What's your 90%?

[Markk993]

P85+ 2014 with about 24k in mileage...

90% 233 (sometimes 234)
100% (265 both times i did !00%)

Feeling really good about that compared to others here....

After 15 months of ownership, my P90D, yet once again, shows 234 Rated Miles at 90%.
19,456 miles on the odometer.
When new on 3/3/16 it was 241.
So still about 3% degradation.
Still charging to only to 60% on a daily use basis.
I am on firmware 17.24.28

2016 prefacelift MS 70D, 30K miles, charge to 90% every day, 213 RM down from 216 when new. 235 RM @ 100%.

 

[RobinF]

25,000 miles on my 2014 P85D : 90% = 222 miles. Hasn't really changed much since new.

I've got 36K on my 2016 Model S 75 RWD. My 90% is 207 and my 100% is 231. (I've ranged charged twice in the last two weeks to see if magical BMS adjustments would occur.) I'm not sure if I should be concerned because these numbers may indicate more degradation than I expected. My car was at a body shop for 16 weeks without being charged (when I picked it up it was at 47%) but I have no real reason to believe this 4 month absence of charging has anything to do with my lower-than-expected (for me) numbers.

IMHO, ideal numbers are better for indicating battery degradation than rated miles because the ideal miles aren't messed with every couple of releases (or at least they don't seem to be). Charging to 93% or more activates the balancing circuits, but they can take quite a while to do their thing. (Doesn't matter what you charge to once they are activated, they stay activated until complete.) However, this will only make a difference if your pack was out of balance to start with.

Best practice is to notify the Service Centre so that they can look at the car and have it on record (be sure you get and keep a copy of the work they do).

I traded in my 2015 70D last week (vin 87598), my 90% stayed at 210 miles for 2 years and 33k miles. I had only used the superchargers ~8 times, and charged it to 90% every night via the wall charger limited to 30amps.

Something weird happened with my P90D. My 90% has settled in at 241 for a while now (244 when new). I took the car down to 3% yesterday and this morning 90% is 246. So my magic battery now has more rated range than when new. I suspect a little wonkiness with the algorithm rather than actual capacity that high. Will be interesting to see what it settles back down to.

Some figures with almost no lost of range (at 90%) after 16 months and 18'000 km.

 

[vesder21]

just picked up a 2013 P85 CPO and its charging to 222 miles @ 90%

 

[supratachophobia]

2016 90D 245 @ 90%

That's about where mine is, which is also a 2013 P85 w/ 65k miles. How many miles do you have?

71K miles now, in the current warm summer months I'm still getting 226/227. Late '13 P85+

2014 S85. 75,000 miles. Fluctuates between 223-225.

 

[mrjedistud]

2013 P85 with 50,000 miles. Getting 230 at 90%, but it does go down in the colder months, assuming to 228 @90%.

[Model S M.D.]

P100DL, 9K miles:

281.37 @90% (~284 on delivery day)

It will be interesting to see how quickly you get that initial drop, and then settle into a more or less steady 90%.

Sept 2013 P85+ with 69k gets me 229/231 at 90%. Wife's Sept 2013 85 with 44k gets 232/235.

As someone with roughly the same mileage and stats (238 at 90%, 263 at 100%) on a 2014 P85 with rev. D battery, I'm curious about something: how often do you plug your car in?

I plug in maybe twice a week, when needed. Yes, I know we've been told that "a plugged-in Tesla is a happy Tesla," but I normally don't leave the car plugged in for longer than it takes to charge. My battery shows very little degradation (when new, it was 240 at 90% and 265 at 100%), and I'm still on my original 12V battery after 3 years.

Could it be that many short charging cycles are actually not as beneficial as fewer overall cycles, and/or avoiding the low end of the battery's range? (I don't know; it's something I'm wondering based on my experience.) Maybe there's a behavioral component, or maybe some people just get luckier with their chemistry.
