Powered Frunk In Action! Great shots!!

[JBee]

Yeah, I have exactly THREE tools in my shop that use 220. The table saw (had to reconfigure it), the dust collector, and the spindle on my CNC.

all of them are BIG and STATIONARY..... they don't leave the shop.

What job site tools use 220? A welder?

All my non-battery power tools are 230V.
1400W 110V are just boys toys.

In 'stralia we don't do half measures, here a real home table saw is 3phase 400V.

There's a light in there. That would be 12V, but you'd have time keep the trunk switch open so that it runs when the frunk is closed. The 12V battery is right behind frunk backwash though, so nothing a small hole and cable can't fix.

People are talking like the truck has a 12v battery, but I thought it was already confirmed that the electrical system would be 48v to save on wire size and weight.

I suppose you could use a converter like this one below to get 12v, but who knows what that will do to the 48v electrical system? Not knowing how it is designed, hooking up such a large electrical load to the 48v system could have some negative consequences....

But is there a 12v battery?

Yes. I doubt there will be a 48V battery, it will just be a buck converter from the main pack. They need 12V for the compute module and cameras to run when the druvetrain is off

You would think with that dash being so large they could grant more frunk space..

Actually, you might think that but I will think that Tesla did an amazing job packaging the truck within the external and internal sizing constraints they had.

Think I will have a better chance at fitting my golf bag in the CT frunk vs my Lightning. My full bag does not come close to fitting in it. CT may not be deep bit looks considerably wider the Lightning.

Before anyone goes off I most likely will not be putting my clubs in the frunk and it does not matter to me. Just using as a comparison with Lightning. Lightning volume is great, but it is narrow.

There's a thread we're we went through the patent. It's a new connectorless 4 core bus system with remote processing units, and that gets rid of most if the wiring length, not just the 48V. Each processing unit would then have a buck converter, or mini inverter motor controller, depending on what was powered. CPU/GPU needs low voltage, (under 2V) and most mainboard power supplies are 12V.

PS you'd need three of those converters you linked to just to run the computer.

It's the result of shortening the front end for the "it must fit in my garage" crowd.

it’s really not, in a way

the front end is just as short as the Lightning from say, tip of bumper to front axel line. It’s also ~identical to the Lightning from tip of front bumper to dashboard.

the difference in Frunk depth then isn’t in front of the axel line, it’s instead the available space *behind* the Frunk, towards the cabin, and forward of the dashboard. Below been proportionately adjusted to assume CT is ~227”

and so while in theory, of course, they could have stuck a long nose out ahead of the tires - and had a nose longer than the lightning - but it’s not clear they didn’t avoid that that primarily for crashworthiness/visibility (see eg the Lightning) etc, not for reasons of overall length.

afterall, the lightning is 232” where the CT is 227” … that’s only a 5” delta, AFTER they took 6” off the CT’s original prototype bed length (from a 6.5’ bed to a 6’ bed).

Though the CT manages to still have 6” more bed length, and ~5” less overall vehicle length, which means the CT somewhere loses roughly 11” of total length between front bumper to rear of cab compared to Lightning.

And it’s not between front bumper to dashboard.

Because the CT is just as short as the Lightning from bumper tip to dashboard, that results in there being in theory roughly 11” less length between the dashboard and rear bumper, including and despite the CT bed being 6” longer

the CT has three voltage buckets.

where an eg Model S has two, eg a “low voltage” (12v) and “high voltage” (eg pack), the CT has 3:

• low voltage (12v)
• mid voltage (48) and
• high voltage (pack)

I think it's odd that the person taking the video failed to get it actually closing.

Do people really have this much trouble operating the video mode of their cellphone?

My theory is it was a rapid burst of photos stitched together to make a video. Like they had the camera on the wrong setting and couldn’t switch it to video in time.

And 5v for CPUs
3v for LEDs
20v USB-C outlets...

If the CyberTruck even goes with the 48v system there will likely be many different buses for all kinds of power demands. 48v for everything may make sense someday, it's probably foolish for Tesla to try to ramp up suppliers to 48v EVERY component, at volume, in the truck before November 30th.

This paper appears to be legal 8.5x14

puts Frunk void height at ~16” and depth at floor centerline at 18”

Puts CT Frunk volume at roughly the following footprint, but a ~bit more dramatic height slope forward from the max height at back wall:

or as gone over (to death) before:

about 1/2 to 3/5th the volume of a Lightning Frunk, but the preferred usability of either depending on the need (eg since the shapes are different, they’ll fit different things differently)

The Cybertruck branding on the wall is dope

I kind of know where most regulars here are coming from, what directions they are going to go with a post and why.

Your posts are a mystery to me.

Well done.

RV. Imagine going camping and no having to listen (or smell) your nieghbor's generator.
