I wonder if people do not see the 500 kW as an issue or believe it will be magically resolved even though most places have problems even with normal homes and their needs...

I was going to say, 500kW is a lot of power. A charging station with multiple chargers is going to need a god damn substation.

So? What's the problem with that? You aren't going to pull a few MW out of the low voltage net in any case

Convenience. Places where you can create new mid voltage lines from main station and places where people go in mass will rarely coincide.

No, a super charging station can slower charge a bank of capacitors. No substation necessary. The amount of time it takes to pull out and pull in a fresh car & hook up doubles the real world time, while your active charge is about 12 minutes.
It seems to be designed to pump out 60A at up to 800V.
So a 600A service is pretty common at 480V for commercial buildings (you can get more I'm just saying this is a really common service). A capacitor bank and a good control unit should make light work of it.
Keep in mind doing fast charging is super bad for your batteries. Also at a local grocery store that has a super charger (they advertise) using that feature costs a few more bucks I'm assuming to discourage it, possibly to get you to shop there and wait longer.

Yeah that's an insane amount of energy. But maybe it could work if they built them at wind and solar farms if you're passing through lol

A few kW isn't enormous.. lol..
Eokokok t1_j1lij2a wrote
500 per single station is not? Sure.
Schemen123 t1_j1lirhr wrote
Compared to what big machinery needs? No.
Companies regularly pull MW out of the net .
Eokokok t1_j1livg1 wrote
You compare a whole company to needs of handful of chargers? You do not get how insane this is? As a low-mid voltage certified electrician let me tell you - it is mental.

A quick googling says an average nuclear plant generates about 1 GW. That's about 2,000 cars to consume the output of an entire power plant. 500kW is an absurd power draw for a car. We're going to need massive upgrades for the electric grid as EVs become more popular.

Yeah comparing installed power to used work.. slow clap.. Watt and Joule are properly rotating in their graves.
You only need to recharge whatever is used and that isn't all that much more than currently provided by the net.
Plus
Those 500kW are also just peak power and will only be required for a few minutes per charging cycle. 500kW flat would charge even an EQS in less than 12 minute from 0 to 100 while in reality you never will see a flat 500kW consumption.
In the end those 2000 500kW chargers will maybe pull half at peak power and that only for a few minutes per day distributes over thousands of square kilometers.
Because no one will need that much one location.

They will have to be strategically placed near high voltage lines.

You can pull enormous amounts of powe out of the middle voltage powe nets if they are set up properly.
The issue here is that the current infrastructure was juuust good enough to support what is required and now needs modernization anyway.

I mean there are already several 6-8 bank 300kw stations throughout the country.

Oh, a blind man with a brain can see it. The switching gear and copper cables coming from the power plant will be similar to a manufacturing plant requirements (per charging station).

They would be aluminum but I get your point.
