    Wiki Sudden Loss Of Range With 2019.16.x Software

    The EPA number of 295 is including losses from the charger when going from AC to DC. i.e. they calculate your utility will bill you. Each car has an internal value for the rated multiplier. For example, on my 85D, this is what the car uses. VAPI_ratedWattHourPerMile,290.000 --> i.e...

    Tesla's 85 kWh rating needs an asterisk (up to 81 kWh, with up to ~77 kWh usable)

    Should be pretty straightforward.... Did a few of those tests on my 85D when I got it back in 2015... Was trying to get over 80kWh (it was a 85kWh after all right :P ). Closest I could get (without being stranded) was 74-75kWh since last charge... and extrapolating for the %left inthe...

    Sudden Unexpected Acceleration today

    Except when the brakes are iced over of glazed with water... then the powertrain will overpower the brakes (definitely not what happened here!) Had a few surprises last winter... disks were covered something that made the first 1-2sec of braking completely ineffective. I was also wearing...

    Yeah, got the same email.. worst yet, the title (in French) made it sound like they had a new supercharge in Quebec city! "Une nouvelle station de Superchargement est inaugurée à Québec" When we say "à Québec" it means in Québec City... when we want to say Quebec, the province, we use "au...

    Mine? Nothing. They basically said I was on my own and wouldn't cover anything. They gave me the number of the authorized body shop in my area and sent me away. Decided to just use touch-up paint and leave everything as-is...

    Tesla S non-compliant with lighting regulations in USA

    It's all about your butt ;) No kidding. You want to leave the lights on? Get out of the car, lifting your butt will turn the car off. Now reach in without resting your hand on the seat and turn the lights on... close the door and voila. Lights on while car is off and you are out. I do that...

    Wait, you have a 2013 60kWh model?! It probably doesn't have the required hardware to do DC charging.... have you confirmed? Early 60kWh models did not come with it.

    Near annual replacement of 12V battery is typical according to Tesla Service Tech

    I'm not sure exactly what changed. Capacity changed for sure but I think that it's still sealed lead acid. As for the config, it's a config on the gateway like everything else. I'll see if I can dig out the info.

    Near annual replacement of 12V battery is typical according to Tesla Service Tech

    Just one thing to be aware of : Tesla chaned the type of battery at one point... and if you replace the old one with the new model, it requires a configuration change in the car... and this can only be done by them. I'm not sure which one is new or old (model number)... but someone could...

    Supercharger - Laval, QC

    Good point.. probably a lot easier to install since wires are smaller from the cabinet to the stalls. Might explain the Laval install.. the cabinets are pretty far away from the stalls themselves.. especially the one on the north side. Running wires for 135kW to each stall was probably super...

    Possessed charging port

    When they started installing the new charge port. The exterior of the body is the same. It's the sheet metal INSIDE, around the charge port that is different. Can't find picture right now but the mount points for the charge port aren't the same...

    Tesla's 85 kWh rating needs an asterisk (up to 81 kWh, with up to ~77 kWh usable)

    Yeah.. you guys with 90 packs aren't lucky at all. Worst than 85 degradation. weird throttling at superchargers, etc.

    Tesla's 85 kWh rating needs an asterisk (up to 81 kWh, with up to ~77 kWh usable)

    You don't need to do a ride with AC off and all. Just charge to 100%.. and drive at around 65mph. The idea is to try to avoid pulling more than 50-60kW as you'll lose a lot of power to the internal resistance of the pack (waste heat). Make sure you reset your trip meter and do it in one go...

    Tesla's 85 kWh rating needs an asterisk (up to 81 kWh, with up to ~77 kWh usable)

    That's a good question. -The values coming from the car, I have no idea. You would assume the car's own BMS would be within 0.5% or so. (no clues really.. guesstimate) -The values coming from my AC readings are within 0.5%. I'd have to check the certification & calibration paper and cross...

    Tesla's 85 kWh rating needs an asterisk (up to 81 kWh, with up to ~77 kWh usable)

    Life is so weird... I just received a notification that one of the channel I'm following on Youture put out a new video... "Why You Can't Win an Internet Argument - If you're still in an internet argument that started weeks ago, you're probably better off just letting it go." Perfect timing :D

    Tesla's 85 kWh rating needs an asterisk (up to 81 kWh, with up to ~77 kWh usable)

    I agree with that. It's just that in both case, I would find it misleading. That's my thought too. Manufacturer provided number. I've yet to find an actual measured Ah value (not even kWh) in any EPA documents for the Model S.

    Tesla's 85 kWh rating needs an asterisk (up to 81 kWh, with up to ~77 kWh usable)

    I believe that the usable capacity on a "85" Tesla is around 77 or 78kWh. I'm basing this info on the following (using miles for simplicity) The in-car value "VAPI_ratedWattHourPerMile", on a 85D is 290 wh/mi and it's rated range is 270miles. 270 * 290 = 78.3kWh Driving around, you'll end up...

    Tesla's 85 kWh rating needs an asterisk (up to 81 kWh, with up to ~77 kWh usable)

    Ok so we agree that the 245 is given by Tesla. 350x245 = 85.75kWh. That means that Tesla is providing a Ah value that matches the sticker on the battery. 85kWh. No surprises here. May I quote you : Let's recap what we have as numbers for the S (using EPA instead of testing facility for...

    Tesla's 85 kWh rating needs an asterisk (up to 81 kWh, with up to ~77 kWh usable)

    I know. What I'm pointing out is that this value, "245" has been in ALL certifications documents from the SAE since 2012. In all model years.. even 2017 when the 85kWh pack isn't available anymore. It also looks weird. "245". not "244.12" or "245.79".... just 245. Let's take the data you...
  38. llavalle

    Tesla's 85 kWh rating needs an asterisk (up to 81 kWh, with up to ~77 kWh usable)

    That's the thing.. that 245 value doesn't have any real source. All of the EPA's document, including the one I posted above (MY2017, no 85kWh battery) have 245... Can you provide me with a document that states how the 245 came to exists?
  39. llavalle

    Tesla's 85 kWh rating needs an asterisk (up to 81 kWh, with up to ~77 kWh usable)

    Lol, no need to attack me personally. I was saying that while you did post all of the information for model 3 (integrated values and so on)... you never posted any document that had those value for the Model S. Just link me the source of your data for the model S in 2013! Meanwhile, I managed...

    Tesla's 85 kWh rating needs an asterisk (up to 81 kWh, with up to ~77 kWh usable)

    Fair enough, that's for the model 3. Do you have the exact same values for the S? The "Charge depleting test" This is what you posted : Unless I can't read... I don't see any integrated Amp-hours value... All I see is average system voltage (350) and that's it. In fact Integrated...

    Tesla's 85 kWh rating needs an asterisk (up to 81 kWh, with up to ~77 kWh usable)

    Well, they do seem to actually install a shunt on the HV loop (see page 5).... ! I was wrong about that one. That's actually pretty surprising ;) Yes, this could also be a factor here (might explain the initial value from the BMS). The same rationale applies though.. if you lose 3.2% of...
  42. llavalle

    Tesla's 85 kWh rating needs an asterisk (up to 81 kWh, with up to ~77 kWh usable)

    Humm, what? The value is 95kWh from the wall... and in infers 85kWh from the pack. You really think the EPA installs a shunt on the HV loop and measures power coming out of the battery?
  43. llavalle

    Tesla's 85 kWh rating needs an asterisk (up to 81 kWh, with up to ~77 kWh usable)

    I would like to also point out that this 85.75kWh value is labeled as a "calculated capacity".. not measured... As I stated in my first reply.. the EPA's calculation is meant to convey the amount of electricity the car will pull from the wall to perform a set of simulated driving conditions...

    Tesla's 85 kWh rating needs an asterisk (up to 81 kWh, with up to ~77 kWh usable)

    I'm dismissing data from a car in which the BMS hasn't seen a full battery cycle. That is battery 101. It has nothing to do with any of my conclusions. As for the 81-82, I'd have to dig is some of my early CAN logs but IIRC, BMS reported 77.7kWh of usable capacity + 4kWh buffer on my 85D that...

    Tesla's 85 kWh rating needs an asterisk (up to 81 kWh, with up to ~77 kWh usable)

    Also.. case in point : The software limited 60 (75 pack) had an actual usable capacity of 60kWh... no buffer or anything. The 85 has a 4kWh buffer.. so supposed to have 81kWh usable. why so? Why would a 60 have 60 usable and a 85 have 81 usable (not even counting the 81 is probably 78 or 79...

    Tesla's 85 kWh rating needs an asterisk (up to 81 kWh, with up to ~77 kWh usable)

    I don't know for sure. The original design intention was to have a 40, 60 and 85. Then they probably realized they could deliver the promised range for less than 85kWh or maybe the module design added up to 82 or a lower value and they decided to stick with 85 for some marketing purposes. Why...

    Tesla's 85 kWh rating needs an asterisk (up to 81 kWh, with up to ~77 kWh usable)

    And I bet a bunch of those "90" labeled pack had very close or less capacity than some "85" packs... those 90 pack cell don't seem to have a shallow degradation curve like the 85 ones
  48. llavalle

    Tesla's 85 kWh rating needs an asterisk (up to 81 kWh, with up to ~77 kWh usable)

    Every single time the battery is drained / charged, the BMS adjusts this value according to what it can sense : current that went though its shunt, soc, etc. Using an algorithm that we don't have access to, it tries to predict the available capacity according to the current voltage of the...

    Tesla's 85 kWh rating needs an asterisk (up to 81 kWh, with up to ~77 kWh usable)

    You realized the first thing that guy said is "Can bus data from a new 85D with only 300km on odo.". 300km = not a single cycle on the cell. AKA.. the BMS has no clue.. and probably assumes a static value.. a default value. We can't know cause we don't have access to the BMS code but it must...
