[Poll] - Porsche charging specification lie? Macan is not allowing 11 kW max charge rate - capped at 40 amps? 9.6 kW max rate.

[Petzi]

I'm sorry, but this is simply not true (that this is an "assumption"). Who has 3 phase residential AC in the US, and which EVSE in the US is 3-phase capable? Porsche clearly stated that US Macans could charge at 11 kW for many months. They no longer make that claim. This was both in press releases and published specs. Every other car that claims 11kW in the US that has tried in fact charges at that rate on my EVSE'S.

I don't understand this discussion at all. The car (any car) can only charge at the speed or power that is made available to it.

With the macan, that's a maximum of 11 KW. But that's no guarantee because you can also connect the car to a normal household socket and then it's only 1KW or less.

This discussion is just as absurd as claiming that the stated maximum speed of the Macan is a "lie" because there is a speed limit almost everywhere in the USA and therefore you can never drive that fast on a public road.

In the US we don’t have a three phase compatible connector on the car though.

Also EVSEs, even the high priced 19kW+ capable Porsche unit, use only two legs of the three phases. Which provides less power than the split leg 220/240 V. Another area where the uninformed general public could be mislead. They are compatible with three phase power, but don't pass it through.

Good info, allow me to add:
In America you can connect EVSEs to:

1) 240V Split-phase
This is your single phase (residential buildings)
You have 3 wires, L1, L2, N
If you connect any line to neutral we get 120v
If you connect L1 to L2 we get 240v
So 240V x 40A = 9.6 KW

2) 208V Wye
This is your three phase (commercial buildings)
You have 4 wires, L1, L2, L3, N
If you connect any line to neutral we get 120v
If you connect any 2 lines we get 208V
So 208V x 40A = 8.3 kW

Now on the American market car side you have a J1772 connector (or 2 if you have 2 charging ports like on the Macan)

As you can see from the image above it only has 2 lines L1 and L2/N

This gives you 3 choices:
1) Level 1 charging (120V), L1 + N
2) Level 2 charging (240V), L1 + L2
3) Level 2 charging (208V) (commercial Wye system), L1 + L2 from different phases

you are simply wrong - Porsche ships a 11 kW EV in the US - it's the Taycan - it's charged at 11 kW since introduction - it's reasonable to assume when porsche claimed the Macan could do 11 kW it would do it the same way the Taycan did it on North American single phase 240V 48 amp EVSEs

Porsche screwed up - quit trying to make excused for them. There is NO SUCH thing as 3 phase North American EVSE - the J-1772 standard does not have enough electrical conductors for 3 phase charging - and many many many North American EV's charge at 11 kW or more - including VW and Audi products.

porsche scewed up - plain and simple.

who cares ?

who cares ?

anyone who purchased the vehicle believing the North American specifications as published by Porsche were accurate?

Peter, you are not in the US so perhaps are unaware. In the US we can have 120 or 240 V single phase and a range of different amperages. By code, the maximum permitted plug in amperage is 40 A so 240×40 = 9.6 kW. Hardwired, we can go up to 80 A. My EVSE is on a 60 amp circuit and by code is permitted to advertise 48 A to the car. 240×48 is about 11.5 kW. So those of us who saw 11 kW advertised by Porsche, yes "assumed" that meant using most or all of the current in a 48 amp permitted circuit (i.e. 60-amp circuit).

Friends of mine with different cars, when plugged into my EVSE take somewhere around 11.3 kW; my Macan takes ~9.3 kW on the same circuit. That's the issue.

So, yes, technically this is an assumption, but really it is the most reasonable assumption if one wants to believe that Porsche is trying to communicate accurately. The fact that Porsche has stopped promoting 11 kW charging in the US and now is promoting 9.6 kW charging is evidence that the prior claim was incorrect. I don't think any of us has said it was deliberate (although I guess the title of this thread might imply so.)

(Note, post edited for clarity once I could get to a computer to clean it up).

BTW, without naming names, someone claimed that PCNA never "advertised" an 11kW charging time in the US. This is false. I don't blame anyone for not reading through this entire thread, but you can look here. Below is a screenshot of the owners manual I downloaded for my car (a US Macan 4). Do people truly want to continue to claim that Porsche did not miscommunicate on this subject? (I assume if people are simply tired of this subject, they could choose to stop talking about it rather than continue the argument). And also, BTW, in my case, my cable run to my garage is over 150 feet. The difference in cost for a code-compliant 150 foot cable run to support 48 amps continuous vs 40 amps continuous is a bit more than $50. Just saying.

That screenshot is the same in every manual and every Porsche website for all markets. To be 100% clear that is what I see in my European manual for my European Macan.
It simply means 9.6 kW where applicable and 11 kW where applicable and so on and so forth.

It’s a miracle we don’t have folk claiming to have installed a 19.2 kW (NA) or 22 kW (Europe/Uk/etc.) EVSE expecting a full charge in 0.00 h as stated in Porsche Macan website above. J/k

Yes, but you CAN get 11kW charging in Europe.

 

[dgkhn]

Actually, I give up. I just downloaded the most recent manual, which still shows the 11kW info. It also says "Only charge the high-voltage battery at domestic electrical outlets if no other charging option is available." Above that, it recommends using "industrial sockets." Below that it says, "the excessive use of fast-charging stations (DC) will increase charging times in the long term. Charge in the home environment with alternating current (AC)".

Yes, I could twist and turn to make sense of that word salad, but I choose to surrender.

 

[pm4s]

Of course I can as
11 kW is for Europe and
9.6 kW is for NA

same as 230V / 50Hz / PAL for example is for Europe and
120V / 60hz / NTSC is for NA

Fine but most other EV's in North America can charge at a faster rate than 9.6 kW on a 48 amp EVSE while the Macan cannot. It is what it is.

That’s because the Macan is capped at 40Amps
240V x 40A = 9.6kW

I am more content to pretend that is sarcasm.
