S85 Battery Degradation

[Piney999]

I know this thread has been done before, but I am looking for some fresh data. For the S85 folks out there, whats your milage, and whats your 90% rated miles. I am at 101,000 miles and my 90% is 203 rated miles... That seems too low, but I want some more data points. I still love the car!! Appreciate the help! Cheers!!

That is very low. Was there a sudden drop that you can remember?

S85D, 39K miles, 90% = 236

I don't generally use 90%; I always use 80%, but I can extrapolate a little bit.
Mine is a March 2014 S85. It has 54,700 miles on it. At 80%, it's about 205-206 miles most days. So that would be about 230 for 90% if I calculate the ratio.

Yes, I lost 20 rated miles about a year ago, and the service center chalked it up to new software, but don't buy it. Im going to have my car serviced soon, so I want to be armed with as much information as possible before I bring it up again to service. That is my thoughts behind this thread.

2015 S 85, 43k miles, 90% charge is 237 miles rated

2015 Model S 85D, 30k miles, 242 rated

12/2014 Build with 51K miles - 234 rated miles @90%, 257 miles @100%

 

[gmontem]

2012 Model S 85, 80k miles, ~222 miles rated @ 90% state of charge.

I am not sure if this is a coincidence: I noticed more reported miles at 90% SOC during the times I happened to charge my car when the HVAC was in range mode.

2013 Model S 85, 105k miles, 223-224 rated miles @ 90%

s85 2014 83k miles 100% is 252-254miles depending on season and driving style. Battery is D pack

90% 226mi

2013 S85, B-pack, 55k miles: 90% = 231 miles

2012 original A battery - S85 - 183k miles - 90% 211 to 213,, 100% 235-238.

OP, I would charge to 100 percent three days in a row, and ideally drain to less than 20 percent before or in between to get proper battery balancing. Try it out.

I get 228 @ 90% on my mid 2013 S85--FWIW I do very little supercharging, almost never charge above 90%, and almost never go below 20%. I have a B pack. Never replaced. About 53k miles.

From the collective data so far, it seems like your car is about 25-30 miles low, which is about 8-10kWhs that is missing. I would not think that's OK.

Document everything, just in case you decide to take action(s).

I am in that process right now with my S60.

Good luck.

So, I brought it up to the service center again, and was immediately dismissed and told "well, degradation is normal in electric cars" Like I'm a total moron. Without even knowing who I was, or looking up my VIN, they just said, "Ya, thats normal"...... Which I am convinced it is not. How do I push the issue? Is there a question I need to ask, or some data I need them to pull to verify it? I feel a little in the dark on this, where I know something is wrong, but I have no idea how to prove it. Thoughts appreciated!

Two words, executive escalation.

submit it from your my tesla account, may take a week but it will go to the top and then come down to get looked at and fixed if needed.

08/2013. I consistently get 234-238 miles at 90% and 254 - 260 miles at 100% charge.
