48v Battery for Cybertruck!

[cvalue13]

Nope. Drawing a straight line from our point of view the the long rectangular object in the wiring diagram, the object is either on the point of the top of the vehicle, or in front of the driver. The camera/rear view mirror that you are highlighting is a foot or two down the glass. The driver when seated can not see the "peak" of the vehicle.

Actually, if you look at the zoomed in version Paradox just posted, it's explicit that this piece of electronics is in the dash in front of the driver, whatever it is.

I can close one eye and see just how you see it.

And if I do, I believe the smaller red item forward of the larger red item, is lined up and on the same angle. Which if so, would suggest it’s not the windshield cameras, but instead something on the dash in front of the driver?

And if-so if-so, would be consisted with HUD?

But given the good catch by @Paradox above regarding the graphic’s location of the wiper, I suppose it’s a reminder that nothing directly suggests this is an accurate reflection of the current vehicle. And indeed it also appears to show a full length tail light bar (not apparent on investor day unit), or no apparent kit for adjustable suspension (which appears to be on the investor day unit).

Could instead be a prior iteration where a driver display (or HUD) was in the mix.

Thanks for the clarifications and edu-mu-cations!

The bottom line? 6-more months of waiting until production starts

That's okay, we are coming down the home stretch. We are seeing real progress. Imagine if the pandemic had not happened.

Here is the Model 3 image for comparison.

I like like speculating, but I would be that these drawings don't represent every electrical thing in the car, as it would turn into a cluttered mess. Also, the model 3 doesn't seem to have a center screen?

I was very happy when I saw this image during the presentation. Things confirmed or hinted:

- Rear display confirmed (also confirmed via interior pictures)
- Brake and/or steer by wire and/or air suspension confirmed (see red module at each wheel)

Also, why are there 3 red modules by the tailgate? One for safety sensors, one for trailer hitch, and one for??? Makes me think there is something interesting going on at the rear.

wat 48v means?

Smaller gauge, more efficient wiring
I’m extremely suspect of their “lifetime” battery statement and id guess that replacements would be north of $1000

I really hope there isn't a 48V battery. There's already a huge traction battery and voltage regulators can easily drop the voltage to 48V. What purpose would a separate battery serve?

To run the starter motor! How else do you expect to get ignition? LOL.

There is always something interesting going on at the rear. We are genetically programmed to be interested in whatever is going on at the rear.

Musk says it’s a 4x reduction in copper. Big deal.

This has been discussed ad nauseam on these electric cars (ie. not just Tesla) for over a decade.. They don't want to keep the high-voltage battery contacts open continuously.

Google search: why is there a 12v battery in an electric car
https://www.google.com/search?q=why+is+there+a+12v+battery+in+an+electric+car

It's more that batteries have a secret weapon: They don't care how many amps you draw. Especially lithium batteries. As long as you're inside their temperature range, they don't care.

DC-DC boards, on the other hand do care. Alot. They're super-inefficient outside a narrow range. It's best to have them sized exactly for the job and no larger (and they can't be smaller) and turn them off when you don't need them sucking power doing nothing.

So you use the DC-DC to charge a battery, and then use that battery for the long tail and peaks.

They don't want to keep the high-voltage battery contacts open closed continuously.

Fixed it for you.

Something I just noticed in this image: Is that the windshield wiper mounted at the center base of the windshield? I guess at one point it was a consideration?

It could be the electromagnetic wiper from the patent application?
Maybe the BAW is just a place holder?

 

[Kahpernicus]

Probably just a save point in the modeling when they wanted to pull assets for the wiring diagram.

Re-watched the bit about 48v wiring and it’s much bigger than just the difference between wire sizes and voltage. They are replacing the entire wiring harness with a network and delivering the whole system of power and data in one wire. Each local controller talks to the network.

Huge change beyond just wire size. Wiring harnesses are expensive, difficult to install, hard to change, and difficult to troubleshoot. Their new ethernet based setup can be installed by robots, can be changed just by attaching a new endpoint, and they can plug into any part of the car and see where a problem is (essentially). Hopefully they open this up to hacking because the potential is massive.

Why isn't there a Thumbs Down and an Informative and Helpful button on this board? Just hitting Like for everything seems unhelpful and Amazing Sad and Angry isn't useful to anyone

The thing going on at the rear of the CT is probably the 240v inverter output or the compressor plug

Will be interested to see if they include a 12v output that is powerful enough to drive a winch, maybe jumpstart another car. Lots of 12v accessories out there they'll need to make custom CT 48v versions of.

Likely same reason the media button which gets used a bunch is buried under a drop down while the ability to change font sizes is an icon in the editor. The admins set up the forum software and kept the defaults.

@Administrator I don’t suppose you could add an “Informative” icon to the reaction emojis and maybe move the media embed into the main editor bar?
