100% Charge for 16 Days Straight - 💯

I charged my Model Y for 16 days straight to 100% to see what happened. I found out that you can effect the battery in a good way. And supercharging may harm the battery.

[@joetripp123]

Thanks Brian for always pushing the envelope for our gain. "Use your car" - best advice ever. I never worry about the miles at a given charge. Actually I leave it on % and don't even track it. After 2.5 years and 33,500 miles I just checked TeslaF's battery degradation report and it shows i went from 309 at new to 305 today. In the end I feel much of the mileage numbers are a guess-o-meter.

[@smartelectriccar]

Have charged our 2013 Model S to 100% hundreds of times. Routinely once per week. Still at 95% original range !!

[@SUPAPUCH]

As am I. Another Chris S, lol

[@ItsKimJava]

Cool editing with the 16 days. For what it’s worth, both the battery engineer and Elon made it appear as though long term degradation was only an issue if your car sat above 95% SOC for extended periods. So as your video shows, the frequency of high SOC charging doesn’t seem to be as bad as leaving it at that higher level for extended periods. Bjorn in Norway is a great example of frequent supercharging and long term health issues, this is also clear by tesla capping charging speed for frequent users of Superchargers.

[@scottysize]

I didn't even think about the heat. I've seen both of your battery videos. Thanks!!!!!

I have a tesla model 3, i have been charging it between 40-60% and I recently charged it to 100% it should say 560 km as its from 2019, but it says 467 km i asked tesla service center here in Denmark and they said that i can bring it in and they can look at it, but if nothing is wrong then i have to Pay and they think nothing is wrong.

[@MTNRanger]

You really should be using "Scan My Tesla" and "Stats" apps to track the battery. The 269-273 are all just rounding errors when the car is calculating the range from the BMS based on the EPA numbers. To do the supposed "BMS reset", you need to get down to 10% and then charge up to 100% - do this several times. Just charging up to 100% everyday for two weeks will not do anything.

[@TechTesla]

You don’t need to go that extreme... 80% down to 30 is more than enough. Even just an hour drive on the highway will help. Remember the BMS calculates is capacity estimates by tracking power drawn from the battery. Charging to to top only forces cell balancing, which is not an issue with 3/Y

[@MTNRanger]

@@TechTesla My car has been trending downward for the last couple months. When I charge to 75-80% my range tends to drop to around 292 miles on my LR RWD. This summer, I kept it around 50% and my range started increasing to 300-310. I've been driving more now and need to keep it above 50%. I've done a decent day trip last week and that didn't help. I'm doing the "BMS reset" this week. I'll be doing a video with my results.

[@TechTesla]

@@MTNRanger The warmer summer temps certainly help range estimates as you use less energy when driving. One trip is not going to make an instant large difference. It's more about regular highway driving vs sitting around all year with a few local trips to the store. If you had your battery balance in front of you like I do, you would see that Tesla has done an amazing job at keeping the 3's battery always well balanced through most charging situations without the need for high percent charges.

[@scottysize]

My Model 3 did the same thing. It started at 307 the first time I charged it when I got it. Then it dropped to 299 after 20,000 miles. Today after 69,000 miles, it's still at 297. Tesla said this is normal and that they anticipate a dramatic drop at the beginning, then a slow steady drop after. Those who are still getting 307 after 70,000 miles are just lucky.

[@johnhagin4890]

I have found over 2 years with my Tesla 3 AWD 2018 that charging temperature had a very big impact on it. Charging to 90% in the summer with temperatures 60 to 90 degrees the miles are 279 to 282. In the winter charging to 90% with temperatures 30 to 50 degree the miles are 273 to 277.

[@TechSpyYt]

This test was pretty useless in my opinion. The range increasing and decreasing was just some software calibration issue in my opinion. Just a re calibration would fix it I think.

[@realapproved]

[@i1Tesla]

Thanks 👍

[@jaymarclucas3560]

So...I have a 2018 Performance Model 3 and I’m actually “guilty” of charging my car to 97-98% which, initially, outputs about 298-302 miles every week and half to 2 weeks or until I get down to about 10-12%. Since I’ve had my car (October 2018), I’ve probably charged at the supercharger about 90% of the time. I usually only charge at home if it’s an emergency situation or out of inconvenience (bad weather, late night, etc). My maximum output now at full charge sits at about 294 miles. I haven’t changed the “stock” performance wheels nor have I modified my car by any means that would increase or reduce the efficiency of the car’s overall performance.

[@Vintage_Dave_T]

There was a guy on one of the forums that re-trained his BMS to know what range he really did have. He did this over several months charging and depleting his battery systematically to certain levels. Model Y got about a 10 mile software bump a couple months ago. Not sure how many of us saw an instantaneous range boost.

[@bryanmerton5153]

Super. Video. I have had my model 3 since February. Full charge for me is 312. When I charge to 90% daily I get 270-274. When I charge to 90 when I am around 20 I get between 280-287.

[@RyanBrosnahan]

I drive my 3P a lot and after 2 years and 60k+ miles, I have about 10% degradation. Recently, I have been always charging to full because several days a week I am driving 150-200 miles on short notice. Without a full charge, I am often forced to supercharge to make it home. My effective range for mostly flat highway was a little over 200 mi when the car was new, and is now a little under 200. It is disappointing that the EPA testing protocol does not provide a very accurate mileage estimate for real world driving.

[@mysurlytrucker7510]

I notice the heat making a significant difference really heat your garage up with obviously your car in it ,the cold makes such a difference, like i never charge my lithium batteries straight after use, i heat up to a good temp first , it works and its important to really use the battery right down sometimes make sure its at a comfortable temp get your garage to 70 degrees overnight then charge your car in it .

[@carmp3fan]

What about using TeslaFi to charge to 100% and then turning on max heat long enough to take it to 90-95%?

[@gust9464]

Thx Brian. I have battery degradation on my performance model (about 7 %). I also spoke with Tesla engineering & this is what I was told...Power off the car from both the scroll buttons & then the power off button. Then drive the car until 10% to 20% & fully charge to 100 %. After that, charge to 100% every 2 or 3 months. Per “Tesla”, this should restore the battery range. Let’s see 🤔🔋

[@leaflover3497]

What is recommended for those of us that aren’t driving very much these days? I’m not going into an office anymore and with most things closed we’re not traveling. Realistically I would only have to charge one every two weeks. Is that bad?

I think for the range calculation to get reset you need to drain it down low as well.

[@John-209]

Did you get it nice and low around 10% any of those times before topping it off?

[@Jerrodkowalski]

I just Did a charging set to 100% and below 10%, I do it Quarterly. I also Had some bouncing around at the top end by a few miles but I went from a low of 289 to a high of 297. Two separate apps show charts of the change. I will Be curious about the weekly test, for sure quarterly is a good start. I have a 2018 model 3 LR that started at 310 and boosted to 320 when there was an update in 2019. It trended down after that over time. 296 from 310 is 5% drop after 33 months and 37,700 miles. Not bad at all!

[@jakesta11]

You can pour water the same rate to get to about 98 percent of a glass... Pushed analogy :)

[@Luke_Donald]

Hi Brian, thanks for this interesting video. I think you should teach you BMS also the 0% point, otherwise how should it know the capacity if only 100% is known. It should know both limits. Please try to ride the battery down to 0% (or even below) and than charge slowly to 100%. I think this will really recalibrate the bms and bring back miles :-)

[@thomas8421]

I have a early performance model y with 3500 miles on it and it only shows about 270/ 272 same as yours. I've only supercharged it one time and never really go to 100% so I think it's more a software management thing.

I have a prius prime and I'm noticing my range drop, because the heat is running more and I'm driving more with full headlights. see if your displays reference a statistic for Miles per KWH. about months ago (October) i was getting 4.9 miles per KWH and 32 full range on the battery (plug-in hybrid, not electric only). now, with the colder weather (more heat usage and headlights) the miles per KWH is 4.5 and my full range is 27-28 miles. I do charge everyday, during M-F it is scheduled for 6:30 and i leave for work between 7:30 and 8 and drive on electric only to start. bottom line look for that stat of its available and do a comparison on that.

I have a 2018 model 3 long range... they recently did a service and it requires disconnecting 12v battery... in within 4 weeks after the service I noticed I was losing range fast... down to 260 fully charge... what they found out was the 12v battery was loose.. after They tightened up the negative side battery, i fully charged my car that night...and it went up to 270... Everyday as I charge it would go up to 5 more miles.. Finally it cap out to 298 @ 100% charge... ... just a thought

To calibrate you need to do a few 10 - 100 % rounds.. 70-100 doesn't do much in terms of balancing..

Hi all. Wondering what the model 3 range meter says on the SR+? How many miles at 100% when new?

[@christopherrasmussen4732]

are you pre conditioning battery before fully charging?

[@fiveangle]

Time spent at 100% SoC is similar to reactions that occur during normal charging, e.g. it stresses the battery chemistry. It is best to minimize time non-exothermic charging as well as time spent at 100% SoC. From laptop and smart phone data, we already have ample data on this: if you do this for approx 2yrs, the battery will have degraded to approx 80% of original capacity even if not having used the battery at all.

[@1680bo]

What did you run your SOC down to everyday?

[@paulhansen8052]

It definitely does re-train/rebalance the battery. I've done this several times since taking delivery of my 2018. I have a CANBUS OBD reader I use and when my range starts dipping into the 280ish range (new was 310) I'll stop daily charging it to 90% and charge it to 100 for a week or so (not daily charging though) and I'll generally bounce back to about 300 miles of range with about 40k miles on the car now.

[@loriwright6231]

I have an early 2018 as well. I had no loss until April of this year. I had not driven it for several months due to the stay at home orders and working from home. When I got in it to drive my max was 286 when it was 311 sometimes 314 when I would fully charge for trips. Im not understanding what you did to improve your charge? Just charging it to 100% once a week?

I think to recalibrate and get your miles back you should try 100% - 5%. That is considered to increase your battery range if it's degraded. I think you already know this though 😀

[@topics1463]

Thoughts on the cybertruck?

[@Basta147]

Degradation is the most at the beginning and then goes really slow. Statistics show that Model S from 2012 have in average still 90-95%(!!) of total capacity. I can confirm that with my P85D 2015 120.000km, I have still around 94ish% left. :)

[@ClintonWeiss]

Several months later now, are you still charging to 100% once a week? Did your car's battery capacity increase at all?

[@TechTesla]

As I’ve been saying charging to 100% will not increase your range capacity estimate, and you just proved it. The range estimate is calculated after a long constant drive... drive for an hour or so on the highway (then rest for half an hour). Do that a few times. We’ve all being seeing our range estimates drop because we’ve been stuck at home for 9 months not driving anywhere.

[@vitale1914]

Interesting test. Someone correct me if I am wrong, but I don't think your total mileage reflects the capacity of the battery that is showing on that screen. What it's telling you is that the projected range you should get by driving the way you drive. In fact I think it is actually on the generous side considering the way you drive! Please don't misunderstand me, I'm not trying to insult you, but as you know, the faster you drive the less efficient your car will be. I think that is only a 'guess-o-meter' (gom). Try this, for one week do your best to keep your w/mi down to 250 or lower. I will bet your full battery range (capacity) will greatly increase. The car learns you driving habits and the 270 figure what it 'thinks' your range should be. I had a chevy Bolt and I found this to be true with it. I now have a MY. Like I said I could be wrong. I haven't tested it yet on my Y. It only has a few hundred miles on it so far. Try that test I would love to see the results...

Great video. Here’s the math: 290 x .70 = 203.0

[@awo1fman]

People keep talking about rounding as though they had a clue. A "rounding function" is a rigid calculation and will always give exactly the same answer given the same input, so no, it's not rounding. It's due to the fact your battery pack is made up of thousands of individual cells, all of which are constantly at slightly different states due to the BMS trying to level them all and maintain their health. The different numbers are real, normal and inconsequential.

[@arnold_2523]

Great vid! Want to kill your battery do a day hammering on the german autobahn 😔 i got already 7% degradation on my SR+ most degradation was after autobahn hammering.

[@Francescawine]

On lead acid batteries to get long life you keep the battery from getting low is apply trickle charge at 2 amps to get 100%. I got 11 years life of a 3 year battery . charging at 20 amps or more to get to 100% will shorten the life very fast. I have Telsa 2021 model 3 using 120v at 12 amps to 90% never below 70% will not heat battery to cause degradation. When using 240 v at 32 amps does get the car charge up faster but more heat to the battery. Using super chargers at 250 , 120 amps will eventually cause degradation because of heat will shorted the life. What good about about the telsa battery is that ampere maintains power even at 2 % Where lead acids battery drops amps 60%. I plan to used 120v when I do stay home. Also have 240v rated at 50 amps for a quicker charge. When I need to used supercharger for trips. Francesca

[@perandersson3356]

Did you test to heat-up your garage to 73 ?

[@JHuffPhoto]

Dude quit obsessing over it. The BMS is just taking a best guess as to the range displayed. I just turned the indicator to % so I wouldn’t obsess over it. I occasionally check the estimated range in the Stats app to make sure nothing has gone horribly wrong. I don’t do very much charging at Superchargers and most of the time keep my battery between 20% and 80%. However I do not hesitate to charge it to 100% when I need to.

[@Franklinsone]

I pushed mine from 270 to 290 by taking it low, sit over night, charge to 100%, and sit over night. After doing it 3 times I was up to 290. Still not to 310 as what I had until hitting 12k miles where it nose dived to 270.

[@michaelelliott8350]

Supercharger bad for the battery? Not sure the test results supports this conclusion. Perhaps "A Supercharger won't charge the battery to fully 100%" is a better conclusion. Using your cup analogy, it's a lot harder to restrict the flow from a fire hose (the Supercharger) to fill the cup that last small bit - so the BMS probably cuts off the Supercharger earlier. All these results fall within 1% and testing accuracy is limited by measuring device accuracy - which in this case is the Tesla software/sensors - which only report whole numbers. And we have no idea whether it is rounding up or truncating. So is 270 actually 270.4 or 270.9 vs. is 271 actually 271.0? Just some thoughts.

[@MM-bw1lo]

Ok, so you purchased the vehicle in March, I dont know if this is Long Range or Performance but LR is rated at 326, from driving, trips, etc its now at 269-272 in less than a year?!? That's like 57 percent loss of battery performance, if you do the math. Maybe this is Performance, owners should really put that in the description. So if you drive about the same in 2021, your battery would barely be in the 200 range (hypothetically) that's crazy.

You only did your test for 16 days, which is about one third of the number of days recommended. But it's all confusing.

that cup looks filthy...I hope you're not drinking from it.

[@nroose]

Seems like you are conflating health of the battery with accuracy of the range calculation. The health of the battery will be better if you charge slowly and not all the way up. This is because those things exacerbate the dendrites. The accuracy of the range calculation will be better if you at least some times drain it low and charge it high. This is because the range calculation is based on the voltage, which only varies in a small range anyway, so going all the way down or up lets it calibrate.

[@irandude1655]

So was this an LFP? I was told that I am suppose to charge it to 100 percent.

[@i1Tesla]

No they are the 2170 batteries. The LFP you can charge all the way all the time. These should be at 90 or less

[@PhongNguyen-nz9kz]

[@peterball8241]

Surely if you make the car less aerodynamic the max range will drop, not a battery issue, more a roof rack issue.

[@benjamind7290]

This data (miles remaining) includes a bias to compensate for the long-term average efficiency of the driver & car, so I'm not sure you're really measuring what you think you are measuring.

[@carmp3fan]

The range doesn’t account for driving habits. That is a simple calculation of rated capacity/rated watts per mile. On my 2019 Model 3, it’s rated for 270 watts per mile at 65mph. For an 84KW pack that’s 310 miles. The graphs under the Energy app do take average watts per mile into account. There is a page on Tesla’s website that states this but I’m on my phone and not willing to look for it right now.

[@benjamind7290]

@@carmp3fan There's more to it, because rated capacity / rated kw/m is a static number. This number isn't static, it goes both down and up.

2021 Model Y 90% is at 272 miles

[@raymondcleung]

What if "you just charge it on supercharger"...

[@jdoubleu1483]

Make sure you go below 10% as well.

[@cypvh74]

That’s all just urban legend and doesn’t do sh!t.

[@jdoubleu1483]

Urban legend or not, I did it on my Y and my range showed 280 and then went to 310. It worked for me.

[@TeslaModelSPlaid3799]

[@mikeday3198]

Kim was referring to the new China model 3. Tesla recommends charging The New China Model 3 to 100% at least once per week. Kim says they still charge 70-80% nightly and 100% every 2 or 3 months

[@benjamind7290]

No.. only the new MIC M3 with the LFO battery is 100% every time. All the others are 100% "once a week".

[@jamesharrison2068]

$4000 total or $50/month I like driving. Like you, i would pay for lane change (for me $1500). No way would i pay big nos. For autopilot.

[@bomani699]

You don't know how this works do you. Just like in a ice car the computer calculates your distance off you last driving habits before you fill it. This is the same for the tesla changing if your racing around all the time it is going to.tell you how far you can go based off the driving habits between charges

[@John-209]

Hey Brian we’re talking about two or 3 miles difference the computer looks at the amount of energy and guesses how many miles it will go I think there’s nothing wrong and it’s not confused if it stays within a few miles that right. I know my model three lost 5 to 10% of its range in the first 10 K miles now has not lost any more for the last 30,000 miles, and I think that that is the norm more times than not. Good luck buddy best looking model Y I’ve ever seen

[@Mike_Malloy]

As of today, Tesla's advertised rage for a Model Y is 326 and you're only getting 270? That's a 55 mile rage loss in under 1 yr of ownership, that's a lot, imho. :/

[@scottbreseke716]

When Brian got his 2019 performance Model Y, the advertised range was 299 I believe. The most battery degradation is in the 1st year. It's not supposed to degrade much in any years which follow the 1st year.

[@johnl1945]

Thanks for your content. Really like it. Yet, in this case? You do realize you could’ve given us the most important information in about one minute?

[@iPhil77]

204 miles is 70% limit for a 290 mile range.

[@laloajuria4678]

203. math is hard.

[@teslafudge1585]

"Not good for it" does not really factor in the short term (16 days). That number is provided by the software. They are taking a few things into account to provide you that number. Oh, and Tesla lies. ;)

[@andysccs1]

Instead of using the range, try using the battery % to see if it says 100%.

[@i1Tesla]

The car says charge complete when it is done.

SUPERCHARGING DOES NO HARM TO YOUR BATTERY 🔋

[@marvmoder8628]

You will lose regenerative braking if you go to 100%

[@kevinalmeida7159]

charging the battery to 100%is hands down scientifically hard on the battery! the BMS has no correlation to the battery health, the health is determined by battery temp and cycles. the BMS can lose calibration of the battery with routine good battery practice but this does not affect your range. example your driving habits estimates 270 miles well in 6 months it says 265 its because the BMS monitors how you discharge battery if you drive it like a prius it you might get your 270 back and not only that if you want to recalibrate your batery you must 0 your battery as well so take it down to 0 miles then to 100 and you will get the best recalibration you can do and doing this 1 time per month is all you need to do to keep it close to accurate. but note this is fine and good for BMS this is not good for battery. so lets not think the 2 are the same. whats good for 1 thing is not good for the other!!! just like health food is often viewed as healthy well yet it may be a little bit better than other foods the health food still kills you like all other food and to much health food make you fat. the best practice gives you the longest life

[@ourstate100]

it will adjust to your efficiency over time... so the last months of high consumption is likely what is being reflected in range loss. you CAN NOT test capacity like this.

[@stlufred]

That's a long read, but have you ever read that thread? teslamotorsclub.com/tmc/threads/how-i-recovered-half-of-my-batterys-lost-capacity.204712/

[@Tom-zp4xp]

Most likely your range has probably been affected by your roof rack and lowering your cars aerodynamics

[@teslakiller6959]

I think it is more important to get it lower, than to charge to 100%. So if you charge 70%-100% it is actually worse for the BMS, as opposed to 10%-90%. You also have to let it sleep and not use sentry or apps that keep it alive. I think you should try another tactic, people seem to have good results from this one - charge 10%-20% to 60% (set the limit to 60%). Do that for 1 month or 2 if possible consistently. THEN charge to 100% and see if you have any advantage. By the way, Teslas don't have any top buffer (at least until the 2021 model in Europe, but this is a whole other issue I cover on my chan) - they charge to 4.2V at 100%
