You would expect that the estimated range shown in the energy screen would be from the *useable* capacity. Considering the rest isn’t “useable”The method gives you the full pack capacity including the buffer.

You’d expect that, but it isn’t the case.You would expect that the estimated range shown in the energy screen would be from the *useable* capacity. Considering the rest isn’t “useable”
What's more puzzling to me is a brand new Made in China LR (so 78.8kWh LG NMC battery) delivered last week is showing as 74kWh under the same calculation. So that figure would seem here to not include the buffer (3.5kWh on that car)The good news is the method in the sticky still works. We should have clarified there that the result for your battery capacity includes the vehicle buffer.
Interesting but would actually need all the info (rated range, vehicle constant, etc.)What's more puzzling to me is a brand new Made in China LR (so 78.8kWh LG NMC battery) delivered last week is showing as 74kWh under the same calculation.

This is Scan My Tesla data of one, that's an August 2022 of Made In China LR.And I thought the LG packswere never allowed to go to 100% (been a long time since those showed up in Europe but lots of SMT captures with the details elsewhere here), andended up around 75kWh fully charged. I know nothing about 78.8kWh NMC packs. Not saying they don’t exist, just know nothing about them.
Ok, so a lower capacity than 82.1kWh LG pack exists, similar to the 75 vs 78. I guess I have some vague recollection of seeing a scan of this in the past.This is Scan My Tesla data of one, that's an August 2022 of Made In China LR.

But SMT sees 77.5kWh (and projection from 68% also matches) and the energy screen method is alleged to give just 74kWh. So that indicates:If you see only 74 kWh* from a LG 78.8 kWh in a brand new, it is most probably not estimated higher than that by the BMS.
No LG pack is 82.1.Ok, so a lower capacity than 82.1kWh LG pack exists, similar to the 75 vs 78.
Would be good. I think we have the answer: same constants as with the us Panasonic cars. At least it have seemed to be like that, but no one has digged deep into it, so it would be nice getting it cleared.Anyway so we’d need to know the vehicle constant (3 or 4 ways to determine this), the rated range at 100%, and the maximum possible displayed rated range for that vehicle. At a minimum.
I do not think the SMT picture is from the brand new one. At least I read out that from @jyavenard’s posts.But SMT sees 77.5kWh (and projection from
Language and punctuation issue here.No LG pack is 82.1.
Theres the LG M48, 74.5 FPWN
And LG M50, 78.8kWh.

I should have written:
Lower-capacity-than-82.1kWh LG pack.
The SMT screenshot was for a 2 weeks old LR, I had physical access to that car and plugged my OBD2 adapter on it. I didn't at the time knew about using the energy screen to estimate the capacity, so I do not have that data. I could access that car again and check it out again.I do not think the SMT picture is from the brand new one. At least I read out that from @jyavenard’s posts.
Anyway, this should be reflected in the rated miles projected to 100%. It should be quite short of expectations (I don’t know what they are because I don’t know the exact vehicle or how exactly things work with that pack). Anyway, if it is thus reflected, the method is likely working just fine.The 74kWh I mentioned earlier, is indeed a brand new car delivered last week. The owner only ever charged it to 80% so far.
