This is true. The new structural battery packs aren’t financially viable to be repaired. To get to a cell means destroying most of the pack so it makes no sense vs older packs. However, with how strong each cell is now built and contained, with how much better the BMS systems are and with how much less parts there are (no more tiny little BMS wires like older packs) it’s also much more unlikely that the pack would need replacing in the vehicles life. Of course, this is yet to be seen fully. But this isn’t anything new. A replacement engine for my 2012 BMW X1 would be around £1,500 and after labour would be £2,000 or so. Which is cheaper than it would be to take the engine apart and rebuild it. I suspect by the time these cars/trucks are 11 years old like my car, a replacement pack if needed, would be around the same price. And they’re pretty easy to swap out too, not much labour involved

@Mladjasmilic Or, you could say that loss of one cell would be insignificant..... With 48(?) Cells per row, 7 rows per module and 4 modules, the vehicle has ±1,344 cells. . From recollection the Model Y pack had a welded cell connection plate that served as a fuse at the point it joined to each cell. . So, if a cell goes "high current" it would be disconnected. . If this happens, the vehicle (currently with a 125kWh pack?) Loses 125,000÷1344 = 93Wh of capacity. . That's ±0.74 *percent* loss per cell. ...... Congratulations on having the confidence (and ability?) to attempt repair of a high voltage pack. You must be one of the very few with the knowledge *and equipment* necessary to lift a car (safely) then drop a pack from under the vehicle (safely) diagnose the problem, strip it (safely), replace a cell (you mean module?) Balance, then reassemble the pack/ vehicle! . I wonder how much investment in lifting equipment (etc) and time that might take? . I'm sure that mere mortals would prefer to pay for 2-3 hours of professional attention to swap a pack which will be greatly reduced in price when the original is out of warranty in 8-10 years.... Maybe? Rather than days of labour to strip, repair and refit the original with no guarantee of success and probably no warranty on the work?

@MikkoRantalainen

@@TheConnor12500 If we assume that one cell has probability of 1 in million to fail, then a battery with 7104 cells (like in Tesla Model S P85) will work with probability of (999999/1000000)^7104 or about 0.993 or about 99 times out of 100. In practice, that tells us that 1 car out of 100 will have a failed battery pack if a single cell has failure rate 1 in million. Create a battery pack with more cells and you'll soon have a lot more failed battery packs. And I'm pretty sure that in real world a single cell has more than 1 in million probability to fail. Luckily, the cell manufacturer does some automated testing for each cell to try to remove the broken ones but this kind of filtering/testing can never catch all the failures.

Battery configuration: likely 192s 7p, which would be about 705V DC nominal. 4 modules of 336 cells each. The 4 modules are 48s 7p each. To be confirmed once they can look under the green foam which may hide a couple of more cells at the ends. There is a switching circuit that can either switch the pack to 192s 7p (all 4 modules in series) or 96s 14p (2s2p of the modules).

Their breathing and eye movements especially stand out, and they obviously fear correcting or disagreeing with the things he says. When Sandy is waxing poetic how everything they've seen so far in this teardown is wonderful and great and amazing you'd expect the engineers to nod their heads, add agreeable vocalizations, etc but instead they get shifty eyed, shuffle slightly, and remain quiet. When their turn to speak comes around they quickly start on a new topic.

Prior to the 4680 cell, individual modules could be replaced to fix in-service faults but the goop used in 4680 designs would would seem preclude any form of repair. I understand that Tesla themselves do not provide a pack repair service and expect owners to stump up for a whole refurb pack. Third-party pack repair is however possible but far less likely for 4680 packs. I hope the failure rate of 4680 packs is sufficiently low that this approach to manufacture will not prove problematic amongst Tesla owners.

Remember the flood ports and compressor are a necessity for fording water. The water is usually always cooler than the mechanical parts or battery pack. When the void is cooled it will create a vacuum and attempt to suck water in where ever it can. On a traditional banjo axle the breather on the top of the differential housing is a oneway valve to allow pressure out. When the housing is cooled in deep water the valve sucks shut. Water is pulled in past the wheel bearing oil seals . The larger the air void in the battery pack the more 'air' needs to be managed. The compressor is critical.

The air pressure addition would be useful if someone fords a stream with a hot battery pack, The cooling from the water in contact with the pack would lower the air pressure inside, possibly pulling water in through the vents.

You can have awesome efficiency and longevity if you work on all components and design them the right way, especially because all modern batteries are fairly efficient anyway if you hook them up to an 800V system architecture. As far as I know the Mercedes-Benz EQXX does jot have a structural battery, and the upcoming CLA class does not have it either. Yet the EQXX is the most efficient 4-door vehicle on the planet and the CLA will be the most efficient in its class out performing the Model 3. The point is, this argument is just vaporware. The most contribution to efficiency has the drivetrain and motor, the aerodynamics and the system volt architecture. The weight and the structural stiffness are secondary at best, especially because overall engineering has become very good. Tesla just uses the cheapest ways to produce components, and a structural battery plus a fixed chassis framework are easier to work on. This can have disadvantages, too. And especially for the end consumer the positiv effects might be minuscule. Tesla doesn't care about the environment nor does it care about the ownership experience and product lifecycle. They only care about their profit margins and that is not an achivement. BMW uses recycled materials and even creates or sources new types of materials for the interior and body panels of the "Neue Klasse. The steel they use is low carbon emissiom steel, the battery assembly will use renewable energies. And the battery pack as well as the whole car is designed to be easily recyclable. I am sure you can aslo repair them better than Teslas.

that looks very serviceable!

That huge battery jack was really cool. The electric scissor jack they have the battery on is cool too. 💪🏽

I saw a lot of people drawing hasty conclusions based off of the single photo Munto posted on Twitter a few days before this video went live, and I just want to say it doesn't seem like there is much room for another layer of batteries. Edit: its room for gas venting in event of runaway and also extra space in the event that you hit something underneath the car.

YEP. :d People are delusional. Why would u leave 80mm of extra empty space. Altought if they want too doo doubble pack they can in "theory" do it such way they decrease pasanger space and ground clearance if the mirror pack and compact it. Needed diferent central console and sets frames in this case. So 30-400 les passager space and 30-40 less ground clearence could give u dobble pack. But i m sure they will not doo that. CT in afterall niche product.

If this is the future of cars which it is. Then the government needs to take measures to get companies to providing funding for battery recycling like the recycling programs for glass bottles in the 60’s. I know there are programs that can recycle them but there will need to be funding for larger amount of facilities. These batteries are becoming more and more locked down and more impossible to work on individually.

Real engineers doing Gods work.

Wow! Amazing! I've been waiting for this for years. Thanks for the excellent job you guys do!

So to test for leaks all you have to do is sit the CT in enough water, activate "wade mode" and look for bubbles. Brilliant!

Another great video Sandy and Tom! I wonder if you could break off a chunk of thet structural foam and do a.Flamibility test? Tesla has some great solutions for handling water ingress. Unfortunately that foam is likely make the pack economicaly unrepairable, prevent fire fighter water application to the cells, and hamper efficient recycling. Then there's the stranded energy issue. In a.breached battery of conventional design dunking the pack remains in brine or sodium bicarbonate solution will eventually discharge all cell groups. With the pretty green foam keeping water out, all bets are off. At least my bets

More on the vent valves and their reliability in dusty environment, researling after contact with water and maybe some guidance on maintenance on these would be useful. In the nordic climate, the older model s are suffering from "leaky" valves where dirt accumulates and compromises the selaing, thus allowing more road dirt and winter road salt to penetrate the battery, even with no real water exposure.

How much energy and materials does it take to recycle and make a new pack? Thinking that this process is easy or green is disingenuous at best! I think GM and their Ultium battery system makes more sense.
