How do you know so accurately when the calibration happened? Is that shown somewhere?

Thank you, I appreciate your support! Are you referring to this method: https://teslamotorsclub.com/tmc/threads/tesla-battery-management-system-bms-calibration.327886/ I had the understanding that when I did the 90%->7% discharge during the course of 5 days, letting it sleep for hours between...

Since my last post a couple of things happened, some of them are a bit concerning. The next day after a 309km drive I charged to 100%, then the teslafi "Estimated Battery Range at 100%" increased a bit to 464km. (earlier it was fluctuatin aroung 470, in the last couple of week it is more around...

For now I decided to not focus so much on determining the real SOH better than the BMS does, but to help the BMS calibrate itself, and leave it to determine the SOH (and maybe help it to balance). I started from 90% SoC and used the car through multiple days, leaving the car to "rest" for hours...

I charge only to 55% on a daily basis, and although there are multiple different rumors about when a MS FL starts balance, with this charging regime it almost surely won't. I am happy to do the balancing when it is not balanced. Probably I will need to get SMT sooner or later anyway :)

just read that, and understood the main point, its quite a brilliant method to calculate the real capacity even without SMT. Is there maybe some similarly clever solution to estimate whether cell balance is off (without SMT) and its time to perform the balancing voodoo?

How can you perform a 100-0% drive in practice? Just drive until the car stops and then call a trailer? :)

Can you maybe suggest the best thread which gives the most complete view about battery "science" in terms of Tesla BMS, interpreting SMT values, etc,?

Thank you very much for the detailed response! Regarding the above, I have seen multiple, contradicting descriptions, so I am not sure which procedures are currently considered as best practice. -balancing: above 80, 90, 93 or only at 100%? During sleep, idle or charging? -for the BMS to...

I am wondering if there is a common best practice to determine the SOH trend of my car. I think I understand the basic math (as described at Tesla battery degradation and health), also I have Teslafi which provides the famous Battery Report. However in my understanding the result of the battery...

In Hungary, we have a special rate system where households pay an artificially low electricity cost, and in exchange every goods, services etc. are taxed to hell, and we had 35 % inflation in the last two years, etc... Household rate is 0.18Eur, SUC price is 0.44Eur. The electricity provider...

No off-peak period here, flat rate electricity 24/7. I set the off-peak charging in the car just to delay charging to keep it at lower SOC for longer. Then the car itself decides to charge in multiple shorter periods for whatever reason...

May anyone know if battery heating is active during drive if cabin heating is turned off? For short trips I started to use seat heating instead of cabing heating, but I have a feeling like the recuperation limit is not moving up while driving like this. Might be the result of cabin heating being...

I am wondering how Range Mode might affect battery degradation. In my understanding Range Mode switches on battery heating at a lower temperature threshold or battery cooling at a higher temperature threshold, basically letting the battery cycle more outside of the it's ideal temperature range...

This is very useful, thank you very much! Is there any way to switch on passenger seat heating as well somehow? (i can only see shortcut for the driver seat in the app menu)

For very short trips I am looking for a method to conveniently turn on seat and steering wheel heating without turning on cabin heating on a 2018 Model S. Currently what I am doing: -tap on the number in the lower left corner, this turns on cabin heating -tap on the same number again, this...

Thank you very much, it is very useful, showing that my experience is not isolated at all, so pretty much manages my expectations (to near to nothing, kind of :))

As far as I see, these are the relevant information from the local user manual for plain summon: -the car can move maximum 12 meters - a key fob must be "within range" - phone must be connected with bluetooth to the car So for me the critical part appears to be the fob being within range. The...

Does that mean that the "fob only" summon should work as well? As of the user manual, that requires to turn off "require continous press" in the summon settings. However, I don't have that setting at all anywhere. I forgot to mention this is an EU car, so that might be the reason for the...

Are you sure this is the case even for an older car like this 2018 MS?

Maybe I am too optimistic, but since I started to drive a bit more proactively(when I feel that the car is too fast in the exit lane, I don't wait and play the chicken game, but slow down the car manually), I have the feeling that the car started to behave better, it seems that it slows down...

Thank you for your response! If the key fob is not needed, then why do I got the "key fob not detected" error message in the app?

I understand that Smart Summon is Beta and tends to crash into things, so I don't intend to use that. Therefor this question is considered with plain summon. When I try to use Summon on my 2018 MS, the app gives back the "key fob not detected" and nothing else happens. I have even replaced the...

Somewhere I read that the speed limits TACC/Autosteer uses come from telemetry data of other Teslas, so basicaly the speed is determined by how other Tesla drivers drive in an area. I thought that it might be the case that in our area there isn't a large crowd of Teslas, and maybe those 3-4...

I am happy you mentioned the lack of any sound and light signals when the AP apparently acts in a "reactive way". So if we assume that in my case the too late and too shy speed decreases at curves are because of reactive driving by the AP (instead of driving proactively, because I haven't paid...

Is there any specific reason for that? I am using the off-peak charging for two reasons: - keep the SoC lower for longer, to minimize calendar aging(I charge to 55% on weekdays for a 20% commute, and to 90% on weekends to be prepared for any unplanned travel) -hope to have the battery somewhat...

As far as I see in the app, off-peak charging and scheduled charging are mutually exclusive. So I use scheduled preconditioning and off-peak charging. (this morning was special, I set the scheduled preconditioning departure time to a too late time accidentally, so I started the climate...

Until now I tried +10%, +10km/h, +5km/h, same results. I will try 0%, thank you for the hint! In my 2018 MS unfortunately the speed cannot be changed with the scroll wheel, but by tapping the AP stalk, 5km/h tap, which is not convenient if you need to slow down from 130 to 100, etc.

As a comparison, my 2018 MS charged this morning for 4 hours and 10 minutes continously with 5kW, then before it reached the charge limit, I manually switched on the climate in the app, and the car started to perform battery preheating. So apparently no extra heat in the battery to spare. At -...

Does heatpump always come with octovalve and all the niceness you mentioned, or are there different levels, like "heatpump only" and "heatpump+octovalve"?

At least in the case of changing the lane to the off-ramp, that must be a supported feature on my car, because the car instructs me to use the turn signal to initiate the automatic lane change. And when I comply and tap the turn signal, then my passengers got the near death experience of an...

Navigate on Autopilot is Beta. The primary aim of my question is that I would like to know if my experience matches the experience of other users or I am doing/understand something incorrectly, or my car might be broken.

Ok, I think I got your point, so the car is slowing down a little to make the crash less severe, which was caused by the driver in the first place. What contradicts this, is that in some rare cases it does its job quite well: "Or at the end of the highway - where it ends in a 270 degree turn...

Also, lane changes are quite interesting with Navigate on Autopilot. When the car signals the potential lane change into the passing lane, then I tap the turn signal, slightly move the steering wheel(as instructed on screen), then the car nicely and slowly changes the lane. Maybe even too...

But it does adjust the speed, that's what makes it unpredictable. If it would just go with a fix speed only changed because a car in front, that would make it a predictable, normal distance keeping cruise control. But this is not the case, it is changing the speed, but unpredictably

I have EAP, which in my understanding includes navigate on autopilot, highway ramp to ramp Autopilot. So when I change from one highway to another through a ramp, I have one blue line on the screen, in the middle of the lane, and not two blue lines at the edges of the lane.

This is very interesting, thank you very much! I use a 2018 Model S, no heatpump, so it seems that the heatpump makes a huge difference. Actually I use scheduled charging with 5kw, this makes the car to charge during the night in multiple session, each lasting for approx. 40-50 minutes...

I experience the same with a Model S 2018 EAP AP2.5 which was imported from the Netherlands to Hungary. It is also choosing the speed very sporty on turns and highway ramps, most of the time I am not brave enough to let the car go into the curve with its selected speed, so I take over and...

So I am quite new to the Tesla experience (1 month, 2500km with a 2018 Model S EAP AP2.5), but I can't get my head around how Autosteering selects speed, and how much I can trust or use it. Is there anywhere a good description of it? The user manual is not very detailed on this topic. What I...

I am not so sure how small that increase in the bill is. For last month my car reports an average consumption of 240Wh/km, while based on the energy meter connected the EVSE the real gross consumption is 350Wh/km. That is a huge difference, and I think it is mostly caused by preheating

I am not so sure when it makes sense actually. On a long drive it will heat up anyway. If driving cold is bad for the battery, then it will be bad for it both on short and long drives. So if driving cold is not bad for the battery, then the only reason to preheat is comfort(warm cabin), and...

As an example, this morning in 6 C ambient temperature I did a preconditioning for 3.24 kWh, then made a 3.74 km drive for which teslafi reported 1.18 kWh consumption. So the overall consumption for this short trip was (3.24 + 1.18)/3.74 = 1180 Wh/km. That is why I am wondering if...

As a new Tesla owner I am wondering about scheduled pre-heating of the battery. I understand that with a cold battery, regenerative breaking and probably acceleration is limited. What I don't know is how driving with cold battery influences the long term battery degradation? (in my daily 40km...

How do you get the battery temperature in HA? (I cannot find this myself, although I am trying with a Model S with "Tesla Custom Integration")
