[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.

 

[dgkhn]

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.

 

[Petzi]

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.

 

[refazi]

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.

 

[daveo4EV]

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.

Hi all. I am new to this relatively old thread and before posting I have tried to read through much of what has been posted. I am not an electrician and don't know what I am talking about when it comes to EV charging measures but...I am an owner to a '20 Taycan 4s and also a '25 Taycan 4s CT. I bought the second Taycan after the launch announcement in early 2024 and paid particular attention to the charging specs and battery capacity of the GEN 2 Taycan.

like so many of you have observed about your Macans, all of the '25 Taycan literature on point told me of the home level 2 charging capability at 11 kws.

Like many on this site with their own Macan EV stories, I upgraded my home charging to a hardwired 50 amp charger on a 70 amp circuit (Chargepoint Flex--a great charger btw). Needed to do this because with two EVs, I wanted to maximize charging flexibility. I also wanted to maximize my charging when faced with limited time to charge from time to time.

My '20 Taycan happily draws the full 11 kw and in the car displays 10.4 to 10.5 kws. My '25 Taycan only will pull 9.6 kws and in the car shows about 9.3. When I discovered this in late 2024 I complained to Porsche. heard nothing. I have repeated these complaints. Porsche took the issue away in the fall and claimed to "study it". They came back to me several months later and told me that despite what my two Taycan's show in their car charging displays, they actually charge at the same rate!!! So it's not underperformance in my '25 Taycan charging, it's a mysterious software display issue! When I told them that my Chargepoint software tells me that they do in fact charge at different rates and that my car displays are likely correct.

No explanation or answer to that from Porsche Canada.

I have now upped the issue to a legal process available in Canada called CAMVAP which forces the auto manufacturer into binding arbitration over manufacturing defects. Will see how it goes.

While it appears that Porsche Canada (and USA) changed their Taycan configurators at some point in late 2025 to remove references to level 2 home charging times using 11 kws and now only shows charging times which show 9.6 kws.

That said, here is a link to the Porsche USA website inviting prospective buyers to find their favourite new Macan EV.
https://finder.porsche.com/us/en-US...ition=new&condition=used&engine-type=electric

You will see prominently displayed on each Macan EV now available the 11kw charging standard. in the technical specifications for each vehicle the same information on charging times continues to be featured for both 11 kw and 9.6 kw rates.

Porsche doesn't seem to understand the misrepresentations they are making and misleading buyers (like me) for their EVs.

I have the same exact expirience, first Gen taycan/audi charging at 48amp while second gen base/turbo s gen 2 and Macan EV charging at 40amps.
The specs for the US are simply wrong and PCNA is silent about it.

My main point here is that while Porsche North America has tried to clean up (hide) their marketing errors through eliminating it in, say, their car configuration tools, the charging data remains out their all over much of their marketing information.

I will see if this means liability for them in Canada.

 

[ColdCase]

I think I read somewhere that the Taycan 11 kw charger was an option and there was so many reliability problems with it that they dropped the option.

No question the documentation/marketing is a mess of confusion.

I think I read somewhere that the Taycan 11 kw charger was an option and there was so much reliability problem with it that they dropped the option.

No question the documentation/marketing is a mess of confusion.

11 kw is/was standard - and north American Taycan's for years demonstrably and provably were able to charge at 11 kW (48 amps) - and was standard since 2019 when the Taycan's were first sold
starting with the MY'2021 Taycan's 19.2 kW/22 kw-euro - was a $1680 factory option - but it has proven very very unreliable and even getting it replaced if it fails is hit or miss…

• Porsche removed the option form the 2025 Taycan's - as of date/time of this posting the 19.2 kW OBC factory option is absent from the North American configurator.
• there is no 19.2 kW option for the Macan's
• there is a 19.2 kW option for the Cayenne EV listed on the configurator at this time but no cayennes have been delivered so I take that with a grain of salt
• Porsche published a tech bulletin documenting the lack of even service parts to replace defective 19.2 kW chargers - they even provided written guidance to service personal about how to explain there would be no more 19.2/22 kW OBC's _EVER_…
• but after that tech bulletin some dealers have noted there are service parts available "in the future" - but no hard dates - but Porsche has back pedaled on the no 19.2/22 kW OBC - but none have been delivered so far
  • to date if you have a 19.2/22 kw Taycan OBC and it fails - the only option for a timely repair is to have service install the standard 11 kW OBC
  • there is no word as to if the mythical future 19.2/22 kW OBC has been redesigned and improved to avoid the rampant failures
• some customers with defective 19.2 kW/22 kW chargers have been downgraded to 11 kW OBC's when their OBC failed and there were no service parts - compensation for the change in spec is TBD and very hit or miss
• 2024 and later Cayenne Hybrids (and Panamera Hybrids) can charge at 11 kW - so Porsche's hybrids can charge at a higher rate than their full EV's

Taycan's have provably charged at a full 11 kW since introduction in North America - but sometime in calendar year 2025 both new and serviced Taycan's have mysteriously been downgraded to max 9.6 kW after various service visits with no disclosure from service that would happen…when questioned by the owners service will claim it was always that way when the customer can prove there was no such limit prior to the car being serviced…

Porsche remains unable or unwilling to document an accurate OBC maximum charge rate…and continuously confuses the maximum charge rate of a North American _MOBILE_ EVSE (9.6 kW) with the maximum charge rate of the onboard charger (11 kw or 19.2/22 kW)…

many service/dealers will tell you incorrectly the maximum charge rate of any L2 EVSE is 9.6 kW - but that's untrue and Porsche itself even sells a Wall mounted 19.2 kW EVSE - PCNA and Porsche dealers are very very confused by the different limited of "mobile" EVSE's vs. "hardwired" EVSE's like the Porsche wall chargers…

Porsche's various marketing matériels at various times have claimed 9.6 kW, 11 kW, optional 19.2 kW OCB charge rates for Taycan, and claimed the included EVSE is either a 9.6 kW max rate or 11 kW max rate (impossible because it's mobile)…

at the moment their Hybrid products with smaller batteries have a higher capacity OBC than their full EV's - which makes no sense…

Porsche has never acknowledged or explained the downgrade to 9.6 kW for Taycan or Macan

and in more confusion that is bound to lead to embarrassment - the current specs of the Cayenne EV are: 9.6 kW OBC max charge rate, optional 19.2 kW OBC, 11 kW wireless max charge rate - so you'll be able to charge your Cayenne wirelessly at a higher rate than the OBC for a hardwired EVSE? Again await the confusion in this space…

it's 100% a mess.
