Please note that NOT charging to 100% can prevent the BMS from properly balancing the cells, in addition to losing track of the state of charge (SOC). If the BMS cannot properly balance the cells, you will actually put MORE wear on a subset of cells rather than less because a subset of cells will hit the cell voltage cap regularly. When you charge to 100% and the BMS is able to keep the cells in balance, then NO cells will hit the cell voltage cap. So you want to charge to 100% at least every once in a while. If you are truly worried about voltage stress, all you need to do is drive a little (like 1% of the battery capacity's worth) after fully charging, before parking the vehicle. -- At a cell level what is happening is that normal charging will take an individual cell to roughly 3.55V/cell. The BMS cell limit is typically 3.65V/cell (so normal charging, if the cells are balanced, does not reach the cell limit). The absolute limit for LFP is typically around 4.2V and electrolyte breakdown starts at 4.6V. When cells are out of balance, some cells will be low and some cells will be high, meaning that at full charge for the pack, some cells will actually get far closer to the 3.65V BMS limit, putting more stress on them. With LFP, unlike NMC or NCA, the voltage actually relaxes after charging is complete while still maintaining a 99%+ state of charge. The "float" level for LFP is 3.35V to 3.375V/cell... you can see immediately that the float is substantially lower than the charging target. This is why driving a little after fully charging a LFP pack is a good idea. It will at least get the cells down to the float voltage, vastly reducing voltage stress on the LFP cells even though the state of charge is still 99%+. So... keep charging to 100% every once in a while. (This information applies to LFP only. NMC chemistries behave differently). -Matt

I've heard that after charging to 100% you also need to discharge to a low level without in-between recharging to fully balance the cells. Is it true? For NMC, charging at 25% SOH to 75% seems optimal for minimal degradation and practical everyday usage (or 30% to 70%, but there is no real gain in narrowing that window further).

I'm using the Tessie app (which is excellent) and that shows that my 2022 Model Y RWD LFP with 15,500 miles is at 2.5% degradation. It plots a dot of this on a graph every time you add more than 5 kWh and I can clearly see mine leveling out after the initial dip that we all know happens early on. I mostly charge at home at 7kW usually once its down to around 60% and always back up to 100%, but I've also used superchargers and I've had the battery right down to 3% a couple of times, so its fairly varied use. Lots of miles at 65 on motorways too. I genuinely think you don't have to worry about it. Just plug it in when you need to, take it to 100% once a week as advised, and just enjoy the car and try to forget about it :)

The main reason for the recommendation to charge to 100% at least once a week is about battery calibration, so the car’s system knows where the full capacity is, otherwise it cannot calculate range and capacity accurately when you are out and about and heading to your next charge point. Apparently this is a quirk of LFP batteries, unlike the NMC batteries.

LFP batteries have a flat voltage / charge curve so voltage is a minimal use in determining battery capacity. The best method of determining capacity is via a calibration from below 10% up to 100% (in other words, from the lowest voltage to the highest extreme). The battery management system then knows how to capacity limits of the battery and can track energy into and out of the battery and can accurately predict range and battery capacity.

The thing about battery degradation that is never mentioned is that the performance of the car doesn't change at all. It will still accelerate exactly as it has always done and the full power remains. The only thing that changes is the total available range. And as nobody ever runs their EV down to zero, and usually not below 20%, then losing a few miles makes no difference to their journeys. They will always fill up well before it becomes a problem. And there are many early warning dash notices to react to. Much like petrol car drivers do, as it happens.

On those odd occasions we use fast charging we nearly always stop the charge at 85%, as soon as roll back commences.

Hey folks, I have 2024 model Y RWD LFP that covered 8000 miles to date. I charge to 100 percent twice a week and run down low, between 20 -5 percent every time. Seen a fair amount of towing and fast charging too. No battery degradation to report. My Vauxhall Corsa-e on the other hands is down 5 percent degradation after 28000 miles. Seems to have settled there for nearly a year. I do think the LFP benefits from full cycles. Chargers to 100 percent and run it low.

Started out reporting 442km (274.6km) and now reports 415km (257 miles) after 2.25 yrs and 39,000km (24kmiles), so a 6% degradation (if it is not adjusting for my driving habits). I have been charging to 100% regularly as recommended . I am now getting a 1km drop every 1500-2000km or so. I did notice that when i went on a road trip it lasted a lot longer (>3000km) before a range drop. I have noticed that a range decline often occurs after i charge to near 100% (when i have to stop the charging early) and then the next time i charge to 100%.

Are you confusing degradation and driving efficiency? To gauge the degradation you need to see what voltage each cell holds. If you don’t drive as economically as Tesla estimates most people will the car will alter the range shown accordingly, nothing to do with the state of degradation. (You could very well have battery degradation, it’s just the method you are using won’t tell you).

No, LFP doesn't work this way. With LFP, aging does not effect cell voltages at all, it just effects how many amp-hours you can stuff into them. A LFP pack, no matter how old, will run the same voltage ranges as it did when it was brand new. -Matt

I have a Tesla Y LFP, RWD 2022/november, 15,500 miles. Battery degradation is 2.39%. I almost always charge up to 100%, I start charging when I have 30-60% of battery which is 2-3 times a wek. if I just fill up a few times and it's not 100% charged, the next 100% charge it shows me 1-4 miles less range, but if then 2-3x in a short period of time I charge up to 100% it goes back to the previous range. In my opinion, these are not real losses, but losses in the inaccuracy of readings due to low battery voltages.

According to the value read through my MG4’s OBD2 port, my CATL LFP battery is just under 3% degradation. MG programmed the BMS to add a daily 0.01% degradation in the first year since the battery pack was manufactured, to account for the LFP’s calendar aging. LFP degradation is then computed when doing a 5% to 100% charge. So the number fluctuates over time but the speed at which the battery degrades is less and less over time. MG only guarantees 70% capacity after 7years.

Battery degradation is not linear, that's true. There's a sharp drop off to start with, which levels out over time, and (as far as anyone knows, because EVs just haven't been around long enough) there's no sudden drop off point. Batteries just degrade slowly and steadily, and unless you have a Nissan Leaf, with horrendous battery management, that decline should be quite gradual. Every pack is different. Some are going to be better than others. It really is the luck of the draw. LFP does like being all the way to 100%, that's for sure. There's zero reason not to do that. Right now it's still early days. When you get around 50,000 miles, you should be able to see the straightening of the line, and project that trend out into the future. If you know what range is sufficient for you, this should give you a point in time when your vehicle is no longer practical. I suspect that date is a long way off, but i'd be glad to be put right.

Someone on FB said that the average is between 1 to 2% per year for LFP batteries, but I guess it depends on how the car is used, charged, and it's environment (weather, etc.) I mainly charge at home on a 4.7kW (20A) wall charger, and to 100% as often as possible.

Thanks for the video Nigel. My M3 LFP shows 260 (down from 273) miles after 19 months and 16k miles. Thats over 4.7% degradation. However, my tessie app says 4% (57.9kwh down from 60.3). I'd rather believe tessie. I've watched the cleanerwatt channel and read comments on there and it seems there is a wide variability of degradation experienced seemingly unrelated to charging habbits, with one commenting that it could be down to luck regarding purity of chemical components of the battery - lithium etc. - and i bet theres some truth in that. I personally think I'm too hung up on the subject since in the summer, i get 280 or more mile of real range on a trip. I've never reset trip A which shows avg 220wh/mile. At 58kw the means on average, including 2 winters it's done 263 miles range. I know that's not directly related to the subject but it does put things in perspective -incredible car!!!

Hi Nigel, I have a 2021 Model 3 SR+ with 55kWh CATL LFP Battery, I have 45k km (28k miles) in the car and I have the exact same degradation like you from 423km (263miles) to 400km (248miles) by now. I also read it somewhere that FIRST we will notice battery degradation caused by aging not charging. And I think the numbers prove this theory since we have the same models but aboslutely have different driving and charging habbits. The range displayed in the top right corner is calulated by a 12.8kWh/100km EPA norm used by Tesla, so in theory if you do the math you can calculate the remaining capacity. Mine could be around --> 400 km (Remaining estimated range) / 100 km x 12.8kWh = ~51kWh, and if you calculate with the original range 423km it gives you the 54.1kWh capacity as brand new which is stated to be the usuable + buffer. Since the total capacity of the battery is 55.1kWh which cannot be used 100%. Also based on my calculations if you take a look at the Energy Monitor and select the projection section, you can also calculate the capacity for example a longer drive. But here you need to add the Drive + Parked percenteges and substract it form 100% and you need to calculate with this. For me this method also gives the approcimate 51kWh. So my battery is also around 51/54, 94-95% just like yours, and in theory I can still be using 51kwH for driving until the car completly shuts down. Since the EPA range displayed int the top right corner is for the 0-100% the buffer is an additional capacity that can be used after you reached 0%. Cheers, Tom

I suspect the LFP degradation curve will flatten out for longer than NCM / NCA. We have 2 NCM Model 3s. One has lost 3% in 30000km and the other 7% in 40000km. The higher mileage car was charged to 100% a lot by the previous owner. LFP is a bit misunderstood. The BMS does need a charge to 100% on a regular basis but its looking like they last longer if its not every single time. Second how good the Tessie app is. The best out there

Try to do a couple of charges from 100 to around 10% and vice-versa, so the BMS can get an estimate of the lower end also. Sometimes it may not know the true capacity anymore, and show you higher degradation than it should. Other thing, it seems LFP's are degrading more with time than mileage/kms itself. Kind of constant rate, 1-4% year. Best to note that they degrade faster at higher temperatures, and higher SOC. There won't be much damage to charge to 100%, but don't keep it there for long, usually LFP degrade less at 70%, and even a bit less at around 60%, keep it in this interval and charge higher only when you will do a trip soon. Currently i have an Y with BYD blade, shows same kms as new but only has 2.5months / 4500km. Can't really tell how it will go. Mostly with Portugal temperatures, like this summer reaching 40C. And sadly seems Tesla doesn't cool batteries while parked, tries to keep the batteries around 38C while driving, and if you park, does some initial coolant recirculation, to try to keep the cells at similar temperature, but they will stay there until the ambient temperature lets it cool down (if it's lower). The thing is, LFP batteries at 35-38C can degrade 3-4x faster than they would be at 20-25C. So Tesla doesn't make that much effort to extend battery life against what i expected, seems they are more optimized for efficiency and waste the less energy possible, than extend the battery life some more years. I understand higher temperatures for driving (allows to extract higher power on the battery with less damage), but not for parking.

I think you should charge to 100% occasionally just to rebalance the pack being unbalanced can cause the charge estimate to be off. Charging to 100% on a journey does little harm because you discharge it again fairly quickly. The damage is more to do with how long you're keeping it at 100%. So, you don't want to keep it topped up all the time.

Well they are build to last the warranty period. You are not very smart if you believe the marketing number. Tesla warranty is only 80 000km for a reason. Nobody cares what will happen with the car battery after the warranty period. 70% capacity for 8 years. They calculated that you should lose around 4% capacity per year.

i use tessie app for record my degradation and for me after 15 months of ownership i am down from 440km range at 100% to 422km range at 100%, the tessie app tells me I have a degradation of 3.2% over that time. I have done 27,000 KM so far on the car.

Battery degredation is not linear,.you will lose most during the first year or so of driving, then your mileage will go up but degredation will stay the same meaning 1% is very accurate. LFP's are fine to charge to 100% NMC are not and 80% is the Goldie Locks Zone. Our E2008 is on 40k miles and 95% SOH and it's levelled out at that figure.

Just for comparison with a "high degredation" EV with no battery temperature management, my 2018 LEAF has 12.3% degradation after 53k miles and 6 years. That's 1% per 4300 miles measured linearly as an average. I'm sure it's still fine to charge to 100% on AC with the LFP battery on your Tesla. Charging to 100% on a supercharger is probably not a good idea for practical reasons though? Much better to charge to 80% or until the charge power drops significantly, then move on.

i have model 3 made in China with LFP batteries got my car at end of May 2021, so far the car drove 133,000 kilometer and 100% show 397, when i just got it a 100% show 425 meaning i lost 6.6%.

@nigep BTW you should keep charging it once a week to 100% because the voltage curve in LFP batteries are almost flat and the BMS might lose track in witch state of charge the battery is and results in a less range. i saw a person in a Facebook group report he only charge to 80% and his car lost around 16% and his car is 6 months younger than mine.

Recommend you to contact a real battery expert. Those EPA range values (miles and km) on our screens doesn't really indicate anything. It is a made up figure/number to calm down people with challenges with comprehension of range vs state of charge with Teslas.

Hello from Portugal. I have a Tesla Y with LFP batterie with 63.000 kms. When new it marks on 418 kms now 407kms. But... and that is a big but.... when i charge it, it charges the same kws. You should try take it to 5 or 10% and see how many kws it charges to 100%. Considering that the batterie size is 60kw, and full, it only charges 58kws. Everybody knows the car will never make 400kms in normal conditions, so what says the computer it doesn't matter. I go from Lisbon to Merida supercharger in Spain with one charge only, and iI reach there with the same batterie percentage than when it was new.

Olá Miguel. O meu é igual, de Novembro de 2022, com 45000km e tb está com 407km atualmente. Te ho curiosidade é em relação aos que estão a sair da fábrica da Alemanha com as baterias blade. Já li nuns comentários que têm degradação mais depressa que as Catl...

@@PointBlankPT Tenho um Y BYD Blade, fabricado em Abril, entregue em final de Junho, neste momento só tem 4500km, ainda é cedo para mencionar a degradação, para já mostra os mesmos kms de novo, 393km (pelo que vi, houve um update na estimativa EPA aparentemente, e desde Maio ou Junho, vêm com menos alcance marcado que os anteriores). Relativamente à degradação mais rápida, é impossível dizer ainda, essa estatística vem de um excel criado (onde as pessoas metem dados do carro), e não cobre esta alteração na estatística EPA. Eu próprio preenchi, e aparece-me uns 5-6% de degradação, quando tenho 0% para já. Lá vai mais um para a estatística a dizer que degradam mais... A outra variável, é que as CATL estão no mercado há alguns anos, e a curva inicial de degradação costuma ser maior, as BYD ainda só têm dados dessa parte, as CATL têm dados da curva de degradação já estabilizada. Espero que as BYD durem pelo menos o mesmo que as CATL.

Hi my model Y RWD 2023 is at 1.6%. I think I made an error in charging to 100% based on your loss.. I’ve done 26000km so far in 7 months. I started out at 435km now I’m at 428. I’ve now started charging to 70-80% daily and charging to 100% once a week which is what my recommendation is in the car when I move the charge slider from 100%. Hopefully my degradation starts to plateau out. To get to your level by 87000km
