[@nunyabizness2620]

You get my vote for the #1 Model 3 video on the web IX - great work and thanks for sharing! Next best thing to a service manual.

[@karenrobertsdottir4101]

Whoa! "Note the size of these cables - they're huge! They're way bigger than you find in S & X. That implies that 3 is capable of a higher rate supercharge than S & X, at present. They are very big." --- That got my attention!

[@Ingineerix]

The 3 sports 95mm2 cables (3/O AWG), whereas S/X currently use only 70mm2 (2/O AWG). The enabler of the 3's higher charge current capacity is likely due to the improvements brought by the 2170 cells.

[@karenrobertsdottir4101]

So 84% more cross sectional area in the cables then. Nice! Hmm... lol, trying to look up maximum rated current for those cables, but most wire gauge/capacity charts don't go that high. ;) If it's linear scaling and the old ones were only suitable for 120kW then theoretically these would be suitable for 221kW. But that's a lot of assumptions.

[@morrisg]

No, I believe the 95mm2 spec is already an area measurement, so it is only 25/70 = 35.7% larger in cross section area. Also, we don't know the stranding specs (# of strands and each strand's AWG or metric area spec). Plus there's usually insulation temp spec which is used to derate max current. At any rate, as Ingineerix states supercharging capacity is probably set by the 2170 cells / cooling capacity of the main battery.

[@karenrobertsdottir4101]

Oh, sorry, mm², I was reading that as mm - my mind didn't parse the lack of superscript :)

[@Clark-Mills]

Is it possible that they've cut over from Cu to Al for weight/cost/availability reasons? That might explain the thickness difference?

[@karenrobertsdottir4101]

This is the sort of thing that keeps me from doing more than simple maintenance on cars. I look at that laid out there and think, "There's no way that this would ever go back together again.... or at least not "back together the way it was" ...

[@imho7250]

Did you block the cellular signal so it can’t tweet Elon and ask for an extraction mission or the code to initiate self-destruction?

[@aliabdallah102]

IMHO tbh I wouldn't be surprised if it didn't have something that'll brick the ECUs.

[@imho7250]

Ali Abdallah, yes, I think Tesla has been increasing security on its ECUs over the years and it’s why many have resorted to just making their own inverter driver for the Tesla drive units. I think jailbreaking Tesla will be a real thing once there are 1 million on the road.

[@aliabdallah102]

IMHO oh yeah. Tesla IS the apple of cars. When they find a way to legally do it. They'll make it warranty voiding to put anything but the michelins illegal. And then remotely disable the car.

[@imho7250]

Ali Abdallah, Tesla is reportedly working on a track mode which seems almost like a rooted Tesla OS, and will let people change settings which void the warranty. Elon basically eluded to this during his interview with MKHB. I’d love to have a Tesla with full overclocking unlocked and access to everything with some easy to use utilities that let you test each setting for overheating. Really I wish someone would make a DIY EV where you can buy each part just like buying parts to build a computer, where the body and chassis would be like selecting your computer case, and then you pick the motherboard which supports plug and play drive units and battery modules. Then it has some OpenEV operating system which defaults to all the recommended settings for whatever you plugged in, and then let’s you tweak them up to safe limits (and beyond). Imagine the sort of business you can have if you can build a car and keep upgrading the components as you can afford them.

[@darreno1450]

[@maxg4958]

Thanks for acknowledging a gimbal is required and coming; I appreciate it.

[@andya9268]

Can you make a video of fuse in model 3 ? How the fuse impacts the car while the airbag is deployed and how to replace them . Thanks

[@FrankThorley]

Two Questions: 1) What Frequency is used in M3 RFID Cards. 2) Fronk latch wire colors/functions. I really appreciate your M3 system and detailed component analysis & reports. Fantastic work.

[@Ingineerix]

13.56 MHz. It uses the NFC standard, you can read Tesla cards with a standard NFC reader. Explaining the detailed functions of the frunk latch system is a project in itself, sorry. That would require paid consultation.

[@ronolsberg1468]

You show the redundant power connections to the power steering rack in the video. Do you know if the power connections at the power steering rack are 12VDC, high voltage DC from the traction battery (they are red/black and not orange) or three-phase AC converted from two redundant upstream modules? If three-phase, that would require two each HV to three-phase AC inverters. I read somewhere that the power steering assist motor is three-phase AC and not 12VDC like most ICE vehicle use. Thanks for the great content and for any answers to my questions! Watched your video on the VC-Front module and you mentioned the two red wires on the right went to the PS unit. So it looks like it is indeed 12V DC. Maybe one line is feed directly from the DC-to-DC converter and the other directly from the 12V AGM battery. Not sure where the three-phase AC/inverters came from?? A possible way to verify redundant side, every time you drive the vehicle, would be to use the battery side when in reverse?

[@jw796]

Thank you. I have not yet seen the first responders cut off location, access or functionality. I know its cuts main power(@ relays?) and it's near? right windshield and hood.

[@Ingineerix]

[@johnsanchez5751]

Great walk-through video. Thank you for taking the time to film and share.

[@ericjorgensen4826]

As a tech geek I find your videos to be most interesting, and I thank you for them. I just purchased my MX Plaid on June 30, and have a question about the antennae. I believe the FM antenna is in the rear hatch glass. Can you confirm that? From this video I see the GPS is in the front 3 camera housing, and as well you point out where the WiFi antenna is located. Is the WiFi and GPS for the Model S/X in the same location? Last, do you have any idea where the antenna is located for the XM Satellite radio?

[@Ingineerix]

Wifi is in the headliner, and XM is under the glass in the rear hatch. Both are very hard to access.

[@ericjohnson2193]

This is the most incredible Model 3 video I've seen to date!

[@albert.h]

Great stuff! I'd love to hear even more of your opinions on top of calling out and identify various components and systems.

[@mzed1014]

Fascinating to see one taken apart. It is amazing that the tiny drive unit throws the mass of this car forward like a rocket. Please try and go lighter on the acronyms. Thanks.

[@taylormcclure7868]

Can you tell me what type of coax is used for the side repeater cameras? I'm working on a special project.

[@Ingineerix]

I don't know, but the camera signal is encoded with data and power on the Coax, and it's using DisplayLink III.

[@JohnSmith-rf1tx]

Great stuff. Given the architecture, it looks like it will be very easy to build these cars as a Right Hand Drive (RHD) without having to source/build many mirrored parts. Potentially very good news for those in the UK or Australia/NZ eagerly waiting for a Model 3. Pretty much only things that need to be swapped are steering column and pedals with the glovebox (and I believe the metal already has the cutouts for them on the right). Maybe a RHD power steering rack? The key card reader needs to be swapped to the other side (trivial). And so does the charger port/door, etc. Anything else with the charging hardware that would need a special RHD-type part?

[@joshualewis3337]

They won't swap the charge port (see model S & X). They'll need to swap the autopilot computer over, and maybe the brake booster. Doesn't look like they need to move the HVAC unit, unlike in most ICE cars. However it seems the windscreen glass is handed (asymmetric to get the wipers down low for aero).

[@ClockworksOfGL]

John Smith - Munro, in their tear down, said the car is basically symmetrical. So RHD should be trivial. This is a brilliantly engineered vehicle. And there’s every indication that Tesla could make a healthy profit on it.

[@yellowshuttle]

This is fantastic, and what Tesla should have done themselves. Your depth of knowledge is quite impressive. Thanks a lot!

[@Top12Boardsport]

Great job. Looked at this several times and still interesting.

Hi Phil, you have the best videos on Tesla tech, great content, as somebody commented - "only Tesla videos worth watching" , maybe you ca do a video where you talk about super-capacitors and how they might change the Tesla battery pack, you might even do a test with a big pack of super-capacitors in parallel with the tesla battery pack and see if this influences the driving. Too bad Tesla tech is not very hacker friendly.

[@chuinnim24]

Amazing video Ingineerix! Thank you so much! I've been wondering about the cabin-facing camera. Are you able to get a screenshot of its view? I'm curious about its resolution and field of view. I guess I wonder because, although Elon has apparently stated he's not into using camera to detect whether the driver is being attentive, I'd like to know if that camera could be set to that purpose with a mere software update if Elon so desired. Also, does the developer mode of your unit contain any of the beta functionality Elon tweeted pictures of in June, namely, the features such as: "Follow Nav", "Traffic Stops", etc?

[@rrrggg4334]

9:00 I heard those cables are aluminium (maybe copper clad like some cheaper audio cables?) not copper like in S and X - that's why they are thicker. (And cheaper of course).

[@danielstockwell3395]

i think Aluminium is also lighter for the same current than copper, so weight saving as well.

Hello. Do you happen to know where the pins are on the board for the pedestrian warning speaker? I have gotten tesla to turn on the features on my car, but I'm looking to add the missing harness. I suspect it is on the FSD board with th rest of the front audio outputs, but if your harness has it, this would be awesome to have confirmed. Thanks!

[@ai4px]

If you’ve still got this setup on the floor, can you point to a best place to drill a hole in the center console front to put an extra cigarette lighter plug? So it’ll clear the ductwork stack.

[@Ingineerix]

You will need to take the console apart for this, so that's my best advice. It's not that hard to remove and then you'll have full access.

[@christianchisena6615]

Hi, I want to get the positive 12v, and bring a cable in the trunk to power up an AC inverter (2000w). I tried it connecting directly in the front, getting the +12V from the battery connector where a 35mm2 positive cable arrives from the main battery in the back. I do not want to put a cable from the front to the back and I was wondering if I can connect a cable (35mm2) directly close to the battery as in the video is visible. What is the best point to get the +12v (with very high current) to get back in the trunk? Many thanks

[@sylvaing1]

Nice to meet you. I have a question The rear glass heating wire 12V power does not come on. What should I repair? There is no abnormality

Aren't the charge port cables larger because they are aluminum instead of copper like the S&X?

[@WICKED9994]

good question

[@Ingineerix]

This is definitely a possibility, Unfortunately I can't answer this question for sure without cutting into this cable. Let me do some more research.

[@karenrobertsdottir4101]

If you don't want to cut them, and can disconnect them fully, you can measure their specific gravity with a water test. That'd give you the average of the cables/connectors/insulation combined, but there would be big differences between alumium and copper. I do this for minerals: www DOTT johnbetts-fineminerals.com SLASH jhbnyc SLASH articles SLASH specific_gravity.htm You'd just have to scale it up.

[@David-mg8fd]

Or you could just measure the resistance...

[@michie9933]

Is there no thermal isolation at the heating/cooling system? Should be inefficient when you turn on the heating during winter period

[@Ingineerix]

The cabin is exclusively heated by a PTC electric resistance heater, it is 100% isolated from the gycol cooling loop. Only the A/C system is shared, for cooling only.

[@pierrechampoux7566]

I was thinking that the battery is heated using this system so if heat is lost by not isolating the plastic tube, it becomes very hard to keep the battery warm enough while driving and being stationary in cold weather. Same for the battery underside.

[@tomekstanek]

[@vico5980]

That huge charge cable, leading to the charge port, could well be an aluminum cable and needs that larger dimension to have the same cable resistance as the copper S/X cable. Just a guess. But it could be both, an aluminum charge cable and a design that will support higher charge rates in the future.

[@Ingineerix]

Yes, this has already been determined.

[@Naked-clean]

Have you made a video or comments as to: 1) Where the EDR connector is located? 2) What is the type of connector used to access data? I am in the process of preparing to download crash data in order to refute the other driver's claim.

I'm not aware of a dedicated EDR connector. The RCM is made by Bosch and has an internal EEPROM for storing the EDR, so I'm sure there is a way to connect directly to the RCM for retrieval.

Very nice, what protocol is used between the ECU and the motor inverter? Is it CAN bus, if so could a CAN repeater be used to adjust the messages? for instance, adjust throttle up by 10% for whatever the input? This would be warranty voiding and track only mode. Basically a man in the middle hack.

[@morrisg]

ECU and motor inverter are on the same board. See the inverter board video. I assume the CAN messages to the inverter board are only simple things like go pedal position and Drive or Reverse.

[@Ingineerix]

AutoxMx5 is correct, and on the RWD car there is no CAN signalling involved, the go pedal is wired right into the inverter. No performance hacking without a complete inverter software re-write, and I doubt you can do better than Tesla without buckets of blown inverters.

[@Top12Boardsport]

So impressed. Great job. Assembly and disassembly would be nice also.

[@johnp.weiksnar6861]

Whoa, at 6:11 you can see the passenger side B-pillar guts is just missing the NFC antenna and connector (clearly for eventual RHD exports). I wonder if the domestic version could be upgraded to allow card access on the passenger side . . . likely never that simple. Thoughts?

[@Ingineerix]

I would imagine on RHD, they just swap the modules. I'm not sure why you would want NFC on the passenger side. If you don't want to use your phone, Tesla is coming out with a fob accessory soon. (Will not need to be held to the B-pillar.)

[@pierrechampoux7566]

For Track action, can you suggest a way to disengage traction and stability control and keeping ABS?

[@Ingineerix]

There is an internal mode for testing, but not available to normal end-users. It would require CAN injection and will likely void your warranty. Best bet if you are that serious about tracking a Model 3 is to buy a P3D and Tesla gives you the track mode setting right on the UI.

Amazing stuff! But what about speakers, tire pressure sensors, head lights and tail lights, airbags, seat heaters, door electronics/window lifters? And how do you test all this stuff, when it is not in the car? I mean: all your sensors (wheel speed, tire pressure, brakeline pressures, acceleration, GPS, coolant temperatures, cameras, radar, ultrasonic sensors, ...) do not send values/data that match anything, that is expected by the matching electronic control unit. The layout may help you in tracing soingles.

How do you get access to the linux on the ICE? Do they have a serial console exposed ?! :D my new car (not a tesla) is arriving next month, it runs linux (automotive grade linux) on the center console as well, and i want to have root access to display some more information :) I guess they use the CPUs security features to only load a signed bootloader and the bootloader checks the signature on the image + afterwards the kernel uses dm-verity to check for modified flash blocks.. So modifying the image on the emmc is probably not possible without breaking the chain of trust..

Bingo. Your assumption is 100% correct.

[@jonathanterranova448]

? Are there any settings that would allow Tesla to turn-on automatically (plugged-in or not) and warm battery pack.... say if temperatures got below said temp. or -10 degrees c/f k 🤔😐

[@Ingineerix]

Tesla doesn't turn on pack heating, but when you go to charge the pack, it uses power from the grid to heat the pack above 0C before charging. The only other time pack heating is routinely used is when navigating to a supercharger, the pack will use some energy to preheat itself to allow faster charging.

Silicon Carbide is being mainly deployed to MOSFETs at 650V and 1200V. SiC IGBTs aren't really a thing.

[@stevebakker6884]

Great work! Finally a teardown that names names. Interesting that the inverter is running MOSFETs. Given that Elon Musk used the term Silicon carbide inverter, it would seem that these are silicon carbide based MOSFETs. In an article that I posted speculating on this topic, someone apparently-in-the-know asserted in the comments it was likely SC MOSFETs. Now we know. Now looking forward to seeing your teardown of the motor (stripped to core teardown) to see if it is a "vanilla" IPM reluctance machine, or if there is some Tesla magic in there... such as permanent magnets embedded in the stator. Thank you for the videos!

[@danielstockwell3395]

is it not the Performance model that has the higher spec Inverter? The standard and AWD has one optimised for cost etc

[@stevebakker6884]

According to what Musk said, it is the same inverter for all cars. Tesla just culls the inverters that test for "highest sigma output" and installs that subset to the P cars.

[@ClockworksOfGL]

Steve bakker - IIRC, there are PMs embedded in the stator. He does a demonstration in another video that shows heavy cogging when the rotor is turned by hand. My big question is the composition of the magnets. I read a research paper awhile back that stated one of the theoretical advantages of this motor design was the PMs did NOT need to be particularly high performance. Rare earths wouldn’t be necessary. So I think there’s no rare earth magnets in the motor of the model 3.

[@stevebakker6884]

Hi Bryan. The cogging he demonstrated may well have been from the PMs in the ROTOR. I've seen a motor taken a part and the M3 motor is at least in part an IPM (Internal Permanent Magnet) motor. And they are likely rare earths, because someone also published an agreement between Tesla and a Chinese supplier for rare earths. If there are also PMs in the STATOR then Tesla would be following some more recent research that may set Tesla's IPM motor in the 3 apart from the many other automakers also using IPM motors. If you read the piece I posted on the topic it will refer to a companion piece, and together all the info and links I am referring to are there.

Yes! I was hired to consult and do integration engineering on this demonstration project for just such a thing: www.thedrive.com/news/31732/austrian-engineers-transplant-gasoline-engine-into-tesla-model-3-to-create-full-hybrid

[@nick0780]

Wow! Thanks for doing this.

[@S3XYcars]

i want to fix a model 3 which are very injured...have you got a ling for spare parts please (i'm in France)

[@Ingineerix]

We sell parts on Ebay

[@WANDERER0070]

Very interesting,,thnx for showing all these details, Any idea how much $$ the battery alone cost?in case one needed to replace it..

[@realvanman1]

I'm seeing the makings of one hell of a go cart here... ;)

[@fredhamilton1701]

Also, doesn't KZbin have a video stabilization option? Not as good as a gimble but you could run it on all your existing videos.

[@Ingineerix]

It doesn't help with fast pans. Only higher frequency vibrations, and it doesn't work that well.

This is so beyond amazing, an excellent job, nice idea using the honda radiator. Such a cool setup to have. Just wow. Maybe I missed it, but do you have the air conditioner hooked up? What a beautifully engineered vehicle. The future of cars looks amazing.

[@Ingineerix]

I did have it hooked up, but to get the HVAC box out, I had to recover the refrigerant. (Amazingly it survived the crash!)

First off, love the breakdown! Awesome work. Quick question, looking to add heating elements to the steering wheel. The purple connector under the steering wheel airbag, only has 3 wires, but looks to have 6+ pins on the female side. Are those terminated through the steering control module that you know of?

[@Ingineerix]

Sorry, no idea on that Sean!

[@wtlarsen1]

Do you know how the parking brake works? What physically happens when you put the car in P? and what is the additional small clunking noise if you then hold down the P button to get the parking brake indicator to appear?

[@Ingineerix]

There are electric motors on each of the rear brake calipers that can mechanically apply the rear brakes when you engage P. If it's already applied, the second push-hold just tries to tighten it, but nothing will happen except a small noise.

That’s gonna be one heck of a sand box cart when you put it together

[@rogermoiny2827]

Very nice video, are there 4 speakers at the most rearward part of the dash that would touch the windshield?

[@Ingineerix]

3 full-range speakers on the dash and 1 tweeter in the middle.

[@tombodera3338]

Awesome video. Great job. Keep up the great tech videos for model 3. shake cam was fine. thanks.

Okay so pardon me for not reading all 280 comments. For a P3D+ what do you think it would take to improve cooling to maintain max power all day at the track? I imagine something in the frunk that adds coolant and more radiators but maybe due to the low temperatures of the battery packs vs ICE vehicles a bigger condenser or 2nd condenser is more realistic.

[@Ingineerix]

Research would be needed. It's not a trivial problem.
