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
for watching bye
