Transcripts

hey boys and girls W welcome back to

Monroe live I'm here with Tom pet and

what we're going to do today let me

rephrase that what Tom is going to do

today is um is uh give you a little

Lowdown on what we've discovered so far

on the 4688 uh battery pack that's

inside of the uh the Tesla cyber truck

so I'm going to give you the one thing

that I was kind of curious about or

interested in and then Tom will take it

over because he's the expert so if we

look down here uh when we peeled off the

um so we've got Micah here and we've got

the green stuff there and even though

this is only U three three something

volts um I don't touch anything so the

one thing we can look at is that little

ball bearing down there uh which

basically is the blowout as far as I'm

concerned um if that cell goes bad it

has to uh vacate the gases that are

inside and so it blows that little thing

out on the other ones that we saw it's

got a um uh pop rivet for black lack of

a better word um and U and you can

notice too that there's some

configuration down here that we haven't

seen before today's video is sponsored

by

Weagle hey boys and girls welcome back

to Monroe live I'm here with Aaron

Weagle uh from Weagle Solutions

manufactured and believe me I'm sure

this is going to be a great tour anyway

Aon can you give us a little background

little something on you and tell us a

little bit about the company sure thanks

SNY um Aon Weagle president CEO of

Weagle formerly known as Weagle to works

and we just recently dropped acronym

because of all the different

capabilities that we now offer our

customers uh we're a third generation

owned business um we're my brother

sister and I are the third generation my

grandfather started it back in 1941 as a

tool and die shop and over the decades

and generations we've evolved from a

tool and die shop to a metal stamping

facility to now just doing a lot of

different manufacturing with the man

with the stamping emphasis today we do a

lot of patented R welding processes uh

assembly processes and uh we're into

molding now in in some cases so um just

a lot going on here because we want to

make sure that we are providing

everything that the customer is looking

for as a One-Stop shop place as we start

to grow and add on additional

capabilities and and expand our

footprint not only in Chicago but now

heading into Mexico in 2024 this is a

patented welding process that we

co-developed with two other partners in

the United States be able to to produce

the products that we're making for our

customer custom

machines and we're about to show you a

little bit of what this thing does but I

as an example

here we're marrying two different

aluminum materials

together to form to produce a a welded

component here so here's the after and

this is the

before so as you can see the parts are

being moved from station one to 2 2 to 3

3: 4 and then the robot will introduce a

new piece here and that process will

continue as we start the automation

process so the robot to your right is

locating the the flexible circuit

board removes the the backing to expose

adhes use a vision system to check

whether or not it's a positive or

negative Flex circuit board locates it

on the frame applies it so this is empty

tray so once this is full it'll come out

yeah we put a top on it and that's the

final stages where it's it's the

operator's responsibility to get the a

full skid out and keep always an or

empty tray of a full skid ready to go in

CU so anyway what we're looking at is

one of the pieces that's coming out of

this Minster here this 160 T thing so

we're looking at we're looking at I

don't know uh some sort of a connector

or or contactor and this is like

amazingly thin over over

here this is our 350 ton Minster and

what we're stamping out here is a thin

gauge I would say medium gauge uh copper

based material with tin plating once

more and this is a a thinner gauge bus

bar where is that done on this front so

we have a post operation on this

particular part where we're putting P

insertions into these into these parts

some of that can be done off press and

some of it can be done in D so we do we

have both we have both applications

really if you're going to do it in die

it really depends on the part design

which may or may not allow us as be

doing it in di so welcome to our ym

department at at Weagle so this is

really part of the process of how we

make all of our Progressive dies within

our facility everything is all designed

and built at Weagle and as far as the

Precision and where the the most

important part of the process is when it

comes to making our tools starts right

here this is a climate controlled room

68° once again year round all these are

MZ brand ym machines typically we like

to flip our machines every 5 to seven

years because the technology on these

machines change so quickly and just they

so much improve whether was just um the

speed of the machine itself or even the

uh the wire

consumption all right well um I have

never seen one of these yeah I I'm not

uh surprised

well this is brilliant Aaron I have had

a hell of a good time I gotta tell you

and I don't get stumped too many times

you got me twice so um I'm really

impressed with all the stuff you've got

going on here um I've just had an

amazing afternoon this has been really

really wonderful so thank you very much

for allowing us come here and uh and and

and basically videotape all this stuff

thanks for uh educating me on a couple

new tech I've never seen before and just

in general this has been brilliant thank

you so much thank you s I appreciate you

coming out I appreciate you coming and

seeing what we got going on here I mean

our family and our and our staff are

really proud of what we've been

accomplished and to be able to Showcase

that is great so um and especially on on

your show it's been uh it's got a lot of

notoriety and and we feel proud and that

we can even be here so if you want to

find more information about Weagle it's

uh

www.eagle.com and uh again thank you for

everything from my you know they yours

appreciate it thank you so much thank

you thank you and ladies and gentlemen

boys and girls thanks for watching stay

tuned they'll be more coming up in the

near future

bye okay so down on this end we've

started to extract some of the materials

so that we could get to the backsides of

the cells by the backsides I mean the

anode end where these vents are Sandy

just showed you um the first thing we

wanted to understand was how the pack

was organized in terms of s's and PS so

that was a relatively simple process um

you'll notice I'm very minimally pped

here today um that's because we

understand this pack very well right now

we know exactly where the potentials are

that are uh lethal if you will um so I

know that I'm working with 3.4 Volt

range here and there's nothing I can do

to get myself in trouble so that said

what I want to do is just quickly show

you the open circuit volt voltage of one

of these cells and show you how you

determine that it's a 7p I'm I'm sorry s

yeah 7p Arrangement so pretty simply

done you know I just take the voltage

between two of these and if you look at

the voltmeter there it's 3.39 volts so

if I start probing around here I can

determine things pretty quickly for

example yeah this one's the same this

one's the same this one's the same this

one's the same that one's the same and

so is that one so relative to this one

cell they're all at the same voltage

relative to one another all right so

that said um if I probe around further

it's pretty easy for me to infer that

each row of seven is wired in parallel

so again if I just use deductive

reasoning here I can figure that out

pretty quickly so the next question is

okay if I know that it's a 7p

Arrangement how many do I have in series

so I've previously done a measurement

and come up with uh

325.7 volts I think it was which is uh

what I would call the voltage of the

half pack so when we removed the

penthouse equipment um one of the things

that happen is the uh connection between

this side of the pack and that side of

the pack has been opened or separated if

you will however on the far side there's

still a bus bar that interconnects these

two so this entire array is still

electrically connected to this entire

array and in total that amounts to the

325 volts I mentioned so that being the

case I can go right underneath there if

I untape the terminals and I can measure

that voltage so if I take that voltage

and I divide my 3.39 into it I end up

with um exactly

96 and 96 is the number of cell groups

in series for half the pack and If I

multiply that by two for the other half

of the pack I get

192 so yes the configuration of this in

terms of s's and PS as we like to say in

the business this is a

192s 7p pack totaling out at 1344 cells

so pretty straightforward when you have

an understanding understanding of what

the parallel Arrangement is and you know

the total voltage involved and the

individual cell group voltages we're

thankful that the battery management

system does a good job and each of the

cell groups are relatively close to one

another so when I measure 3.39 And1 I'm

confident that a 3.39 on all of the

others as well so if I go out to a third

digit it's going to vary a little bit

between the different cell groups so

that said voila we know there's 1344

cells in this pack but what I also want

to do in this video was kind of contrast

what we've learned here on this pack to

what we knew already with the structural

pack from the model y so it was our

previous experience with this sort of

encapsulated battery pack and there's a

number of dis differences that might

seem subtle but are very meaningful for

us as we try to take this pack apart so

come over here and you take a look I'll

I'll point out some of the the

similarities obviously these are 4680

cells as well they have what appears to

be a nearly identical if not identical

cooling pipe that goes in between every

other row of cells so this cooling

channel here has uh a serpentine path

through each of the cells that are in

these two columns so the same for this

one same for that one now what's unique

about that is that I have six columns I

have three cooling pipes pretty

straightforward I run right down the

middle of two columns of cells

so what's different about this though

and it's kind of hard to see from this

Arrangement but what we have is a NP in

the model y so nine cells in parallel

which means that even though I've got a

row of six that means that one row of

six is combined with the next row half

row of three to create the nine and then

I still have a half row of three for the

next row of six to make nine so it's 6 3

3 6 6 6 336 all the way through the pack

you can imagine then if I was extracting

cells from one row I have to be

concerned with the fact that I'm still

electrically connected to half the cells

in the next row so it's quite a bit

different with the new pack here from

the Cyber truck in that at least each

row of seven is autonomous by itself I

don't have to worry about interacting

with the next row as I'm working on a

single row so I don't know if that makes

a lot of sense to everybody but it does

to me so that's what matters as we try

to take this thing apart so this is you

know where the similarities end this

pack is right side up relative to the

way it's installed in the vehicle this

pack is upside down relative to the way

it's installed in the vehicle that's

because in this case the cover's on the

top and in this case the cover is on the

bottom so we had to flip the pack over

but what that means is that all these

current collectors that you see here are

buried in the bottom of that urethan

where we can't see them we had the

luxury in the case of this pack where we

could Blast away we used a dry ice

Blaster if anyone wants to go back and

look at those videos um by blasting away

we were able to get to the current

collectors disconnect the cells one at a

time and then extract the cells one at a

time we don't get that luxury with this

one unless we do some rather invasive

surgery that we'd like to avoid well we

are well it's already pretty invasive

but it could get a lot more yeah I think

I think that what we're probably going

to do is try and cut away some of the um

some of the uh shielding and whatnot the

battery tray as it were and um and see

what we can do about removing some of

them but um I'm very doubtful that we're

going to be pulling out a whole lot of

these batteries these are really

um they're tough to get at and uh and

the cost would be astronomical so we'll

have enough for our own testing but I

doubt very much we're going to be

selling a selling a whole lot of these

well I was going to stop short of giving

away our detailed strategy but you heard

it here first yeah well that's that's

our strategy for now few more details

but um yeah generally speaking we have a

material we're able to break through the

polyurethane with we assume it's

polyurethane until it's tested um that's

because this was a polyurethane material

and we believe pretty strongly that the

big difference between the two is one's

pink and one's kind of the blue green

color you see so well that's the

from the color console color console

they they they've they've kind of gone

to se green here and and we know

historically they've always changed the

color slightly between different models

and vintages of of modules so you know

model 3 is slightly different colored

than our model y slightly different

color than the model S so all that said

um other things that are similar um yet

different there's a vent trough here in

this pack as well well but it's

comprised of these black trays that you

see here we've pulled one of these black

trays out just to show you what it looks

like and what you'll notice about this

tray is that it's pretty frail stuff

right it doesn't support a lot of

structure its intention is to provide a

spot to Route the flammable gases out of

the pack during the thermal runaway

event it serves another secondary

purpose if you will um that is very

important and uh we saw an example of it

on the other one I'll make an analogy to

but if there's a road hazard a rock a

pothole a trailer hitch whatever boat

anchor like boat anchor yeah exactly um

it can hit the bottom of the pack and

impinge on the pack and what you want is

a sort of a buffer zone for road hazard

safety so you don't puncture a cell

because you had something that protruded

into the bottom of the pack so that

being the case they've given themselves

oh probably close to an inch in toll

when you stack up all the materials um

of buffer zone for this passenger car

that's meant for the public roads yeah

if you go to an off-road vehicle that's

meant for stumps and rocks of every type

that buffer Zone's got to be bigger and

that's why you see that's such a big

space here all right so it is serving

that same purpose as the vent trough to

carry the gases out but it's arguably a

little bit more volume than you might

need for that um yet that extra buffer

for road hazard is really important for

an off-road vehicle well this one

actually even has more because the skid

plate on the bottom is actually raised

as well so this is uh about 2/3 of what

you're going to see it really comes up

to about here um think you mentioned

about 30 mm or so in total so that

sounds perfect for me um you know but

the mystery about couldn't they have

filled this up with more cells well you

know probably one of the things they

could do with a major retooling is they

might be able to go from a 4680 to a

4695 or one of the longer cells however

they really like that buffer zone and

for that matter they really like the

space that they have to carry the gases

out when there's an event so that being

the case it's not like you're going to

put another row of 4680 or another stack

of them or anything like that not

without impinging on either the

passenger compartment space or your

ground clearance of the vehicle so yeah

those are two pretty coveted parameters

as well so you're not going to see them

try to do that so that said yeah I'm not

going to say they can't add capacity to

this we look at these long troughs here

that are empty another comparison with

the malaw structural pack is that we had

the same sort of troughs here but they

were filled with this black sort of

really uh energy absorbing foam and I

assume that that served both an nvh

purpose as well as a side impact energy

absorbing purpose but you know it's a

guess well these things engineer yeah

this this doesn't really I don't think

this is going to be much of an energy

absorber cuz I can squeeze it and if it

was going to be you know like EP or

something expanded polypropylene that's

uh that's something that was in here

okay that but this not so much and this

is expensive and you'll notice it's

missing an action on the Cyber truck

along with the plastic tray now this

thing was eliminated pretty simply with

the simple idea of flipping the pack

over and just using the void area

instead of the tray and I like this

better because this gives me more more

volume if one of these things do blow

it's no big wow if you get maybe one p

one uh one uh parallel pack that all of

a sudden for some reason or other wants

to okay now I can exhaust all that gas

cuz I've got so much area here it's

incredible so I I like the idea of this

plus it protects the

it's going to make it tough for us but

it protects

Tesla's battery Integrity I mean uh it's

going to be difficult for us to tear

this thing to pieces and and expensive

this is kind of a subset of my favorite

spreadsheets some of you might have seen

in the past but it is a contrast between

the two different approaches to the

packs uh you'll notice that the model y

structural pack was a 92s 9p where this

is

192 7p uh the total number of cells is

drastically different between the two

packs we had 828 in this unit and now

there's 1344 in this one so um again

that also is shown with regard to the

voltage operating range there's quite a

difference this is a 400 volt pack and

this is an 800 volt pack again a very

gross generalization the industry uses

that doesn't mean that it's ever really

800 volts exactly except for maybe brief

moment in time it's really approximately

537 to 86 volts in voltage operating

range compared to the old one that we

are already very familiar with at 257 to

386 or so so uh again it's a doubling of

the voltage another unique feature of

this that has been touched on by other

people um I mentioned the half packs

this particular pack has the unique

ability to reorganize itself it's 800

volts as a normal situation but it also

has the ability to reorganize itself

into two 400 volt packs in parallel and

that's important because the charging

infrastructure is mostly 400 volts in

the United States so if you want a DC

fast charge your only way to do that

with this pack unless you have the lucky

chance of having a real 800 volt DC fast

charge station is to charge at 400 volts

DC and to by reorganizing the pack as a

a 400 volt pack dynamic when it

encounters such a charging station we

have the ability to fast charge this

with the obvious ability to fast charge

better if you encounter a real 800 volt

charging station so kind of unique we've

seen that feature before on the Hummer

kind of works in Reverse where that's a

400 volt pack and when it encounters an

800 volt charging station it can

reorganize itself as an 800 volt battery

instead of the two 400 volt batteries in

parall parallel that is now so anyway um

two different Roes to the same exact

sort of idea we'll be touching on how

Tesla does that differently in a future

video so uh for now know that they're

similar and sort of opposite in the way

they work in that regard so just out of

curiosity we haven't taken apart um uh a

Chevy

Silverado um now that has uh an extended

range is it 800 volts as well does it

reorganized similar to I am not as

surprised on the Silverado as I am the

Hummer if it's it's the same as the

Hummer then yes it can be 800 it's

normally 400 anyhow so there you have it

everyone that's uh again most of what we

know um stay tuned there's a lot more

where this came from absolutely thanks
