75D battery degradation

Seems to be in line with the degradation on the 75 packs. Around 10% at 50K miles. It's supposed to level off more or less at this point.

That's pretty close to my experience. I was at 10% range loss around 50k, and have since risen to ~13% at 110k - 217 miles at 100% on a RWD S75 (249 when new).

Just for the interest. My loaner car from SC is a 75D 2018. 291mi at almost 100%. The battery pack has 75D 350VDC label. The milage checks out since i have been driving it for a few days while waiting for my repair.

An S, but staring solidly at 10% degradation at exactly 50K miles. Charges to 233 miles at 100%. Periodically run the pack down to the low single digits on long runs out west or in very bad headwind scenarios. My BMS is solid on reporting.

For me this car is a 350 mile radius car max driving in a single day; anything more is beyond frustrating...

I agree with your frustration, my S75 range is 225. However, when I get frustrated I run some sample trips in Abetterrouteplanner with newer cars and multiply the time savings by $500/hr as my personal value of an hour. I would have to take a lot more trips than I do to justify a new Model S.

Aug 2017 build S75D A.P.2.0, MCU1, Enhanced AP and winter option. 26500 miles. Lifetime range at 233 miles.

Happy to find this thread. I have a 10/16 build MS RWD 60 (Software limited pack).
192,000 miles later my 100% range is 184. It was 216 at new. I drive 100 miles each way for work daily. Usually supercharge for a bit on lunch or on my way home. Max SuC rate is 81kW now. Happy to see my car falls right in line with everyone else. I'm guessing my unlocked 100% value would be right around 213/214 if its locked to about 86%

2016 RWD 60 was rated at 210 new. Pretty sure mine was delivered with 208 showing on the dial, I'd have to go back and look. Maybe you had a ringer battery to start with. ;)

Interesting your supercharging rate is so low - when the car was new it topped off at 100kw, now I see in the 130s ever so briefly with a warm low battery.

I only hit 100kW ONCE, but I literally use the same supercharger all the time. Just recently started stopping at a new V3 occasionally depending on traffic. Honestly, when people ask about the car, it's the only negative thing I can say. I wasn't aware they were going to slowly taper my SuC speed. Other than that, I have been very happy. Literally only 4 sets of tires and an increase on my electricity bill of about $80 per month. This will be the first car I drive until "the wheels fall off" haha! (knock on wood, that it doesn't happen anytime soon)

Software limited pack have available around 87% of full 75 battery. But if you have 60 battery you can charge it to 100% with no worries.
But to be hones still the best option is to unlock full pack.

A few weeks ago i drove 347km (215miles) with 61,3kW used with one charge, had 2% left of charge at that point. Lost a few % of battery during th day when it was parked. Have a 75D and has 170k (105k miles) on the battery.

Scan My Tesla said a few months ago that the pack has nominal full pack of 67.9kWh and useable of 63.9kWh. So seems to add up.

Thanks for posting - think you're the highest mileage report on the thread (?)

Do you recall when mileage-wise you saw the Supercharging rate being capped down?

I have not seen it myself (S75D with ~105k); SuC rates use to top out at 96kW, then approached 116kW, and have remained there. I do not consider myself a heavy SC user, maybe a few times a month on average. Charge to the mid 70's for daily driving.

Tesla nerfs the 75kWh batteries once the amount of DC charging reaches a certain point, I do not remember what that is. I think that reduces the charge limit on the battery to 84kw or something. It has nothing to do with mileage.
