And yes, charging cable for CT is same as Semi and therefore, access, baby access.
I doubt the Semi has the same connector as the CT. All of the CTs I've seen used the NACS port, while the Semi's were always shown with a much larger connector. Maybe the Semi will have more than 1 port, but the CT will have only a NACS port for sure.

This is a paradigm shift in vehicle charging. Charging from 0 to 100% in 10 minutes is a game changer. Tesla just raised the bar.
Please let's not start throwing out BS speculation about charge times. Nothing has been stated and there is no indication of what the charge curve looks like.

I was skeptical about the clutch system for disengaging the front motors. Letting the motors spin freely should have zero impact on efficiency, other than the negligible drag of friction on the gears and bearings.

However, friction leads to heat, and heat is death for the Tesla electric motors since it destroys the magnets. If they let the front motors spin, they would need thermal management as well. (This is why a Tesla should never be flat-towed.)

So, friction losses PLUS cooling losses EQUALS use a clutch. Gotcha.
No, that's not how it works. The disengagement is so that coasting motors don't induce eddy currents, which will cause resistance on the drive axels. Has nothing to do with friction. The motors are essentially frictionless.

Cory Steuben (Monroe Assoc) had some very interesting takes in the excellent Farzad Mesbahi Semi Delivery live event re the Ver 4 Charger and other relevant aspects of this important "new" CT information. It starts at 2:48.20 of the over 3 hour event coverage.

Please don't rain on my parade. I'm on cloud 9 and not just from Denver Rocky Mountain High Premium. :p

Actually what I'm really hyper excited is the very real 500-mile range on full load.

I'll now be watching it's performance in freezing weather and uphill like the brutal Donner Summit.

After hearing and reading about the disappointments on F150 Lightning, as I said before, Semi could mirror CT's capabilities and there is much more reason to hope that Cybertruck will be a ton better.

There is also the oil pump that has to run if the wheels are turning.
And in truth; while nothing is "frictionless" in this/our universe, we can all agree these drive trains are pretty low for obvious reasons.

The voltage and current, i.e., power, available to charge the battery is just one/two factor(s) in being able to do 'fast' charging.
Other important factors, that is, limitations, are the heat generated during charging (heat can be a battery killer), and the so-called plating effect that can damage the anode (see: https://www.machinedesign.com/mater...one-reason-fast-charging-damages-li-batteries ).
On-board charging intelligence (usually in the vehicle) controls the charging rate to avoid over-heating and battery damage by limiting the power delivered to the battery based on what is considered optimum for safety and battery longevity.
Assuming these, and perhaps other factors can be overcome in battery control and design and perhaps chemistry, "super-fast" charging could be a reality.
However, I have always thought that battery swapping is a simple, no-brainer solution - just swap out a depleted battery for a fully charged one.
There is already at least one company in China and Norway that has developed a system that can do that quickly (see: https://thedriven.io/2022/11/08/ev-battery-swap-technology-continues-to-race-ahead-in-2022/ )
"... Nio’s EVs are designed to have battery swaps and the whole process can be done in under 7 minutes... To date, the company has provided over 14 million battery swap services and currently averages 30,000 battery swaps a day according to their social media posts. ..."
Besides the time for charging problem, the Nio solution would eliminate the EV owner's eventual problem of loss of capacity of the vehicle's battery, eh?

Any better minds get a crack on energy usage between Kettleman City (253' elevation) to Grapevine/Frazier Park (4,136') on a distance of about 107 miles?

My CT will be humping the 7,200' Donner Summit in all seasons pulling an RV or carrying a truck camper, hence, my interest on the subject.

Monroe Live did an episode on the various charging connectors being used for charging EVs.
The various 220 connectors for dryers are not designed to handle the continuous load for charging an EV. Some of theses connector have melted and caused fires.
So be careful!

Old news, there's another thread on it. This isn't a problem with all receps, just the junk ones.
