So assuming the 2022 LR3 and LRY have the same battery packs from Fremont, how does this data look?

Predicted Range (rated 330)

Obviously there could be slight errors since the 19% added has no decimals so hard to tell if it’s 18.5 or 19.4 or somewhere in the middle.

100% to 0% on the screen is 95.5% of the total capacity as the buffer is 4.5%.From this we can draw the conclusion that the data is not reliable. You need a much higher number in the added value, and also a higher delta SOC.

If the battery is the 82.1kWh, 82.1 x 0.955= 78.4kWh is the expected capacity between 0 to 100% SOC. We have almost not seen any batteries that reach 82.1kWh capacity according to the BMS so about 80-81 kWh is more probable.

It looks like you charged to 50%. How many rated miles did the car show on the screen at 50% charge?

Just happened to be when I unplugged so it wasn’t that I set it to charge to 50%. I didn’t glance at screen but according to TeslaFi, rated range at 50% was 163 or 326 full.

100% to 0% on the screen is 95.5% of the total capacity as the buffer is 4.5%.From this we can draw the conclusion that the data is not reliable. You need a much higher number in the added value, and also a higher delta SOC.

Should be going from around 20% to 90% today but might get broken up with a lunch trip. I’ll post that data later.

Currently 30% added is 24.71kwh (82.37kWh)

 

[Mrbrock]

Ok, here is full charge data. Range = 295.37 miles @90% (328.2 calculated 100% range)

80.14kwh calculated usable battery size. +4.5% buffer = 83.9 kwh total pack size, 333.9 calculated total range based on miles added

Where are the extra 6 miles of calculated range and 1.9 kwh calculated battery size coming from? Is 19% to 90% not enough or is there something wrong with TeslFi calculating actual added kwh?

Sometimes Teslafi data is suspect. But your calculation of 80.14 kWh is the correct method using the data provided, but it actually represents the whole battery capacity, including the buffer. That number is reasonable since your rated range of 328.2 miles is just under the new car rating of 330 miles. So if you had SMT, you would probably see a value pretty close to 80 kWh for nominal full pack value.

Nominal of 78.8 at 357 mi range.

What is difference between Tessie.app and TeslaFi for measuring battery health and degradation etc? Which is recommendable?

 

[Bouba]

Has anyone been bothered about using partial charge to extrapolate the full charge?....for example, my car does over 500 km range...so every percentage point is worth over 5 km. So depending on the time of day a 50% charge is equal to between (for example) 272 to 277 km....which gives a potential full range of between 544 and 554 km.
Would it hurt to have the percentage to one decimal position ?

 

[MrT3]

Would it hurt to have the percentage to one decimal position ?

Even with streaming API data it only ever gives the charge as a whole number. But weirdly Range is given to two decimal places.

Here's a charging graph from Teslamate. The charge level (in green) goes up in large steps, but the range (in orange) has much more resolution.

 

[AAKEE]

With SMT we get the SOC in tenths.
Its easy to find that the SMT ”Full rated range” show a range thats a bit higher and also match the range better for a full charge.
Not a very big deal, as the difference seems to be sround one percent.

Has anyone been able to confirm whether the LG 5L packs are NMC or NCMA?

I dont know.

The 5L capacity is quite small if compared to the NCMA-capacity in articles. Its said to have a higher Wh/kg than NCA, but infact the 5L has a marked capacity thats 4% lower than pana 2170L(3L) and maybe 2.5-3% lower IRL.
Model 3 performance got 3.5% shorter WLTP with the 5L.
Lets hope that we get to see another bump with a new cell in the near future.

Looks more or less like the classic LG M50 cell when comparing capacity. The LG M50 delivers slighty below 18Wh/ cell for low current discharge. Compates to slightly above 79kWh for a whole pack.
And the 5L has 78.8 kWh ”Full Size When New” specified capacity.

Hi, I don't think I posted my latest battery charts here. Here they are.
Thanks to those who help me make them.

Do you know why the consumption for the LR went from 148 Wh/km to 136 Wh/km (and then back again)?

 

[Victor T]

My MIC 60kwh LFP 31 OCT 2021 Built date @4000km 438.25km left at 100% charged screen is 438km... only put in the ODBlink for scanmytesla 2 days ago..... when first got the car 14th Dec 2021 it was hovering 440~442km at the screen Jan was 439km mostly...... No super charging at all except maybe tesla did 35kwh for the first time from data mostly aftermakert charger 16A charging.

Hope this is the best thread to ask this question regarding Charge Stats on my 2 week old M3 LR. The charging stats seem to be confused about my "home" location. A monthly summary provided 2 days ago indicated that all my charging was done at "other" location rather than "home". So I removed and re-entered my address as "home" in the Nav system, and it worked the first night when the car was parked front first into the garage and connected to my Tesla Wall Charger. But last night I backed my car into the garage and used my NEMA 14/50 charger, and the Stats on my app showed last night's charge being "other" again, even though the car was at home. How can I tell the system that both orientations and both chargers are my "Home" charge location?

Today I went for a little drive…I charged up my five month old MIC M3LR with the 75 KWh battery and only 4000+km on the clock (2500miles) to 100%.
It charged to 545 km (339 miles) exactly the same as day one. And I went on a 230 km (143 miles) road trip mostly at 70 mph…old man driving style…and I arrived with 60% battery…using exactly 230 of range. Just for interest it was 20C (68F) but a fierce head wind all the way.
Just thought I’d share that while I sit in the hotel…
