4 Stall Megacharger Installed in Sacramento

[Mrbrock]

Is that 8 cabinets for the four stalls? Funny how one stall in the video is ICEd

Yes, here is an overhead shot of the Frito Lay Modesto Megacharger. The sat view of Pepsi shows construction.

Here’s the permit from Pepsi Sacramento. Note the price. And are 750kw posts really “Megachargers”? Assuming mega means MW? Or is this like FSD…?

 

[TSemi]

Assuming mega means MW?

Yes, the m in MW does mean mega. It seems you think a Megacharger MUST deliver mega kilowatts or it's not considered a Megacharger. DOH! It can but doesn't necessarily mean it MUST! DOH!

Unnecessary answer. Please stop and read what I wrote. I asked about the mega in megacharger meaning megawatt. Not the m in mw meaning mega.

And you seem to believe that FSD doesn’t mean the car is fully self driving. So why would a megacharger actually provide Megawatt charging? By your definition, any supercharger site with more than a MW of potential output should be classified as a Megacharger.

And in this specific case, those charging posts literally cannot deliver 1MW or more. They are 750kw posts. Not 1mw posts being fed by 750kw cabinets or some other rate limiting factor. The posts themselves are the rate limiter.

I am not surprised by the naming, it goes with Tesla promising something in a name that it hasn’t actually delivered.

If that is the full cost of the system with installation that is a good price

Why do you say the posts cannot deliver 1MW?
There are 8 cabinets and one older revision megapack.
With all 8 cabinets at full AC power and all four pedestals in use, each pedestal gets around 2x 350kW = 700kW.
However, with cross linked DC bus (potentially linked to mega pack) and less than 4 stalls in use, those paired cabinets can put out 1MW+.
However, one would not specify the system as 4x1MW.

i'm pretty upset my 250 GB harddrive doesn't actually hold 250 GB. stupid Microsoft. time to short them...

seriously?

Wrong forum.

Dude, sarcasm, 250GB shows up as 240ish in windows. Hes saying 1mw being 750kw in actuality is the same.

Um, the permit very clearly and specifically says 4 750kw posts. What you are gueesting means that a 250kw V3 post can actually deliver 33% more than it is rated, or 330kw+. The posts are not limited to 750kw by the cabinets and DC bus but by the actual posts themselves. The internal cables and componentry are only rated at 750kw.

Unless Tesla is making two versions of Semi charging posts, these are the same as ones in Sparks that are fed by 4 cabinets each.
Report: Tesla Installs First Megachargers For Semi At Giga Nevada
V3 cabinet outputs are limited to 250kW each. Semi posts (most likely) link multiple outputs together. 8 outputs linked is 2MW (or the cabinets' input power limit).

Because charging is separate from loading and unloading activities. Putting a charger at the loading dock would mean that dock should be reserved for EV use. Putting the charger in a separate location means an EV truck can drop a trailer off at any dock space, charge, then pick up a trailer from somewhere else. It's rare for a fleet truck driver (such as Pepsico) to pull up to a dock with a trailer, wait for it to get unloaded, then leave with that same trailer. They drop a trailer, then grab a different one and hit the road again.

This is all correct plus , and I suspect the huge issue, is that loading bays are dangerous places, this is where things break and people get hurt. Not the place for a spare 1000 volts sitting around for a driver to back into them or a forklift operator to hit them, etc etc.

Tesla Semi production specs: powertrain, battery, Megacharger output, and more

A visit to PepsiCo's Frito Lay facility in Modesto, California provided some details that otherwise reveal the Tesla Semi production specs.

www.teslarati.com

MEGACHARGER OUTPUT​

The Tesla Semi features a charging port that’s different from all the vehicles that the company has released so far. The motoring publication noted that the Tesla Semi’s Megachargers installed on the Modesto facility could provide around 750 kW of power, or about three times the output of the company’s Supercharger V3 network.

The cables for the Tesla Semi’s Megachargers are thick, though they are reportedly easy to manage compared to some DC fast charging networks in the market. Charging the Semi from almost empty to 70% typically takes about 30 minutes. A full charge all the way to 100% reportedly takes around 90 minutes.

These trucks still look like they're a lot of fun! I wonder if Tesla could make cement trucks?

 

[ThomasD]

With 10 cubic yards of concrete the average Cement truck weighs around 60 to 70 thousand pounds. Ready Mix Trucks burn around 4 gallons of fuel an hour. As long as you can charge them fast and keep them rolling it may work with an electric Cement Mixer Semi. Charging to just 80% will most likely not be enough. The foreman on the job may not have time for the Trucks to take 30 or more minutes to charge. Continuous running of 400 loads for 18 Hours on this job.

Totally useless post. Just happen to be next to the Pepsi facility looking at rocks.

Carry on.

Electric cement trucks are possible. More will be coming soon.

The Tesla truck isn’t really built for this chassis wise but they could make necessary adjustments.
