Cybertruck 1000V Architecture + V4 Supercharging Confirmed!! ⚡️ "It's Going to be Used for Cybertruck Too" - Elon Musk

[Ogre]

@Dids @Crissa new video from The Limiting Factor released 30 minutes ago:



Confirming my priors here, Jordan see's a peak 612kW on a 168kWh Cybertruck - with 700kW if CT has 200kWh pack. Really simple C-Rate limitations for battery longevity. We will not see 1MW charging on the CT.

Sounds about right. So what we can expect from the various packs.

300 mile range pack (Estimated 125 kWH and efficiency of ~2.5 miles/ kW)
Roughly 400-450 kW or 1100 Miles per hour peak charging speed.
From 0% charge, the first 10 minutes of charging should add about 150-180 miles range.

500 mile pack (Est 200 kWh with efficiency of 2.4 miles/ kW)
Roughly 700 kW or 1600 Miles per hour peak charging speed.
From 0% charge, the first 10 minutes of charging should add about 250-270 miles range.


The Cybertruck with the 500 mile pack is going to be the absolute king of road tripping. Not just the best truck, but better than any shipping vehicle at launch. Almost every stop will last no longer than biological necessity. Amount of charge restored should be enough to get you to the next bathroom stop (Or likely, further).

I think your calculations are prob spot on regarding possible efficiency or just a little high in real world scenarios.

But unless they retrofit existing superchargers to provide these V4 charging speeds, charging up a CT will be painfully slow. Or they change the charging curve for CT to hold 250kw longer or unlock higher KW out of their current V3 chargers.
We only have 6 more months of waiting until new details comes out.

Awesome, I’ll check it out now.
Thank you Ogre.
Hope everyone had a wonderful Christmas!

The 500 mile Cybertruck will still be the king of charging speed on a v3 Charger.

Take a look at this highly accurate and detailed charging curve model I made in Linea in 2 minutes comparing the Model Y (green) versus a 500 mile Cybertruck. The Model Y will start charging at 250kW, but charge rate starts to drop fairly soon. The Cybertruck (blue) w/ 500 miles range is capped at 250 kW charge speed, but it will be able to maintain that rate through the whole 250 miles of charging because it never hits the 50% state of charge where charging speeds really start to slow down.

Obviously if you are charging that Cybertruck to 80% it will slow down as well, but in that case you are stopping less often. Either way it’s going to win any road trip race even on v3 chargers.

We will not see 1MW charging on the CT.

...one quibble: We'll need the megawatt charger to do that, though. Gotta have the headroom on the charger side.

A couple thoughts here.

The chargers they installed on Pepsi’s premises are 750 kW chargers, not 1,000 kW chargers.

There is a solid chance most v4 chargers won’t be 1,000 kW chargers either. It’s likely the only way you get 1,000 kW charging is by going to a truck stop designed for the Semi. A 500 kW Supercharger would only marginally slow the Cybertruck LR charging and not slow the Cybertruck SR charging at all.

Another possibility, individual chargers can go up to 1,000 kW but each 4 chargers are limited to 2,000 kW combined output (Or less total output even!).

Either way I think we’ll see sky high average charge sessions, likely be a difference between charging for 12 minutes or charging for 14 minutes.

Anyone know what the drag coefficient is for the Cybertruck?
I see that Tesla saw fit to make the semi more aerodynamic - will the wedge shape of the front of the Cybertruck perform well?

For range and efficiency, it really matters. Think jet plane.
Ford Lightning, Chevy Silverado EV, even Rivian are all making essentially big boxes that the state of the art EV technology has to try to push down the road, hence big batteries, long charging times and mediocre range.

Obviously an EV truck can't be as efficient as say the Aptera (see link) but if designers would focus on the aerodynamics, they could extend range quite a bit, probably a lot.



Fast charging infrastructure is gonna cost a lot of $$ and require beefing up of the energy production capabilities of utilities, not to mention congestion at the charging stations when millions of people are lining up to get recharged.

Why not make more efficient vehicles to begin with?

Instead of a stainless steel body why not a lightweight composite materials.
Instead of a heavy box, why not a streamlined body?
Batteries could be smaller reducing the price, weight and charging requirements including charging time per mile of range.

Go figure.

You do realize that Tesla’s track record on efficiency is the best in the industry right?

It’s central to almost every design they’ve made.

For range and efficiency, it really matters. Think jet plane.

Instead of a stainless steel body why not a lightweight composite materials.

Because it’s hard to toss bales of hay or 3 bikes into the back of a jet plane?

Aptera is a neat rig, but it’s not a truck by any means. You can’t do the Aptera thing and make a truck.

Tesla always spends a lot of time and energy on efficiency, it saves them from buying lots of batteries.

Mmmm. Headroom.

This all assumes that the high nickel cathode chemistry is identical to the other 4680. Which is dumb because if it was why would you make it?

Provided they actually make the 500 mile version ...

Elon said Cybertruck Cd could be as low as .30 with "extreme effort", so I guess it will probably end up being a bit higher like .32 or so.

 

[Ogre]

But not 3 bikes.

Or more than 1 bale of hay. And if toss a bale of hay into your Aptera, it will be there with you forever.

 

[Ogre]

This is silly.

You might just add: “Provided they make any at all!”

People need to stop buying into the nonsense the haters are bandying about. Nobody says “Provided the Silverado actually has 400 miles range…” Nobody says “Provided Rivian cancels their MaxPack battery”… though Rivian did make a big change with that.

Just stop. It’s annoying and pointless.

 

[Crissa]

And if toss a bale of hay into your Aptera, it will be there with you forever.

That's what those green 'yard' tarps with the rope edging is for. You pull the tarp closed like a bag.

I brought home a bunch of bagged garden soil and manure in the M3 during the first spring without the truck. It was a mild annoyance, and some cleaning was involved afterward. I will NOT be bringing home any of the cheaper, unbagged manure in it! We can fit one light road bike in it. A small e-bike may be possible, but annoying at best. I don't think my e-bike would go in without tools to disassemble parts.

Hay makes me sneeze my head off, it's not going into any car I'm going to be near.

If I had a truck, I would not have spent nearly $2k to get this all rigged up.
