Munro has competition, this makes things more interesting.

This guy he is so well spoken and it's such a pleasure to hear him explain it all

That “range extender” port is actually where the other motor would plug in if you had a tri-motor cybertruck.

Crazy. Had no idea John Travolta knew so much about CT!!! 😂

It doesn’t take a half hour to pressurize the battery pack. there’s a half hour limit on the wade mode

Where did you get the 30 minutes to enter wade mode from? I see less than 10 minutes time from all other sources.

Wow, Thanks for sharing Terry! Some great work taking it apart so cleanly and really showing visually how this battery was engineered.

"We treat it as if it is full." Then John touches both contactors with his bare hands. I am sure they made it as safe as possible, but don't be a John and assume it is safe.

Good point regarding the rigid high voltage bridge being automated as a result.

To me the wade mode is most important in flood situations or when offroading and hitting a wet area.

This is an amazing job John!!! Our friend there was very kind to disclose everything for free for everyone to see. Amazing Job!!!

Glad to have found this so I have an alternative to watching Munro and associates

Great video Gentlemen! I'm still waiting for the tear down of the BYD Seagull! I also hope that you guys tear down the BYD Seal, Polestar 2, NIO ET7 and many more.

Very cool engineering very excited to watch, this guy really knows stuff. There is no need to attack any others car companies if you know stuff.

This is such a good video, I could listen to stuff like this for hours.

Love this content 🎉

What a pleasure to watch. Thank you for this crazy in-depth look at this battery.

4680 and LFL lithium Iron(no cobalt or nickel) batteries are becoming popular with Tesla but they still use 18650 and 2170’s. They offer more diverse batteries vs competitors

I love this guys look/suit. Very based. One cool cat.

13:50 that's not true, it take at most 10 minutes and also you can use it for 30 minutes, you can check the owner manual

Thanks. Terry is a smoother though less passionate speaker than Sandy Munro. I prefer a more technical discussion but Terry seemed to be holding back a bit in that area. The only blatant slip I noticed was 4860 when he should have said 4680.

I wonder if you checked the battery pack for torsional stiffness, how much it will twist? The foam is strong and it looks like the foam itself adds structural strength. The foam will also provide sound dampening, isolating and any part of the truck that gets banged, the truck won’t sound like when you strike an empty 45 gallon drum.

Sandy Munro has some serious competition going on here! 🤓

Great job. Thank you.

If you look at the coverplate for the battery pack when they take it off you will see that it is even more space than what you can see when it is off. For me it would be very interesting to see if the space is more than 80 mm i.e. prepared for one more layer of batteries... It sure look like it!

thank you. great showing all these insights. 👏

Did you get/promise/sell the KZfaq creator "The Limiting Factor" a couple 4680 cells?

Great work

Brilliant engineering.. I am amused by the "cranky old man" posters here who don't understand and fear the new technology.

Thanks for sharing VERY good work

Excellent presentation.

Amazing. Thank you.

I love how he explains it! 👏👏👏😍😍😍

While battery penthouse is protected at rear of battery, it would be far cheaper to put the penthouse and all the motor inverters and charge port up front in one high mounted position under the hood - rotate the HVAC unit 90 degrees to make the space. Up front, the HV electrics, including all inverters, could all go in one intumescent plastic box with two cooling circcuits. Each motor inverter is behind its own cast housing - a lot of expensive 'packaging' to be done away with. Charge port and 'bar'' cables would be very short if in the front quarter panel behind and above the front wheel out of the way of the wheel breakaway during SORB test. Electricity flow is near instantaneous. When a voltage is applied, electrons 'drift' slowly - about a millimetre per second - but the electric field around the wire is created at near the speed of light. Makes no difference to the motor if the data cable and HV cables from the inverter are an extra 5m longer. Bringing power out the front of the battery only requires small protective plates on the front of the battery. The coolant tubes at front require protection anyway.

Thanks! This was a great video.

Thanks for the inside look!! What is the pack? 7p50s x 4 units(pseudo modules)?? That’d land it in the high 700’s for voltage. Thanks again for the view.

This wonderful video shows the construction and functionality of the Cybertruck's high-performance battery. Thank you! - Countless parts form a complex system that can hardly survive autonomously. The entire car shows the technical limits of electromobility. - Instead of one Cybertruck, Tesla could make ten simple, efficient and affordable small cars that would be helpful to many people around the world. And because it does little to help people, it will probably fail.

11:20 Cross beams for side impact. I expected these to provide vertical support, so the floor doesn’t sag or rise. It also provides separation between the battery and the carpeting, right?

Great video, keep up with great work 😊😊❤❤

Does the Battery Management System (BMS) know the condition of each individual cell? Can the BMS control the charge/discharge of an individual cell, or does it look at groups or series? That's a lot of extra work to manage every cell individually. Wiring each cell, but are they applying individual sensors to each cell or doing that through the BMS? How would you control the charging of an cell in a pack? That would need switches???

Are the connectors at the opposite side of the penthouse only outputs (Rear motor, front motor, a/c, range extender?), meaning that the induction charger could be bi-directionel ?

love it

very cool, what about all the talk that the battery is only half full? Is there enough space for another layer of batteries in that empty space?

Thanks John, Terry and the Caresoft team. Does the "penthouse" that holds all the electronics have easy access?

15:00 This centre rib is contoured to the groove in the pan. The edges of this cover are separate pieces from the big flat part of the cover so counting the flat section, 4 sides and that centre rib, that’s 6 pieces to make the cover. That’s a lot! The Model Y had one piece and I thought the Cybertruck battery in the Munro video was made from one piece as well, with no centre rib (I may not recall correctly, I need to check again). That centre rib has a lot of round cut-outs. You don’t need that many just to hold the battery. Would there be another use for it for after it leaves the factory?

At 2x speed the info-to-video-length ratio becomes worth the time spent on watching. Thanks for sharing! :-D

So, Cybertruck battery is impossible to repair than Model Y batrery. Though it is split in four separate sections, which may help bring overall repair costs down vs. Model Y.

Lot of good engineering with focus on minimising risks. Congratulations to Tesla engineers responsible for this innovative battery pack!👏

Amazing.

14:20 He has those numbers backwards. It takes 10 minutes to pressurize and you have 30 minutes before it runs out of air.

If you put in 4690s instead of 4680s you can get 12.5% more energy in the battery pack - should be good for 10% more range (should still leave some crush space). That would be about 375 mile EPA range. I would love that since I deal with cold winter days and am interested in hauling stuff in the future too.

Nice job John going around & still learning new tech. Maybe you should bring Gary along? He seems bias against EVs & reluctant to even learn.

thank you for the insight...not quite as good as Munro. but always worthy of learning.

Any thoughts on how the future model Y update battery will most probably be?

9:50 The 12 volt battery on an ice car ranges in charge between 11 volts and maybe 14. I assume this truck battery has a sort of regulator to keep the voltage going to power the truck consistent, so there is no variation. I wonder how much variation the battery pack has? Would it go to 50 or 52 volts when fully charged?

Around 2034 we will we get a kick looking back at how humungous vehicle battery packs were a decade ago. A compact, efficient, affordable and scalable pack will be the final nail in the ICE coffin.

I deal with old hybrids, they're hell. If you chuck a 2000 dollar battery in it and don't take care of it, or leave the vehicle sitting basically, you have to replace the thing again. Electric vehicle is a thing you have to keep driving to keep the battery healthy (40-80%) charge. Ive taken totally dead hybrid battery and make them work again, but leave the car to long without driving it and you get stuck on the road.

The battery pack is displayed very nicely but it would be better to also have a battery expert to provide greater detail

Many competitors use Chinese and Korean battery packs as USA needs more battery factories as well as charging stations. The Cybertruck uses Tesla’s own design in house batteries 4680 DRY CELL batteries that are tabless. Huge toxic black slurry ovens taken out of the picture saving time, cost, and machine space.

The Model Y 4680 was essentially a failed venture. Not that any were made with the structural floor. And model Ys today are not made like that. They may bring it back once they have enough cells to share between Cybertruck and Model Y.

That is not a membrane, that is just a foam "skin" formed during foaming. Also it is impossible to inject that foam through such small holes, it would take a lot of time. It is just poured on top and flows through those holes inside.

I believe your guest Terry and host John McElroy are impressed by Tesla engineers and the work they have done, Tesla leads by about a generation or two over legacy auto in BEVs!😂

Anybody notice that now that they have EV sales down nobody is publishing videos of EVs catching fire, or people stranded in snow storms with no battery?

Speculate on the charge curve if the range extender goes in

20:30 I’d love to see sensors for the coolant to see where a battery cell fails. You may not tell which cell but you could tell which row the failed battery is in. Likely one battery would heat up all the water as it exits the pack so you know there is a failure. Maybe the electric current would tell you which row the cell failure is in?

With all that uneven surface at the top of the battery there must be some kind of floor panels to make the floor flat. No?

Find somebody that looks at you the way John looks at Terry @ 6:52

Motor tear downs please!

John, ask the question…. How does the compare to the 3?

that aluminum charger looks like it is a bus bar in a plane.

How are these big battery packs grounded?

One thing that's bugging me you keep saying that the battery management module "understands". Allow me to clarify, it does not understand anything. The vehicle and the battery both have sensors that communicate with the module. The module has logic written into it in code. The module then takes that sensor input and applies it to the logic program , that determines the relays to activate or not. There is no "understanding" happening. It's not AI , it's not even machine learning.

Wow Munroe better raise its game!

The extra space is for Tesla to pick up BMWs 4695 and 46120 orders if they default on theirs and they are cheaper than Teslas own 4680‘s. Just a precaution.

The penthouse seen at the start of this video, what holds the battery management system, the edge of it is contoured to follow the shape of the contents instead of being four straight sides. Why bother contouring the edges? I would have thought it would be easier to make it with straight sides. Do the contoured edges make it more rigid or something?

Truck has scuba mode pressurized battery pack to prevent water in battery pack crossing rivers

Autolinedaily has the two best teardown experts 9n their show ,CareSoft and Sandy of Munro Live, Legacy Auto should pay heed to thies experts if they are to survive the coming Chinese Auto BEV wave/onslaught!Tesla rules when it comes to INNOVATION in BEVs and its production, BYD and others are its heels. American Legacy auto are ,5 years and ageneration behind!

Yikes! The hot gas vent is only at one end? A modest 'thermal event' (normal people say 'fire') involving only a few cells at the opposite end will pass hot gas down the entire row, just below all the other cells in that row. Add to that the surrounding foam may itself be a fuel. Don't get me wrong. Any battery fire will almost certainly spread eventually. The goal is to slow the propagation and minimize the thermal energy and gasses that can enter the cabin while providing time for occupants to exit or be rescued.

It's 4680, not 4860

I was shocked by 150VDC vacuum tube B+ and it hurts

Just can not stop shaking my head 🤦‍♂at watching John McElroy looking so interested and excited and complementary of EV & Tesla. Just 7-9 years ago I had to stop watching any thing he did or Autoline because as auto "experts" they were literally laughing at Tesla and the entire EV industry. He and Autoline should do a public apology to Tesla and every other manufacturer that they were literally throwing 💩 at

This seems like a battery architecture that is impossible to troubleshoot bad cells. While it is impressive that this has been made to work (well mostly work, the range is still under 300 miles and significantly under in cold weather and/or towing), I wonder if this solution could be called practical. I'm reminded of the Ford Nucleon (never actually built) nuclear powered car as well as the turbine car (which was built). I suspect both could be made to work but are these solutions a practical way to run a vehicle for someone who is on the hook to buy it and pay to maintain it? And if Tesla goes under, it would be nearly impossible to run or maintain. I'm not sure what the solution is, but I just don't think this is it.

⚡️

Wait did John and Sandy have a fight and break up? Awhh. I'm thinking Sandy got too big and cut the cord.

👍

Ouch! That's one expensive fuel tank.

I’m wonder if elon is happy about to see all this

⚡️⚡️👍

Aks-u-ally water and electricity mix extremely well, and that's the problem!

This needs to be taught in American schools.

Emagine, so much tech here but Tesla is not static…changes will be made on the fly to make it better.

Like a more sober benign Monro. I prefer a bit more passion and anger.

Don’t touch! They touch everything.

Why does Tesla allow this. Are they not a consulting company that it will sell what it learns. Curious about this and what the end goal is?

Read “COBALT RED by Siddharth KARA…….

4680* 18:39

Rivian said they are going to a 4695 looks like that extra space is future proofing for larger cells.

The vehicle negotiates whether the charge plug is able to provide AC or DC with the EVSE before any voltage is allowed to pass through any EV plug. The vehicle does not measure the voltage source and then switch contactors. This is why the teardown/reverse engineering industry like Munro and Caresoft are not great communicators. I know people at both groups know these nuances, but it's embarrassing that they convey blunt misunderstandings.

Guy on the right looks like John Travolta (now)

Why is Caresoft tearing down teslas?
