[@DougWedel-wj2jl]

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.

[@markplott4820]

NO , 4680 Structural pack , prevents ANY twisting.

[@DougWedel-wj2jl]

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.

[@hwirtwirt4500]

It's not a very robust design and relies on potting materials for stiffness. Cheap design.

That talk is based on facts or BS?

[@jonpower0]

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???

[@Stefan_Dahn]

No and no.

[@whattheschmidt]

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.

[@Stefan_Dahn]

No, you would hate that, as you would have no heating/cooling/preconditioning of the pack.

[@whattheschmidt]

@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.

[@peteregan3862]

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.

[@deltajohnny]

Great comment! 👏👏

[@celeron55]

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.

[@peteregan3862]

​@@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.

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.

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.

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

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?

[@kazedcat]

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.

[@DougWedel-wj2jl]

The sides or walls of the penthouse appears to be a cast piece, not pressed from a sheet of metal?

[@boostav]

@@kazedcat No, it doesn't go that far back. It's just carryover design from 3/Y.

Hi guys love to see these kind of videos . But I Honestly wand to give you positive feedback . 1, you don’t want to talk over one another 2, more details . Example have other staff around . Be organised to move the Rotisserie to the position of how the charging cable would look from the battery in its flat position . . 3, don’t skip over important things 4, honestly your video’s need reworking imho take a leaf from 🍁 munro live . . As over the years I’ve given them loads of advice . Good luck hope you take it onboard Ps it’s hard to keep focused you need structure and don’t waffle . Kind regards kevin 🤞🏽👍🏽

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.

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

[@markplott4820]

RIVIAN still cant FIX very CRAPPY wields in 2024.

[@preet6936]

love it

[@carbondragon]

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.

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.

[@Stefan_Dahn]

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.

[@garyrooksby]

Amazing.

[@citizenblue]

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

[@davidmenasco5743]

Don't forget, practically every submarine ever made uses battery power for propulsion when submerged.

[@markplott4820]

they use DUNK tanks to Extinguish BEV fires.

[@jcizman]

Ouch! That's one expensive fuel tank.

[@kb8570]

This needs to be taught in American schools.

[@markplott4820]

American schools are now WOKE. and pro Hamas & Hexbollah.

[@Derpy1969]

Don’t touch! They touch everything.

[@timat6656]

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

[@cryptodegensolana]

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

[@frankiegarc5675]

Ok why are you teaching and touching the batt pack without safety high voltage gloves??? Wow

[@FrankGallagherr]

Tesla is the best car company ever! No gas stations, No oil changes, No smog check, No corrupt dealership, No catalytic converter and as fast as a $650,000 Lamborghini .

[@BryceLovesTech]

I love my 2013 Model S

[@simonfisher836]

Guy on the right looks like John Travolta (now)

[@TeamBehrens]

Why is Caresoft tearing down teslas?

[@grega4450]

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?

[@hwirtwirt4500]

Allow what, disassembling a purchased vehicle? Nothing illegal or shady about that.

[@grega4450]

@@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

[@mymelt1770]

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