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

[pm4s]

I am more content to pretend that is sarcasm.

I was being serious but I am willing to try one last time (sarcasm included).

Porsche lists charging times in a standardised format for all markets:
9.6 / 19.2 kW
11 / 22 kW

[sarcasm part]
American see this 9.6 kW that must be for other markets where everything is small that can’t be for us, everything is big here, installs “11 kW” cable/EVSE, enters endless debate when it only pulls 9.6 kW blaming Porsche for misinformation, waits until darkness to leave house avoiding shame from 11 kW charging neighbour[/sarcasm part]

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.

It’s actually very clear. Use industrial sockets (outlets) because they can resist the generated heat and not melt down. Avoid regular domestic outlets for the same reason and also because the wiring and electrical fuse are not likely to be appropriate thus likely to malfunction or become a fire hazard. And DC charging constantly in the long run may decrease the lifespan of the high voltage battery. There are threads here explaining all this in detail.

Good info, allow me to add:

Yes, also keep in mind that many areas of the US (rural) have 115/230 not 120/240 which seems to have some impact to the charge rate.

Here is what is pretty clear at this point (yes, I get that some people were trying to convey this recently, but in a kind of nasty way, while refusing to acknowledge that Porsche caused the confusion in the first place--said confusion being the real source of the original angst).

It seems that this is the situation (stated more clearly IMHO): Single phase AC (NA), the Porsche OBC maxes out at 9.6kW (240V x 40 amps) even if on an EVSE/circuit capable of supplying more than 40 amps. Three phase AC (e.g. parts of Europe), the Porsche OBC maxes out at 11kW (230V @ 16 amps three phase).

In contrast to Porsche, for example, the BMW USA website simply quotes a max charge rate for the BMW iX of 9.6kW, while the BMW UK website says 11kW. Porsche could have clarified this easily (by either appropriately quoting the correct number in each country) or by parenthetically stating the power supply details (as BMW is now doing with iX3 specs).

BTW, seeing that BMW is quoting 9.6kW in the US and 11kW in the UK for the iX (which is apparently the same capacity as the Macan) makes me wonder whether there is a common underlying basis for engineering the OBC/software this way (or maybe the issue is the source (actual manufacturer) of the OBC itself and Porsche and BMW have something in common in that respect? (I have seen forum posts suggesting the iX can do 11.5kW in the US, but BMW doesn't seem to be claiming that. I am not clear what Audi and VW are claiming at this point and I have not researched it.)

Anyway, I would like to take this opportunity to express my regret that some posters here have chosen to personalize this issue, or at least to post snidely; that is unfortunate, unnecessary, unhelpful, and unappealing. Yes, yes, it's the internet. I have come to expect better on this site most of the time.

oh provoking everyone with a complete non issue, never letting it go, never considering anything somebody else is saying but complaining about the "internet "

 

[ColdCase]

You know, I've never found Porsche owners manuals and site information completely accurate or consistent in detail, especially when there are engineering (software) changes. They seem to be better overal than others, however. But then I have a small sample size.

I've written tech manuals, and supported tech writers. Keeping informed of changes and clarifications is an issue, and there is a relatively long review cycle. It is just not the top priority. You will find plenty of sections well written, some not so much. Now that AI is getting involed.... watch out

 

[jwatte]

there is a relatively long review cycle

There doesn't have to be, but old companies with slow processes, prefer it that way for some reason.

Well I too, who has a build going for a 2026 Macan EV saw clearly the 11kW OBC but also saw lots of inconsistencies also showing a 9.6kW OBC. I wrote to the Porsche North America spokesperson, shortly after the online configurator was cleaned up showing only a 9.6 kW OBC.

Earlier posts speak of the Taycan, I had a 2020 Taycan 4S and a ChargePoint home flex hardwired and configured as 48A. Below you can see the Taycan taking 11kW and a Macan EV loaner pulling 9.3kW. My house voltage runs around 235VAC. The Taycan only shows 10.5kW but that is to the battery after losses.
Taycan:

2025 Macan Loaner:

I don’t want to make a huge deal of this, but I am disappointed that Porsche was unable to provide an 11 kW on board charger for a vehicle in this price range. Note that the new 2026 Chevy Bolt EV coming out at under $30,000 has a 11 kW on board charger for the USA market.

I also see the same thing and I also have a taycan, the second gen taycans also have 11kw obc spec in the US but it’s either limited or “misspeced”
I currently have 2 J1.2 taycans and they both can pull only 40amps while my older taycans and Audi RS Etron GT pulled for full 48amps.

I'm glad Porsche finally updated the North American spec to be correct

I'm sad that it is only mediocre in the North American EV world
my 2020 Taycan could charge at 11 kW so it was reasonable to assume the Macan would also (especially when it was listed as 11 kW on the North American Porsche website)…

but it is what it is at this point and at least Porsche's site is no longer inaccurate.
