Yea, I believe so.Wasn't this thread closed for new messages this morning? Am I dreaming that?
I'm guessing that there was a "behind the scene, administrator discussion" that got it opened back up.

Looks like it. And (at least) one message disappeared.Yea, I believe so.

A) You have those that agree with Tesla, then you have the "experts" that don't
That is a new one. Haven't seen you make that as a point in other threads. Why now?If Tesla would like to absolute minimize the degradation, they would tell us to not charge more than we need*, to charge often and to charge late. It might become a court problem advising the EPA range but suggests to charge to 50% which makes the range to be only half the advertised.
I have posted this information or point a lot of times before, not in this thread I guess but quite often. (If you do not believe me, search for tesla + advice and aakee).That is a new one. Haven't seen you make that as a point in other threads. Why now?
Batteries would last the longest if they were stored in a refrigerator at a very low state of charge. They age the fastest when stored in a hot place at a full state of charge –
The other significant factor that affects calendar aging is the charge state of the battery during storage. At higher charge states cells lose capacity faster. This is a second reason why we have limited our maximum state of charge to 4.15V/cell instead of 4.2V/cell. We also offer the driver the option of charging to only 3.8V/cell (~50 percent) or 4.10V/cell (~90 percent) to further extend calendar life if the full vehicle range is not needed on the next few trips
Sorry. That is very old. Why is it not there any longer? EPA?I have posted this information or point a lot of times before, not in this thread I guess but quite often. (If you do not believe me, search for tesla + advice and aakee).
This is not a very new picture, but it came with a update of the software in model S. Read the bottom line.

Tesla have some battery information, its veryt old but the Lithium batteries still works about the same(we know from research) so most of it still is valid. Search for ”a bit about batteries”.
Not touching any more such disagreements with a 10' pole, it is just getting old IMHO but last sentence would not be a bad idea at all. Of course people will have to understand the limitations that come with engaging such a "magic button" so we would be back to square one. But, I for one would like that button and Tesla advise on how to optimize my battery life based on my driving.Why not ask Tesla to put a button that says optimizing what my charging percentage should be based on my daily driving?
Exactly. Determining what benefit. Well that might be like range mode. Who knows. For those that need that 1.5 extra miles it will help them. For others it may confuse. The button however is an easy way to say. I don't like that. Give it back to me.Not touching any more such disagreements with a 10' pole, it is just getting old IMHO but last sentence would not be a bad idea at all.

Until you are willing to share your BMS data and/or Teslafi data I am not willing to take your word on any numbers. So, we are not talking about 1.5mi difference but probably much higher. Does 15-25mi range difference just under 5 years is significant? What about 10 years, 20 years? 50K, 100K, 200K ... ? Well, yes to some and no to others. YMMVExactly. Determining what benefit.

Sure in time. Gas stations will decline just like the horse stables. Fast chargers will be abound..till then I continue to focus on adoption not pampering.
Don't ask about range mode.. Many 's ago.
You're suggesting that Tesla doesn't want us to take care of our batteries because of the EPA. I would say that's further than the truth because if we look at Tesla, and it's history they really do want us to take care of our batteries, and you know all battery gate issues. Sometimes Tesla goes in and changes things without even allowing us input. Wouldn't you think that they would do the same to preserve the battery and the charging characteristics and the suggestions to the consumer?
Sure. 15-25 is significant, but get up to over 100k miles, and then. You're talking about what @AAKEE is going to help with. That's when it all gets smoothed out.Until you are willing to share your BMS data and/or Teslafi data I am not willing to take your word on any numbers.

I'm right in the middle and the difference between everybody is less than 3 mi
I actually think you have me confused with someone else. I don’t think most people should bother with trying to recover BMS estimated range because it won’t usually work, and it doesn’t change what your pack contains.Recovering your range is a whole different topic @AlanSubie4Life is an expert on.
That's not a completely thing when that's the case that you made in the previous post.That’s a completely different thing.
Teslas approach is that it shall be very easy to own a EV.
The manual is very thin on battery technology, and how to preserve the battery.
We do not need to know anything, as Tesla takes care of this, for example will lithium batteries be destroyed from charging if the cells are sub freezing. We still can connect the car, and set the charging to commence. But the car will heat the battery and it will not be charged at all, until a bit above freezing.
Believing that for example 80 or 90% will cause the minimal degradation, as I have seen numerous posts about here at TMC, is one of the myths floating around.

That does not mention the word "recover" anywhere in the thread. It is not about "recovering" your range, or recalibrating the BMS estimate, at all.Calculating Your Battery's Estimated Capacity Using the Car's Energy Screen

Nothing as complicated as that. I locked it for a bit to try to allow the conversation to cool down some, and then opened it back up after a short time out.Yea, I believe so.

What does this mean? It doesn't make sense.charge at 80 or 90% whether it be 50% or anything less than 100% would be less than the EPA.
@AAKEE was making the suggestion that Tesla does not recommend where owners should keep their car charge to for the best battery health because if they did the EPA would count that as it's rated range. He responded with a chart of some old chart.What does this mean? It doesn't make sense.
?@AAKEE was making the suggestion that Tesla does not recommend where owners should keep their car charge to for the best battery health because if they did the EPA would count that as it's rated range. He responded with a chart of some old chart.
By his basis by recommending that the car be kept at 90, 80 or anything less than 100 would also suggest that his argument is kind of invalid because he thinks the EPA would give them a hard time.
Tesla does make the slider adjustable versus daily versus trip. I think we all know that. That hasn't affected what the range being sold at.
I think that he's confused that I don't agree with his scientific data. The scientific data might be correct, but I just disagree at the point at which it becomes affected to most people. I don't think it's the degree that everybody wants to make it here and the statistics are not there to back it up on long-term usage.
And Tesla hasn't had to change what they're rated range that they sell their cars now have they? If Tesla wants to make the suggestion to 50% then why don't they or like I said, give us a button to optimize based ones box they live in.Im not trying to get into the back and forth here, but I believe I understand what @outdoors is saying. It appears to me that there was some discussion about Tesla range recommendations and EPA.
Without getting into the weeds on that part of the discussion, if a statement is being made that "Tesla does not recommend to owners where to charge their car because that would then be counted as EPA range", my response to that would be "something must have changed, because tesla is actually making that exact recommendation in the Tesla app now, in the US, as of about August of 2023, for both model 3 and model Y owners.
My Tesla app now has a specific recommendation of charging percentage in the app (a specific percentage for each car). This is new, and somewhat unexpected, but it is true, as I see it in my Tesla app for both cars (and its a different recommendation for my model 3 vs my wifes model Y as well).
