Repair Tesla battery for 1€ - 1 Cell Extraction
HTML-код
- Опубликовано: 10 фев 2024
- Model S with BMS_U018 is not our first visitior with same defect. One brick with fast self discharging requires fast respond, and we immediately starter battery pack measurements and decided to go with 1 cell extraction.
Cell successfully traced and extracted, and pack successfully restored to original working condition.
For purposes to troll diesel fans, we did this repair for 1 euro, no jokes.

Glad to see more people know how to fix those expensive packs. Great job !
This is truly amazing to see how sustainable this platform can be. Thank you for sharing and showing this to the world.
Inb4 Apple or Microsoft enter the market, and find ways to make batteries irreparable.
@@NeblogaiLT They already are IMO...🤔😳😏🇬🇧
Great job! With people like you, driving EVs will become even more sustainable - and affordable!
That is our primary goal.
glad to see ur not just doing the snipping of one cell unless snipped from every brick. CAC matching is important, nice job mentioning that.
Thank you. This is truly inspiring and a great counter to the tired old argument about how we are going to replace our batteries when they finally runnout.
Congratulation EV team!
Repairing a Model S battery on a single cell level is a great job for the future of this new technology!
Another awesome argument against all of those “whatabout the battery live?” discussions!
Let’s hope that your knowledge will be spread to some more workshops to reach all the customers with the need for your help ❤
Thank you. We have “mythbusting” mission
If it was up to me I would use a thermal camera to find the discharging cell because it would acting like a resistor and be getting warm
Amazing, I hope the company grows and expands
Very impressive, you are the most advanced EV repair shop in EU.
Congratulations and greetings from Bulgaria! This really makes EV transport even more sustainable! It may be harder to do the same with Model Y ans 3 packs as the cells are glued together, but I'm sure it would still be possible.
It is easier with M3, not harder, you have that video already.
@@evclinicexcelent work. What you think about Teslas 4680 which is glued that red polyurethan?
@@joonas9750 i think it is possible to repair that too.
So great to get your videos again - please keep them coming!!! (S85 RWD owner 🙂)
We will, we are really overloaded with repair requests
@@evclinic Your company and staff should grow +100% every year. Maybe a franchise system in Europe? "EV-Clinic Network" 🤔🙂
That is what I call sustainable! Even if you do not do it for free, such a service is wayyyyyyy better than exchanging whole packs or even the entire pack for 20000€ for absolutely no reason.🎉❤
12k+ labor with core from Tesla for remanufactured. About 10k without core and another 10k for a new pack with no core. So 12k€,22k€,32k€
I own Model X 90D
Still 1 year of warranty for battery but after that...
Nice to see an option of repairing that cheap.
Croatia has natural born talents for electric cars.
You guys
Rimac
❤️❤️❤️
Thanks for sharing
It is nice to see how clean and organized is the workshop
Impressive, I hope we have similar expert here in Ontario, CA so I can buy older Model S here
What arc pulse welder did you use?
In future we need a lot of such CLINICs. But there is a lack of experienced persons having such a knowledge. I guess it is also quite dangerous if you are not carefull at work.
Does amperage difference is applicable to all of the cells in all of the module ? Or is it module by module or section by section ?
Great job! Experts at work! Why not with the "Starwars Laser Gun" this time? 🤔
Greetings from Germany and thanks for the video!
Thermal camera will show heat generation. Charge the brick adn look
What is a welding machine type?
Is this an argon welding machine or not ?
This seems like a good and professional solution. But how do you counter the argument that Jason Hughes from the US makes, that it’s not possible to change a cell an even modules, because the battery will fail again within 1-2yrs. He is probably one of the most respected Tesla hackers and has huge amount of experience with Model S. I really wonder who to trust here.
I trust only real life experience and results. Our 1cell repairs are still driving and not failing. Statement that 1 cell defect and 1 cell change is not helpful is not correct
Jason Hughes also said Tesla tried module swapping for remanufactured packs but stopped doing it soon after... So I tend to agree with Jason. Maybe these fixes last 1-3 years, but not 8 like a Tesla remanufactured pack should.
@@rkan2 Not fully true, Jason is good IT guy but nothing close to our ex Rimac and Tesla battery engineers. Mixing cells with new one is not allowed, and test are neceseary to determine state healthy cells (dcir acir esr cac). Then you match used cell library stock with existing pack. Non of that is used by Jason nor has equipment for that. Jason is missinformin public about something he dont have skills nor knowledge to do. He is mythbusted. Cell level repair is possible with prober cell stock proper lab equipment.
@@evclinic That is exactlt what Tesla was trying to do 10 years ago but promptly stopped. How many Tesla batteries have you fixed? 057 Technology, LLC has according to Jason fixed quite a few and are the only company in the market now offering the extended warranty on Tesla packs provided wk057 monitoring is enabled.
@@evclinicExactly to the point👍👍👍
I thought that by buying an e-car I would have some peace of mind. Shrot mobilitet.
Great job as usual!
Thank you so much for this video. I am on my second S with failed pack (water...) and I wish you were closer
Ultimate Tesla killer is not Nio, Lucid or EQS. It is Water ingress
@@evclinic Also replaced 3 LDUs. Reman lasted 79k km. Any update on the one installed in yours?
@@VegarHenriksen My made 30000km, one from Hansjorg with 2million km Tesla i at 150,000km.
Our solution is bullet proof for LDU
@@evclinic Awesome. That is the LDU you made, right? How much is it roughly €?
I found on website. 3.875,00 € inc. VAT
Will definitely purchase next time mine fails. Thanks for the hard work!
Where you located ? Can you fix my 2014 Model S same issues? And how much will cost me ?
Thank you for the video
How do you force balance a tesla pack?
great work out there! curious what the toughest job, soldering? or pulling the cell out? looks like a lot of glue. either way not worth the risk which so high voltage
Module is 24V, that is not high voltage
Do you provide any type of warranty ( e.g. a large labour discount if it occurs again within 2 years or so ) ? What would be the price to check the battery and replace 1 cell ?
2 years warranty on full labor price. Unlimited mileage, SuC charging desired
@@evclinic Will contact you if needed , thanks for that swift response, I guess pricing is happening in private communication
wow great job .... but what is the cost for the costumor for one cell repair on one module on a model S .... my self have a p100D and when it dies i think i will drive to Croatia to get it fixed by you guys .... thx for the video :D
Bravo ekipa!
Doing something like this in the old days required lots of notes and metering on old Nicad aircraft batteries packs, couldn’t imagine that many cells you deal with, you definitely need a computer to keep track of that many batteries cells. At least you don’t have to worry about fluid levels.
Awesome! 👏🏼
Why is a pack only built from kind of 18650 cells and not from lifepo4 cells/packs like GBS? this pack has an amazing BMS in it. My opnion is this not necesary to balance 15 modules with each 6 cells
Bravo za sliku u reciklaži!😆
2 Issues.
1. I live in North Germany. Is it posible do deliver a EV to your Company and back?
2. How long does such a transport back and forth, including a repair, take time on average? How much does a repair cost on average at your company?
No issues:
evclinic.eu/2023/04/07/evc-sky-is-a-limit-international-delivery/
Transport depends on transport companies. 1-5 days usually. Average price we tend to keep between 4000-6000€.
Sometimes if it is something simple, like fuse cover, we charge 1000€.
I am surprised you removed the cell physically, I had expected you would leave it in place but simply disconnect the positive terminal of the problem cell from the rest of the block. In doing what I describe, the recovered overall battery would be around 1.3% lower in usable capacity but much better than the 30% reduction of usable charge when it was brought in.
Problem is more that 1.3% if you are taking it out from lowest CAC brick. We road testet 18 months several cars with 1 cell failure / repair and it is sustainable. But there are several rulles which you need to apply. First one: you cant put new cell….
Does the new cell not keep charging at different rates than the old cell and in a few months time the delta of the section will again be too large?
We dont put new cells, that is biggest mistake. We use same age healty cells from other packs wirh same dcir acir cac
@@evclinic I should've been more clear. I watched the video and saw it wasn't a new cell. It is however a new cell to the old pack, even if it is already from a uses pack. It shouldn't matter how old the cell is. What matters is that the new im whatever way aged cell will always have worn differently to the rest of the cells in the pack to be repaired. Thus it will drift again. Maybe this repair will be longer lasting than module swapping since it only affects a smaller amount of BMS'd cells and might stay under the thersholds. However I still doubt this will last 8 years.
I guess it also doesn't matter for most companies doing this since they don't offer the kind of warranties like Tesla or 057 Technology.
If you want to put your money where your mouth is, you should offer similiar warranties imo.
@@rkan2 We mentioned, that we recycle old cells.
@@evclinic Touché
Is BYD blade battery inside Model 3 (LFP version)?
Will that also be repairable?
That might be extremely complex to repair
@@evclinic Did you ever saw a CATL pack in real live or on video? Munro talked about "Tesla LFP" while showing another manufacturer. 🤷🏻♂️
@@evclinic ruclips.net/video/HPTefsqNGI4/видео.html
LFP have 10 times longer lifetime then Li-ion so don’t worry.
@@volkhen0 That must be confirmed first on road. NMC 18650 can make max 600k km, 2170 500k km. LFP what it seems from Tesla warranty returns is 300k km. Degradation is bit faster and small kWh packs die faster
I own a Model S 2015 with 94k km. Should i expect needing HV battery repair soon? Wondering if i just sell it
I have one with 380.000km and only 14% degradation. If yours has the LDU check for coolant leaks (rotor seal).
What's the cast to remove and put back battery Tesla 3 LR? Fixing battery pack Price from to? I'm asking because used battery is from 5000 euro 2019-2023.
Remove replace reinstall and collant flush 800€
great job, how much will a job like that cost? must take a lot of time?
Actualy 2-3 days needed.
We will make it affordable and sustainable, if 1 cell defect then 3000-4000€ price is planed, with full warranty. (With resealing)
Great
Super da netko ovo radi kod nas. Velika podrška.
How did you identify the exact cell to replace? You didn’t show how you extracted it either!
We have special equipment and set of tools which is our business secret and part of EVC Academy training.
The problem cells are not dead (disconnected from the pack), but rather they have a small internal short, which slowly drains that entire brick. You can use CAN data to find the brick (the brick who’s voltage is dropping), then since all that energy it being turned into heat inside that one cell, an accurate thermal imaging camera can see it. Or maybe they made a miniature clamp meter for the fuse wire. Lol
Another famous repair shop merely cuts the fuse wire, which allows the battery to work normally, but with 2% less capacity.
EV clinic goes a step further and replaces the bad cell to restore its capacity back to the expected capacity for its age.
Both processes are rather intensive, and almost the same amount of work.
Remember this is a bandaid to allow the entire battery to keep functioning until the next cell gets an internal short thats too weak to blow the fuse wire or CID. For a fraction of the cost of a new battery, you are back on the road.
Replacing the entire module would only be slightly better than cutting out or replacing one cell because the odds are the next cell to have this type of failure would be in once of the other modules.
Totally dead cells can also be found with thermal imaging by fast charging and discharging that module and find the cold cell. Normally they don’t do this because 1 dead cell is not a big deal. But one self-discharging cell that is still connected can be a major problem.
🤔 instead of replacing the cell. Can you just isolate it? Would that work..
It would work, but if that brick is with lowest CAC (Ah) then your pack will lose 3Ah of capacity. Which is equivalent of 4.8KM of range. It will increase strain on brick during charge and discharge by 1.35%, might decrease charge speed and will increase posibility of premature repeated failure. In most cases should hold above 2 years. It is easiest type of repair.
So many cells, so many opportunities for failure....🤔😳😏🇬🇧
And still it drives 600.000km
@@evclinic Maybe so, but I'm a retired Engineer.. I'd never have an EV because the battery packs are not designed for easy servicing...It's not complicated...😏
@@EnglishTurbines good you are retired, because battery packs are easy servicable if you have knowhow
@@evclinic Oh, kudos for fixing the pack...It's just that IMO, the dangers of dismantling the pack and fixing the dead cells require skills that are in short supply. The Labour costs won't be cheap but neither is the cost of replacing the entire pack...I'm sure pack fixing will become a thing. It's the failure rate and time to fix them which will be the issue IMO....Have a nice day....🤔😏😏
will tesla accept a repaired old battery pack when I like to get new battery from them ?
Only if BMS has original data, Serial number tied to that VIN
@@evclinic Thank you very much !! So Tesla will take the battery back as deposit, even when if it has been opened by you and the data is correct ?
I'm excited
Let's see when we meet. I have a Model X 2016 with 250 000km on it. Still good but, who knows how long?
Greetings from Sweden.
Should hold 400k
Keep up the good work! ❤
Nice job! That seems very impressive what you have done! I have a own carworkshop in Germany and started to treat electric cars since 2019. So far I didn’t have a single defect highvoltage-batterypack. But in the future I plan to do that as well. It’s „simple, cheap and environment friendly“.
Hope you can keep you profession and improve your knowledge!
Greatings from Germany
Thank you for your support
In my opinion, this is where prismatic cells are better, easier to replace (correct me if im wrong).
Not exactly true, much more problematic to change because they are pressured between all other cells. You need to cut frame dizsaseble everythjng and change. All of them are glued too. We had experience with VAG prismatic and it is almost impossible to change one in a cost effective approach
Jel radite na Hyundai Konama?
Sto treba
@@evclinic trenutno ništa, ali sam upravo u procesu kupovine Hyundai Kone EV, a radim godišnje 50000km, pa pretpostavljam da će eventualno trebat baterija balansiranje ili popravak kroz koju godinu.
I changed 69 cells in one block of a 2008 Tesla roadster, a month later the car stopped again. (Next brick, next cel)))))
Roadster is nightmare, cell quality and troubleshooting, if you test cells properly, i mean realy precise you could detect potentially bad ones. Time consuming, and roadster btw is outdated and killing cells by bad charge voltage range.
Tesla Roadster has crap cells and not worth trying to rescue old packs. You have to exchange ALL cells. Otherwise it is a stupid work.
@@evclinicyes. I am fix 4 month)))
@@evclinicGuy in Denmark is working on his own custom battery pack for the roadster, based on Model S modules

This exclusive tool is SimpBMS 😅 , wow, You are genius, bro. Why You dont show all truth, its 3d printed cover from Yours shop:)
Why you dont tell the truth, it is modifed Jason and EVTv code :) we modifed and produced our simpbms, pcb and code to fit our needs, so actualy it is not simpbms.
@@evclinic You show on laptop data and that's the same like in my simpbms. 👍 for repair of old Tesla battery. I have that modules and simp on my home made powerwall.
@@michachojnowski9004 Printout is same, i am not reinventing wheel there.
The first: You can’t compare a pack to 3x expensive pack.
Second: Leaf has most repaireple pack and they do it by dealers carage so there is no need for special arrangement.
And it’s also the cheapest one to repair by dealer or replace, whatever Teslaquys tried to tell to you.
You can show me also how to repair or rebuild last genereation Teslapacs. Yes, with that messy spray insulation means no repair at all. One bad cell and to the crusher. Tesla has the complicated batterypacks for thrue.
I am a batterypack builder, from scratch also, so i know what i’m saying and you simply use thermal camera to hunt those bad cells. Leaf pack technician needs to use only phone aplication to find a bad cell.
Leaf is the worst pack ever produced, most degraded and big safety issue because cells inflate. OEM repairs them by mixing cells and it cant hold for any reasonable period of time. In UsA they recall them. Second, leaf battery is 2-3x more expensive then tesla pack in OEM

Spare part 1$/€ worktime 5000 $/€
This one was sponsored by hybrids, worktime 0$
that fix will only last months if not less. get a new pack, lol.
Not true. That is Myth sold by incompetent “experts”.
1 cell extraction road tested and still driving, with proper measurements of old and exchange same cells with same internal resistance and CAC repair works perfectly.
most used word ehhhhhh 😂 otherwise good info
This is not for you to decide what diy can or cannot do! If you don’t show it then there’s no value in your video!
You dont say how to find the defect cell. You dont say how to change the cell. Yout dont say how old the car is and dont say how much km it has. Not very much Informations from this Video.
For any advanced technician there is enough breadcrumbs to replicate it. Everything else is our business secret. Topic was cell extraction, not bicycle production or car reselling. If there is not much information for you please unfollow. In short video i mentioned it is 2013 P85 with 260000km
so every 2 years your car will be off the road to get defective batteries replaced...and who is going to pay for that...TESLA? Insurance (good luck with that one) or the customer?
How many days does it take you to remove and find the faulty batteries, replace them and refit??
seriously, who is going to accept that as a viable proposition??
We need 2 days, still no cars returned with 1cell extraction.
The filling of the chemistry cells is made of the same material. It seems to me that this is a stupid job, since the next week or month you need to change more cells.
It seems to me you have no experience with lithium cells and your comment is incompetent and incorrect.
Not stupid job, we have 10 cars already driving. It is stupid to change one if you dont have equipment to test all of them.
Nije poenta u tome koliko košta popravka, nego da je taj auto nepouzdan.
Drugo, bez obzira što je popravka jeftina za servisera, za vlasnika automobila će biti skupo, mnogo skupo...
Ista je oriča sa LED televizorima. Zamena jedne LED će definitivno dati rezultat ali to ne znači da se polovnim delovima može servisirati i očekivati da služi svrsi. Moraju se zameniti sve LED trake, naravno, mora se ugraditi nov deo ili novi delovi.
Isto važi za Teslu. Ovo nije popravka i neće trajati.
Nije poanta da je tvoje misljenje bitno i osvrt nepouzdan, vec da je vec par vozila reparirano sa 1-cell swap i voze taxi, samo jedan u privatne svrhe. Vec preko godinu dana. Ta vlasnika je iva popravka sa videa vila 1€, ruke je platio vlasnik Passata CC sa kvarom DSG mjenjaca.
