You won't find ANY right now, and probably not for a long while either. Tesla just (like last month) opened their first 250kW charger but obviously that is only for Tesla's

The biggest problem for EV's is the grid being able to handle chargers that are big enough to charge cars in the time it takes to fill up with gas. Current "fast" chargers are already causing problems...hook 4 of those 250kW chargers together and you potentially have 1 MW of random peaking? No freaking way with the current infrastructure, and demand charges alone would render them a financial dumpster fire.

There is a lot of work to do, way beyond the automobile tech needed, to get EV's where they need to be.

[RWebb]

Porsche swears they will scatter 250 AND 350 kW chargers all over the landscape, but yes, for now it'll be slower charging only.

you are talking 'bout local grids, right?

[biosurfer1]

I'm talking about most electric utility grids. Most are in dire need of upgrading, and just about none were built with huge peaking loads in mind when they were designed.

If a customer would come to the utility and say "I need service and expect a typical load of 1 MW" that would require a lot of prep and a ton of money depending on where they wanted to be located. Add to that this particular "customer" (EV chargers) have completely random load curves going from near 0 to 100% at a moments notice with no schedule? We would be talking major, MAJOR upgrades needed to infrastructure and even then, they would be subject to the same demand charges like any other customer, costing $1000's a month to just be ready to serve, and would never pencil out with the very few Taycan's that could be in the area.

[RWebb]

people talk about "the grid" but there are really 3 grids serving the US and Canada - they are inter-tied

- not sure what you mean re grid

some studies saying local grids need upgrading for high EV use my guess is that means substn and its distributaries - is that what you mean?

250kw at 800 volts!
Lol
I've played with those 150kw genies, but that's a whole different game. I don't think anything commercial goes up to that high voltage?

[Grog]

The grid is relay protected for under & over voltage, over & under current, over & under frequency & instantaneous current. The "grid" would hardly notice a change of 1MW. The grid can take 1000mw plant instantly tripping off line, frequency drops just a little, but the plants that are operating in what is called spinning reserve will pick up the load. The relay protections are for the power lines to prevent them from being over loaded, mainly from a short caused by tree branches, cars hitting power poles, downed lines etc. If 1mw of charging stations are connected to the lines to a sub station and on to the grid, the system is designed to take the load, or it wouldn't be there.

a common voltage for equipment at my plant is 4,160V. Our feed pumps, 3.7MW to run. Our plant output is around 600Mw @ 230Kv.

I've seen welders in Germany that were ~700 Volts 3 phase.

I also work for an electric utility.

As a matter of fact, once EV's are the norm, the grid will be more stable since any plugged in EV can provide power back to the grid if needed vs draw from grid.

A couple of questions.

Are the neighborhood grids capable of handling half the cars in a neighborhood being electric? Will upgrades be needed?

Will losing part of your charge back into the grid be accepted by owners? I expect my vehicle to be fully charged in fhe morning for an out of town trip but find it at half or three fourths capacity because power was redirected back into the grid. I wouldn't be a hapoy camper.

I might be misunderstanding.

[David]

Your home charger won't be 250kW since you have 8 hours or more to recharge. My home is so much more efficient now than when it was built 40 years ago that the extra 7kW for normal charging wouldn't be a problem.

When cars and the grid are smart enough to know when is a good time to charge and when to discharge, they will also be smart enough to look at your calendar and know if you have a 40 mile commute or a 300 mile road trip. You could also tell the car not to discharge more than x amount of power.

We have a large battery plant for load stabilization out in West Texas near the wind farms. It's constantly charging and discharging. When it discharges it's for seconds at a time or less so we're not talking about cars selling large amounts to the grid but rather smoothing the load when a large load comes on until a slower gas plant can catch the load. Unless you want to sell more to the grid perhaps when there's a spike in electric rates and your car would smart enough to do that or any number of other charging and discharging scenarios.

"48-volt anti-roll bars"

What??

Yes, the distribution network is what will need upgrading (at least around here). The transmission network will be fine but the local transformers and substations can handle chargers here and there, like are currently being installed, but start to try any install 100's of 150/250/450kW chargers and there will be a BIG problem.

I do know that Porsche has electrically engagable/disengagable anti-roll bars for the Cayenne. Nice for uneven/offroad conditions.

operative word "can"

I expect most people would not be ok with this as charge times are already painfully slow.

Also, how will an onslaught of electric cars not drive electricity prices way up for everyone? Not just due to supply and demand but because all sorts of new tax hooks will likely come along. And then there's the cost increase for electrical infrastructure.

Considering the tax... take away gas tax (~70 ¢/gal in this State) and I expect straight Plug-in's would not compete economically with any of the hybrids and many of the gas sippers; say, Honda Civics.

Wait, what am I talking about... this thread is about a $140,000 electric car. Who cares about costs.

[island911]

Styling. What happened to the Mission E look? That was nice. Clean.

This Taycan... uhm... O'Tay...

Not destine to be a classic, that's for sure.

[svandamme]

My biggest annoyance is that they build a huge battle ship as their first EV and not a sports EV like the Tesla Roadster.

the 5 seater is way to big, that back seat, interior and doors are all extra weight that needs to be hauled around and most of the times you'll see the Taycan driving, you'll see it with 1 driver, and maybe if you are lucky , on a good day 1 pax.

Germany has such better infrastructure, let alone electrical code.
America... Eh just wire nut the connections!!

My well pump is ran off 480 volt three phase gen set. finding a relative low kw (30)unit was a pita. It's just not common when you can transformer and vfd everything.

I dunno. I just don't see anything that high voltage in current use. My bil programs the major manufacturer of vfd's for the whole state of AZ. Everything from sky harbor, universities, to slaughter houses... I don't see that high voltage used commercially

[svandamme]

German consumer grid 3 phase is not 700 but 400 volts
Same as most of europe.


if that welder ran off 700 volts, then either he had a serious generator or he was working in a factory that has it's own high voltage convertor to something non standard
or that 7 was just a funny looking 4...
