Model 3 LR - battery capacity

[gm12]

Ive been looking for this for ages, and finally found a place where I could find the capacity of the model 3 long range.
I have a 2021 3 LR, and I'd heard a rumour that there was capacity variation across those that were brought into the country.

So I found the answer in redbook.com.au.
2021 Model 3 LR (Jan-Nov) : Battery capacity 74.5kw
2021 Model 3 LR (Nov+): Battery capacity 82kw

Different battery manufacturers, different chemistry, roughly the same range, but if you are using the app "tessie" to measure your battery degredation, the starting kw makes a big difference. It defaults to 77kw (?).

I assume that's because Tesla manufacture commenced out of Shanghai (with LFP batteries) around then?

 

[moa999]

No LFP batteries in LR/P.

Was just an upgrade in the size of the LG supplied battery.

There was a similar shift in the LFP batteries from 55 to 60kWh around the same time.

I had the impression that only the SR+ model had Lithium Iron Phosphate batteries because of volumetric density issues with that chemistry. The P and LR models were still using Nickel Cobalt Aluminium.

In my personal experience, with a Jan 2021 LR (74.5kw). And 40,000km on the clock, my battery degradation is way less than Tesla average, but if adjust the 'starting kw' in Tessie up to 76kw, my degredation then matches Tesla average
Suffice to say, Jan 2021 LR 3 could be anyway between 74.5kw to 77kw based on personal Research, by 74.5kw is the official figure.

I've the same model but from September and only 12,000kms so far. Projected range when new was 547km and now it has dropped to about 530kms, with more of the drop in the past 8 months versus less in the first 8 months. What is your Projected (=EPS) Range now?

I never use projected range, and I don't believe it measures battery degredation.
My recommendation is to get the Tessie app. It will take a few weeks of calibrating before it gives you a result.

I do not think that is the case. Projected range is the EPA constant multiplied by the available battery kWhrs. So in effect it is giving a figure directly related to the capacity of the battery at 100% SOC. I am not talking about estimated range which is something different and based on travel history.

I have had both Scan my Tesla and TeslaMate since day one so I have plenty of statistics & data. From memory I think SmT (querying the BMS) said the battery is a 77kWhr battery with something like 74.5kWhrs available, but one has to factor in the bottom buffer of something like 3.3kWhrs. Discounting the buffer, I have 70.7kWhrs right now or 74kWHrs if I ran from 100% to car stopping.

Another way you can check is to plug into the ODB2 and Scan My Tesla. The ODB2 connection is located behind the panel under the rear airvents.

It'll give live data straight to your phone from the battery and car systems.

The payload includes all these fields: Scan My Tesla readings

Tessie says my "Max range" is 527km +/- 2km

My MiCM3LR 2021(April Build) with ScanMyTesla tells me my battery has a nominal original 74.5kw capacity. My last charge showed 62.1kwh at 90%. Extrapolate that out to 100% and you get 69.0kwh. Buffer is shown as 3.3kwh so Full Nominal Capacity is now 72.3 kwh indicating overall degradation of 3% since July 2021.

Sorry I screwed up the format in my previous reply.

I have an early 2021 Model 3 Long Range (LG battery), from the first MiC batch. I have been using Tessie for about the last 45,000km mileage, nearly 18 months. I have used a starting battery capacity of 74.5kWh in Tessie - I corresponded with the author back when I started using it and we agreed that was the right number for my car.

My car has driven about 64,000km now, and Tessie reports degradation of 4.8% and a maximum range of 520km (give or take a couple of km - it bounces around a bit, but right now it says 520km)

For your reference and comparison, the reported range at 20,000km on my odometer was 530km. It was something like 535 or 540km when the car was brand new.

So in broad figures my car’s range has dropped maybe 10km in the first 20000km, and another 10km in the next 45000km, in each case with a few km of “bouncing around” from day to day, but those are reasonable round numbers for anyone who is interested.

Thanks for that useful info. I have the same earlier LG battery. Seems as if mine is a small amount worse than yours, but not much different and nothing to worry about. I'm very encouraged by your 64K number and the overall trajectory. I mainly charge to 80% and long trips occasionally end around 20%. I might change to 75% as my norm.

 

[gm12]

Great info Ted.
I was worried whether my charging habits had any impact on range. Usually charge to 90% about once per week, but did the trip to Darwin last year where I'd charge to 100% most days
Didnt seem to make any difference.
