2021 model Y scan my Tesla battery size

[Shnor77]

Learned a lot here. Thanks

I am seeing 82.1kWh "when new" on my March 2021 MY LR through the Scan My Tesla app.

Just a regular AWD, not performance? What is your VIN?

That is correct. Took possession of the car (7 seater) 3/30, VIN 146,XXX

Fascinating. I'm taking delivery of a Y soon (2-5 weeks....) I'll report here on the pack size. I'd like to hear other recent VINs too. Maybe you're just lucky and have a AWD+ Model Y. My 2018 Model 3 is only reporting 66kWh recently (I need to attempt a calibration routine) so if my Y has 82kWh the highway range between the two should be very close to the same.

Here are my calculations. Correct me if I'm wrong.

233Wh/mi * 185 Projected / 0.55% = 78.37kWh?

Picked up 3/30 with VIN 161xxx MYLR.

 

[ElmieY]

Mine came out to 78.6kWh
Picked up March 27th vin 144xxx

How did you come across that number?

Calculations are above. Open the energy screen and take avg kWh * estimated / battery percentage

 

[secprotocol]

So if we calculated 78kWh, is it safe to say we have the 82 kWh battery? I think the standard was 75 kWh?

 

[Langzaiguy]

I just calcuated 78kWh as well. I guess that is 1kWh less than what Scan My Tesla is saying. SMT is also saying there is an additional 3.6kWh buffer.

Very interesting. So it's sounding like the LRs have the 82kWh pack!

Langzaiguy, what happens if you do the math with SMT's more accurate battery percentage that includes a decimal?

 

[whisperingshad]

Supercharged to full for a trip and it showed range of 326 miles.

 

[ratsbew]

Can you do some quick math on the battery capacity? From the energy screen, take your average Wh/mile and multiply it by the current projected range.

What Wh/mile are you getting on your road trip?

Good idea, but I didn't see any change in the 78kwh total. Here's what SMT was saying this morning as the energy screen showed 301wh/mi and 215mi of range.

I'll do on trip back, forgot to take pic when I parked..
Honestly though, I don't think it's an accurate way to test since only shows last 30 miles

Comes out to 79kWh even. Using your 326 mile rated range, you'd have to average 242Wh/mile. Mind sharing what your average consumption was?

NO idea how to pull that up on here....fyi that trip was at 80 with autopilot and steering on.

 

[ratsbew]

You'd have to reset a trip counter to get that data.
