- čas přidán 21. 10. 2020
- We decided to venture into the Model S battery world this week and took apart a customers vehicle to isolate the bad sheet and cell. All it took was one single cell out 7000+ to completely shut down the main propulsion battery pack.
In this 2 part series, we show you our process for taking apart the battery and repairing it’s underlying issues.
Stay tuned for part 2, and thank you so much for supporting our channel!

Right To Repair is a movement everyone should get behind so that we as consumers and also private business repair shops of all kinds can have the ability to repair these products without being forced to only go through the original manufacturer for repairs. Bring back the old days when we all had access to parts, schematics, manuals, etc. To do the work ourselves.
@sparkie996 We now have access to the "tool box" and service screen, so that's great. We just need access to order all parts.
Anyone who claims to care about the environment should be actively supporting right to repair.
Musk added apink slime to the new batteries so you cant replace (right t repair) modules yourself. It's why I wont ever buy a Tesla . Replacement Modules for my ID 4 are $500-$800 cheap and I can have my loclal mechanic swap them out for me
CRAZY DESIGN.
1 bad $3 cell disables a whole car, a whole battery pack, for such a massive dismantling, diagnostics, then "we just snip it out of circuit".
CRAZY DESIGN.
the F150 with the Ecoboost it easier to remove the engine or more commonly remove the cab to do engine work.
Agree, we should have software in the car where it would show the bad cell. It should be easy to drop the battery with a few bolts, open it up and replace the battery. Wonder if you get a warranty with Gruber motors after they replace it!
I love how you explain things. Very clear and informative.
I was going to post the exact same thing, this guy should a teacher!
@@marcroy8023 Great minds...
So true. Not an actor, no dramatization, just a guy who knows exactly what he is talking about and edited down to the density of a Hemingway short story.
The problems is, there are not many shops who can repair these batteries. They are increasing, but they are still few and far between. If you are in some place like Montana, you may have to be towed a thousand miles!
And, somewhere between 150k and 200k miles, you are gong to have to get the battery pack fixed.
@@roadscholar05 If somebody in Montana buys a Tesla they are asking for trouble.
Glad to see Mike Ehrmantraut has found honest work in renewables.
Awesome, nice to know that there are options for older Tesla vehicles besides purchasing a new battery pack.
Of course there are. Not just for tesla. Imagine this car is an overgrown cordless impact driver.
If only car manufacturers would make the battery pack maintenance and inspection easy and accesible, not requiring extensive and expensive equipment to access. The right to repair, not to be abused by dealers that will push you onto new battery packs because the old one is old and dead, when in fact a single cell replacement makes it great again, even after maaaaaany years of use. But that is the scsm of the official dealership, a monopoly to prevent customers from fair repair.
@@tommyb6611 ...exactly my thoughts too. It's still expensive to repair, similar to an engine rebuild on ICE vehicles.
@@AudiTTQuattro2003 It’s nothing like an engine rebuild? You disconnect the HV, drop the battery out and remove the lid and a couple of hose fittings. You can check the battery voltage with a $20 multimeter. Yes it’s a sealed lid and removing and resealing it isn’t easy and that’s the part where specialist tools come in but that’s because it’s a completely sealed system - on purpose. That’s hardly engine rebuild territory. To put it into perspective, Neo (Chinese EV maker) just completed it’s 2 millionth battery swap. It takes about the same amount of time as filling your car with gas. Even Tesla’s battery is pretty modular.
@@christinalaw3375 how is that unlike any car maker with non EV cars?
@@AudiTTQuattro2003 you have no idea, you pull out a 10 year old battery pack to replace dead cell, put it back together and in a few weeks weeks or months another cell dies and need to do it all over again? That’s why Tesla want to replace the whole battery pack, and when you rebuild an ice engine it’s good for another 10-20 years
Amazing that one bad $2 battery cell can be the demise of a $130,000 supercar. Cheers to you for your sleuthing skills and sharing the inner workings and solution with us. As we transition more into a BEV society, these repairs will happen more often. I imagine a more serviceable product will be mandated. Thanks!!
Just like a $0.01 resistor being the demise of a $1200 phone, $1600 video card, or $3000 laptop. Electronics are just expensive things made of thousands of very very cheap things.
That electric jack you have to remove/move the Battery pack is way better than what they give us at Tesla to remove/move them. What we use essentially a padded table with 4 coaster wheels we have to push around and its at a Set height lol.
This is an excellent video which goes to show that whilst your Tesla battery MAY get a problem, it's not usually totally dead and buried.
Thank you for sharing this! My 2014 P85D has two years of battery warranty left and given the track record with drive unit replacements (3 so far) it’s comforting to know that there will be a non-Tesla option when the time comes for work on the main battery pack. I asked the Tempe service center last time I was there what the cost to replace the pack would be (since they do not repair, only replace) and they said “about $25K”. And that includes the credit for trading in the old pack! Very glad to have you guys as a local alternative to the Tesla service center - you’ve already saved me a ton of money on air suspension and other maintenance items. I think you’re going to get VERY busy as the 2012, 2013, 2014 cars begin to come off their powertrain warranties!
We plan on expanding to meet the needs of our customers. Thank you for your business.

@@petegruber2353 Would be curious what options are for east coast cars-- since cross-country shipping is $$. Maybe partner with Electrified Garage? They need more locations too though. No viable options in my area that I'm aware of.
@@petegruber2353 Please open a location on the East Coast around DC or NY :)
It's a steal consider fe battery price today at about 100$ per kw
You can sell a pack with one failed module for like $8000 (they are bought for DIY powerwall and gasoline to electric conversion purposes). What's the cost for Tesla to install a new pack into a car that has had its pack removed and sold already? It could be more cost effective, ending up with a new pack and all.
4:43 - to clarify, 4.2 volts is a normal 100% charge voltage for lithium ion batteries, and the 3.6 volts he speaks of is the NOMINAL or average voltage, not at 100% charge. Same battery different charge levels.
Could be different battery chemistries. LiFePO4 charges to 3.65 max, 3.2 nominal.
@@MortimerSnerve no model S uses lifepo batteries. Only standard range in china model 3 does atm. Also I think those in teslas are the higher capacity panasonic ones that are 4.3v for 100%, but never charged to that for better life cycles.
@@gelisob Well in reality, any Nickel based Lithium Ion cell can be charged to 4.3V. It's just always a compromise as each voltage increase of 100mV beyond 3.9V decrease cycle life by a factor of 2.
Probably different batteries
I work and fix tesla batteries in my country for 2 years now. The battery is super sensitive and you must take care of every step you make. One of the most hard things are sealing the battery pack so it will return sealed as it was, the problem is that it will not be water resistant as it was before, which means you cant drive it in winter again. For now the best sealing way is using rubberized silicone and a nylon cover. This prevents water from getting in by approximately 70%.
I like tô learn more about batterys on Electric cars
Where can I find online courses
There are 3M sealants that are 100% waterproof used on boats and in salt water (3M 5200). So if you are getting water into your batter casing you're doing it wrong. Either you're not using the correct sealant, or you're not applying it correctly.
@@jrmorrissey207 Honestly this is the first time I've heard of this sealant, I did some research about it and it seems like it is the best sealant on the market. I am ordering couple of them soon. Thanks for the advice though.
You must use 100% polyurethane-based caulk only lasts 25% as long as pure silicone does?
Great video; you should be a university professor. You explain things clearly using simple and plain language that anyone can understand. 👍👍👍
I didn't know John Locke
from "Lost" is repairing Tesla battery packs....pretty cool.
I was going to go Paul Shaffer, but I see what you are saying
You guys are great, as a tesla model 3 owner i am so glad to see you out there doing this work and offering options for people i wish you all the best!
I am so happy your around the corner with my latest acquisition. 😁
Welcome to the world of sustainable energy and Tesla Paul.
Pete
yeah welcome to the wonderful world of expensive repairs and high depreciation!
Thank you for sharing. I watched the electrified garage fix a battery pack and their system identified the bad sheets and bad cells within those sheets while the battery was still in the car so they knew where to go before they dropped the battery pack.
So one cell here and there doesn't affect overall battery life that's truly a stellar example of redundancy
Elegant, simple but very crisp explanation of the problem and solution.
Yes, someone that can explain clearly and precise on battery cell packs!
What an incredibly informative video.. made it understandable for folks like myself that have 0 clue what the future looks like.
You are so far ahead of the curve! Glad I found your channel today. I look forward to watching more of your content to learn all about Tesla EVs from the inside out.
Gruver I know you were a university professor, great presentation and explanation sir.
Knowing the ledge is very good and sharing is good also we all cannot do everything but having some idea about how things work is very good also
Great explanation, and no political ads!
LOL
Love how he explains this fix video. Talk about someone who isn't full of himself but really wants you to grasp the way Tesla's perform and function. Excellent video!!!
PS) I had no idea that those (VapeCigBatteries) 18650's were in parallel. That was all that's in a dang Tesla. I know that's the same with Renogy Solar Batteries too!!!
I need to know where we can find those replacement sheets (a single battery sheet)?
Ha, reminds me of going through the old Christmas tree lights trying to find the bad bulb. Interesting video.
What a great simple explanation of how it works and how you repair them.
Awesome!
Nice work keeping the battery cover flat for reuse.
Oh it’s like those annoying Christmas lights that if one goes out they all go out. So smart and green. 😂
You are the future of mechanics
Thank you - czcams.com/video/QRS6_fpyFig/video.html
Solid work from the people at Gruber Motors!
Just what I was looking for on my scavenger hunt today. What great Fortune.
Your videos and company is needed ..thank you much.. from watch your videos.. I actually feel better about owning mine
Great service, the model S is alive again.
Besides tech, you're an excellent teacher :)
1:26: "It requires special equipment to remove": Hold my Rich Rebuilds
It's engineered to be removed in 2 minutes.
A lot simpler than an engine repair on an ICE car.
@@graciescottsdale perhaps one day, defo not yet.
@@brad9529 There are videos.
Huh, this channel is actually kinda cool! Found it through some random internet blog/news website and for once it actually led me to something cool!
Much more content is coming.
The sun is shining in the shop.
And in some peoples finance after receiving this type of help
Great and very interesting talk, I just got my brain oppened up to how the battery system workson Tesla.
Great video, explained very well. You are a great teacher in that regard.
Very clear and informative tutorial - thanks !
Very easy to understand even I am not a native speaker. Amazing!!
Really great to see what you do, giving a new lease of life to battery packs.
love the channel, so happy youre giving these great cars new life.
Excellent video and explaining of the battery. Thank you very much!
This is awesome! Would love to see the replacement happen too - as well as the "power up" and drive.
We are working on the sequel. It supercharged this morning.
Here you go:

@@petegruber2353 This video and the one linked dont show you repairing a damn thing. take the fucking cell apart and do the actual repair.
i absolutely love this company reviving Tesla to improve them.
Great info will surely need one of these days.
Really grateful
I love this sort of jobs, great stuff.
Great video, couldn't have explained it any better!
Nicely presented with details and no bullshit. I like such informational videos. Don’t own Tesla yet but following closely for future ownership. Thanks
Well spoken , learned lots. Thanks
I've worked on electric buses which uses software that looks at each cell within a battery pack - voltage and temperature - therefore can tell exactly which cell or cells are defective. I'm not a software engineer so I have absolutely no idea what's involved there. All I know is, whenever there was a problem, I could plug in my laptop into a specific network port to look at each battery pack, then zero in on all or individual cell in the defective pack. That made my job really easy.
Beautiful, great job.
I always wondered what Gruber electric Co. did and it never occurred to me that you always had a Tesla or three in the driveway!
Stumbled across this excellent video by a feed in Google. I immediately subscribed. The photo is of me and Betty, your neighbors.
Thank you for providing this service. I will be shipping my 90d to you soon.
That was amazing.
His future is so bright.
The special process to determine the bad cell is most likely a thermal camera. When you charge the pack and watch it's temperature, the resistive cells will get hot and show quite clearly on a thermal image.
Snipping them out is fine, as long as its not too many per pack. Effectively removing it will decrease the whole packs capacity, which will lead to balancing issues if a lot of cells are removed in this way. So if this is done repeatedly to a pack over a few years there will eventually come a point where you need to actually open it up and replace the faulty cells with new ones.
As far as I can see the cooling solution they've gone for is flat tube sandwiched with thermal pads in between the cells. That way the cells are not directly touched by the coolant but can still dissapate their heat. So a replacement of cells should be possible, although it will take significantly longer than just cutting the fuse. So its best to only do this if the pack has lots (Say more than 10%) of bad cells.
Thermal camera might catch it, or you could probably use a sensitive DMM to measure the voltage drop across the fusible link to each battery. At equilibrium the bad cell will have approximately 74 times the voltage drop seen on the good cells.
@@fredhamilton1701that would be fine if the cells where in series but there in groups that are parallel. Put it on a power supply and wait for the hot spot, simplistic/fast. The real problem, it is all a waste of peoples money to do this. If a pack could be r&r in a hour that would be fine. The labor time to do this makes this a loser. You could fix it and two months later be back in it. The cells are going bad across the board because of the number of charge/discharge cycles. Great money maker for the shop, suckers bet for the customer.
@@mitchellcrane9809 The cell became resistive and perhaps that can be caused from the cycling, but it can also be a defective cell and not an indication that many more are about to fail. I've built 2 EVs with LiFePO4 cells whereas the most recent one has 38 cell modules with 52 cells per module. After just one year of use, I had one bad cell out of 1976 that went resistive. I designed my own BMS and was able to compensate by adjusting balancing parameters for that module but eventually, I added a one-off cell balancer to keep that cell topped off. That's worked for 6 years so far but I really should pull the pack and replace that cell.
Only a sucker would buy an electric car
@@NP-co7kj
What do you mean by "topped off"? You bypass that cell? Also, if you replace that bad cell, will it throw off the balance because of age/capacity differences? I'm trying to learn about battery management.
Very good information especially how you explain it in very simple terms
Very informative and simple explanation
What a great explaining ! Thank you
As a former electrical service & design engineer, I can tell the battery monitoring and services are most complex tasks in substation services.
Brilliant, well done.
Very nice guy, great video, appreciate the time and effort!
impressive ,thank you for the video
Excellent video. Good speech rate and very informative.
Great video thank you
And I thought I was a kid genius when changing a bulb on Christmas lights
Superb video! Lots of tech stuff which is tough but nicely explained
The best and most informative Tesla Battery 🔋 Pack video I’ve seen
Andre Young We appreciate it! Part 2 of this series will be released shortly.
@@grubermotorcompany On a salvage car(missing battery) there`s no reason someone cant build a battery pack using other battery formats with the right software/bms to talk to the OEM Tesla software, same goes for after market chargers, motors from Volvo/VW/Porsche etc would be a perfect engineering project in collage/uni etc....nothing wrong with learning :):)
THANKS4GIVING a great post
Very well explained.
Great Video- thanks Mr. G
Very cool vid, glad to have found you guys.
Great video. Thank you.
I had heard something to the effect a long time ago that these cars were powered by a shitload of 18650 batteries, but I never followed up on it. Nice to know that what I heard several years ago was true and accurate information.
You guys are giving away the farm. I appreciate it though. Very informative.
Very well done! You guys are my company when my battery dies
Very interesting and informative, thank you. It's exciting to watch a company such as yours enter into what I would call "uncharted waters", apparently not to you, so good work and keep it up!
As always, great work by Pete Gruber and the Gruber Motors Team. Please open a shop on the East Coast.
Like in Maryland!
Thank you. Scaling what we do is in the plans.
Dont forget the East coast of Australia
Very nicely explained

Thank you! We work hard on these videos and feedback like this is very uplifting. Hope your weekend is a relaxing one!
@@grubermotorcompany if the only other option is a $US25,000 ($AU33,000) repair it would be economically feasible to fly you out to Australia to do the repair.
Hello Mr., you´re a awesome. Thanks for sharing your knowledge. Regards from Brazil.
I'm glad the newer designs they are using today in the Model 3/Y and new Model S don't have this issue. These old Model S's are when Tesla was still struggling as a company, they've come a long way. But it's good there is an independent repair option.
Curious how the newer designs overcome this ? Is this indeed true ? Also curious how long it takes to find the module and then the particular brick and finally the "rogue" cell ?
I need this right now
Amazing, I have confidence I could easily do this myself. I'm pretty good with this stuff.
Still alive, bro?
@@hieroglyph321 yes, but lost my right arm
Thats amazing great video.
Great 👍 very knowledgeable.
