Tesla Battery Calibration | Myth Busting | Does it Really Work? | No | 

2019.32.2.2 did not change my extrapolated 100% range yet.

You just need to calibrate

I was told by a Tesla mobile ranger that Tesla in a recent software update had reduced the FSOC levels to protect battery longevity, had you heard this? My current FSOC on my M3 DM LR is 295 miles down from 310. Your thoughts?

@@jimhammond4963 I don't think so. Tesla can't sell us a car with 310 miles and then release an update to take range away. There was some controversy of this happening with older Model S cars, so I think the tech confused it for that.

Enough with the recalibrating! Lol The Tesla battery manufacturing process or any manufacturing processes will result in fluctuations in total battery energy volume. You’ll never have 2 batteries that are exactly the same. I at least appreciate the honesty in the software telling me I’m maxed out at 302 miles and not a fake software showing me 310 cause I paid for 310. Just my $.02

Very interesting. Thanks for sharing.

Can confirm, this still works in 2024

@@ChiefLunar 3 years ago I swapped my Model 3 for a Model Y. I have stopped caring as much about this as I did when I posted this comment 4 years ago, but my Y has never had anything close to the "normal" range estimate. I don't mean actual range, I mean displayed rated range. My current 100% estimate is 285-290, which is about what it has been from the start. I have not tried to re-calibrate in a very long time. Maybe I will just for the helluvit.

😂 I literally thought that after I said it

Don't forget to step out of the car with you right foot first.

@@andrecarvalho9637 Dang. I just knew I was forgetting something important.

@@andrecarvalho9637 which one is the RIGHT foot then?

Same here, feels a bit more like charging my phone that way

Jim Adams this is a great idea. I will try it now. Charging it to percentage. Just as long as the model 3 battery doesn’t behave like my iPhone battery. That shit stresses me out. Thanks.

Unfortunately the next super charger isn't 30% away it's 100 miles. It's unfortunate to lose any of the max range, especially on a long road trip.

I find percent way more stressful! I like seeing that I have a 100 miles left. I do not like seeing my battery at 30 some percent.

Yep. Same. Feels more natural too, like a cell phone

Thanks a ton! Enjoy the Y!! It's amazing

@@DirtyTesla it is amazing. I love it. I know I’m probably worrying prematurely but I moved my wifi mesh module closer to the garage which increased my wifi signal in the MY to see if that was holding up the software. Now I have a full strength signal. So far it still hasn’t shown up but I noticed when I get in the car it takes a few seconds while the car wakes up before it connects to the wifi. I assume that’s normal and not anything inhibiting me from the software upgrade. I have my setting in the car on “advanced”.

@@donaldfilicetti1640 yeah it takes a bit after delivery to start getting updates. And there's normally a few main versions floating around :)

But I don't get millions of views maybe I need to go to the dark side

Woo congratulations 🎉 and thank you so much! What config did you order? Let me know when you get it :D

@@DirtyTesla just a modest SR+ and took advantage of the free upgrades so got the red with 19 inch rims (not sure if the range loss is worth it, but frees free!)

@@jessegoldberg1679 woooooo free stuff! Congrats again. I see you in my app :) Also, nothing modest about an SR+ still a killer car

Congratulations 🎉 and Thank You for using my code! What spec did you order?! It's gonna be awesome!

Dirty Tesla I ordered the standard range, white, aero wheels, with fsd. After much debate we decided we didn’t need to spend the extra $ for the long range.

Easier than post :P

Exactly!

There is some merit to it, though. When people charge to about 70/80% daily at some point the battery will "unlearn" the total capacity and report less mileage (less kWh). Charging to 100% is then recommended and will&could help. This is even in the book and has been explained on a few occasions. Tesla could also reset the BMS manually.

Automatet but not active, those bms are passive, meaning they only top balance the pack while pluged in and sitting at 100%

@@1kruxi With the LEAF the premise that balancing only occurs at 100% was defeated when LEAFSpy Pro came out. It became clear the BMS was shunting voltages between cell pairs while the car was being driven and/or charged. This continual balancing never stops while the LEAF is driven or charged. How does Tesla balance? No idea. There is a version for LEAFSpy available I believe for S/X cars. If anyone has data from that pls share.

@@marcusbiller867 Charge limit is part of the equation. Also to be considered is that depth of discharge helps the BMS keep itself calibrated. If one only does short journeys and keeps the charge limit to 70% the BMS can get very confused. This happened to Kim of LikeTesla. I too charged to 70% but never saw the huge discrepancies that Kim did. The difference is the fact I drive anywhere between 80 and 120 miles each workday.

"accurate at 10%" is a great point

"The only card that matters is the last one you turn over"

I got you 👍

Yo teeth be flossin!

there will absolutely be degradation. Batteries degrade over time, not just charging cycles.

It is software. The 284 is just a guess. I have 35k miles on mine. It has shown full charge estimate as low at 280 miles. I hopped in my car and drove from Park City Utah to Elko Nevada with an average speed of 78mph (cruise control 88 on 80) and made it no problem. Just use your nav to get to the next charger and don't worry about it. You did not lose that range, it just looks like you did. After a couple weeks of topping off in the am to 100% when going on a longer drive, my rated range is now 297 miles. Showing 284 miles or 297 miles doesn't change my ability to get to the next supercharger at all...

You will degrade ~5% the first year and then slower after that but continual degradation. It is chemistry. You didn't pay for a magic never degrading battery.

Scott Fauque So does the loss of nearly 10 percent of rated range and even more of actual range in 8 months somehow "magically" negate my argument or comment? So at what point can I comment and have you at least acquiesce that there might be a legitimate problem? Is 15 percent of loss in 8 months acceptable ?

Mr Toad's Wild Ride yes, because it is phantom range loss. If your battery is actually bad, Tesla will fix it. My car say at a lower “estimated full charge” for well over 10,000 miles before it went back up. Slide your soc barb a little to the right if you need to. But seriously just drive your car.

It happens to only long range rear wheel drive vehicles, but then some lost it in future updates so... It's strange lol

It will fluctuate. Save yourself the headache and change to % lol

Nope, Tesla says the displayed range is not related to driving habits www.tesla.com/support/range

Nope

No it doesn't change based on driving habits.

No, rated range is fixed number based on kWh available. kWh/15 gives you the mileage range in the monitor.

@@DirtyTesla Well this guys says it does ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-BhE-ZzRwVeA.html

No it doesn't.

No one knows besides some engineers at Tesla. I have seen no proof of anything working definitively.

False

It's not true. Otherwise everyone's range would tank in the winter

More rumors! 😂 I'll have to do battery calibration episode 2! Calibrating on a 120v would take like a week x_x

If you’ve been around since the beginning, and followed the TMC forums, you’d know about this already. ;)

@@SCWgreg I have not been around since the beginning that's for sure. I bet you $1 this will be fixed in a future software update :)

I should add, after your first 100% charge, you’ll never get that level of range again. But these steps will give you noticeable improvement in range, as your battery ages. Do another run down to 15% or 20% or so, then (if you can), let the car charge off 110v to 100%. I’ll bet you get 5 or more miles back.

@@SCWgreg are you just trolling me now? 😂 20% to 100% would take like 2 days...

When I do autopilot videos it makes it easier for people to see the small adjustments to the wheelade by autopilot.

Also he might of hard reset the car since he kept going in the back seat also??

Seems likely to get the homelink to work. I am not sure tho

Teslafi!

No, not in the main battery display. Only for routing. And it doesn't take temperature into account, just distance, speed, and elevation.

@@DirtyTesla Interesting, you think it would be effected by temp and display differently. The loss in range must be due to the baby and dog you store in the air intake. lol Btw did you hear amazon ordered 100,000 delivery Van's through Rivian?

@@travisg2224 I did hear about that. I am trying to interview someone at Rivian but I haven't heard back yet :(

@@DirtyTesla I'm sure they are swamped at the moment

Tesla doesn't want to use their data for it. It'll come to you eventually on LTE, but many weeks later than everyone else.

120v or 240v are still pretty slow compared to a supercharger, and should not do any extra battery damage. Tesla does say not to supercharger constantly, but some people do and have no problems with that. I'm general, fast charging is bad for the battery.

240 volt charging causes least degradation. A lot less than supercharging and a little less than 120 volt charging.

Any time. If I don't reply just keep trying, sometimes RU-vid doesn't give me notifications for comment replies.

You can try but i don't think it'll do much

I have 2019 3P Says 278 at 100% and 22,000 miles also. About 7% loss. Last year at 13,000 it was about 2.5% loss. I had Summon stand by on for long time without realising and it showed 10% loss. Turning that off returned about 3%.

I used to keep it on there so people could see autopilot's slight movements of the wheel in videos. I want to put something back.

Same here, AWD Model 3 17,300mi 90% currently 270mi (EPA) 6mi less than last month. I'm also hoping it's a software issue

I wouldn't worry about 3 or 4 miles dip, perfectly normal. Even my 10 mile dip idc.

Dirty Tesla yeah I’m not that worried about it. I just don’t want my 1-month old car to start dropping 3-5 miles a month. If it continues I’ll have to get it looked at. I’ve only got about 4700 miles on the car and it was purchased with 3 miles on it August 9th.

But the suggestion of calibration is still told to Model 3 owners.

That is not true. If it was, people would see their ranged reduced by 20%-50% in the winter and no one sees this. If they did, there'd be mass panic 😂

Your understanding is wrong.

It's a general rule charging is always worse for batteries. But there's plenty of evidence of people supercharging regularly with no more degradation than anyone else.

No but I am working on a battery video

@@DirtyTesla my MYP was 306 miles and now only 245 miles. Not sure if it’s a problem or needs a calibration? That’s a huge loss in less than a year

This video was from 2019. That little trick was added in a software update sometime in 2021.

the bms commnicates with the controller and ai ofc

probably the estimates range is lowered if you earlier driving is spend on many highway miles

Drew Douglas % is based off voltage of pack. Miles range is determined as an estimate based on your driving habits and pack voltage.

Wrong.

What software version are you on?

Just updated to 2019.32.2.1

Yeah, after I started driving at 100% my miles started going down like normal. I'd love to get even closer to 0 but it's so time consuming and bad for the battery... Are you on 2019.32 something as well? I think this software version is just killing the BMS

@@DirtyTesla I'm one of the lucky ones stuck on 28.3.1 even though I have FSD and update preference set to Advanced...

I made a video about the tire size here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-1FOcS6NpoAQ.html And electricity is fuel :)

Doinks! ...and I watched that video ... and commented! ...and you replied and I replied back. That video was uploaded on my birthday! Eh... I've never referred to electricity as fuel, simply because fuel is a gas. Electricity is energy, which is also what people get when we eat/drink ... certain things.

@@BrianJoslyn verb 1. supply or power (an industrial plant, vehicle, or machine) with fuel. "the plan includes a hydroelectric plant to fuel a paper factory"

That's a searched definition and is one that is faulty. Simply searching the definition of words is not as reliable as using dictionary.com. Search engines look at everything relevant to the search on the internet and with the magic of SEO (search engine optimization) it shows results. The first page of results, even just the first few results, are not always the most reliable. The first time I ever searched a definition, upon scrolling the first page of results is when I figured out searching definitions isn't reliable. When the power goes out we don't even use the word "fuel." Power outages, 'most commonly,' are not the fault of being out of fuel. It's the energy, the power, that has been lost. Yet, for those that have a gas powered generator, they would fuel whatever they need power supplied to. Thus, if it runs out of fuel (gas), this is when it can be said that the power is out 'secondarily' due to running out of fuel. Those that have a generator, but not gas powered, can't fuel what they need power to. It'd be pre-charged stored energy supplying the power. Hydroelectric plants may use fuel(s), but it doesn't mean if power is lost that it's due to running out of fuel. Consider... a Tesla could essentially stall due to something disconnecting, somehow. Or something could disconnect while it's off in which it just wouldn't power on. Just as with an ICE vehicle, it can stall due to losing energy/electricity somehow, even when there's still plenty of gas in the tank. Another factor is... fuels are visible, energy/electricity are not. Energy in people can be felt and noticed, but the energy itself still isn't seen. This is equivalent to seeing an EV being driven, whether via the energy of a human or via self driving. The vehicle obviously has the energy as it can be seen moving, but the energy itself is invisible. So, how is any of this validly wrong? Or... did I really just bust a definition of a word, according to where you got it from? I don't believe any of this is wrong. For as long as I can remember, this has been valid. Even when using the definitions I trust more, at... dictionary.com/browse/fuel?s=t I see quite easily how fuel is implied as something that can be seen. Thus, not including electricity. Even reading the definitions on dictionary.com for "electricity," including other definitions that are linked to other dictionary.com pages, all imply energy and not as being fuel. Such as "moving charge." Moving is equivalent to energy. dictionary.com/browse/electricity?s=t OH, moving charge... an implication of what is non-existent when the power goes out!

@@BrianJoslyn perhaps you are right... I'm still going to call it fuel 😂

Only for RWD, not AWD, and even then some RWD ppl got reverted to 310 miles

Dirty Tesla Hmmm. Didn’t know that. Was there any comms from Tesla on the recent reduction?

@@errodrigues nothing. No one is sure why or how they decided.

The main Tesla battery display doesn't change based on driving habits. That's on a different screen

@@DirtyTesla Oh, I see. I was not aware of it. Thanks! But still, could the anticipated range be somehow altered by the style and conditions of the drive (despite of what the manufacturer/manual says)? From chemistry side - batteries most of the time prefer slower charging over fast in order to get full capacity (hence the trickle charge in the end). Going this route - one could imply doing Level 1 or Level 2 capped at 10 A might restore full capacity. Also, temperature plays big role here. In FIAT I can read voltage of each individual cell. This can tell me how good/bad they are. At least to some extent... Could this be done with Tesla, too? The system is quite simple, on one hand, but on the other, there are so many assumptions and safety features involved that complicates the battery string charging characteristic. What applies to one cylindrical battery, may not really be same here... Yet, in the end I think it is simply algorithm in the software counting charges/discharges cycles and not allowing for more charge to be dumped. Hence less power delivered. And that is what I would actually compare. How much charge was DELIVERED based on % (that is 100 kWh battery - 70% should take 70 kWh, while charging more likely 75-80 kWh due to charging efficiency and lost power in heat and cooling pump).

Orange?! 😂 Nice! Autopilot does actually use a bit more battery, but only because it's more aggressive with braking and uses less regen.

Dirty Tesla 👍! Yes orange, it’s a nice Color! Lol! My favorite color is green and red
