Porsche installs first ultra-fast 350 kW EV charging station
Where is this located?
What type of connector is it? Which standard (or is it proprietary)?
Does it "charge" (cost?)? (I don't a UI for payments)
I guess you didn't read the link?
Read the article at Porsche installs first ultra-fast 350 kW EV charging station
That's all we know right now.
Built in lightning protection? Might make for a good 4th of July...
It's in Germany... now they need to make a car that can use that charger
Spec is 1000V and 400A. So basically CCS 2.0. The connector profile can be the same as CCS given modest current boost (wires inside have to be updated, and perhaps it needs liquid cooling). The Tesla connector already goes to 370A.
This requires the new 800V battery pack that Porsche will be doing. It'll be very interesting to see how they handle backwards compatibility to 400V chargers on the car.
800 Volt batteries are the only way to significantly increase charge speed. Tesla will eventually do this as well. Maybe as soon as with their all new Model S next year. The 350+ Ampere on current Superchargers is already causing a lot of heat at the connectors. Doubling the Amps would quadruple the losses and heat build up on all connections. Doubling the voltage causes no extra losses at all. By increasing the voltage you can get more power while having the same losses. It makes sense to go to a higher voltage.
"Porsche claims that it already has the backend to support 350 kW charge rate, it can currently charge at 50 to 150 kW until vehicles can support higher charge rates."
So Porsche is the first to install a 350kW EVSE that does not actually support 350kW.
