You are an excellent teacher. I really like the barebones man and his camera approach- no fancy graphics or video magic. It’s believable and genuine. The Matrix shades are a nice touch. MC Hammer would be proud of those pants.
Actually, 18650s are still connected in a lot of applications by nickel(not stanless!) Strips. But how they figure to use wire bonding for battery connection wаs been an awesome idea.
Another great Tesla video letting us know the engineering and tech inside. You have done amazing things to fix and repair these amazing vehicles. The battery pack was designed by ACPropulsion in San Dimas Califorina.
It is clear that this pack as well as most Tesla pack have not been made to be serviced. Do you guys at Gruber motor plan to design a replacement battery sheet design to save all these VERY epic T-roadster ?
There are loads of these around with dead batteries now. You cant get replacements. Not even lasted 2 decades. With the Elise you can still buy brand new engines from Lotus' stock. But you cannot store batteries long term, they need to be used or they will discharge and brick. In the UK there was a company selling new batteries (aftermarket) for them for a while. It burned down in a giant battery fire..
I'd be curious to learn more on the BMB microprocessor board on each sheet. And then understanding how replacing a sheet effects the rest of the system, can the PEM read a new sheet and how does it affect the sensors inside the ESS. This video is very enlightening though, thanks for creating it.
Hi Pete, could you guys do a video on swapping a motor? / upgrading to performance motor? ie: Model S 100D -> Model S P100D. Could you show us how it's done? I really would like an upgrade like this. Thank you!
EXCELLENT very clear ans comprehensive explanations! I myself make video about lithium ion DIY and i am inspired by the rate and easiness of explanation you have. thanks you for offering us sime sneak peak of these epic battery pack
Do you have any issues with Tesla making things harder than they should to repair? Suppling parts etc? Louis Rossman (Right to Repair) advocate might be interested in your thoughts.
Tesla does not intentionally make their product hard to repair. They would be shooting themselves in the foot since their Service Centers do the same work. They struggled with supplying parts, primarily high voltage parts due to safety and liability issues. 400 VDC components require special handling, tools, and equally importantly - experience. Not negating the fact there are unscrupulous manufacturers out there, more so in the mature markets like critical power equipment, that intentionally attempt to lock out competition with padlock software, or force service through dealers only, Tesla's parts, and service sharing policies do not seem to be motivated by these same competition control tactics.
Could a duff battery not be link bypassed to repair the pack, as one bad battery ruins the whole pack? Maybe break the connections of the bad cell, whilst plates still on, and wire in an external single cell to replace it but sited outside the pack. An infrared heat gun should be able to detect duff cell(s) whilst pack is under heavy charge or discharge (ie it will be hotter or colder than the rest). That way the plates with the fusible links will not need to be destroyed as you would not need to remove them?
A great video. I have a question about aluminum cooling jackets. Can hard pounding in path holes and vibration damage the aluminum jacket isolation causing a short circuit between aluminum jacket and cylindrical cells? They are in contact of each other to transfer the heat. Have you heard of any kinda short circuits and fire because of that. Is it really safe?
MAybe with a CAD design of the frekin' pack at the position of cell on a lathe.Try ro use some sort of drill to start drill battery itself from the pack untill you can replace with new one.It just seem impossible but i think it isn't in some circumstances.
The main issue is to find the exact cell which is bad, without disconnecting all of the others. you have to disconnect them, individually test them, then cut the retainer with a hole saw type device on both sides of the bad cell, then press it out.
Cool. Has anyone replaced these battery packs with something more modern? eg., packs from a Model S or 3? What's the availability of these battery packs? Can you get new replacements from Tesla? Or are these roadsters dead when the supply of this type of battery pack runs out? The reason for asking is there was a Roadster for sale in the UK (where I am) with a dead battery pack. Is it scrap or is it repairable - and if so for long?
There are much better battery cells available now. The limitation in the Roadster is firmware and electronics out of production and 13 years old. Re-doing these items for 2000 or so cars, is cost prohibitive.
Any opinion on 18650 Model S or 2710 Model 3 cell replacements on modules by drilling old cell off and glueing new cell inside the module? In europe there is a reputable company that has advertised doing this on multiple battery modules.
Since the Tesla Model S battery pack has the same number of cells as a Roadster, could a Model S battery pack (and its ancillary equipment) replace the battery pack of the Tesla Roadster? A Model S battery pack, and its ancillary parts, could be adopted to a Tesla Roadster, couldn't it? This would be an even hotter Roadster!
Looks like from tested 2nd hand modules. I know of a case in Germany (Model S) who's battery pack was replaced because of a faulty DC contactor inside. The replacement battery had less capacity than the old one and by memory the guy lost 40km of range (and was not that happy).
@@pashko90 I believe Service Centers never open a battery pack. Same with Drive Units: They always exchange the whole assembly instead of swapping out a worn bearing for example.
@@pashko90 I suspect Tesla keeps it this way to make sure the expertise how to fix things on component level stays with as few people as possible. Right to Repair issue. Nissan battery packs in hot climates......I rest my case.
There was a video answering this specific question up here a few days ago but I currently can’t find it. Could have been taken down because it had some weird kW vs. kWh mistakes in it. The gist of the video is the 100kWh pack is heavier and is not supposed to be used in cars not made for it. Upgrades to the 90kWh pack are possible though (probably unreasonably expensive though).
This guy is the Bob Ross of Tesla repair and knowledge.
Happy little trees,
Taking in the breeze, made green.
By Tesla's EVs

This man is both an excellent speaker and teacher.
I normally have a hard time keeping up.
It is clearly stuff that Sandy Munro would appreciate
Interesting history of the Roadster.
And don't forget to tip those cashiers boys and girls.. Oh wait, wrong channel!
It would be great to watch you do a dissection of the Roadster motor and transmission.
Great video like always!

Wonderful channel. Thank you for sharing your experience 😊.
Model 3 long range battery disassemble and explanation. Love your videos!
Very eloquent and knowledgeable man with outstanding business proves. Congs!

We are working on it with Tesla.
Hopefully sometime down the road you could develop a superior model 3/y pack replacement

Hi Peter I was wondering if you would talk about the chemistry on the old versus new batteries
Hi Pete, could you guys do a video on swapping a motor? / upgrading to performance motor?
ie: Model S 100D -> Model S P100D.
Could you show us how it's done? I really would like an upgrade like this.
Thank you!
I’ll talk with our video production team!
Or a 75d to 100 d performance would be awesome too!
Front of modes S AWD and RWD are diffenent(different frame rails, different subframes, and a lot of other parts).
With the right machine and tools I'd De sure that battery can be recreated
Love the information and the channel but I have never seen so many vehicles in one shop!
EXCELLENT very clear ans comprehensive explanations! I myself make video about lithium ion DIY and i am inspired by the rate and easiness of explanation you have. thanks you for offering us sime sneak peak of these epic battery pack
Nice explaination. Wish that you could start some online tutorials for Ev battries.that will help us a lot people like me..
Do you de-energise the batteries? How do you do it? Any safety tips on how to safely open up these modules?

Great video, thanks! Just wondering if there's any potential to create a replacement battery pack out of 2170 or other cells?

I would be very interested in learning about the mechanics behind the steering and braking of EVs VS ICE vehicles.

Panasonic most likely

They are possible to build from scratches if nessessary.

This guy is so bright he has to wear shades 😂
Can you show how to identify the bad cell in a block of parallel cells?
No
@@grubermotorcompany Ha
Nice video! So in the end, for the roadsters, do you replace each black pack?
Yes, you replacing modules itselfs.
We actually have perfected a repair method, down to cell level

What do they do if a battery pack goes out?

A Model S battery pack, and its ancillary parts, could be adopted to a Tesla Roadster, couldn't it? This would be an even hotter Roadster!
What will happen the damaged battery sheets please?
They taken for parts, you can recover remaining 18650s as other folks doing with S/X and 3/Y packs.
Nothing a 9 inch grinder couldn’t fix !
So what does a refurb battery pack consist of ?

@@moestrei Lol. As far i know, Nissan can repair his own packs/ EV components. Too bad for tesla :( thanks god, i'm fixing all of my stuff myself.

Im expecting this video from you❤
How will EV batteries - and especially Model S ones ! - tolerate the car being driven through deepish water?
The packs are pretty well sealed, up to a point. Length of time under water is of course a main consideration.

Y when you remove a bad cell y'all don't fuse in a new one
fucking gambling with this massive ncr cells (explosive cells) really dangerous game ...
