Inside Tesla's Cybertruck Battery Pack - Caresoft Teardown
HTML-код
- Опубликовано: 2 май 2024
- Terry Woychowski, the president of Caresoft, takes us on a detailed tour inside the Cybertruck battery pack, with particular attention to the "penthouse" that contains all the controls for the pack. He also shows how Tesla has future proofed the pack the range extender and inductive charging.
** At the 13:50 in the video Terry incorrectly says the Cybertruck takes 30 minutes to pressurize the battery pack allowing the operator 15-20 minutes of “Wade Mode” action. Here is the correct info: the Cybertruck takes 10 minutes to pressurize the battery pack allowing the operator 30 minutes of “Wade Mode” action. **

Munro has competition, this makes things more interesting.
Yeah shame he went ad-migeddon
MUNRO does it BETTER.
@@markplott4820 Not really, Munro is pushing a musk agenda all the time (probably because his retirement money is in their stocks), not even a single time is this guy trying to sell or promote tesla or musk, it's all technical talk appreciating the engineering behind it, which is the opposite of munro. This is so much better.
They're both good. Relax. They probably know each other. The host knows both of them as he worked with munro 5 years ago
So glad to have found out about this alternative to Munro and associates. He is way too biased for me now
This guy he is so well spoken and it's such a pleasure to hear him explain it all
too bad MUNRO beat hum to the Battery Teardown.
@@markplott4820I what way?
@@Stefan_Dahn - MUNRO did pack teardown BEFORE Caresoft.
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!!! 😂
I was thinking more Obadiah Stane from Iron Man
He’s just Staying Alive
And he is a pilot.
Sean Connery
Joe Biden seems to be very interested
It doesn’t take a half hour to pressurize the battery pack. there’s a half hour limit on the wade mode
Do you own a cybertruck and have used this mode personally?
That's what the screen says
@@BenefitOfTheDoubtInquiry So both can be true at the same time, right? It taking 30' to pressurize and wade mode being allowed for 30 minutes? What does the screen say, how long pressurizing takes? Does it say 30'? Am I understanding you correctly?
“WADE MODE DURATION IS LIMITED TO 30 MINUTES AND MAY TAKE UP TO 10 MINS TO COMPLETELY FILL THE AIR SYSTEM AND PRESSURIZE THE BATTERY PACK ONCE ENABLED.”
- Cybertruck Off-Road Guide
@@ericy.2108 finally. THANK you.
Where did you get the 30 minutes to enter wade mode from? I see less than 10 minutes time from all other sources.
They just didn't do their research in their rush to get the content out.
I think he got the numbers twisted. Its 10 minutes to pressurize the battery which could be used for 30 minutes.
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.
I agree that was funny, but the part he touched is normally directly connected to the charge port and touching the charge port is definitely safe. That's because the contactors that connect it to the actual batteries are always open when there's no charging going on.
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.
Agreed, since CT was design to be abuse. They found out that battery pack has more chance to get hit and leak. There's need to be someway to get water out
TESLA can already wade while FULLY submerged.
@@markplott4820 An owner tried that and the battery system shut down almost immediately. The CyberFlop had to be towed.
@@hwirtwirt4500Source or it didn't happen.
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.
Why? There aren’t any new technologies in those.
The Seagull got a lot of attention at the International Auto show in Thailand. 1 of 4 new cars in Thailand are electric. The Seagull will be significant for an affordable EV for the masses.
@@The._.Truth-.-making something up and typing it on your cell phone doesn’t make it true. BYD is a global leader.
@@tedg1609 Some of the cars he mentioned are old and not interesting enough to tear down. But the BYD cars are interesting enough and some of us remember the corrosion scandal with the Atto 3 (terrible names from BYD)
why , its another very CRAPPY Chinese car. ?
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
Owner’s manual doesn’t say how long it takes to activate but the screen and off-road guide do say up to 10 mins to activate.
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.
NO , 4680 Structural pack , prevents ANY twisting.
There will always be a little bit of movement in every direction. If they are checking the engineering, testing the amount of twist would be part of that.
It’s not so much to just check if this works. It’s to figure out what reduces twist and other movements like if the floor sags in the middle. When we know what works to achieve the results we want (like no twist), the next step would be to strip away what isn’t needed, to reduce complexity, have fewer parts, reduce weight.
So many cross bars looks like they are needed for structural support. The best would be figure out how to get rid of them. You get a flatter floor, reduce parts, make a bit more space. The structures for the seats and centre console look like they could be designed in a way to use this as storage space, for under-seat storage. There is never too much space in a car or truck. The Model Y and the other cars, same thing, a big drawer might fit under each of the seats. The back seat bench might lift up to store tools.
It's not a very robust design and relies on potting materials for stiffness. Cheap design.
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!
The extra volume is for safety in case the battery is dented from the outside, the damage would have to travel far enough to touch the actual cells.
@@Sal3600Source?
thank you. great showing all these insights. 👏
Did you get/promise/sell the RUclips 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.
Brilliantly cheap engineering.
Boomers are scared easily from high technology
@@BryceLovesTech Boomers developed 99% of the technology you're currently using.

@@Sal3600 Yes, and if you had a clue it would be obvious.
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.
Great comment! 👏👏
That wouldn't make sense because:
- Tesla wants to have a big frunk, and this would eat into it
- Tesla bases its serviceability on the frunk - by having a frunk, you get unobstructed access to all the under-the-hood components by simply removing the frunk. If there were high-mounted components in place of the frunk, you would have to remove them in order to access the rest.
- You need to have a battery penthouse of sorts anyway for the pack contactors and BMS. You might as well extend it to house all the components in the way Tesla does, as it's very convenient waterproof space which brings down the cost of the components and connectors inside
- If there was no battery penthouse where it is now, it would be unused space. Some EVs have unused space at that location because they don't have that penthouse, and it does look pretty bad from a design standpoint.
@@celeron55 without the penthouse at the rear, there will be more space for other stuff in the rear. Trunk might lose a bit of space. HVAC would be organised a little differently. Battery is in 4 parts, so four sets of smaller cables would run from the battery to the upfront HV box. All the contactors would be in the HV box. A data cable would run from each of the four cell monitoring circuits. The battery will have fuses. A HV box up front with all the motor inverters would lead to consider material saving and space reduction in the vehicle for HV equipment. The HV box would be serviceable and circuitboards replaceable.
they did this for FRONTAL impact compliance,
Na, better in the back.
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.
+800v 4680 Structural.
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?
good point but you are both correct. seats need strong mounting points, these beams great for that and additional structure for side impacts.
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???
No and no.
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 ?
NO , it wont be.
MUCH more Efficient DIRECT V2H connection , hardwire.
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?
I doubt it. The extra volume is for safety.
That talk is based on facts or BS?
Thanks John, Terry and the Caresoft team. Does the "penthouse" that holds all the electronics have easy access?
The penthouse is accessed from the top of the battery, probably from the front trunk by removing a plastic cover to get access.
@@hwirtwirt4500 I think the penthouse is at the rear of the truck. Probably somewhere under the bed of the truck.
@@59seank It could be, It should be accessible in either case.
MAINTANANCE free Battery pack. & MOTORS.
let it sink in.,
My guess is the penthouse is located under the rear seat bench or slightly behind it.
All these parts look like they have the potential to be reduced in size, maybe even miniaturized. If nothing else they could be made flatter to reduce the height of this penthouse. When they do that, they might stop calling it a penthouse?
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?
No, it looks like I was wrong. The entire cover is one piece and that centre rib is a second piece.
At 2x speed the info-to-video-length ratio becomes worth the time spent on watching. Thanks for sharing! :-D
True for just about every video on RUclips these days
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.
That foam that prevents the repairability reduces the likelihood that the battery will need a repair. It also thermally isolates the cell to help prevent thermal runaway should one cell fail. So pick your poison.
ALL Tesla motors & battery pack are ZERO lifetime Maintenance.
model Y & CT Structural pack , take to NEXT level.
@@danharold3087 The potting is for strength and allowed engineers to use less steel in the construction (cost savings at customers expense) , has nothing to do with reliability.
@@hwirtwirt4500 Trapping the cells and their connections in rigid foam reduces vibrations which can ruin the connections between cells. It also as I stated helps reduce heat transfer between cells to reduce the chance of thermal runaway.
@@danharold3087 It makes heat dissipating for the batteries worse and repair next to impossible. It's cheaper than building a solid battery case that's removable for service and repair. The idea of using the top of the battery case to mount seats is another cost saving design feature. Mechanically and electrically it's a compromise but it's cheap. The worst part of is the fanboys are too incoherent to realize its not a good design and just keep repeating bogus talking points provided by Tesla/Musk shills.
Lot of good engineering with focus on minimising risks. Congratulations to Tesla engineers responsible for this innovative battery pack!👏
The big downside is, that it is not repairable nor recycleable.
@@Stefan_DahnThese packs are recyclable. Tesla has agreement with sub suppliers in North America, Europe and China that specialise in safe disassembly and recycling of Lithium-ion batteries. For potted types they grind them down more or less as is and then separate and sell the raw materials.
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.
No, you would hate that, as you would have no heating/cooling/preconditioning of the pack.
@Stefan_Dahn what do you mean? This is excess space on the bottom of the pack, left to help make sure offroading doesn't accidentally destroy batteries. Another key option - taller LFP fill of the pack. Likely going to be what goes in for the future low price model.
Nice job John going around & still learning new tech. Maybe you should bring Gary along? He seems bias against EVs & reluctant to even learn.
Gary is just too negative and quick to react instead of 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?
Cheaper.
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?
TESLA now using 16v Lithium in all vehicles , except CT which has 48v Lithium battery.
I don’t think the ct uses a 48v accessories battery. I think it simply regulates a steady 48v sourced from the main pack. A typical lithium 12s 48v pack would run roughly 44.4v to 50.4v from empty to full
@@justinmallaiz4549 - MUNRO shows the 48v Lithium battery , as compared side x side to TESLA 12v lead acid, Tesla 16v Lithium & CT 48v battery.
very Significant SAVINGS in Weight /compactness.
@@markplott4820 ahh ok cool, I must of forgotten that
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.
Nope, there will be no great revolution that fast as you imply. VW has modular modules, but this takes more weight and costs. Tesla sacrifies that to the extreme in the CT and Austin-Y with the plastic-brick-battery-pack.
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
Agreed. All that BMS talk is true of any powerful device with lithium batteries. Would be interesting to see whether the DC-DC unit and inverter/charger can be replaced in the pack. I rather suspect Tesla will want to sell a whole new battery for every DC-DC failure. Most company make those components serviceable.
@@Miata822 Well, the power conversion unit is the silver box you can plainly see. It's definitely replaceable, as are the contactors as they are inside the penthouse. You can see how the penthouse top cover has been removed without damage, so that cover wasn't glued on - i.e. the penthouse is designed to be serviced.
@@celeron55 I agree that these components should be possible to replace, but Tesla has history with this kind of thing and the 48v system is both novel and heavily used.
@@Miata822 48 Volts is and isn’t new. The transition to higher voltage automotive DC bus has been going on for 20+ years. When power steering transitioned to electric assist, the racks were designed for 42 Volts. I’ve been looking for an SAE paper which explains the 42 Volt choice. 48 Volt bus has been the norm in telecommunications for 100+ years. OEMs didn’t get on the bus with 42 for other peripheral devices. If I recall, _Popular Mechanics_ ran an article back in 2009 titled _What Happened to the 42 Volt Car_ ? It will be interesting to see if 48 Volts catches on. The military and heavy duty trucking use 24 Volts. In 2024, it is possible to create sub busses for whatever one wants because DC-DC converters have become inexpensive.
see Jordan the Limiting Factor.
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!😂
TESLA dosent have Caresoft on speed DIAL.
TESLA does have Sandy & MUNRO on speed Dial.
@@markplott4820 Sandy is a tesla shill.
@@hwirtwirt4500Bought from Musk petty cash of a day. Munro constantly lacks money.
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?
Funny how that works.
It probably cost a lot of money to get all that FUD so widely published.
Seen it all before on Monroe live,it’s strange when people see something and think that’s a good idea I will do the same,problem is it’s old news 😏😏😏😏
Given that winter is over, fewer snow storms are being reported too.
Funny that often people freeze to death or suffocate from ICE fumes in ICE cars during snowstorms and it hardly makes the news , people have short memories!
Teslas Stampings are the way to go, simple to assemble and leads to easier and faster ROBOTIC ASSEMBLY, Oh did I mention the Tesla Optimus Robot will be part of Elons vision of his manufacturing process? TRY UNIONIZING THAT FELLA!
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?
I think they have such high confidence in the cells that make it to the pack, they don't plan for individual repairs
The BMS can monitor voltage cell by cell.
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?
Discharged to ZERO then Grounding wire , to prevent recovering charge.
Thanks for the response. I’m inquiring when it’s running, not when it’s being disabled for tear-down.
@@DougWedel-wj2jl It seems they are not. Just Isolated. Typical ice cars run the 12v negative terminal through the car structure just to save wire. I suspect a 800v negative battery terminal could probably discharge a deadly amount of power through, say a grounded power tool for example
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!
That won’t happen until lazy $andy gets a engineering degree.
MUNRO did CT battery Teardown MONTHS ago.
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?
It's the opposite. The contour is to have clearance for the wheels and suspension. The component inside is then designed to fit into the contour.
The sides or walls of the penthouse appears to be a cast piece, not pressed from a sheet of metal?
@@kazedcat No, it doesn't go that far back. It's just carryover design from 3/Y.
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!
Don't forget, practically every submarine ever made uses battery power for propulsion when submerged.
they use DUNK tanks to Extinguish BEV fires.
This needs to be taught in American schools.
American schools are now WOKE.
and pro Hamas & Hexbollah.
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?
Allow what, disassembling a purchased vehicle? Nothing illegal or shady about that.
@@hwirtwirt4500 never thought it was shady. Just surprised it’s ok by law to do that. Proprietary information. I guess it’s ok. I guess patients cover any issue. Awesome videos I was just shocked
Read “COBALT RED by Siddharth KARA…….
Why?
prussian blue.
4680* 18:39
Rivian said they are going to a 4695 looks like that extra space is future proofing for larger cells.
RIVIAN still cant FIX very CRAPPY wields in 2024.
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?
