We have 10 year data on old “S” models & Tesla published it. It was 12% degraded after 300,000 miles in 10 years. This is great outcome. The LFP battery of the recent model 3 & Y should be even better !

I have a 2022 M3LR (NMC/A Batt) and a 2022 M3RWD (LFP Batt), both made in China. The LR has covered 38,000 Km with exactly 5% degradation. The RWD has covered 75,000 Km with 4.2% degradation. (data out of Tessie App) The LR 99% 7Kw charging (32amp single phase) to 80% capacity and the RWD 70% supercharging to 100% capacity. The LFP battery durability so far has really impressed me with a similar driving range to the NMC/A battery @ 80% capacity. Whadyaknow Elon was right! If it wasn't for the ocassional road trip I would take the LFP M3 on a cost / hassle per km basis everytime.

I have a late 2021 LFP Model 3 that came with 252 miles of range brand new. After 50,000 miles driven it now estimates 238 miles at 100%, for a rough degradation loss of around 5% (assuming the range estimate is accurate). Not too shabby. I always Level 2 charge around 15 Amps and normally go down to low percentages between charges, while also hitting 100% once per week as recommended by Tesla, and Supercharge a few times a year for road trips. However I've recently learned that it is better for the life of the batteries to not always be "deep charged" from 0-100%, but rather short slow charges to minimize degradation. So now I just plug in every day and let the car slowly crawl up back to just enough to make it above where I left off percent-wise yesterday (until the end of the week when I charge to 100% again).

This is an underrated point. Almost every EV owner I know seems to think discharging the battery to almost empty is ok. I think it’s a carry over habit from the way people refuel their gas cars. The manual also states to “leave the car plugged in when not in use” in capital letters too. IE: charge it as often as you can.

I sold my 2018 Model 3 Long Range, which my wife had reserved in June of last year, to purchase a Rivian. At the time of sale, it had around 61,000 miles on it. I remember that when I first received the car, it showed a range of almost 320 to 325 miles on a full charge. However, when I sold it, it was showing around 280 miles of range at 100% charge. I didn't use the supercharger much after buying the car, maybe about three times, and I typically charged it to 70% daily, with occasional 100% charges for long-distance trips, about two or three times a month. I've heard people say that the battery now is different from the one I had back then, but I'm not sure about the differences. Nonetheless, I don't think the decrease in range that I experienced is too bad, considering my usage

Thank you for the video. Very clear and easy to understand. LFP charge to 100%! For drivers with home equipped charging solution, I guess it means that whenever you are home, regardless of you battery level, just plug it in and leave it there, is this correct? What about for users whose charging facilities are shared, like myself? I have available normal charging and supercharging, but its not possible to just leave it connected all the time when not in use. We charge to the desired level and then move out from the charging spot and park the car. So, my question here is at which point should I charge? Wait for around 20% and charge? Closer to 0? Or for LFP battery type does not really matter, if I charge to full from 0 or from 95? How about supercharging VS normal charging? Thank you edited typo

Typically you don’t charge on the road for more than 10-15 minutes at a time. That’s when you get the fastest charge and the longest range for the least amount of time. A trick you learn watching cross country EV racers. On U tube. Nobody puts a full charge because the last 20-30% takes the longest amount of time.

I have slightly different experience with my 2021 LFP M3. I have charged my car once per week to 100% at home with 11kWh Tesla charger. The degradation after 55000 km is around 5% from 420 km to 401 km of nominal range. But it is also important to check capacity at the start and still available after that 55000 km. It that case, based on the readings from the application I have, degradation is 7.2% (a drop from 55 kWh to 51 kWh still available in the battery pack). Interesting, right? Once per year I do 2500 km trip. I have noticed those supercharger sessions brought the biggest impact on the nominal range drop. The drop stabilized over the last couple of months so that degradation trend discussed also in your video seems to be confirmed: the biggest drop will happen up to 50000 km and then will be slow. However, I am afraid that additional supercharging sessions on the long trips will cause additional degradation of my LFP battery. I keep you posted. If this is indeed confirmed then the charging power also needs to be taken into account when evaluating degradation characteristic of LFP battery.

LFP is used for solar instalations, where are charged to 100% almost everyday, LFP bateries should last over 6000 cycles when used between 100% - 10%. Also this batteries need time to balance the cells, if you never give time the battery at 100% it wont balance and loose some capacity. The good thing is that this is fixed by leaving some hours charging after hitting 100%

@justinsugay1149 2 ай бұрын

I'm wondering how much of the initial "degradation" is due to calibration of estimating range to one's real world experience? Meaning it's calculating what you specifically will get with the routes, charging habits etc you literally put this specific car through vs it actually having any real loss over the first few thousand miles. I think from ~5k to 50k miles will be a better reflection of any actual degradation imho. So say you get 268 consistently from 2k on... then the car gets say 261 at the 50k mark, that would be the accurate degradation for your vehicle at 2.6%. It would be considered 4.3% from 0 miles but I think one needs to give the car actual miles to give the BMS the data to calculate range more accurately and no one is going to have consistently ideal enough conditions to get the max say 273 miles. I don't have data to confirm or negate this but it's something to consider.

What's the best procedure for measuring what mileage is available at 100%? Is it simply charging the battery to 100% and looking at the display for the mileage? Is the Tesla calculation to be trusted? I have a dual motor with NMC battery. I prefer to avoid charging to 100%. But to get an idea of degradation do I need to do the charge to 100% to check it? That kind of encourages some potential degradation just to check degradation. Seems counterintuitive. I understand in the service section of the software there is a section relating to battery health. I've not explored that but can anyone explain how that battery health info is obtained?

Supercharging to 100% takes ages and might cost you the extra fee if the SuC is congested. If you don‘t run the SR to too low SoC, you might get away with full charging once a month. If you want the benefits of the high charging speeds at low SoC, take the LR.

The NCA failed at 24K but all is good with the warranty covering it; plus they installed a new stronger suspension to compensate for the LFP being a bit heavier apparently. Anyhow, I am about a week in with this and found that at 99% it says "calibrating" and I waited for over 10 minutes and I stopped as it seemed to stay like that indefinitely. Is that bad? Should I wait? I had to go somewhere at that point but do I need top off to 100% or until it stops on it's own? What are the possible repercussions? When I stopped the charging myself instead of waiting it then showed 100% with 263 miles of range. Everything seems good but I want to get the right habits early on. Thanks!

Great video as always- Thanks. My experience with 2023 M3 SR China built, 18'' tires. After 14 month - 25000KM (15.5K miles). According to car: drop from 439 to 425 KM - 3.5% degradation. Usually 1% drop every month. Using 11KWh home charger, charging to 100% once or twice a week - not at night. Charging to 100% is done typically when I am around 30-40% Soc. The charger- and car -are in an underground parking, so not exposed to the elements. I'm almost not using Superchargers (4% of total charges, maybe 10 times total), and never above 90%. I don't know if the driving distances and seed are effecting battery degradation, just for general knowledge: Daily drive is between 12-14% -depends on the weather, with some days extended to ~18%. Every 2 weeks, I'm going 300 KM(~186 miles) longer drive highway speed. 4 times a year I'm doing a longer trip (800KM=~500miles) - also highway speed. in these trips I usually do supercharge.

@tonymai1844 5 ай бұрын

slow charge is better than DC fast charge. the heat of DC fast charge kills the battery. So with the LFP HV batt pack, you can use 110v ac or 220v ac to charge what ever level you want, two or once a week up to 100% I believe it is ok. If I can access to L2 charger at home I charge it any time it get down to 40% up to 90% and the next time is 40% to 100%. Or you can do two or three time up to 90% then one time 100% full. So you can get the range estimate more accuracy. that is all about those lithium battery. I dont worry about how many miles any more because you have to use the energy to get comfort, to drive, to use ac or heater and EV wont be exception. You pay to play.

Mark, mine is a early 2022 60kWh (now exactly 2 years old) and its gone from 100% charge indicated range has gone form 438km to 416km which is 5.0% degradation (if range can be trusted as a measurement for degradation). Have only done about 24,000km so far and about 90% of my charging is AC. For the first 1.5 years I usually only charged 100% once / week - at that stage range was around 419km, but more recently have charged multiple times / week and range has not dropped any faster (in fact maybe less) but then I have seen posts that show degradation slows down so that may explain it. I see quite a few Model 3 LFP in NZ (Trademe etc) that may be doing better than mine, but not sure if thats significant at this stage or if I should change my charging habits. At some point I will discharge to a low level and recharge and see how many kWh its takes.

@lassewestvanghougaard4856 6 ай бұрын

It is worth noting that the range estimate fluctuate a lot of the LFP. One week it said 257 Miles of range on my M3 RWD, I was in slight shock but crossed fingers that it was a unbalanced battery issue with the LFP. This week it shows 265 Miles. So depending on the battery balancing, it will show different range estimates. Since I rarely ever charge the car to 100%, it is possible that the BMS doesn't know the state of each individual battery unless it is charged to 100% once in a while. Also want to note that the car is now completely drained at 0%, I had to get the car tow to nearest supercharger 2.5 miles away. In a couple other instances I had 5 Miles left after hitting 0%, but not anymore. I'm certain that this is due to new software updates. In other words: 0% means 0%.

@rudycastillo4150 6 ай бұрын

Supposably reaching 0% you have about 10 mile worth of battery

@lassewestvanghougaard4856 6 ай бұрын

⁠I believe in recent updates, 0% now means 0% battery left. I had to pull over within 5seconds of hitting 0% Note that you have to jump the 12v battery for 20seconds to turn on computer to accept supercharge. But no stress non-the less. It is better to get a tow on a car with 1% battery since you will be able to put car in neutral and roll the rear tires without having to use dollies on the rear tires. Flatbed is a bit faster way to get car towed.

@Dubitz 6 ай бұрын

That is exactly why they recommend you charge to 100% once per week to make sure the BMS is correctly calibrated. It can "forget" how much capacity it has and is only accurate between 95% and 5% I've heard due to how the voltage of the LFP pack works.

@justinsugay1149 2 ай бұрын

@@Dubitz That's a good point to remember and apply. I don't like getting to far below 10% and every estimate that leaves me with 5% or less on a trip is "gulp" not confidence inspiring. I had to get down to 1% once and was sweating. I'm also afraid of the "damage" that may do but I understand in theory it can be actually good but how one goes about that in a good way I'm not sure. We all have different needs and I understand why one may end up letting it get to zero or close to that often. Hopefully it all keeps working. Best

Another thought provoking video, and comments from other viewers. I have a 2021 M3 SR plus MIC with LFP. Range at new was 422km and now after 33,500km shows 401km at 100%. Thats 5% loss. Most charging is done at home via 7kW outlet using Tesla mobile connector to 100%. Tesla app charge stats show 11% supercharging and 28% other. I don’t drive regular trips so milage varies, eg some weeks I may do just a few km and others 100s. My question is about whether I should charge weekly regardless of SOC as opposed to waiting until SOC is below 50%? Also i have a small capacity rooftop solar system so it cannot supply enough to charge fully in one session. For best battery care should I just charge to 100% and consider the solar contribution a small discount or just top up to 100% over a number of days to optimise the sloar power?

If you have an LFP battery and your daily commute is 100 miles so you have to plug it in every night, would you leave it set to 100% every day? Or 85% daily and then 100% once a week? For the long-term health of the battery? Asking for a friend...

My M3 SR+ MIC w/55 kWh LFP is from dec. 2020. After 50,000 km (31,000 miles) in 3 years, the EPA range has dropped from 410 km to 381 km, corresponding to a 7% degradation. This value is unfortunately higher than those compared to in TeslaFi. I have no explanation for this. I charge about 2 times a week at home on 11kW AC and always to 100%. DC charging is rare. One year ago, the EPA range was 388 km, according to TeslaFi.

@rhiantaylor3446 6 ай бұрын

Of course we shouldn't lose sight of the other motivation for manufacturers recommending a 100% charge for LFP cells - this is the only sure fire way of determining available range as battery voltage is a less effective indicator of charge status due to the flat discharge "curve". Also worth picking up on the observation that 100% means different things depending on the settings used by the manufacturer - it is not always 4.2v/cell for NMC etc cells and the more conservative the "100%" charge level, the less of an issue it will be.

@arubaga 6 ай бұрын

It is important to realize charging a LFP battery to 100% is for the purpose of range calibration. I do it 2 times per month at 17 amp setting, then drive as soon as possible to drain the battery from 100% to 90%. For the rest of the time I keep the battery at 60% charged. So far I have very little range degradation. Another tip is never DC fast charge the battery above 80% charged.

@ptviwatcher 6 ай бұрын

@thelimitingfactor gave awesome insight on this issue! I have the new M3 Long range and I usually charge to 65% and my daily use drains it to around 40%. My knowledge on degradation was only on dendrites due to fast charging in cold conditions and material fatigue (anode/cathode) due to volumetric changes during cycles (that's why I charge every day & only subject the battery to a max of 25% charge cycle) . But if electrolite degradation is worse of an issue than material fatigue than perhaps I should be cycling between 25-50% instead of 40-65% to keep it at a lower voltage. How can I confirm this?

LFP is so different, if you look at the voltage gadient, you see why. From 2% to 98% it is nearly flat. Driving your car down to 90% after a full charge is pointless. Down to 97% is low enough, most likely even 99%. The voltage drops fast from max. 3.6v full to ~3.3v where LFP likes to be. You also don‘t need to keep it between 40-60%, that is better for NCA/MNC but not for LFP. Between 10-99%, it is just fine. You can not tell if the LFP battery is at 30 or 90% by voltage or any other way, just impossible. That is why you need to charge to 100%, the voltage spikes right at the end. That way the bms resets to 100% and then roughly counts the kWh in/out of the pack for SoC.

In winter in the mountains of Colorado, I tend to have the car at 80%+ charger in the morning, out of a desire to have loads of charge if ever stuck somewhere for a while (like the bridge failure that closed an interstate for hours...the closest way around an obstacle can be hours extra of driving). But I want to learn more about optional charge levels for battery life, for my LFP batteries, to see how long I can maintain high capacity. So far no signs of degradation after 7200 miles.

@jeremyrom Ай бұрын

I want to point out that i dont think anecdotal loss of range comments are useful due to BMS wander (especially for LFP). The most accurate way to see your degradation without additional tools/apps is to discharge to 0-5% then immediately charge (ideally the fastest level 2 speed you can get) to 100%, then allow the car to sit at 100% for a couple hours. I doubt people are doing this when quoting their degradation numbers. The internal tool in service mode essentially does this, but i doubt people use the degradation test within service mode either...

I think the last part is wrong 3.1v at 10% soc is pretty normal. The voltage drop is really steep at the end of the ocv curve. So I would guess it could and still end up at 2.5v at 0% soc. This can also be seen on spec sheets for lfp cells. 3.65v is solid max recommend voltage of the cell manufacturer for 100% soc. So I don't think Tesla really goes easy on the cells. Normally it's the opposite. Tesla is not known for keeping a lot of buffer.

Most people do not realise that to protect the battery the algorithm only normally lets the battery work between 20% and 80% when car is new, but as the miles and battery degradation builds up it incrementally allows the charging to encroach on the 'damage areas' of 80%, so battery degradation is non-linear because the further it goes below 20% and above 80% the faster the battery degrades. Most EV have 'limp mode' where although remaining range is zero, you can access that last 20 % ( and risk battery damage ) by 'overiding' the system.

I am still relatively a new TM3SR owner (10 months) and I am still confused when it comes to charging this LFP battery. I have gone from 272 to 261 miles of max range. But, I have also tried different charging habits to maximize efficiency. At first, I was charging at home (level 2) to 80-85% daily and then 100% on the weekends. This charging habit was getting me a max range of 271. Then somewhere during winter, my max range dipped to 269/268. Then I started to charge daily to 100% and my max range dropped to 267/266. Recently I reverted back to 80% daily and 100% weekends. Then today after coming from the SC (which I normally do not do) and plugging into my Level 2 home charger and setting the charge limit to 100% my max range now is 261. That is an 11-mile / 4% decrease in range in a very short 10 months of driving with 12,000. So please define regularly charging to 100%. What does that mean? If you plug in your vehicle nightly then aren't you regularly charging to 100% on a daily basis?

Sorry but Tesla statements are a bit confusing: if I should leave 100% charge limiti EVEN for daily use and charge to 100% at least once a week...does it mean that I have to limit daily charging not by pad limiter, but instead by wall cahrger? in order to stop charging before it reaches 80%, for example, having left charge limiter to 100% for BMS reasons? LFP battery of course

As I understand it what you should do with a LFP Tesla is set the charge limit to something less than 100% so for example set it to 80% in the app or the c ar. Then once a week or so set it to 100% and charge it to full. Setting there charge limit to 80% for example simply is like turning the charging off at the wall yourself only the car does it for you. This does not matter with the BMS as in order for the car to gain an accurate range estimate it needs to be charged to 100% for the BMS to calculate the figures properly. This means that the car needs charging to full. So even if you set the limit to 100% but turned off the charger at 80% the BMS would not have enough data to calculate true range. You can of course leave the charge limit to 100% and charge to 100% everyday but that might lead to a bit more degradation though I am not sure how much. Hope this helps.

After 3 years and 20k miles with my 2021 Model 3 with nickel based batteries, I've lost 1.49% range. 344.62/349.82

🔴 For NCM battery I found that if you keep it between 40-80% and charge every day or every other day, this strategy is the best thing you can do to preserve max battery life.

I drive my MY every day and charge to 100 percent and with 400KM I have experienced a loss in range of .14%. Tesla is the 18th best car I have owned

Also: Tesla already limits the LFP to 90%, its float voltage is 3,54v per cell while 100% float voltage for LFP chemistry is 3,65v.

Got my Model3 RWD LFP last January 2023, it's about a year and 7000 miles. Now charge to 100% with a range of 263 miles down from 272 when new 3.3% degradation. it started to level up or 263 miles two months ago. I only charge L2 charger at 32A and twice a week. Update: 4/12/2024 at 9,500 miles and one year my range now is 258 at 100%, 5% degradation so far. will it keep coming down? Tesla 272 EPA is way off.

slow charge on L2 wont hurt the battery very much. those mileage estimate is not telling you any degradation. you have to go to service menu to do battery capacity test to find out how much KW the battery takes and how much KW that battery out put. That said method no one can do because nobody can test the HV battery in the vehicle, except tesla software in service mode. But I dont trust that function either. tesla hv battery has to be either working normally or died then you can get warranty for the replacement. I dont even care about capacity reduction any more. Just do slow charge on the L2 and you will be fine with the LFP.

Do you charge twice a week to 100% or just once?

@jimmykan7873 5 ай бұрын

Yes, I charge 2 to 3 times per week to 100% all the time.

I dont think Daves comment is accurate. Did he measure during the charge cycle, or after it completed i wonder? You cant balance the cells without going into the knee of the voltage curve. (ie 3.45v-3.65v range). Trying to balance at anything less is almost impossible and pointless for keeping the cells in balance with each other.
