And I did that today, to my surprise the nominal max is now 76.8, up from 76.1. Not doing anything special, just charging 60-80% every 2-3 days.I'll peek every now and then into SMT to check the state of the battery ...

You know that the up-ing is the BMS value only and that the battery itself dont get better capacity?And I did that today, to my surprise the nominal max is now 76.8, up from 76.1. Not doing anything special, just charging 60-80% every 2-3 days.
I ordered a model 3 SR+ which originally would have been delivered in time for my daughter's 16th birthday (end of October).
Yesterday I got an email stating that due to battery issues the delivery has been postponed now to end of December or January (which is still not guaranteed).
I was given the option to have a faster delivery which would likely make it in time for the birthday so I am torn.
The battery option is the LG battery from Europe/Asia. It has a stated decreased 10 mile range (253 vs 263).
I did some research and it looks like it is iron based instead of nickle (and people stated that iron can be charged to 100% without much degradation (and also longer battery life I think).
I was curious what thoughts are on this. Would you wait for the Panasonic Nickle batteries if they are better (I'm not even sure if they are better or not) but hate to lose the 10 miles of range.
The price was quoted as the same for both options.
Thanks
On the same philosophy the original "downing" is also the bms.You know that the up-ing is the BMS value only and that the battery itself dont get better capacity?
What about trying to only charge below 60% ?
The BMS:es are good but cannot bee 100% correct every day.On the same philosophy the original "downing" is also the bms.
I'm aware these are just estimations and it's my OCD acting up.... but still I cannot go over the fact that the battery lost some capacity in only 3 months and less than 9k km.
Why can’t you get over it? This seems like a completely normal thing. When would you expect a battery to start aging? Do you expect the aging to be fastest at first, or faster later in life?but still I cannot go over the fact that the battery lost some capacity in only 3 months and less than 9k km.
Then, it is a little puzzling to me that you did not expect a relatively rapid capacity loss. You’re apparently doing worse than average, but still, capacity loss should be fully expected on every single vehicle.(I'm working with li-ion batteries for quite some time, I'm very familiar with their behaviour in various chemistry implementation and charge/discharge situations).
I do not have my home charger installed yet in my garage (stupid bureaucracy)
Especially as it is a three-year lease, as I recall.If you cant, because of no home charcer etc, no problem at all except that you probably cause a little more degradation. No problem with that.
If I'd know why I can't control my OCD I'd probably be a millionaire by nowWhy can’t you get over it? This seems like a completely normal thing.

As for the "normal thing" .. yes, degradation is normal and expected ... but not in 3 months, not by 5%. The thing that bugs me is not understanding why. I can live with a lower capacity battery, that is not the issue .. the question WHY is the issue.
In my RC hobby I use some really high grade li-ion batteries, that can sustain 5C charge and 20C discharge ... and those I expect to lose capacity quite fast, and they do (I charge them at 1C and discharge them at 15C, always in 5-100% cycles). They are rated for max 300 cycles so, by 30 cycles (which can happen in a week time) I expect it to see the capacity down by 10% (which usually happens).
In a battery that is rated for 1500 cycles, I expect to see maximum 1% degradation after 30 cycles in less than 3 months and about 4% after a year. It is a matter of predictability, nothing else. So far, the predictability algorithm is kind of all over the place ... and that is my problem.
Once I would have understood the reasons and mechanisms behind what I see I will probably be able to rest and leave everything behind
From research we know this:but not in 3 months, not by 5%. The thing that bugs me is not understanding why. I can live with a lower capacity battery, that is not the issue .. the question WHY is the issue.

Thank, i have update my file.I believe some stuff doesn't need a question mark:
- SR+ E6LR is confirmed with WLTP 491km.
- SR+ E6LR is, according to the docs, confirmed with 60kWh.
- LR E5LD is confirmed with WLTP 614km.
Right now the Performance is only certified with the 3L Panasonic, but it is still likely that in the first weeks of October we see the release of V20 and in it the introduction of an E5LD performance. Tesla won't ship those Panasonic's forever, if they can avoid it.Do you confirm that the China Model 3 Performance will be equiped only with Panasonic ? No LG for Performance ?
Hello,Where are you getting the charge times for 10-80% from for the E3LD packs? Because they do not match what eivissa has shared before regarding them. I get it to be around a 5 minute difference in 10-80% between E3LD and E3D. That would also mean the difference to the E5D matches the differences that has been shown as well because in your table it doesn’t.
Ok, lets wait for the v20 thanks.Right now the Performance is only certified with the 3L Panasonic, but it is still likely that in the first weeks of October we see the release of V20 and in it the introduction of an E5LD performance. Tesla won't ship those Panasonic's forever, if they can avoid it.
V20 might also include the list with the 2022 model year upgrades.
I think October will be an interesting months for us.
Hello,
I think the charging time for E3LD have been improved over time so i can update my table.
10 - 80% on E3LD could be around 30 minutes, what do you think about this ?
