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.
Porsche plans network of 500 fast chargers for U.S.
More news on Porsche's plans to roll out their superchargers to 189 dealers plus 300 additional locations in North America supposedly by the end of 2019. They will charge for a charge but are vague on the price.
They seem to have figured out that they will need a battery at each site to support the high charge rate (and probably avoid high demand charges from utilities).
How do they count these? 500 locations with one charger or 500 charge poles or something else?
300 locations across the US with a single charger won't help much unless they don't plan to sell a lot of their Mission Es
Not sure how a US Tesla would charge from a CCS
I think it's 500 fast charger stations. Sounds like most would be a single station at a single location. They are going to tell their dealers they have to have it installed by the end of 2019. They are "exploring" working with ChargePoint, EVgo, etc. on the 300 other stations but don't hold your breath. Maybe 2020, maybe later. (Don't plan a trip for a while.)
No need. We have our own
It’s all a bit vague as these articles often are.
My take on this here:
