High Mileage Model S/X Owners and Battery Degradation in Australia

[BCTS]

Good Evening:
Just wanted to see how the local community is fairing with Older Model S/X and Battery Loss over time.
My 2015 Model S P90DL is at 199,000km now, and my Battery is down to around 71.5kwh Capacity (67.5 Usable).

Basically at around 16% or so Battery Loss over that time period.
Battery itself seems in fairly good health with very small differences between Cells etc... so that's a positive at least.

God know's how little my effective range would be if I was still running Staggered 21" Wheels and Lower Tyre Pressures.

Model X 75D 2018
177000km
KM new: 325km
KM now: 280km
Works out to be 14% battery degradation
DC Charging: 18,584.44kWh
AC Charging 28,376.60kWh

Model S P85D 2015
155000km
kM new(ish): 394km
kM now: 355km

Note: I didn't start recording (Teslafi) this data until there was 20,815 km already driven. For memory I remember getting about 404km when the car was new so degradation since new closer to 12% degradation

I now keep track of my low voltage battery after a “perfectly fine” battery was found to be using 25% of my high voltage battery per week. Its an overnight test worth doing every now and then.

my 2016 S has only lost a couple of km range, but its also not done a lot of km compared to those above so not a usefull comparison.

This is a timely thread, my 2019 X 100D (105,000km) is in getting a new pack (once they get one in, picking up loaner tomorrow) + 12V battery installed. Apparently some electronics sealed in with the pack has failed so they are replacing the whole thing. Luckily the car shutdown while under the carport and not out on the road somewhere.
While it is a pain, it will give the car a new lease of life and I will make sure to keep track of degradation from new which I didn't do with the old one.

S85 February 2015 312,500 kms
Original 399kms now 350kms

Data taken from tessie app

2014 Model S 85; down 11% from 400km to 356km.
The main annoyance, however, is the pathetic charging rate (even on superchargers).

How far has it driven for that 11% degradation?

How far has it driven for that 11% degradation?

Sorry, I should have mentioned that - 150k km; mainly AC charged but with probably 10 to 20% DC.

 

[Tasdoc]

2017 MS 75D
130,000km
Displayed typical range at 100%:
When new 387km
Now 368km
DC/AC charging ratio about 50/50

 

[MickK]

2015 Model S P85D
73000Km
Not sure when new as im second owner for last 4 years however now 368Km on full charge
Ive probably supercharged less than 10 times in 4 years. rest is AC charging at home.

 

[MickK]

2017 Model X 100D
128,000Km
Currently 390Km
nearly all AC charging.

Not sure km when new as Im second owner but have noticed a decline in battery on every charge in the pas 6 or so months
August 2022 and earlier was on average 420 to 424Km with about 112,000Km on it. according to scan my tesla which o only purchased a few weeks ago i have:-
Nominal full pack 85.5Kw.
DC Charge total 1341Kw
AC Charge Total 43986Kw
Discharge Cycles 489

I have now seen the battery test option in the tesla app and will try this over the weekend. MY Model S is older and doesnt have the option to test in the app, nor the scan my tesla needs a different adapter to fit

I was part of the average mid last year but Teslafi now reports " There are 7 vehicles with charges at your current odometer reading. 7 Vehicles have a higher range. 0 Vehicles have a lower range."

Graph below, note the blue line delcline

Teslafi indicates 345km at 100%, 180k km 2014 S 85.
I might do a BMS cycle/reset and see what it comes back with. Have not done one for ages.

 

[ev.enthusiast]

2016 Model S 85D (one of the last nose cone ones) with 21 inch grey Turbines. 203k KM done. Not sure about the original range when new as I purchased the car used. Charges to 382 KM (typical) at 100% SoC.

 

[aegidius]

2016 S90D here. Bought at 25k km, now at 120k. Dropped about 15km range over that period (420km down to 405 at 100%, but it's a bit variable depending on how the BMS is feeling)
