    Is there any reason why my car's charging at 1 amp less than the capacity of the charger, everywhere?

    Just checked the car, and indeed you're correct -- shows correct in car and incorrectly in app. Super odd. The 2 hardest things in computer science are naming things, cache management, and off by one errors, I guess.

    Is there any reason why my car's charging at 1 amp less than the capacity of the charger, everywhere?

    I've got a march 2016 (nosecone / pre facelift) 90D that's had the MCU2 installed. Whenever I do L2 charging, regardless of where, my car charges at one amp less than the rated capacity of the feed; at home it charges at 240v/15a, at a friend's house with a trickle charger, it charges at...

    Vendor Preventative Maintenance regarding Battery Failures in early Model S vehicles (2012-2014)

    Ex first gen allroad owner. I'm certainly happy they replaced all those parts, and I know what they cost new. Still, pretty time consuming to repair correctly without just downloading a whole new suspension, and I know if I keep the car for as long as I think I'll be keeping it I'll be...

    New 85kWH battery for my 2013 P85+

    I'm of the opinion that a top capped large pack is really valuable even if you never get access to the full range of the pack. You can charge to 100% without hurting the pack much, you can charge to 95% and not hurt the pack at all. You get much better charge rates over the whole available...

    Vendor Preventative Maintenance regarding Battery Failures in early Model S vehicles (2012-2014)

    2016 90D -- still on the older style B2B used car warranty (until june). The car was sagging overnight; they threw parts at it until they'd replaced the compressor, the central valve block, and both rear springs. I wouldn't have put up with such madness if it were on my dime -- each of these...

    Vendor Preventative Maintenance regarding Battery Failures in early Model S vehicles (2012-2014)

    Perhaps they thought carefully about it and did extensive modeling, and after a robust test regime made the change. Perhaps they just got a longer hose, specified it dump "here", closed the ticket and grabbed another beer from the fridge.

    Vendor Preventative Maintenance regarding Battery Failures in early Model S vehicles (2012-2014)

    I took my car to get the AC condensate drain unplugged; they dropped the battery to remedy the problem; as far as I can tell the line still drips water either onto the battery or onto a shield (I can see water dripping down the battery with the AC on). I guess I'll be taking my car apart to...

    Vendor Preventative Maintenance regarding Battery Failures in early Model S vehicles (2012-2014)

    So -- I've changed air shocks in my audi allroad and changed a cam / lifters in my old volvo; but weirdly seem intimidated by this. I guess I'm getting old and lame. Follow to pull out the frunk, then look around for what's obviously the AC condensate drain line, get a hose from the hardware...

    Sorry to be dense; is that the front behind the frunk liner, and you've just run an extension tube some ways away from the top of the battery?

    Vendor Preventative Maintenance regarding Battery Failures in early Model S vehicles (2012-2014)

    With the newer style battery packs (later 85 / 90 and related smaller packs) is dripping water on them constantly as much of an issue as it was with the older style packs?

    Vendor Preventative Maintenance regarding Battery Failures in early Model S vehicles (2012-2014)

    I've got a March 2016 (nosecone) S 90D I recently had my S in for service because the AC box was dripping water into the cabin -- the AC condensate drain had plugged. They had the car for more than a week and explained that they had to drop the battery to clear out the drain pipe, and said...

    2016 model S AC condensate dripping onto floor

    I've got a pre facelift 2016 90D that for a while has been dumping water onto the carpet whenver the AC's on. I bought my car in 2019 where the car had 45k miles on it, from Tesla used, so it's got the 4 year bumper to bumper warranty. The service center said the condensate drain was plugged...

    Yes, another transferable supercharging question

    Oh, I've got no evidence whatsoever. You're welcome to think whatever you want of me, it's a free internet and certainly there's a ton of bullsmoke on it from people knowingly or unknowingly spreading nonsense. I'm just regurgitating what I've read or imagined. The *owner* of a car is welcome...

    Yes, another transferable supercharging question

    Tesla has made deals with several wholesalers such that any tesla processed by those wholesalers will have the lifetime transferable unlimited supercharging stripped from the car. Tesla also, when they own the car themselves, will strip the unlimited supercharging themselves. There's...

    Alternative power when 240 is not available - are Quick 220 good?

    Well, it's 100% reversible... if you find the first outlet in the chain, convert it to the 6-20 (6-15?) outlet and don't hook the rest up, when you go to move out, swap the breaker back to the 120v breaker and put the original 5-15 (5-20?) receptacle back in and the landlord won't know you were...

    Supercharger Shock!

    That rate's set by the site not chargepoint; chargepoint just provides the software, billing and charging infrastructure support. You (maybe?) could put an EVSE in front of your house and make it public and charge at $20 per kwh. Where I work there are chargepoint managed EVSEs that are free...

    Supercharger Shock!

    I suspect most people massively overspend on their home EVSE setups. You should be able to do it for less than $800 even including the Putin tax. I've been fine with a 20a/240v NEMA 6-20 and a cheapo amazon EVSE for the past 2 years, even through cold boston winters and plenty of situations...

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

    So in theory one may be able to speculate that there's no correlation between "battery constrained" and "ethically constrained" ? Corporations in general, according to milton freidman, are supposed to be (law abiding?) profit seeking sociopaths.

    Alternative power when 240 is not available - are Quick 220 good?

    I've got an S that I sometimes park where there's only a 15a / 120v circuit. It charges, eventually. It's also less efficient. I would do as was suggested prior -- have an electrician disconnect all other outlets from a convenient circuit and convert that to 240v; ideally a 20a circuit...

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

    My understanding is there are 2 parts to the battery -- the control electronics and the batteries themselves. The batteries are enormously complex -- they're weird little chemical analog electronic things with 20-30 different dimensions per battery and per battery brick. All of it has to be...

    How are we supposed to get est range @ 90% 100% etc. now?

    In app - click on battery icon twice to get percentage and estimated distance / range. remember both numbers, open calculator right now I have 194 miles of range (Ha!) and am at 72%; 194/0.72 = 269.44444 -- that's my "100%" range. In practice, it may still say "72%" when it is at 195 or even...

    Supercharger Shock!

    It's my understanding that commercial power delivery has a variety of prices depending on time of use and if it is guaranteed, important, or if you sign up for being a the head of the load shedding queue. I can tell a story that a well located and developed site can have very low utility...

    2015 P90d charging questions

    There's a lot of variability in cost and need for a big guns high amperage circuit. In my house, for instance, I'd probably need a new service from the utilities, a new meter, and a new panel if I wanted to add a 40A 240 circuit. Rather than pick that scab, I had a 5-20 outlet with a dedicated...

    Vendor Tesla Model S Battery Extended Service Plans from 057 Technology

    So, if I understand correctly... Presuming I have a 2016 S 90D which was born March 2016.... I can give you $1,799 and you'll mail me a dongle that I put onto my car. I then drive around until March 2024 under the *tesla* warranty. If my battery takes a huge steaming dump January 2026, I'll...

    Alternative power when 240 is not available - are Quick 220 good?

    I spend lots of time at a house that has only 120/15a; it is slow but when I'm at that house I don't do much driving; after a couple days I'm fully charged. i haven't had an issue, though to be fair there are 3 superchargers between there and home, so if I need to turn around and head home...

    LFP Battery Pack for Old Model S Cars

    The car's 0-60 is a function of power output, weight, and traction. The LFPs seem to be able to put out as much power, for a somewhat larger (heavier) battery. They have less power overall, but are able to put out maximum power as well as the existing batteries (just for less time until...

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

    I pulled up the 2020 iteration of the tesla warranty document and it does not distinguish between refurbished and new HV battery; it does have a call out for used roadster parts, so if they would probably distinguish between refurbished and new if they had different coverage.

    Prototype Battery Powers Tesla Model S For 752 Miles On One Charge

    My take on this is: This is exactly what the model S was built for. Prototyping battery technology. Think of the implications of a bolt-like battery fiasco to Tesla in 2017. Catastrophic, but possibly survivable. But imagine the same scenario but with the 3/Y having been built in tremendous...

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

    So all nose-cone cars regardless of build date will have higher sleep draw from MCU2 because there's no standby power from the HV battery? Or is there some other cutoff where some but not all later nose-cone cars have the wire harness?

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

    There are OG roadsters out there with nearly that amount of age. There may even be some roadsters with original packs that old. There are 2 real questions -- how do the packs age and how does tesla (or the broader community) support old packs / old cars? A great answer would be "there's a...

    Well, pay attention to the contract you sign with whoever you're doing business with.

    LFP Battery Pack for Old Model S Cars

    Well, a "90" pack after 8 years is a 70, and filling to 80% and running down to 15% habitually gives you a real size of 55.... While with LFP you can fill to 100% without concern. The MIC 3 apparently has a battery of roughly 55kwh so probably you could stuff 60-70 into an S form-factor, where...

    LFP Battery Pack for Old Model S Cars

    I don't know if tesla's decided what to do with old cars. They certainly seem to support their roadsters better than, say, VW or audi support their older cars. Why would tesla switch to LFP for replacement S battery packs? They're battery constrained. A cell that's going into a pack either...

    Model S winter range

    Looking at that, the big difficulty is the distance from the watertown supercharger; its a 120 mile round trip. I've got a 90; if I were to do this I'd make sure to fill to 95% or more at the watertown charger and not rely on the L2 chargers in Canton. I'd try to top off at one; the one in the...

    I may be in the minority, but I am really hoping that tesla will offer a pack with LFP cells as a replacement pack for legacy models coming off warranty. Hear me out.... My car, new, had maybe a range of 288 miles, now it's got a range of 272, and by the time the warranty's done probably 260...

    First gen air suspension sagging overnight

    Used 2016 90D, what to look for?

    Sorry -- the TL;dr for "what's wrong with the V1" is this: It will continue to degrade probably for the life of the battery. Most other tesla batteries degrade a bit in the first 2 years and then stop degrading.
  46. C

    Used 2016 90D, what to look for?

    72% is high enough to get a roughly correct view of your battery's capacity. I've never been able to 100% verify the early 90D range; I believe it is 288 and the "294" range is from the later refresh. I'll stand by my opinion that absolute range isn't really an important feature -- assume...
  47. C

    Used 2016 90D, what to look for?

    There are scan tools that will tell you precisely the capacity. If the car's charged to 80-90% you can extrapolate the approximate capacity. The lower the state of charge the less reliable the extrapolation becomes. I don't think the 90 chemistry was ever affected by chargegate, and I don't...

    Used 2016 90D, what to look for?

    I've got a pre-facelift 2016 90D with 66k miles. It's been a good car; I got it in 2019 (with 45k miles) and when I got it the 90% was 251 miles (100% 281 miles). It's got the "bad" V1 battery. It now has 273 miles at 100% or 246 at 90%. Just recently it charged at 111kW with the battery at...
