Luckily 50% is below the 'bad' calendar Aging jumps of both NCA, NMC and LFP. And if I park my Tesla at 50% it will be in 30% in less than three weeks :)

Owners with Ludicrous and P models will have a functionality loss at low SoC, namely performance :-( For my car it is only Range Inconvenience. My Low Power Model S 70 D 2015.10 has same acceleration at most SoC's. As seen here, it has same 275 kW - 285 kW and 0-100 kmph in approx 5,2 Secs, at...

I totally agree,! My 72% Max is when doing long trips and when super charging. My daily commute DOD is centered around 40% and planned so that all longer idle periods happens at less than 55% SoC (50% preferred). The very majority of my capacity loss is likely Calendar Aging. You can see it...

Hmmmm, I have read many different stories about how to balance Tesla (A: Charge to above 93%, now Blead Resistor CMOS (switches) will be turned on with timers, to blead off current from Bricks with too high voltage, which will take days. B: It Balances by itself all the time etc. My current...

I came to this thread because I searched wide for 'ScanMyTesla Export to CSV' :-) I think the thread was intersting, and is left with the impression that: A: The PTC Heater is occasionally on in a chopped mode B: The watt hours 'wasted' is normally small C: I personally think it is natural...

I think I know why, my Nominal Capacity is off! Before two longer trips, I have balanced my Bricks by charging slowly for 10 hours in the Balanibg window of 80% -100% SoC. Each balancing only improved ImBalance by approx 2 mV (According to FB/Recell, the blead resistors only blead 100 mA, so it...

According to Jeff Dahn (Li-Ion professor and expert at Dalhousie University, with a team of students and PHDs that are Tesla Consultants) the way to not cause excessive increase in Battery Internal Resistance for NMC is to stay below 4,07V :) (As my Model S 70D has Panasonic NCA cells, I try to...

I can confirm - if you do not have a P or Ludicrous model, which requires higher SoC and elevated temperature, but - say - a standard Model S 70D, then the power delivered seems controlled by software to match the specs for the car at many different SoC. (SMT occasionally reports that my...

That was a good deal :) And assuming they software limited it inth top to the original 77,5 kWh in a Model S 85, your future battery degradaion should be VERY small. Here is my range from new, when I Rarely charged it above 70%::

I think above calculation was way off! Having slept on the issue, I have come to the conclusion that the voltage ImBalance from the CAC ImBalance should ONLY be 20 mV at 100% SoC :-( 0-100% SoC wil produce (approx) 3,0 - 4,2 Volt increase on the brick(s) with the lowest Ah capacity. That means...

I looked up the Jason reported numbers and they were: Total Usable Original 60 61 58,5 85/P85/85D/P85D 81,5 77,5 90D/P90D 85,8 81,8 Original 70 71,2 68,8 75/75D 75 72,6 Software limited 60/60D 75 62,4 Software limited 70/70D 75 65,9 Interesting that I now have...

Hmmm, According to Jason, a Model S 70 2015 had 71.2 kWh Brutto and 68.8 kWh Netto - that is why I entered 68.8 kWh as Initial TeslaMate Battery Health page allows one to specify initial capacity. If one does not do that, the Page will use whatever maximum Capacity is hidden in the Teslamate...

Thanks for the replies! I know a little more now. I had a long trip planned for thursday (2 x 105 km at Danish Highway speeds of up to 130 kmph :)) so I decided to test my theory that the voltage imBalance was BMS Intentional and to correct CAC ImBalance. So I charged to 100% (third time in...

I updated my 2015.10 Model S 70D MCU1 to 2022.8.10.17 on March 3 - a few days later, when we turned on the Infotainment, we noticed that both front door speakers had no sound. I performed a Deep Reset (Wheel Config) and still no sound. Confirmed that the Center speaker, which is served by the...

I own an old Model S 2015.10 and have long assumed that even my old car balances 'all the time' but only when needed. My assumption was based on this my ImBalance Versus SoC graph from SMT data: The minimum ImBalance (of 20 mV) is on the GEOMEAN of my SoC window :-) One could wonder, why...
