Tesla model 3 2021 SR+ > cannot change battery size
Hello,
in case of the model 3 SR+ LFP (Shanghai made and sold in the EU) tesla had two battery capacities. Initially a 55kw, then it was upgraded to a 60kw (starting with October the same year). My question is, where can I edit this information as in the list of cars with SR+ and LFP option there is a single entry to choose from? (and it’s not specified either which one the systems thinks it is the default one) Also, I was not able to find any details about which battery pack the planner uses, but since it keeps showing me higher states of charge at arrival than the car does, I assume it makes it’s estimations based on a 60kw pack. So, how can we adapt this to a 55kw (as in my case) car to get accurate estimations? (and for even better experience, if a user knows their degradation, let’s say 5%, it would be nice if we could factor that one as well. This just get’s more relevant as cars age)

PinnedHi @Kalmar Gyula,
Do you mean a usable capacity of 60 kWh?
You should otherwise select the model;
Tesla Model 3 2021 Standard Range Plus LFP

No, I am referring to the issue that there are two different specifications produced in the same year and in the app there is only a single option to choose @Katya Skog .
For Europe (US is again a different story), in 2021, Tesla made two versions of the Standard Range edition (both made in China, both with LFP). In the beginning (of this new intermediary facelift), cars were delivered with a 55kwh battery pack (starting with March/April until September).
Then, sometime during October/November Tesla upgraded the Standard Range edition to a 60kwh battery. (the car is the same, it just go a bigger battery pack, but both are still called Standard Range Plus LFP) Also, from that point on, the Standard Range (2022, 2023) had the 60kwh battery.
So my question is, if I have the initial version (55kwh) how should I choose my options? As there is one option in the app (no reference regarding the battery size), but there are two battery capacities for the same car model and the same year (in 2021).
So this is clearly an issue as the battery capacity of the model influences any range and energy usage estimations… so either those with 55kwh packs or the ones with a 60kwh pack will have misleading estimation by quite a margin.

Do you mean a nominal capacity of 55 kWh? Or do you mean that your vehicle has a useable capacity of 55 kWh?
I also notice I missed your last question;
“if a user knows their degradation, let’s say 5%, it would be nice if we could factor that one as well. This just get’s more relevant as cars age)”
This is handled with the Battery degradation setting.

Hi again @Katya Skog and thanks for the reply again. I wasn’t specifically addressing nominal or total capacity as Tesla calls the models 55kwh and 60kwh, but we can discuss that one as well. These are 55kwh (with a usable capacity of 52.5 kwh) and 60kwh (with a usable capacity of 57.5kwh). So the key in my opinion here is that these are two different battery packes fitted in the same model (in case of 2021 even the same year as I explained above already). So if ABRP takes into account a single model, its clear that the other half of the users with the same car / model year, but different capacity will get missinterpreted ratings. The difference is 5kwh, so that’s about 10%. I also noticed that ABRP somewhat overestimates my range / remaining capacity compared to the tesla app in my car and the difference is consistent with about 10%. (yes, I’ve noticed the degradation field, and that is quite a useful feature)
