    Battery overheated on Model 3 LR 2021? [during supercharging]

    Hello, I'm new to this forum and I have a question for Tesla Model 3 owners. Recentry I wanted to experience a super fast charging session (LG Battery - yes I know) at a V3 SC. So, I made sure I got there with warm battery and low state of charge. I got extremely good speed at the starting of...

    New Model Y. Range questions

    My wife and I just received our model Y that we ordered back in April. The car is awesome to drive I'm hoping someone can help and answer a question. Yesterday we took it on a trip from NC to VA. When we left the car have "312 miles" and when we arrived it has "82" left. The trip was 148 actual...

    Gen2 bouncing between 48a and 24a

    I’ve had my gen 2 wall charger since 2016. Never had an issue charging at 48a. Today it suddenly started dropping to 24a for a while then back up to 48a, then back again indefinitely. The breakers are all double bar and I don’t hear any buzzing or anything that seems out of wack. The gen 2...

    how to test for battery health during a test drive.

    Hello everyone, I've been lurking on this forum for quite a while, as i am interested in buying a used Tesla model S, probably a 2013-2014 85kwh model as a replacement for my 1996 BMW 540I. The cost for newer models is unfortunatly too high to consider, and the model 3 is still relaltively new...

    2020 Model 3 LR never stops charging [resolved]

    Hi all, I had a good search here and across the Internet as a whole, but didn't see anything quite like this. In June, the family ICE car was destroyed in a flood and we decided to replace it with a Model 3. The waiting list at the time was stretching into 4+ months and with only one family...

    Model S Plaid -- Battery Failure -- Day 1

    Picked up my Red Plaid today with 19inch wheels (told first 19" delivery at my Service Center) with 4 miles on it! Delivery experience has gradually gone down hill (my 4th Tesla) and this experience was by far the worst. You purchase a $130K car and expect to see someone other than the 18...

    290mi at max charge after 6 months

    My 2021 MYP just turned 6 months old, I observed the range of charge to the border between “daily” and “trip” decreased over time, from 271 to 259. Today, I played around on the app and moved the bar to max, and it shows 290, vs 303, so I lost 12-13mi in 6 months, expected? Since delivery, i...

    Battery cycle ranges and degredation over the cars lifetime (90-20%?)(95-5%)

    Hey guys, Ive been a huge Tesla fan and investor for about 5 years now. I am finally ready to pull the trigger on my first tesla (long range model S), but I am hesitant because I have a 200m round trip commute every day. I've done the math and figured I could make it there and back even on the...

    Model S Battery Failure - Achilles Heel

    My 2017 Model S 100D with 40,000 miles suddenly started flashing warnings last week and had towed to Tesla Service Center. Diagnosis was battery failure due to water seepage under a fuse cover which Tesla attributes to an impact to this fuse cover which cracked the plastic below. While there...

    Battery Range for Perf Model Y with 19” Wheels

    Hi, I have a 2021 Performance Model Y and replaced factory 21” Wheels with 19” Wheels from T-sportsline. I changed the wheel size settings in the car to 19” Gemini and rebooted. It still shows max range is approx 300 miles at 100% charge on the battery meter. Should that now have updated to...

    Failure of the high voltage junction box - 2014 Model S

    About 5 days ago on a short drive in my 2014 Model S (<80k miles) I started getting the error bms_w008 "Vehicle may not restart - service required." I submitted a service appointment request and the service team actually asked me to come in earlier than my scheduled appointment. They've now...

    Should Maximum Charge Be Changed Over Time

    I have a 2015 Model S. When I first purchased the car, a 100% charge would lead to about 270 miles of charge. Typically, I would charge it to 90% except prior to long trips so it would stop charging at about 240 miles or so (about 90% of 270). It has been 6 years and if I charge it to the...

    Model Y Standard Range EPA Doc & Battery Energy (54.8kWh)

    FWIW, the EPA doc for the 2021 Model Y SR is now available. (Ironically, the vehicle is not?) (Should have put 2021 in the title of this thread though I guess so far there is only one model year of Y SR...maybe mods can add?) It shows 54.8kWh available in their full discharge test. So I'd...

    Impact to the battery by changing rates several times while charging

    I am looking at using the EVSE charger vs Tesla's since it is cheaper and Tesla is not updating its app to allow changing the rate from the phone/wifi to take advantage of solar to charge the car. One advantage of EVSE also is it can be integrated with PiMon which monitors your solar production...

    When I last ran out my battery..

    Pick the largest category that fits your situation. Do not count as a 'shut down', a situation where you arrived at the Supercharger, and it failed to produce electricity -- and you had to go hunting for charge. Also, don't count situations where there was a mechanical/electrical problem in the...

    Battery life changing at home

    Hello, we got our model S recently and just realized we can't put a good breaker is our home for 60A charging or even 30A since we are already at the limit. We have been charging at 15A I wonder if this has any negative effect on battery life, I grew up with the idea that slow charging Li...

    Battery drain while car is sitting idle

    Battery drain while car is sitting idle. Moving to a new city, and have left my Tesla S there for a couple of weeks, before I return. I’ve noticed the battery is draining and a fairly rapid rate, even though it is just parked. I turned off Sentry and climate control. Is there anything else I...

    Bjorn Nyland: New Model 3 Battery Pack Has Temperature Issues in Cold

    Bjorn Nyland just put out a video about some issues with the new Panasonic 82Kwh battery pack in some "2021" Model 3s which I think is pretty interesting. It appears that the Panasonic pack is much more sensitive to cold temperatures than the older LG pack and the car's software doesn't account...

    Battery Charging between LA & SF [edited title]

    I’ve purchased a SR+ model 3 and will be driving back and forth between LA & SF fairly often (~360 miles). Will I be able to make it only stopping and charging once along the way? I don’t mind stopping for a longer 30-40 min charge if I only have to stop 1 time. But since I’ll be making this...

    Have you guys seen a Wh/mi so high?

    Model Y LR with Induction wheels I drive maybe 20 miles a week and pretty much just city driving. My efficiency looks like trash lately. My driving habits have not changed either. The only factor could be that it is getting colder where I live (Seattle) and as we know the efficiency drops in...

    Percent or miles/kilometers - only percent makes sense

    I have driven my Model 3 SR+ for over half a year now and was convinced by one of these discussions that the percent display has no meaning because of the varying battery capacity and that I therefore should use kilometers, which I did. However, what I see now is that kilometers or miles are at...

    BMS Drift - does it really matter?

    So I have seen numerous posts about range decreasing and the wonky BMS, but no one has actually addressed the problem with that. Of course, that's assuming you don't have a faulty battery. I feel like in those cases you'd be able to tell pretty easily. Does having a BMS that's drifted cause...

During those two months of waiting, I had some serious phantom draining while the...

    294 miles on 100% charge - LR AWD

    I've had my Model Y for almost 3 months. I've taken a few trips and charged it to 100% a couple of times. It will only show 294 miles when charged to 100%. Does it sound like there is a problem, or is the display just not super accurate? I was hoping it would show 315 or 316, even though I...

    How much is a new battery?

    Does anybody know? Assume you somehow damage the battery or it goes too low after warranty, how much would it be to have a new one put in? How much the battery and how much the work to change it?
