    Service says $22k for new battery on 2012 Model S

    Weight is a small impact on range compared to everything else. Even if the battery weighs another 500 pounds that's only going to be a couple of percent off the range.

    Repair laws are finicky. If there's an accepted quote and they've started work, they are likely to do it at the contracted price.

    Model X 90kWh battery pack degradation

    The curve on my pack was never bad and it's really flattened out. Looks like my 90% number is finally sticking at 226 this year after bouncing between that and 227 for a while. I can't help but wonder if most all these curves flatten out after doing whatever decay that particular pack goes through.

    FS: OEM 12V Battery - Tesla Model X

    It requires a communication wire that your older X doesn't have. You're better off going with aftermarket LiFePO4.

    How old, by the way? Will an X always have the standby wiring?

    Service says $22k for new battery on 2012 Model S

    I think if there were replacement packs turning out to be awful we would see a ton of threads about it here, and on Reddit, and probably on the usual blogs. The fact that we are not - and that they put a warranty on the replacement pack - suggests to me that they are using good condition packs...

    Service says $22k for new battery on 2012 Model S

    I know this is getting fairly OT for the thread, but this is what makes Sentry feel bonkers to me. It really offers very little practical advantage that I see, effectively becoming very expensive insurance. Some people love it though, and I'll take that it means I get the benefit of people...

    Service says $22k for new battery on 2012 Model S

    Aren't the 350V packs all the smaller capacity ones? The 400V packs would be the 85, 90, 100 packs. 350V packs are 60, 70, 75. Anyway if they give you a quote with a certain part number and then install a different part number, you should be protected by your state repair laws.

    It doesn't have the wiring. Tesla won't modify the wiring on older cars to add it.

    Service says $22k for new battery on 2012 Model S

    Yes, I think we are on the same page there. If they were still putting effort in to optimizing the MCU1 code and were more careful about feature bloat it would likely still work just fine. If anything I bet the biggest constraint is that the system is short on memory.

    Service says $22k for new battery on 2012 Model S

    One of these days I'm going to accept that Tesla has abandoned MCU1 and finally pay for the upgrade.

    Service says $22k for new battery on 2012 Model S

    So far the restrictive bullshit seems to be heading in roughly the right direction. You can at least get some access to Toolbox now, and the parts catalog is online. It would be great if it were cheaper and open, but it's a start. I'm not sure we would have gotten there without the efforts of...

    Service says $22k for new battery on 2012 Model S

    If the packs have 2000 usable cycles in them, that's something like 450k miles. More of a question mark for me is how these packs will look after fifteen years of calendar aging.

    Service says $22k for new battery on 2012 Model S

    I'm curious to see how long some of the cars make it. I just pulled out some 18 year old lithium-ion battery packs that were left dead for at least five years and charged them up the other day. Every one of them took a charge after being woken up, and all but one of the four seem to have decent...

    Service says $22k for new battery on 2012 Model S

    Blowing it up was 100% a stunt. They pointed out that they removed the useful parts, and what was left would have mostly been at least scrap metal.

    Service says $22k for new battery on 2012 Model S

    All of this sounds like an awful idea for Tesla. They're going to spend more doing extra warranty swaps than they will just rebuilding the packs properly. Someone will have done the math and realized that it's better all around to pull the truly marginal bricks out of the stream. It might make...

    Navigate on Autopilot is Useless (2018.42.3)

    I remember those stories. I always wondered how people hit another car while paying attention to the road, and figured they had ceded control to the computer. That's certainly braver than me! I find AP relaxing but only because it means I can look further down the road and spend less time...

    Navigate on Autopilot is Useless (2018.42.3)

    When someone stepped in to the gap it used to be really aggressive about making a new gap. It's been super smooth for the last year or two though, at least in my experience.

    Navigate on Autopilot is Useless (2018.42.3)

    I have found this behavior to be quite consistent. It's actually the reason I stay out of the right lane most of the time on AP, because it's a little too aggressive about getting out of the way of merging traffic. In middle lanes, it clearly has a bit of hysteresis so it doesn't just jam on the...

    Navigate on Autopilot is Useless (2018.42.3)

    In the presentation Andrej gave recently about going to pure vision they showed exactly what sort of data caused phantom braking events. It's bad range finding data coming out of the vision or the radar. Eliminating the radar means they are left with one stack instead of two, so there is less to...

    Navigate on Autopilot is Useless (2018.42.3)

    Hands off the wheel is a long ways away, unless we want to accept more collisions as a result of AP usage of any flavor. Last year I had to do a quick evasive maneuver using AP was to avoid a large chunk of metal in the road. I had enough time to react as it came under the truck in front of me...

    Navigate on Autopilot is Useless (2018.42.3)

    I'm happy to go make a 50 mile drive on AP2. Provided I head south instead of north from here, I expect no issues. If it's north, I know exactly where the issues will be. Unless it's night and raining, then **** AP2 because it will suddenly red hands me for no reason. Okay maybe it's not great.

    News for Model X owners with the dreaded shudder

    We have similar throttle strategies, so Raven must be a bigger difference than I expected.

    Navigate on Autopilot is Useless (2018.42.3)

    Most of my phantom braking events are due to clear radar false positives, like when the road dips down with an overpass. I suspect disabling radar will improve the situation around here.

    Navigate on Autopilot is Useless (2018.42.3)

    I have absolutely had NoAP properly pass a slower car, more than a few times. It is however maddeningly inconsistent. AP1 was very smooth, but boy howdy when it fails it really fails. I've had it quietly and smoothly send me in to another lane in a construction zone with poor lanes, even in my...

    Navigate on Autopilot is Useless (2018.42.3)

    Having driven both but only owned AP2, I stand by my assessment that AP1 is better within the narrow envelope it's designed for. AP2 has a broader envelope of operation, and is worse within the AP1 envelope. I bet plenty of people would choose the AP1 level of functionality if they could, with...

    News for Model X owners with the dreaded shudder

    Already almost done after 16k? I wonder what is so different, as I got 32k out of my first set. Wear was also very even across the tread despite running in Low most of that time.

    News for Model X owners with the dreaded shudder

    The local service center has gotten pickier about doing NVH-only repairs. I had a candid conversation a while back with one of the techs where they pointed out that they have some people who seem to never be pleased even when they go well above and beyond, and having done customer service before...

    News for Model X owners with the dreaded shudder

    That's super weird. Still having zero issues on my fixed X, running Always Low. I would expect it to come back on Standard rather than Low.

    Navigate on Autopilot is Useless (2018.42.3)

    MobileEye works really well within a narrow operational envelope. Tesla is trying to solve a bigger set of problems. I suspect if they had just gone for AP1 feature parity we would have been effectively done in 2018.

    Navigate on Autopilot is Useless (2018.42.3)

    This all helps to confirm what I already suspected: AP2 quality still depends a fair bit on local map quality and local training. I've never seen a taxi lane before in my life so it wouldn't be a use case here. Instead I get to be ready for a section of highway that just finished construction...

    Supercharger - Woodburn, OR

    Last time I went through Woodburn a few months back I had to to change stalls to get good speeds even though it was empty. The first one I tried actually crackled when I went to remove the plug! This site is high traffic and no doubt sees a lot of wear. Other experiences here have always been good.

    Model X 90kWh battery pack degradation

    I've seen 132kW, which is really impressive when you realize that I had a bad condenser fan at the time, so the cooling system couldn't run at full capacity. I'm curious what the rate will be now that it's fixed.

    Whats the largest Power Inverter you can use in a Tesla?

    The Wagan ones are well built and will feed their rated wattage without issue. As a bonus they also come with decent cables.

    Whats the largest Power Inverter you can use in a Tesla?

    If it's for 'starting up the fridge' surge, I can agree. If it's 'running the worm drive saw' I would still add extra buffer in parallel. It's just a matter of using things right at the edge of the curve.
  36. D

    Whats the largest Power Inverter you can use in a Tesla?

    The inverter will start screaming at you around 10.5-10.8 volts depending on brand. I don't know that I would fly that close to the sun. At that point you're asking the AGM to put out 6C which demands near perfect condition and a full charge to keep the voltage up. A 50Ah or 100Ah AGM to put in...

    Whats the largest Power Inverter you can use in a Tesla?

    Most inverters will shut off at about 11 volts. You want to aim for 2C or less on an AGM meaning doing a 3kW inverter with the stock battery is probably right on the edge with the DC-DC capacity. It would probably work but I would feel far more comfortable with at least another 50Ah in parallel...
  38. D

    Whats the largest Power Inverter you can use in a Tesla?

    OK, that makes some sense. Personally I'd just parallel in a 100Ah AGM alongside the normal battery and let it take the surge loads. $200 instead of $1500, one less conversion along the way. But if you've already got the Jackery and use it elsewhere I see how it can work as a surge tank.
  39. D

    Whats the largest Power Inverter you can use in a Tesla?

    So you're using the HV battery to charge the AGM battery to charge the Jackery to run the emergency equipment? It seems like the Jackery isn't adding much in the middle. Am I missing something obvious here?

    Model X 90kWh battery pack degradation

    Any insight to how the previous owner treated the battery? If they haven't been charging to 90% it could need a bit of time of doing that to calibrate.

    That Motor Trend 1 foot rollout

    Tesla does a bit of that. On their spec the non-Performance units get the full 0-60 and the Performance units get the roll-out subtracted. It's at least disclosed though, and frankly it doesn't matter quite as much as one might think because even the slowest Tesla is a quick car.

    X: What's your 90%?

    It's a solid estimate but some things can throw it off. Not regularly charging to 90% has been known to do it. New would be 295 if memory serves, so that is also within the range of possible, if on the low side.
  44. D

    X: What's your 90%?

    That seems a little low to me. New would have been 275 or so to 90%, yes? However has it regularly been charged to 90%? If it has not, you really need to do that for at least a few charges, as the BMS can get really out of whack if it never gets to balance. Maybe throw a 100% charge with a few...

    X: What's your 90%?

    We're probably not so different in our driving behavior, minus the fact that my trips are only 300-500 miles and more frequent. I'm at 35k or so in 4 years. Often my car sits for three or four days, still at 90%. I'm just not seeing the degradation that people worry about. Since Tesla makes the...

    X: What's your 90%?

    I only charge to 100% the night before planned long drives, because why take that extra wear if I don't need it? However if I suddenly didn't need to take the long drive the next day I wouldn't sweat it. My regular usage pattern is charge nightly to 90%, and my battery is still in great health...
  47. D

    X: What's your 90%?

    There wouldn't even be real damage if you did it a week before departing. If you kept it charged to that every day, that would be significant. Also if you charge to 90% from time to time your BMS will stay in calibration better for a really tiny amount of extra degradation.

    Doing a brake job myself help please

    Tesla cars can only do one-pedal driving if they have a PM motor, such as Model 3 or S/X Raven. Otherwise the induction motor doesn't make enough braking force below about 5mph to come to a complete stop. The logic for non-cruise driving is consistent: it activates the brakes when you step on...

    The older cars don't apply the brakes unless you step on the brake pedal.

    Renton, Seattle, and Bellevue have all done good work for me and generally been responsive.
