degrade faster per mile than other high mileage cars.
Here is what I think: Tesla designed the car around use of 15k miles a year and 10% DCFC. That works out to 15 DCFC uses a year. In order to accommodate a couple or three standard deviations from normal they considered typical use of up to ~ FIFTY DCFC uses a year. Past that and the owner is an outlier who will have to decide if a Tesla is the right tool for the job.
If that's even close to true, they'd have to reveal it.

"If you Fast Charge Like Me, Tesla will Permanently Throttle Charging."
You must be assuming almost no Tesla will make it to 1,000,000 miles before needing something so expensive to replace it's better to junk it.
Really? I'm pretty sure he has given most of that information in the thread:
- 2015 P90DL
- ~1 year old
- ~30k miles
- ~250 CHAdeMO charges
- ~55 Supercharges
- Next to zero AC charges
Add this (he answered my question about charging to 100%): "No, I usually charge to less than 90%. Sometimes I will charge to about 93% and drive immediately. I virtually never charge to 100% on CHADeMo... I would go so far as to say I never have, but it may have happened once by accident."
Could it be that this restriction applies if you use Chademo, instead of SuC?
I have the same question.
I've read through this entire thread and haven't seen any good conspiracy theories yet. So let me be the first. Could this be Tesla's way of punishing those customers they feel are abusing the SuC system? If they see someone with lifetime free access using the Superchargers almost exclusively they will throttle their charging speeds. This would be equivalent to the cell phone carriers who throttle network speeds of their unlimited plan customers when they think they are using too much bandwidth. Maybe Supercharging is no more detrimental to the battery than any other method but Tesla feels like they need to punish those they think are abusing their charging network.
Conspiracy theories? How about: Chademo is bad since it puts Teslas next to those lesser EV's, giving it a bad reputation.
In both cases, it's hard to understand the outcome working, though; in yours, the SuC would have more users, filling the SuC more, and the users would be spending more time at coffee shops, shopping, etc., to make up for it. It will make their days longer and they'll get to fewer SuC's, but then they'll be out on the road more since they'll have to get more hotels, and end up SuC'ing more unless they can't afford that lifestyle. In case of Chademo conspiracy, it wouldn't reduce their Chademo use, it would increase it, since they'd get relatively more effect from Chademo than SuC (because less effect (slower) from SuC).
