Just noticed a new Youtube video from a company named EV Clinic who have been repairing failed battery packs in Tesla Model S and also the Model 3. What is astounding is they are able to extract an individual faulty cell and replace it saving the cost of a full pack and/or module replacement. Much of their process looks to be unclear from the video but they seem able to extract single cells which I have never seen before. I spotted that some of the repairs cost from 3-4,000 Euro which is much cheaper than a full Tesla replacement pack. If someone could add a link to the Youtube video that would be great…

Looking at the Youtube video the repaired packs could be Supercharged. There is some debate about the longevity of the cell replacements and the repaired pack in general, noted within the comments section of the video, but I think EV Clinic will be offering a two year warranty. I think the Company is based in Europe. It is interesting that it is now possible to replace individual cells which might give us a route to cheaper repairs in the future. If this type of repair could be done in the UK in the future then I might consider keeping my Model S.

I've seen a couple of teardown videos of Tesla packs. The Model S pack was bolted and screwed together, but the Model 3 pack is glued shut, and there was also some kind of plastic membrane between the cover and the pack proper which could only be removed by destroying it. The people doing the teardown concluded that it would be almost impossible to properly reassemble the pack, it certainly looked far from straightforward.
Further to that, isn't the inter-cell wiring on the Model 3 some kind of vacuum-braized affair which is impossible to do properly without OEM equipment?

I'm sure it's possible to repair a pack so that it's good for a runabout in some far flung corner of the world (a bit like the beat up old Mercedes you see all over Africa). But I'm not convinced I'd feel confident to have a third party repaired pack under my Model 3 when I rely upon it for doing 1,000 miles a week.
