22KW charging

[DragonRR]

What exactly would be wrong?

I think he is referring to your comment " 380V 30A, gives me 34.2kW "
W=V*A
380x30=11400W (11.4kW)

EDIT:~
Which would be correct(ish) for single phase but not for 3 phase! (My error) As mentioned by Scandinavian in a later post the correct figure is around 20kW.

Here in the US, it is my understanding the 22kw charging will come in the form of an upgraded charger, and that the 22kw charging is not limited by the car.

I am also told that both the 2020 and 2021 will be able to use this new charger.

They do not have a date yet on the delivery of this charger.

It’s the inbuilt charger that’s the issue. I have a 22kw charger but the car charger will only allow 11kw

I was told by my dealer that MY20 cars would not be upgradeable to 22kw A/C charging.

I totally agree but a s company owner it currently makes sense to purchase outright and get all the tax benefits. I agree also with 11kw for night-time charging but the 22kw is so useful for during the day, especially on a car with relatively short range.

I thought the same about the 22kw being handy for daytime charging. The reality is that you just Charge at DC if you really need to. Don’t get me wrong I’ll have 22 over 11 any day, but it isn’t really needed.

I agree with you in principle @Gogs . The problem I have found is that the 50 kW chargers seem to be more prone to be out of order ( nearly 2 out of three)than the 22 kW chargers around me. I guess this can be partly explained by the number of Renault Zoe that are driving on the roads here. And the Zoe charges happily at 22 kW. In these situation going from 50 kW charger to an 11 kW charger is a PITA!

Sorry @feye, I missed your question here.
What I meant was that you quoted your power to be 3 phase 380 V, 30 amp.
That should give you 380*30*1.73= 20 kW. Max if the power factor is 1.0

You may have an even stronger electricity supply of course but all above 16 amp is academically since the car will not take more.

Thank you. You are right, of course. So even though my current charger could handle 32 Amps as per display and 22kW as per label on the back side, the car draws 11.2 kW, that would be 400V*16A*SQRT(3) for the 3 phases.

Yes! The consumption is so low, the battery so big, really no need to charge all the time, unless you have long distance every day...

And this is pushing the car in city driving with a couple of LCs.

 

[feye]

honestly I’m tired of AC charging limits...

You are on the right track:

Maybe I should find a dealer and test this charger with my Taycan.

Yes it would be interesting to hear the price level of such a charger. The only ones I have seen so far are very expensive!

I think also ABB have launched one recently but have not been able to find any price indication.

Guess the PMCC will be with me for quite some time yet

 

[Scandinavian]

Actually @daveo4EV there are quite a few dc chargers available.

Here is one with 60 kW! But they are available up to 175 kW.!!

The new one from NIO should be around 2500 USD including installation. But of course only for the Chinese market for now. But I think they will sell their cars in Germany soon.

 

[daveo4EV]

so far I’ve found nothing “affordable” that also works on single phase residential power in the US - but yeah I think for more than 60 amps AC charging FastDC is the way to go - now all we need is a residential appropriate price & capacity.

I have gone back to my dealer and asked him again. If he is wrong, this would really be disappointing. You can't imagine how many times I have asked him, and he says he personally spoke to someone at Porsche USA that had the answer.

More to come...ugh!
