Featured Porsche to add 250 miles EV range in 20 minutes

Technology changes and you hope folks figure it out before it is too late. Yes, we can remember the struggles of the past but those problems are gone. I wish Porsche luck to figured out today's problems.

Well, unless my fortunes change dramatically they can guarantee I shan't be buyings Porsche!

 

agreed, you should buy one.

 

I might buy one from their parent company when their "Filmore" van comes out.... something Toyota did not want me to own... not even their hybrid van.

 

good luck with that.

 

Not my zip code...

 

therein lies the rub...

 

I don’t quite understand the hostility?
Isn’t it a good thing for any company to make cars that are more efficient?
If Porsche managers to deliver, that is wonderful.

 

hype is hype, action is wonderful. i should have been born in the show me state.
also, a fast charger at every dealer is not much action.

 

Just considering Porsche's parent company .... the last boast VW made, was their quick chargers were going to be 600V. Ok - so that'd likely mean ZERO compatibility w/ ANY existing charger tech. Great. So much for one big happy plugin family. How's that going to spur plugin growth.
High voltage like that, also means their business would need to install a LOT of HV transformers .... which cost a whole lot more (not even counting install costs) than the DC QC itself ....
So that means the dieselgate billions in fines that'd be used for QC infrastructure will be reduced significantly - total quantity-wise. The most optimistic thought might just be - wait & see.

The CCS group is trying to extablish a standard for up to 1000V. The Porsche chargers are 800V, but can also do lower voltages. A battery pack built to take 400VDC or 800VDC would likely have 2 400V modules that could charge in series @800V or parrellel @400V. I'm not sure what the problem is?

Chademo is too slow 50 KW now is proposing a double to 100 KW. Tesla is talking about a mega charger that will likely be at this porsche voltage or higher.

Tesla Says Sub 10-Minute Supercharging is Possible

Let's not limit ourselves. I do believe if tesla had megachargers out porsche would use them. If porsche gets these 350 kw ccs chargers out tesla will probably use them for its new roadster. These companies can help each other. There is not much of a technical hurdle here, its a question of what the standard will be and if infrastructure will be built. The tesla/porsche talk pretty much kills an idea that chademo will be a major playing in north america or europe.

 

‘Supercharger for all’: The first 150 kW fast-charging station comes online in Switzerland | Electrek
After reading the article above, it looked like there was no preference in nozzle, only that their150kW capability was limited by the fact no present day cars are able to receive that much power.

Well yes of course there is a preference in connector for 150 KW. CCS. Chademo peaked at 62.5 KW when those were designed. In that diagram the Chademo fast charging is 50 KW. If the market demands faster charging my guess is it will have to change the cable/connector specifications. CCS appears to be fine to 350 KW and tesla is likely fine here too, CCS is studying it, and now has a 150 KW standard, but few if any chargers that can do it.

The fact that these fast chargers have multiple connectors make sense. They will charge more though for a chademo charging at 50 kw than a porsche in 2020 charging at 150 kw (or a tesla if it gets a ccs adapter). The charge includes a price per minute, faster charger can recharge power at a faster rate per minute.

That link was from 2016. There are a lot of test mules that can take 150 KW on CCS today. Bolt charges at 55 KW, but I can definitely see people upging the rate when the new battery cells (coming out this summer) make it into cars.

 

Better the dieselgate public service go to any chargers than to hydrogen stations like some in CARB want.

 

Baker, CA was supposed to finished their 4 stall 350kw QC stations last summer. But delays with permits and then mistakes are stalling from being finished.

 

how many chargers has porche installed so far?

 

i suppose that's like saying better to have the Hillside Strangler as a neighbor than Ted Bundy.

.

 

have they built any cars yet?

 

I'm surprised no one has questioned the speed at which they claim this is possible. If they have changed battery chemistry...maybe. But if this is lithium then I question the hype here. Tesla/Elon has said on multiple occasions that there are reasons they limit to 120/130kW with the biggest reason being battery longevity. I'm guessing we'd see some Leaf style degradation on these vehicles if they are still lithium.

 

it's easy to make claims when you have no intention of following through in the near future. people have short memories.
