2020, 2019, 2018 Model 3 Battery Capacities & Charging Constants

@AlanSubie4Life I have another question if you do not mind answering it. Is the 71 kWh size of my battery the usable size? Does it exclude or include the ~3 kWh buffer beyond driving to zero miles? TIA

As I said that 71kWh includes the buffer (4.5%) so about 67.8kWh usable. (Vs. about 74.5kWh usable when you started.)

I have a 2020 M3P who can I find out what battery and range it has in it?

You have a 77.8kWh battery when new; the current range (the capacity estimate) is displayed in the vehicle.

Thank you!

Question. long range models3 took delivery June 2020. It used to be over 310 if charged for trip,but now maximum for trips charge is 280mile is this normal or my battery having problems? Thanks

Same here, have a 2020 M3P was getting 300 now 268 @ 100%

268 miles for a 2020 is terrible. have you asked tesla re this? even when you got it you already were 10 miles short.

Yeah of course they said it was normal.

what about only getting 300 miles on delivery? surely the car should have been returned. THats like starting with 5% degradation already (remember the car needs to lose like 3kwh (?) before you even see a range decrease)

A tech came to the house reseal my passenger door I told him and was told to charge the car slower. So I started charging at 24amps vs 48 and I've recovered 8 miles in 3 weeks. So I'll keep that up and see where it goes

thats bullshit. range recovery is likely due to the different reasons.

How does your chsrging schedule look?
What charging level do you use? When do you charge( every night? When you get back after work etc? )
How many miles on the ODO?
Do you have it in a garage or outside and what is the typical ambient temps in winter and summer?

Yes, anything slower than 0.25C is considered ”slow charging” and further slower doesnt help. 0.25C = some 15-20kW charging, so max AC charge is slow.

For my 2021 M3P it is like this:
Full range is shown to 80.4kWh.
80.3kWh shows less than 507km(315mi).

More or less no 2021 with the 2170L pack goes beyond 81kWh when you get the car. Some is below 80, My was 80.7kWh.
For this car you can realistically only ”loose” less than 0.5kWh before the range start to go down. If using the full pack when new value, it will be about 1.7kWh before range drop.
I did read Alansubies report about earlier cars showing 79kWh, but as the ”full pack when new” was 77.8(?) I guess thats the fair number to start counting from? Do we know the average NFP from that time(2018 or 19, whwn new?)

Charge when needed, the car is garage kept with Tesla gen 3 charger set to 24amps was 48.

How high % do you charge to?

In general, its better to always connect the charger annd charge every day and not charge to high levels unless needed fotlr that day.

From your range loss in 1-2 years it looks like you would use quite high SOC (charge to high levels, and that it is standing with high SOC for the main part of the time, and also quite warm climate?

On this video her claimed Tesla reset her (1:58) battery and it's been on point since. I asked Tesla and they say they don't reset batteries?

About five months a year where the daily top temp is well above room temperature?
