    Sudden capacity loss

    Up until a couple of weeks ago, my 2021 model S LR (34k miles) would charge to ~385 miles if I needed a full charge. I noticed my normal, 80% charging was not starting at what it used to. I am suddenly only getting about 350-360 miles out of a full charge or 280 miles out of an 80% charge. I...

    Significant overnight drop in battery capacity after lightning strike..

    I have a 2023 M3 Performance with 5,700 miles on it. I've been using the Tessie app since about 2.5k miles to track battery health. I have been tracking on a consistent line just under "fleet average". The other night we had a lightning strike in the backyard, which resulted in several GFI...

    2013 P85 Needs HV Battery Replacement - Options?

    My beloved OG (vin P13161) P85 appears to have driven her last mile. A few days ago, got an error code that max charge capacity was reduced; appeared to be some kind of short as error codes were cycling and battery icon was changing. Called tow truck, he "jumped" my 12V and I was able to get...

    MYLR2021/ 27kMiles/ Battery Degrading already?

    I charged my MYLR 2021 100% last night so I could take it from Raleigh to Charlotte NC. A distance of about 180 miles. By the time I got close to Charlotte- about 50 miles short, the battery was at 35%. A whopping 65% eaten in just 135 miles!! Doesn’t digest. Have you guys seen this happen in...

    Measure the current capacity of the hv battery

    Hi, is there a any accurate way to measure the current capacity of a Tesla model 3. I read about charging to 100%, discharging it and do the math, but is there not a more accurate way to do this? If its not possibly on my own, is it possible to do a measurement in a workshop?

    Range on road trip much lower than expected (<200 miles on full charge)

    My car is a 2121 Model Y, with 20" Induction tires, just upgraded to the Holiday release. Taking a road trip from Seattle to Eugene OR. Taking the trip on I-5, I've noticed that depending on my speed, I'm getting as little as half of the nominal range. Once I got to measuring, I noted the...

    Long Distance Driving Range

    Hi everyone, I just had a general question. I recently ordered my Tesla Model 3 Standard Range Plus here in Montreal Quebec (taking advantages of those sweet government incentives). Expected delivery in Jan/Feb 2022. I work as a Field Service Engineer and this would become my daily driver. The...

    14 Grand and no more range wtf

    Hello everyone . Just dropped 14 thousand on a “remanufactured “ 85 pack for the car 2012 s. New pack is still 216 miles range when 100% full. I’m close to raging angry. Should I be happy paying 14 grand and getting a used pack with no more range at all ?

    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...

    Battery Range decreasing

    Since i got my Model Y in June 20, the range is constantly decreasing every month. It started at 316. Now it is at 301. Any one else experience the same? Should i be worried?

    Energy used since last charge does not match true range

    We took a nice fall drive with my M3 SR+ that I bought last year. I started with 100% charge, with a range of 227 (max when new was 231, not 240mi.) It was cool out so I set the interior manual temperature to 65 deg with A/C off. I have Sentry mode on when away from home and parked for about 5...

    Request for info on SR (NOT SR+) 2020 Range & Constant Info (and a 2019 datapoint for reference)

    Up until today I didn't realize there were any SR vehicles sold in 2020 model year (or in 2020 in general). But, it seems that there have been. I am not talking about the SR+ - obviously those have been sold this year. For range/constant documentation, for anyone who has an SR (not SR+)...

    Long term storage

    Hi Forum - I am leaving town for 3 months and do not have a garage to store and plug in my Tesla 3 so looking for another solution. I live in Potomac, MD. Can it go that long unplugged? Is there a storage lot I can pay to use? Is there a trusted, bonded service provider that can come and get it...

    Advertised EV's should more realistic after the first charge @ POS

    So when you go to purchase your SR+ with a stated range of 240 miles do you realise that after the first full charge it will never reach that range again. First year 230. Second year 212. Before a level off this is the nature of lithium ion technology. But does the consumer new to the game...

    Range degradation for 2020.28.6

    First time in ages since I have done a 90% charge then switched to miles for a peek. Out of the original 240 my SR+ is rated for at 90% I have 209 miles of WLTP range @ 21c ambient temp. This would seem to represent just under a 3% range loss for 5690 miles at 9 months old. My thoughts on this...

    Acceptable Degradation?

    2017 Model S 75D (259 mile range) Has not been charging to capacity for a couple of years, expected. However mine has 33,532 miles and is showing a battery degradation of 10%. Avg 347 times 163 mile projected range, divided by 84% = 0.897793650793651 First is this correct n the calculation...

    Should Tesla do something about my degradation?

    I own a 2013 Models S 60 (EPA rated range 208) purchased in September of 2018. After taking delivery I charged to 100% and the rated range was 177 miles. I brought this to Tesla's attention immediately and the response was "it's normal". Now, a year and a half later it gets 160 rated miles to a...

    Battery Capacity Calculation

    Searched forum for this. Found some threads, but they seemed to over complicate what is a simple calculation (unless I'm missing something). So I decided to post my own. To calculate your total battery capacity you will need to drive your Tesla for at least 15 miles, preferably 30. At the...

    Model S as a Long Range Commuter Car

    I am considering taking the plunge into EV's with a Model S, the technology and performance are the draw for me. It is also intriguing that there is not much to wear out vs. a conventional engine. This could be a car I could keep for a very long time. But there is a catch: My drive to work is...

    Confused about Plaid/Refreshed Model S

    So, I'm currently in the market to buy a new Model S. I love everything about it. While I want the car yesterday, I want to minimize buyers remorse when the next refresh hits. I had settled that I'd wait until the Plaid Model drops (summer 2020?). However, range and comfort matter far more to...

    Do miles even matter anymore?

    So shortly after buying my model 3 the first couple of runs were done with miles. I just wanted to see what I could really get before the real cold set in. So 220 ish was not bad I was not driving eco and ac always on. Then I decided to switch to percentage and plan my routes that way. I found...

    I am about to buy a used 2014 model s 60 with 80k miles for 28k. Am I making a huge mistake?

    I have all the service records and alot of things were replaced in the vehicle including MCU, 12V battery and drivetrain. However the HV batteries have not been replaced. The batteries do have 2 more years of warranty on it but nothing else on the car has a warranty and I spoke with tesla and...

    Range Loss Over Time, What Can Be Expected, Efficiency, How to Maintain Battery Health

    i bought my model 3 in aug 2018. After the software upgrade I only got 316 miles when charged to 100%. Last night I got only 312 miles from 5% SOC to 100%. A 4% degradation within 10 months? Have others degraded similarly?

    URGENT advice needed on range issues with new Model X.

    Hello. I purchased a model x long range and I am getting much lesser km to actually drive than the rated range. Sometimes less than half. When I spoke to Tesla, they were surprised by this deviation from range estimates but have not offered any concrete reason. My usage is around 285 Wh/km...

    Tesla appointment for battery health concerns mysteriously disappeared

    I have had my M3 SR+ for over 4 months now and drove for about 7k miles. The specified range for this car is 240 miles. My regular charging limit is set to 80%. The Miles range on top left of the Dashboard is now consistently 182-183 miles when charging completes. I believed that range number...

    Help Me with Tesla Math

    I've checked this several times and I'm not getting it. Trip of 124.8 miles, 300 Wh/mi average. 100 kWh battery started at 76%, ended at 33%, so 43 kWh used if no degradation. 124.8 miles * 0.300 kWh/mi = 37.44 kWh + 33 kWh remaining = 70.44 kWh starting. Wait... that's 5.56 kWh short...

    Battery Capacity Down to 86.8% After 18,000 Miles

    Many here suggest the battery should be occasionally cycled between 100% charge and near 0% charge to keep the charge measurement calibrated. So I did that a couple of times. The first time the battery took a very long time to finish after it had reached 100%. It indicated around 8 kW...

    Model 3 maximum battery size is 75kwh

    Elon replied saying this : @kryniog The shorter wheelbase only allows for a 75 kWh pack in Model 3 at current cell/module energy densities..... So with this we can assume the largest battery size for the model 3 will be 75 kWh , makes sense why they removed the 60kwh model s , and made the entry...

    Charging habits?

    I know there's been several posts on the virtues of not charging to 100%, on not worrying too much about this etc. But I thought it would be interesting to find out your general charging habit as it relates to charging your Tesla to a 100%. Feel free to add any comments/insights. Thanks!

    So has anyone already received a new S 60 with software-limited 75 kWh battery?

    Is it still speculation, that the battery of the new S 60 can be charged till full (=80% of real capacity) at all times without downside? the software-limitation is implemented in a way, that the charge slider does not allow to be moved beyond 80% (capping capacity only from the top end)...

    New 70, comes with a 75 (disabled) would 100% charge ~ 93% charge

    We all know to help retain the life of the battery we must sacrifice range on daily charge to 90%. If the new Model S 70 is "really" a 75, would charing the battery to 100% really equal 93%? My question isn't if I should change to 100% regardless, just curious about how the artificial lowering...

    To Increase Range, Could Tesla Just Stack Battery Packs?

    Recently visited a Tesla store and saw the "simple" design of how the battery pack is the floor. With a flat design, couldn't Tesla just stack the battery packs to increase range and battery capacity? It seems like it would make sense, especially since everything above the undercarriage is just...
