I also just bought a March 2017 75D and my first full charge at home stopped at 245 miles today 4/2/21I have a March 2017 75d build and my 100% is 245 with 23,140 miles.

I have almost 90k miles on my '16 75D and my 100% is in the 245-248 range.
08/18 build, 17k miles. Second owner.
214 @ 90%
237 @ 100%
I was supercharging today and it was so slow. My battery level was 76% and charging speed was 34 kw. Is that normal?
Also is my battery degradation at 237/259 = 8%?
I charge to 90% virtually every day.Wow. I have way less miles and also way less range! Dec 2016 here. What do you set your regular charge at? I usually charge to 50 or 60%. 80% if I'm at an SC. 100% for me is 222 miles.
Admittedly this is my first full day of serious research but it's been hard to find confirmation of this information.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.
Used to be for all batteries but thankfully it appears Tesla has removed this charging limit in one of the firmware updates over the last 6 months.Admittedly this is my first full day of serious research but it's been hard to find confirmation of this information.
Is this behavior specific to the 75kWh batteries? I've been to the 85kWh chargegate threads. I'm curious if this is the same underlying behavior or not. I wouldn't be surprised if Tesla makes it impossible to know for sure how much DC charging has accumulated on the pack, but at least for the duration that we own the vehicle we can try to estimate how many we're racking up...
Interesting. I haven't read about that either! If I understand what you're saying, chargergate/batterygate was introduced by Tesla in 2019 and then resolved by Tesla in late 2020?Used to be for all batteries but thankfully it appears Tesla has removed this charging limit in one of the firmware updates over the last 6 months.

Supercharging is probably harder on a battery than slow charging.
With small battery cars, such as my S-60, greater degradation than 12% is quite common, from user reports I've seen. My hypothesis is that the battery gets worked harder since it is necessary to charge higher and discharge lower on road trips. If using the car for local driving only, between 20% and 80%, I would expect reduced degradation. More than two thirds of my miles are from long road trips, as opposed to local driving.I've seen charts that show only rare cases where the Tesla batteries drop below 12% loss in under 8 years. Also, the data shows there is no difference between Supercharging and Level 2 charging as long as your battery temperature management is working properly. What ruins the range on a Tesla battery is discharging most of the time to below 10% SOC and charging to 100% often and letting the car sit at 100%. If you charge your Tesla 75% of the capacity it should last for 800 to 1000 charge cycles before losing 30% of rated capacity.
I believe Tesla is overly cautious with their battery management taper curves. You only get a few seconds at those really high power rates. There are other EV's out that allow flat higher power for 80% of the battery and I believe if people take advantage of that their batteries will lose quite a bit of range in a couple years. With 8 Year 100,000 + mile warranty, these car companies may be sorry.
