Model X 90kWh battery pack degradation

[bionichomer]

Did a full charge at work today and got 232mi. So that means I have about 7% degradation.

That looks correct. My 2016 X 90D charged to 215mi at 90% today. That puts me at 215/.9 = 239mi compared to the original 257. I'm at 7% degradation.

The chart you show; is that for 90kWh packs only, or for all reporting vehicles? Because that makes quite a difference. I'm willing to bet 90Ds are heavily represented below the fitted curve.

I found the chart linked earlier in this thread. Not sure which packs they were but just assumed it was for 90 packs.

X 90D March 2016 build, VIN 1500's, 27000 miles. 80% charge = 200 miles; therefore 100% charge should be around 250 miles. So about 3% degradation. I haven't done many full charges/discharges and very rarely supercharge (a few times per year).

That looks much better than mine but happy for you. My car is August '16 build.

X90 D, Built in March 2016. VIN is in the 1800s. 63,000 miles. My current 90% charge is 206. TeslaFi is reporting an estimated 100% charge of 229 which represents a 10.9% degradation. I have rarely charged to 100% and hardly ever use superchargers.

Did a 100% charge coming back from a trip and got 237mi so now degradation calculation is 5.2%. That makes me feel a little better. Maybe if I keep charging to 100% i'll end up at 0% degradation

November 2016 build, 71500 km.
394 km at 100% vs 414 rated.
(394/414=0.951) -> 4.9% degradation so far.

X90D 29,000 miles

100% 252 miles.

I measured a 2016 Model X 90 yesterday. It had only 30k miles and almost 10% degradation.

My 90D Model S at 100% is currently reporting back at via BMS ~75kWh capacity and full charge is 258 out of original 294 at delivery. Car now has 77,000 miles on it. ~ Jan 2016 build.

If not allowed, mods please delete. Here is my data record. I do this every 1000 miles.

My 90d 2/16 build almost identical 54k miles 100% 261 miles

You guys with your Model S reports freak me out every time, since this is the Model X forum. 100% 261 miles?!!! Wow!

Uggh- I charge to 90% SOC and get 199 miles. @100% SOC I get 220 miles - it has 35k miles on it and it’s not like I have extremely cold weather in the SF Bay Area

Forgot to mention 4/16 build - I find this excessive degradation

May 2017 build X90D. 24k miles, 100% is 257, 90% abou 234. It was originally 263 at 100%. I don’t consider that aweful for nearly 2 years.

That is a lot of degradation. In the cold climates these degradation numbers become significant when driving around for the day. Also when traveling across the country...

I really wish we could upgrade from the 90 pack (I know its not 90kWh) to the 100 pack.

I may be doing just that. Except I'll be getting a new Model X body on top of the pack as well, and taking the depreciation loss.

The new pricing is enticing. It includes Subzero for deicing, and the 90 pack isn't sufficing. Some things aren't worth sacrificing.

394 km at 100% vs 414 rated.
(394/414=0.951) -> 4.9% degradation so far.

FWIW my 2016 X90D is in the same ballpark as your's. So around 4-5% off the original in close to 3 years. Also GTA.

Turns out my battery had some issues and is now being replaced- kudos to the engineering team for doing the diagnostic and informing my local service center.
