Model S 70D 2015

[springdaisy82]

I love my 2015 Model S70D, and enjoy the free supercharging. However, I also have a 2018 Model 3 that I bought new, and I have noticed the Model S takes longer to charge.

I have heard that the model S was "nurfed" to charge slower, to protect the battery. Is there a way around that at all? I usually charge at home, but when we go on road trips, it would be really nice to have it charge faster.

I imagine this isn't something that can be changed, or maybe we wouldn't want to anyway?

Apart from arriving at a very low state of charge, I’ve not found a way around the excruciatingly slow supercharging rate

No.

Was on the same boat with MS 85D, there're basically 3 solutions for that: 1) Downgrade the SW to some pre-nerfed version, but that one would have many cons, therefore not recommended.
2) Upgrade the battery to not nerfed 90 or even 100kWh one. I did the 100kWh upgrade and it's absolutely different experience even though it's still not as fast as M3 is.
3) Trade the car for another MS with nit nerfed battery.

I thought the 2015 70D was limited to around 90 kWh charging from the start. My 2016 75 was limited to about 80 kWh when I first got it, then about 2 years later with software updates it started charging around 120 kWh at optimal SOC and handled that until I sold it last year.

The best charging rate today is with the 2021-2023 Model S LR, with a combination of the largest/newest battery having a 250 kWh charging rate, and the most efficient overall S design so far.

Yes, but the price difference will be also significant + maybe @springdaisy82 likes Free SuC too... S 70D should achieve according to ABRP data something around 110kW at 10%SOC and will fall under 100kW at around 20%.
And one small remark - "kWh" is unit representing energy, "kW" is unit representing power, so that's the one you probably meant

I am glad to hear that you were able to upgrade the battery. If and when this one fails, and if the car is still doing fine, I may do that. May I ask how much that cost? And did you do it because of a failed battery?

Yep! Thanks. Wasn't careful enough and I should have been.

Sure, it was roughly 12k€ as for replacement (I didn't get the old one back). The battery was ok, but nerfed, slow charging only till 4,1V...

I understand that all Tesla Model X / S vehicles built starting mid-July 2020 and newer support the fast 250 kW charging rate. If you have a slightly older one, say from May 2020, it should support the 225 kW charging rate. If it's from 2012 - 2019 then the maximum rate is about 120 - 150 kW. That's if you start out Supercharging at a lower state of charge, like 15% and navigate to the Supercharger first so the car can precondition the main battery.
