How I Keep My Tesla Battery Healthy Without a Home Charger

[@dyhppyx]

This is really interesting Joy. Bjorn in Norway recently tested a 2021 long range 3 used as a taxi mostly supercharged. He found 15% degredation at only 50k miles. He theorized that maybe the driver charged to 100 and allowed it to sit there. It's kinda crazy to me that we don't have some authority scientist from Tesla that can explain what is exactly happening to the batteries. But I think you are right. Conclusions are supercharging is totally ok. Deep charge cycles are good for the bms to reset. Sitting at full or empty not good unless it's an lfp battery. I personally love going deep to 2% or less and watching the supercharger fill it up super fast. Can't wait to see your degredation after the next 50k miles. Update from me, I'm at 165k miles. Battery still seems ok to me.

[@TeslaJoy]

Incredible!!!

[@joelado]

Deep cycling any battery is not good for the battery because it changes the battery chemistry too much. What Joy is saying maybe anecdotal but if fits what I know about Lithium-ion NCM batteries. With LFP batteries they are not affected by being charged to 100%, but doing too many deep cycle can in the long run shorten their life. LFP batteries can handle 200,000 micro-cycles. So if you normally charge up your LFP Tesla to 100% and you go on a quick trip where your battery is still in the high 90s, charge it up to 100% again. It will seem like nothing to your battery. NCM batteries are much the same way, but they tend to last longer if you don't charge them to 100%. Tesla recommends 80%. I think what Joy is doing, going to 90% is just fine. Micro cycling for 5% small trips should be fine if you only go back to 90%. Tesla's batteries are known to last between 300,000 to 500,000 miles if you treat them right. Teslas are also known to lose most of their degradation in the first few years of ownership and then the battery degradation slows down as you pass the 150,000 mile mark. It will be interesting to see what Joy's experience will be. I'm looking forward to her future reports.

[@dyhppyx]

@@joelado I agree with you. Not much of all this makes sense. I'm trying to figure out what means what. That's why I wish a Tesla engineer would explain the exact behavior they expect.

[@joelado]

@@денисбаженов-щ1б This is good to know. Tesla has introducing a variety of battery form factors since its beginning. The first Model S started with Panasonic 18650s (1865) (I believe this was what you were talking about when you said above 16500). Then they went with the 2170s. The new form allowed them to remove some of the space between the batteries and increase the energy density a little. I would have thought that they wouldn't be that different from the 1865s simply because the only difference between the batteries was the form, but it seems to be making a difference in Norway your telling me. In 2019 Tesla moved to rectangular Lithium Iron Phosphate (LFP) (prismatic) batteries for the Model 3 Standard Range Plus. Again, taking advantage of the rectangular form factor to overcome the lower energy density of these safer and cheaper batteries. Then for the Model Y Tesla introduce the 4680 big cylindrical multi-tab battery whose form and internal structure allowed for two things, they allowed the cells to be built into the structure of the car for greater stiffness in the vehicle, and the multi-tab allowed for a greater discharge rate (C-rate) which helped it improve acceleration for the bigger heavier Model Y. They have recently redesigned the 4680s again so that they could get more range by expanding the amount of electro-chemicals inside the same form and reducing the size of the cell's structural elements. These new batteries will be the ones used in the Cybertruck. I would have hoped that these new form factors wouldn't have had much of an effect on the longevity of Tesla's batteries. Batteries are hard to manufacture with very exacting standards, they are hard to make safe and even though they have become cheaper, are still expensive to make. Just think about the problems that LG has had with its batteries. LG is almost single handedly responsible for most of the battery fires in EVs. It seems that Tesla has in general avoided problems at that level. (Electric cars now being produced in the millions have only a small percentage of fires compared to internal combustion engined vehicle fires) I'm planning to purchase a Tesla probably next year. I want to get the very best one for me that I can afford. This means I'm going to be looking for a used Tesla Model 3. I live in the country (rural areas surrounded by farms and woods) in that part of the country settled by Norwegians, Swedes and Fins. I'm a white Hispanic man born in Washington, DC, ended up here, in America's frozen north, because it was where my wife was born. The weather here is very cold in the winter and the distances I have to go are long. Since you are from Norway, what has been the best Tesla to buy there?

[@joelado]

@@dyhppyx The big problem, as I see it, with batteries is that they are very new between innovation and implementation. I don't think it is a bad thing that new battery chemistries and forms are being implemented fast. Lead acid batteries stayed the mainstay of rechargeable batteries for almost 100 years before real innovation and implementation started happening in the 1990s. My first Motorola Brick cell phone and my over the shoulder video camera used lead acid batteries and were heavy and huge. When we are talking about advanced batteries for EVs we are talking the oldest being just about 25 years old. Real implementation in a mass produced EV started with the Nissan, Leaf in 2011. (the Tesla roadster started the trend, but at near $100,000 that is about $234,000 in today's money) it was not a mass produced car). So, since all the innovation and implementation has happened inside the last 12 years, there is no way of knowing how all this new battery stuff will be after 15 years and beyond. It simply is too new. However, as trendline analysis goes, Tesla's batteries will last much longer than their petrol powered counterparts. Just how long remains to be seen.

[@danhoyles]

This is good tip. I just recently got Model 3 and do not have home charging. Will be 95% Supercharging mine.👍

[@TeslaJoy]

Congrats!

[@tmajek]

There are a few good lecture series out there on KZbin speaking to what causes lithium based battery degradation. Charging and discharging these batteries is a benign process and causes no harm. Whether at home or at supercharger. The damage occurs when the battery sits for many hours at either a very high or very low state of charge (say 5% or 95% charge). This causes build up between the surface and electrolyte and quickly reduces battery life. So if you charge at home to even 80% but leave it sitting there like that for days before you drive, no good. Same if you supercharge it to 100% and then leave it overnight before going on that road trip. If you need to leave your Tesla parked for long periods of time do so at close to 50% charge or near there for least degradation. At least that’s what I learned from the lectures. Best of luck everyone!

[@TeslaJoy]

Those are in theory. My videos are real usage data.

[@easternpa2]

So great to see someone else living a similar "charging life" to mine. I work from home and can't install a charger. I typically spend half an hour at the local supercharger on Saturday or Sunday mornings. I'll charge to 93 and run some errands so that I get home in the high 80s. I'm happy with my situation, although it would not be sustainable if I had a daily commute.

[@dc5]

Glad to know that strategy works. I'm getting a Model Y in 2 days and will be in the exact situation you are in. That's exactly what I was planning to do but wasn't sure if it would work. I feel more relieved now 😅. Thank you for sharing!

[@easternpa2]

@@dc5 Thank you for commenting. My local SC is about 12 minutes away and all of my weekly errands are located between the SC and my home. I would say I've never had to wait once in line, and I've only seen other people wait in line twice in two years. They will be deploying a NEVI-funded DCFC next door, so I'm doing the CCS upgrade in order to take advantage of it. Hopefully, a NACS port will be included from day 1 so that I won't need to buy the CCS adapter.

[@chriscovella1371]

Spectacular statistics. Appreciate all the info. The weather, charging and driving habits for different people in different areas are almost uncountable. Generally speaking it’s clear Tesla bms is superior to other EV’s. I’m currently trying to talk my daughter into a Tesla, giving her as much info as possible.

[@BosnianAJ]

Thanks so much for this!!!! I love my car and live in a condo luckily my job has a super charger 3 min from my location I will deff let it drain more

[@sibere2]

I believe "low" means 10% or below. 20% is fine. Remember that it's the displayed %, not the actual which is a few % higher (bottom buffer).

[@BrianPankey]

I have ~130k miles (2019 LR RWD) and about 10% degradation. Never babied charging the car at all. 58% level 2 charging, 42% supercharging. as long as it can make it from one v3 charger to the next thats all I care about. Although once I hit 100k, the 3kwh bottom buffer is no longer usable so at ~3% my car straight up drops dead

[@johnnyquid-xj4kk]

Good. I use it in sports mode.

[@lazziebardakos2956]

Great advice based on personal experience. I honestly think that for 95% of the people/cars the battery will outlast the car doing normal driving in a place that doesn't freeze in winter or experience months of heat waves in summer.

[@TeslaJoy]

Totally!

[@sonnyburnett8725]

Don’t know if these two worlds compare, but as a remote control plane user its really interesting to hear these things about charging. In rc, if you run the battery down, you should always consider temperature and let them cool before charging again. Temperature is king along with charging technique. Great video, thank you.

[@Rgdonaire_07]

I’m skeptical of this but nice that you have only 2% degradation. This is one of these subjects where everyone seems to have an advice. I charge for my daily commute at home, but I never let it drop below 40%. I may try to get to 20%.

[@maselnuss.]

It’s not about at which SoC you‘re charging, it‘s about the amount of cycles. So it doesn‘t matter charging two times from 50 to 80 or one time from 20 to 80 because you charged in both cases 60 percent in total. The fact that you shall not charge over 90% or let the battery drain under 5% , 10% or so is true (except LFP maybe).

[@TeslaJoy]

That’s what we’ve been told, but could you please explain why this theory isn’t true in real life usage?

[@AznPride85]

​@TeslaJoy Love your channel Joy! Please keep up the great content as it is oh-so helpful 😊. When reaching out toTesla, they said that the BMS recalibrates when you discharge down to 10% or lower and charge past 90%. To add on to what Marcel Christiansen pointed out, cycle count plays a big role in determining the longevity of your battery, however, other contibuting factors include rate of charge/discharge, battery temp, ambient temp, and frequency of usage. Someone charging everyday with the battery between 30 and 80% won't have the correct capacity/range displayed until the next time mertics mentioned earlier are hit for the BMS to recalibrate. In the meantime, the capacity/range displayed is misleading and would suggest greater degradation than actual. If you look at the graph Tesla released not long ago for vehicles of much higher mileage, you'll see the median line begins to flatten out as the miles pile up. In the end, as long as your getting 75 to 80% of original capacity after 200k miles, you're in the ballpark. Most even fair better than that. I would not stress out on the minutiae. Rule of thumb is to not leave your vehicle at a very low SoC of 10% or less for extended periods of time and likewise for high SoC of 95% or higher as this can damage your battery. It's easy to remember how an NMC battery should be treated, just think of our own body. We like a temperature that's not too warm or too cold. We don't like being hungry, or God forbid, starving. We are uncomfortable if we're too full. Hope this helps put your mind and others as well, at ease. May God bless you and keep you.

[@johnnyquid-xj4kk]

My 2021 YM gets up to 298 at 100%. Depending on the temperature it seems to stay around 296-298. Lowest I’ve seen is 294 when it’s really hot over 100F. You pretty much stated it all.

[@arielrommelbriones8948]

Great information and very informative but i disagree on one thing I don't think is not a good idea to keep draining below 20 percent I think 20 percent is a good idea and I'm curious I think you guys have lfp battery better chemistry than the 4680 lithium ion battery for the the model y and Tesla recommendation is 20 to 80 percent only except road trip going 90 percent all the time could hurt the model or the long range model 3

[@TeslaJoy]

Make sure you watch my video on how I keep my battery healthy with over 95%+ supercharging.

[@alanrcrews]

Miles are so variable, confounded by so many factors! Full charge is a stationary target, confounded by much fewer factors.

Just like a car that needs gasoline/petrol one does not need to constantly refuel/recharge until either a long range drive is anticipated or the remaining miles/capacity is low.

[@yskwong]

Daily plugged in charged up to 70% on my Ioniq 5 Daily commute average down to 52-55%, so I top up 15-18% daily, always plugged. Only DC charged 4 times total. Charged up to 100% only 6 times, and twice, was at Hyundai SC for calibration and measurements. 18 months, 37k km, 0.1% degradation according to Hyundai.

What about for those who can’t install a home charger?

[@yskwong]

@@TeslaJoy Well, DC external DC is the only way to go, I guess? In my country, Malaysia, we have a subscription to a network call ChargEV, and for most 11kW and below, are usually free if you pay the annual subscription of USD60. The closest ChargEV location is about 1.5km from me, and I used to drop it off there, charge it, take an electric scooter from the back of my car and ride home. But ever since I've gotten a wallbox installed, I didn't bother with it anymore.

I live in LA so there’s no snow here. However, in winter time you will see more energy consumption which is normal for all EVs. When the weather is 30°-40°, my charging habit doesn’t change but I might supercharge more frequently due to colder weather battery drain. Hope it helps!

[@tonbodragonfly]

Just wondering: how did you measure this degradation? Could it not be that these 35 less mile could be caused by colder weather or perhaps a different style of driving?

[@CoachBorne]

@tonbodragonfly by doing the equations of miles available vs %, and then multiplying by 100%. After subtracting from 303, which was my original milage! I live in North Texas, or Dallas/Fort Worth... we really don't get cold here.

[@tonbodragonfly]

@@CoachBorne Thanks! We drive a kona electric 64kWh for just over 4 years. Bought in April 2020 at which time it drove 475kms on a full charge. By january the following year it did 415kms on a ful charge. Our temperatures range from 4°C in winter to 34°C (some weeks) in summer. Now, at the end of May temperatures have climbed to 20°C and the range has increased to 455kms and still increasing. If I were to calculate degradation it would come te less than 5% but it would be 13% if not allowing for other (season) parameters.

[@thirsty3333]

17% degradation on 2015 MS P85D 50/50 home and super charger 256k miles on her now FYI I drive everyday I charge everyday driving to work is 120 miles round trip

[@Fear.of.the.Dark.]

the range display in the drive screen is not really an accurate measurement of battery degradation. It is important to see what distance you see in energy consumption view at the average rated power consumption (around 250kwh/mile for model Y for example) to gauge this and see whether you get realistic range for 280 to 290 miles in long range model Y for example. Personally as long as you avoid the bottom 20% and the top 20% of state of charge you will be fine. More important to keep and use the middle portion of the battery state of charge so if your daily commute and after work leisure drive can be done with 60% charging limit, go for that instead of charging to 80% for example. Also use scheduled departure charging and pre-condition if you have home charger so that your car finishes charging before your actual commute begins.

[@TeslaJoy]

New research disputes that as I mentioned in video.

[@Fear.of.the.Dark.]

@@TeslaJoy disputes which portion? Can you provide link? I have zero degradation over 20k miles now with my model Y long range with my charging habits. I get around 290 to 300 miles range with 260 kWh/mile efficiency.

Your car is still very new. What’s your battery capacity now (not miles as I mentioned)? Make sure you watch my video of a car that had 155K miles with 100% supercharging.

[@xXxM4nuxXx]

Interesting conclusion. I think that the biggest factor on battery degradation is overheating. When you charge more often with SC you stress the battery with high temperatures more often. Other stress factors are keeping your car parked with the battery below 10% or above 90%.

[@xXxM4nuxXx]

@@jacobheinz8236 I know what is in manual but that is not generally valid for all cases and from my point of view is more a misleading statement. This make sense only if you have sentry mode enabled which consume a lot of energy while stationary and to avoid dropping the SoC below 20%. The lithium ion batteries should be maintained on long term between 30-50 percent, the discharge rate on tesla is between 0,5-1% per day with sentry disabled, so you can leave it also 1 month without connecting to a charger.

Not a tesla owner. I live with my EV for 3 years and ~65000 km Original capacity is 42 kwh, and range is 160 miles (263km) Due to the public charging situation, having a home charger was a prerequisite for me. I now use the granny charger daily. It runs at 13 amps over 240 volts so I get about 1.8kw/h My daily commute is 80 km and that power is enough to charge half the battery overnight, so I almost never reach 100%. My car doesn't have charge limiter, so it's always a guessing game. I don't know how degraded my battery is as the car gives no information at all, and my OBD2 port doesn't work. My car supports DC charging up to 50kw/h and I have done that about 6 times so far... I aim to drive this car for another 2-3 years and then get a used model 3 with LFP battery.

Thanks for your video. I recently got a Tesla Model 3 2024 with long-range capability. Tesla recommends keeping the battery charged to 80% when not in use, and I've been following this guideline.

Despite following Tesla's recommendations, I have a lingering feeling that this approach might not be ideal. I've tried researching but haven't found any helpful information.

As you own an Model 3, to my knowledge, this model have 2 type of batteries as I know it now, LFP (Chinese BYD) and standard Li-Ion (Panasonic if I remember correctly). The 2 will not degrade at the same rate (Less for the LFP compared to Li-ion). What I notice too, you rely only on one application (The car app. I think ?), then you have no confirmation if it's the reality. Why I say this? If you have a Li-ion battery? Normally this battery love 50% charge, but it able to go to extreme but in counter part will degrade faster as more extreme you go. (It's what you suggest exactly and normally it's must do the opposite as you say). The advantage to go to the extreme is normally the battery will calibrate it's full charge at those times.(Your estimate available millage) with those extreme you do. What I'm curious to see to more confirm your theorie and it's easy to do without other machine. It's to do a range test to see if your estimate range is the reality. My suggestion, your estimate will be based on previous travel, keep same kind travel (Weather and on the highway without wind) and you will have your answer if it have lost only 2.x% compared to a new one. From a guy that joined the bellow 0% club that now know sometimes, the car estimate is really off. LOL.

Hi Sergio, if you watch the 155K mile video that I shared when I interviewed my friend, you would find that both his Tessie app and my Stats app essentially show similar data, hope this helps.

[@kautilya21]

My degradation is 6.2% after one year and 25K kms. No supercharging, only home charging 20-80%. Very high IMO.

You’re probably charging it to 100% all the time

When you say you do almost 100% “supercharging” do you mean at Tesla superchargers or just any public EV charging station? My work has EV chargers but they’re not superchargers, but I wasn’t sure if our definitions were the same.

Hi..one question, i have MY LR,i dont hv level 2 charging at home and i rely on 110v charging and it's fine for my daily commute (approx. 25 miles /day). My confusion is to how often to charge. I currently charge it everyday till 70%( ABC). Since i dont hv level 2 at home,i dont want to have range anxiety so i charge till 70%. What is your opinion on charging mylr everyday till 70% using 110v charging?

[@TeslaJoy]

Hey you should be ok with slow charging!

[@fdeguilla]

Only have less than 5000 miles on mine so I have no real world experience yet but according to some lectures that I saw, from people who designs and study the subject about batteries, EV Battery Health with Dr Jeff Dahn Dalhousie U, and also info from Battery University, “operating between 70% and 45% majority of the time is ideal”.

[@TeslaJoy]

That’s in theory but real world data and usage, as you saw, is quite different.

[@fdeguilla]

From what I understand, this depends on your battery composition and good luck on finding out exactly what you really have.

[@TeslaJoy]

Please also watch the video I mentioned with a Model 3 that only supercharge for 155K miles.

[@dsvillalva]

Interesting video Joy. First off, you’re absolutely beautiful. Just sayin’. I have the dual motor long range with 19” rims, it’s about the same age as the Joymobile with similar total miles. At 100% I’m showing a range of 282, so that’s on the lower side. I upgraded to the acceleration boost 4 years ago when it was first offered. My charging has been level 2 for 99% of the time, and mostly charging from 50% to 90%. I’m in the Northeast. I wonder if the acceleration boost drops the range, and also the hot summers/brutal winters in the Northeast plays a factor.

[@TeslaJoy]

Make sure you watch the whole video. 😉

[@djozzmosis]

So i charge at level 2 at my home, may daily commute is 70miles, most of time i charge at work at around 50-60% and at home also similar 50-60%. So when its charged i only charge till 60%. So with lvl 2, is it better ti let drop till 20%.

[@TeslaJoy]

I think it’s good practice to let it drop to 20% before you charge it back up once in a while.

3:19 11.5% degradation after 5 years and 178k miles.

[@Chainyanker007]

With all these variables regarding charging a Tesla, including Tesla’s recommendation to keep it plugged in if possible. Here’s my situation: ‘20 model S LR+, with 18650 batteries, free SC charging for life of ownership, I have solar panels with net metering and TOU rates thru SCal Edison and a 240 V NEMA 14-50 plug in my garage. I used to mostly charge at home because it’s so easy (5 sec to plug in) and often left it plugged in to 80% charge, usually too lazy to drive 5.5 miles to a 72 kW SC station. However this changed this last March when a 250 kW 24 stall SC station open up just 0.3 miles away, lucky me. So now about 75% of my charging is at the SC, the rest at home. I no longer leave it plugged in at home. What if anything should I do to change charging practice? I figure about 2.5% degradation based on battery mileage, but probably inaccurate. I’m retired so annual mileage is < 7500 miles a year. Anyone got any good suggestions on what would be a good charging practice for my situation? Usual charge range is 30% to 80%, sometimes down to 20%.
