great to see Munro Live getting ad revenue, can only help the channel get better. Not sure how it can get better, thanks for sharing, as others have said, this is a highlight of my weekday's during lock-in.
"yes I am huffing and panting because it's hotter than blazes!" We really appreciate what you do :)
Mrs Monroe also Appriciates all the Huffing & Puffing.
Best part of the day!
mine was 10 minutes ago on pornhub before i came here
5:30am in LA and thanks for bringing the classroom to the house livingroom 👍🏻 awesome engineering content. Thanks Mr. Munro
Thank you Sandy for your hard work and dedication. It's really great to listen to an expert on a great piece of tech, love your videos. I hope Tesla model Y is not the last one you will work on. Stay healthy, live long and prosper!
This will definitely not be the last one! We're currently working on planning what comes after the Y is done. Contemplating bringing in some products from different industries outside of automotive as well. Thanks for tuning in!
Now begins the delicious part...
now begins the icky part - Brent Spiner.
As an engineer I love your videos. I hope they continue on even after the model y
Thank you for uploading new Videos frequently 👍🏻
He didn't ask us to tip the cashier's...I feel cheated on
Two cashiers have already refused my tips.
These people are true heros and need a parade, along with the nurses and doctors.
You actually read my mind wtf
we have a nectar app which allows us to tip the nhs here in euro land....
It's like he doesn't care about cashiers at all!!! ;)
George Choquette im a nurse and i take your tips anytime
Thanks for the update Sandy. I'm liking the model Y more and more as I get to see how serious Tesla was with the construction. ...tiped my cashier when I went shopping today, and I could see it was appreciated.
Glad to see you in proper high voltage PPE. There are far too many videos on TH-cam of people treating 400V batteries casually.
He needs Rich Rebuilds in there with a kitchen knife to disassemble that.
or speedkar99 he is the best!!
Please start a Rich rebuilds teardown with welding critique
That stuff makes me cringe. We have no way of knowing how many deaths and terrible injuries have been caused by viewers inspired by Rich and others with their casual attitude toward deadly DC voltages. A battery that can deliver hundreds of hp to the wheels can also dissipate that much power in your body.
@@Miata822 I think we know zero deaths or significant injuries have happened since the news would have run constant headlines about it for days. Anything negative related to Tesla is big news.
@@Miata822 That's bullshit. Dropping an engine while you're swapping it out on yourself might kill you, so anyone doing a video on a gas engine repair is a criminal? Free climbing might kill you, so let's ban all the guys who do funny videos about climbing...let's keep adding to that list.
If someone doesn't get that the "funny attitude" is just part of the show and not actually the way to go, that person has already way bigger issues than remotely getting a crashed Tesla and electrocuting themselves.
Let's go to the real point: there is no real danger, the only reason Tesla fanboys say this kind of thing is because they're mad at guys who do that sort of repair stuff and point out Tesla's terrible service and long term support.
As a guy that likes Tesla very much but surely is no fanboy, i totally appreciate Rich Rebuilds. After all, if we only talk about the amazing parts of the Tesla world, the bad aspects will never improve.
Wow Sandy. This content was already good. It is getting amazing! Great job!
Thanks for these videos - they've been a really interesting insight into car design (I've worked on cars for 30 years in a private capacity), as well as specifically into the Model Y. Made a (small, sorry!) donation via your shop. Hope everyone does as you've been great viewing.
Every little bit counts! Thanks for your support and for tuning in, Darren!
Another great video from the team. Good work, we are learning a lot from these. Thank you so much.
Loved today’s video!
Thank you Sandy, nice job!
Mr. Munro, you're a class act. Love these videos.
Kudos to bringing this info to the world!
Great video Sandy. You're at natural for TH-cam.
Love the "Blast Shield"... It's a riot! :)
there Googles do nothing.........my eyes Burn - Rainere Wolfcastle.
Munro needs to get a current production model 3 and see how many of these changes have already been added to that assembly line. Tesla doesn't do model years. The model three there are comparing it to is an early production from 2017 I think.
Wok buy him one and he will
Smarter Than You He could buy a used one, re-assemble it after,sell it, and it would cost very little overall.
He’s only holding onto the Teslas he already has for consulting purposes.
@@bob15479 except ofcourse for the cost of his engineers to disasemble and assemble the car, the analysis that needs to be done, and that they can't do any other actual work when working on that... yeah no cost at all. while i'd like a teardown of a current M3 i realize that its a business not a charity be glad that they show us the vids from this teardown
I was thinking the same thing.... I bet the battery sled is exactly the same as current M3.
Mark Brand so bring him yours, pay the labor for disassembly, analysis and reassembly.
Or if you’re too broke to buy one (which is likely since you don’t understand cost or the fact that they are so far retaining 90% of value at a year old) talk someone into donating theirs and having it returned sans warranty
Thanks, Sandy.
Crazy stuff ! Blows my mind .
Thank you mr Munro.
Now my morning is complete.
I couldn't be further from being an engineer, but your presentations are even to the layman, enlightening. I
Donated to Patreon because this CONTENT IS AWESOME! Can you elaborate some components on laymans terms now that we are approaching the "belly of the beast"
Thanks so much for your support! We will try to be as specific as possible, but if there's something in particular you want to know or have clarified, let us know. Thanks for tuning in!
@@MunroLive well like some others have said, you could consider making a new series by opening up the latest model 3 from the factory line (see did they improve compared to the first one you did) and sell access to that series for patreons only to fund the project
Many times in these videos Sandy says that bolt dimensions are identical as Model 3 and they did differently this and that compared with Model 3. And I'm just wondering, if he did look on current Model 3 if it is really true, I'm just wondering how many of these different Model Y parts are in Model 3, which is going from production line right now.
Maybe if someone gave them new model 3 to see
@@635574 www.teslarati.com/tesla-model-3-teardown-analysis-sandy-munro-threatened-lawsuit/ like that one.
You can almost guess: the parts that are easy to retrofit are probably in the new M3's already - others, like those that depend on the rear aluminum alloy casting aren't in - YET - the new mega ton stamping press which they are installing in Fremont, however might be for a leapfrog casting more encompassing than what is currently for the Y (3 pieces). Elon Musk mentioned there were TWO of these mega die-casting presses in the world, one made in Italy (probably the one in Fremont now) and the other in China (for the Shanghai MIC Model Y).
Edit - not stamping but die-casting presses - thanks @David Elliott
He is comparing the release version of M.Y to the release version of M.3. Imo its a fair comparison, even if the M.3 of course also changed since that time - maybe even in part due to his input. Showing all those changes and improvements is not intended to be a "do i want a M.3 or M.Y ?" decision help, but more an analysis of the technical challenges and how tesla solved them then and now.
@@nycandre The mega machines mentioned by Elon are high pressure DIE-CASTING machines.
I see a new video. I click.
Great watch guys , power to the elbow
As a former production engineer, thanks for reliving my nightmares Mr. Munro.
Camaraman: Sandy thank you for your thoughtful and comprehensive analysis. A request: please use a cameraman that is knowledgeable on how to shoot videos. This last video was constantly moving, it often left you out of the shot and was constantly zooming in and out. It made it difficult to watch.
PS I hope the video of Tesla's production line was helpfull
OK - maybe today was a little choppy, but all the other videos were fine ...
Appreciate the feedback, Emilio, we're definitely working on improving. Thanks for tuning in!
Sandy, could you point out source of the battery breather "pops" that M3 owners are very familiar with? Will it be corrected on the MY?
I suspect it's not the breather itself that is making the 'pop', but rather the large metal panel flexing that makes a sound. The internal pressure is supposed to be controlled by the breather but if the rate of pressure change exceeds the capacity of the breather (I've only heard it while supercharging when a relatively large amount of heat is generated quite quickly) a small amount of pressure can build up, causing the aluminum to deform and 'pop'
@@sooocheesy Ah right that makes sense. When it's freezing out it's even worse. As I commute to work my car thunks all the way down the highway as battery warms up. I just hope after a couple years of thunking it doesn't cause stresses and fails.
It's probably a panel that could have benefited from stiffening ridges. Maybe some anti drumming mastic mat would stop the popping. Then again - strippng the car to get to it...
Yep it's a model 3 pack on the outside and mostly inside, going to be interesting to see if they made any other changes!
Great Stuff!!!! Keep em coming!
Awesome video guys
Love your videos!
Would be great if there were video cuts only where absolutely needed. I like the flow of the way Mr. Munro speaks, cutting pauses interrupts it, please consider it
Appreciate the feedback and thanks for tuning in!
Another day, another great Munro video!
Thanks Sandy! Knowledge is good, so you can mess with a Tesla battery and be fairly comfortable knowing you won't experience an unscheduled human disassembly event. :) For us dumb observers, it's pretty exciting watching what you do. Stay safe!
I like the pointing stick. Lol
Model Y E24: Opening up the High Voltage Battery (without dying) and Comparison MY-M3, Pyro Fuse
He didnt watch how Rich rebuilds opens up Batterys i guess xD
Sandy: I'm huffing and puffing because I'm hotter than blazes". LOL
Me: Humm, I woke up to snow today.
Hi Mr. Munro, thanks for your amazing dismantling videos, very interesting!
Question: for safety purpose do you process a deep discharge of the battery pack before dismantling it? Or is it still fully charged?
Amazing!
Pause at 1:12 to examine the large, revolutionary aluminum casting. It appears to be made in two halves because you can see a gap or groove down the center at the front and back of the casting. The other thing I’m wondering about is the seat mounts on the battery control module cover. Does this mean the seats must be removed any time the battery is removed from the car? Also, are there 4 more seat mount locations on the chassis to the left and right of these mounts?
2 Things, 1: definitely forgot to say tip the cashiers so im sad now 2: someone mentioned a rich rebuilds tear-down. that would be so legit. In my head at least.
and Sandy calls it ' The business end' :)
Hello Sandy, in your description of the components under the AL lid I am missing a reference to a converter when AC-charging takes place. You only pointed at the DC-DC-converter that comes into effect when the charging current is DC, right? Or could it be that this big housing also hosts the AC-DC-converter? Thank you for your answer.
Can't wait for Munro to show up in a Hazmat suit.
the parts listed as eliminated: are you sure they were not forgotten during assembly?
😂😂had a few bolts missing from the bottom of my car. Not surprised what else might have rattled lose
Just an FYI, Tesla stopped using the foam padding on top of the battery pack a while ago. Sometimes in 2018.
Hi Sandy.. This Friday I'm getting a haircut and will pay double +tip. We're going to OutBack for Clam soup, Steak n shrimp and 2 Jack Daniels OTR...We'll be double tipping also.. I am a Field Electronics Technical Specialist for GE Healthcare and have not been impacted by the stand down.
I wish I could get a haircut I'd tip 3x
good stuff
great video. Does the pyro fuse protect the system from over current in the case of a battery short and if so, what sort of current would cause the pyro fuse to blow?
I love their design philosophy, they are obviously thinking in advance to be able to standardize their battery "form factor". The batteries are lasting insanely longer than most imagined though, so battery replacement looks to likely be a non-issue. The interesting thing will be the possibility for upgrading your battery to a dramatically better energy density unit in the future, and the software to support it is easily deployed ahead of time.
TexRobNC - With the exception of the Leaf (because Nissan beancounters decided to eschew thermal management), EV batteries seem to last longer than anyone expected.
Sandy, the ‘My Tesla’ app shows the Y battery capacity is bigger then the 3 battery.
Please talk about this. 👍🏻🇺🇸
72 va 78. I'm also curious to why
All Chevy Bolts that have>ever< been produced are now in a massive recall. Until battery replacement, owners are not supposed to charge fully, deplete fully or park a Bolt inside, for fear of fire.
Apparently, the Bolt has no ability to monitor the health of an individual cell in its complete battery pack. Otherwise, Chevy would be able to run a diagnostic to detect which Bolts have the issue.
Kind of like a "check engine light" but for the battery itself.
Here's my question:
Is there any EV manufacturer that has this type of cell level monitoring in its battery pack? Tesla? VW? Anyone?
I've driven a 2013 Nissan LEAF for 8 years, as I think about replacing it with a more modern and longer range EV, this is something I definitely would like to know before I buy.
Mark 3:15
Are we looking at resistance or cold welded stand offs (4) ?
You know he will be a real U-tuber when he asks users to click the like or dislike I do not care but click the SUB and bell before you leave to get notice of other videos .LOL
What is the available 12V power seing the DC-DC components? What would be the usable power if we would put an inverter to harvest an AC 120v?
Thanks Mr. Munro.
As someone who works on high voltage equipment regularly (20kV+), I had to chuckle at the amount of protective gear worn here. I think the max voltage on that pack is maybe 400V.. and while it would zap the shit out of you - possibly resulting in death - if you touch the wrong thing, it isn't going to jump across the air and attack your face with a sudden lightning bolt.
Accidentally drop a metal object and the current turns said metal object into a rapidly expanding cloud of molten droplets. They make nice burn marks on your lab coat, but are hell to take in the face. I think it's also a "don't try this at home without proper gear, boys and girls" kind of thing as well.
I wonder if the foam was put in because of customer complaints of banging coming from the pack during supercharging or cold weather.
Anybody notice that Mr. Munroe likes to throw things on the floor?
Sandy...never fret
Cuz I never fail to tip my local dancing girls
My questions are a little late wrt this video; however, I thought I'd post in the hopes someone is still monitoring comments and may have the answers!
1. If I were to dent the underside of one of these packs with up to 1/2" (12.7mm) dent, caused by a rock strike, would said dent compromise the integrity of the pack?
2. Can Tesla service centers diagnose the effects of said dent(s)? to determine whether the HV pack needs to be replaced?
Mr Munro, that pyro switch probably disconnects all high voltage not just two batteries. Because batteries wired in series to get the high voltage if you open a circuit between the sets of batteries ... it will shut off the current on the entire block. There are probably like 4 blocks at ~90v each - giving 360v. I am willing to bet they used common 360v industrial ac motor [at least initially pulse control].
Dear Brian, Tesla motors are far from industrial AC motors. Check the Munro video about electric motors and you will learn that the rear Y motor is a permanent magnet one, with a special set of magnets used to bend the magnetic flux in a very uncommon but affichent way. That motor has been developed for the 3, the Y, and the Semi by Konstantinos Laskaris and his team of fellow researchers in Greece. Those guys are the best EV motors engineers you can find on the planet ! And, with a past as electric engineer having developed my own EV and a variable reluctance motor during the 20th century, I know a bit about e-motors...
That is not what I said or meant. I was pointing out that the pyro disconnect all high voltage. And they probably started with 360v motor.
Question: what are all the red (and sometimes green) stickers for on all the parts? Is that so you can track which parts have been catalogued?
yes they add those themselves
Wait, you don’t take this all apart with just a butter knife? ;) A lot of small cost savings here that the end user would never see/notice. Seems like good ideas all around.
I heard the Model Y the installed a battery warmer like previous Teslas. Wonder if its resistive or uses the heat pump instead of the motors like Model 3. Or is it the same?
It uses the heat pump
I forgot to tip my waiter because Munro didn't remind me!!!
I would like to buy 1 Tesla battery (from inside the pack, there are thousands) for 10$, are you gonna sell it?
With that my phone will finally be able to last more than 2 days
Second that, but it's probably too difficult to pry them apart. Take a look at the Model 3 pack and you will see there is bonding foam everywhere. th-cam.com/video/64_iBKLSnGA/w-d-xo.html
You'd have to dissolve the foam and then de-solder everything all the while making sure never to touch anything with metal. I suppose, Munro and associates have better things to do.
I want to buy about 1300 to 2000 thousand for a project, bulk pricing?
Oh awesome, finally got a commercial. Looks like it’s TH-cam approved finally. Whooo
The model 3 pack had 4,416 x 21700 cells...if he sells them at $15 each, he could make enough money to buy another Tesla model Y performance. $20 each, could buy a tri-motor Cybertruck to take apart.
Good morning, the vidéo Model Y E22 is nottranslatable in franchement, please modify. You do very good job.
Is this the last video by Sandy before he got electricuted by Model Y battery and became a superhero?
Is that an i3?
Is it a Leaf?
No, its TeslaMan! Swoooosh...

Why would the 12V battery wires need to be so thick? I would not expect high current to be needed at 12V in this type of system.
Doest foam degrade over time? In 5 years it become brittle and break apart ?
Sandy, did you ever consider reaching out to Jay Lenos garage for an episode? I know he 3d prints a lot of parts he can't find for cars, so I think you guys would have a lot in common. Also, walking around his garage would probably be better than Disneyland.
What is the purpose of the three fuses?

Sandy Munroe ROCKSTAR. Please go to TORGUE NEWS. Their show today was about How To Work at TESLA . Their advice was for person was to work on old car. MY ADVICE WAS DON’T WASTE YOUR TIME TO GIVE A BRAKE JOB ON AN OLD CAR. WATCH SANDY MUNROE LIVE. You and others will get a kick out of my observations in detail.
i never got sick from a bad camera job until today. i wonder if they just chose the guy with the worst had shakes in the company, or what?
also, half of the video, Sandy points to something and the camera man is just recording something not relevant.
Emanuel Eni Keep in mind they’re filming this on a smartphone, when you and I are used to gimballed cameras. The channel is just getting started.
@@bob15479 That is correct, although the iPhone 11 is pretty forgiving! And Emanuel, thanks for the feedback, we are definitely trying to work on improving. Thanks for tuning in!
I'ld like to see your videos using wide-angle camera, hope it would be better to watch
Any obvious reasons why the Model 3 reports 72kw and the Model Y reports a 78kw pack?
Wow
DC to DC converter? How he described it,sounds like a DC distribution module.
You have to keep in mind that the only power going into the car is high voltage DC into the main pack, which then gets converted down to 12V (and possibly other voltages) to operate the computers, fans, etc. So technically because the input of that module is high voltage, and the output is low voltage.. it's a DC to DC converter.
They should just put the battery in a clamshell casting and be done with the floor.
Are you going to drain the battery or just disconnect it?
Hopefully he keeps the pack at 40-50% soc, for stable storage.
What's a "Temrinal" Cap? At time stamp 5:41.
The word capacitor is often abbreviated as 'cap;' they had probably been connected across those high-voltage switches to protect the switch contacts. When automotive ignition systems had employed a cam-actuated switch (points), a capacitor reduced erosion due to electric arcing of the metal contacts.
@@brothervance1932 I know what "Cap" means. I was talking about the word "Temrinal", that was on the screen. Is that a brand or did they mean "Terminal".

thank you Ladies and Germs. .......don't forget to Trip...……..Tip you Watresses.
With the protection he is wearing, does that make it reasonable for tesla not to sell spare parts due to the fatality of working on a tesla without protection?
Those thin foam strips scream CHEEEEAAAAAP! After two years in the elements, those cheap strips will disintegrate.
Its likely the latest Model-Y already has (minor) changes different to this one.
that's the correct way to fight corona
Please oh PLEASE tell me about that helmet you were wearing at the end. Is it a high voltage safe helmet or a welding helmet? P L E A S E ,........
Can anyone elaborate on how the Pyro switch works?
First hit on Google search. There's a pyrotechnic charge in it that severs the connection. It's triggered usually by the same signal as airbags.
It's an explosive link. To be fair' I'd have thought there would be three to separate the battery pack circuits into four.
@@iLoveTheseRemoras Ahh right I get it - thanks! Sorry for not googling, I assume it wasn't common so asked here, clearly should have googled first!
@@dsmclaughlin12 No prob, I didn't know it was called that either. Have seen one before though
Nice mask today :-)
Where can I get a face shield like that? Vendor?
