[North American] - Macan does NOT support 11 kW charging??? Home / Residential charging update (using Tesla Universal Wall Charger)

[DuckMan]

owners's manual in my app lists 11 kW charge rate times - I plan to engage my dealer service in the new year to follow up on this…between the 11 kW listed in standard equipment in the configurator and the refers in the owner's manual - I think this is a configuration mistake with North American regional settings that can be rectified with coding/software changes…but we'll have to see how this plays out…

Notified dealer on Porsche survey about this issue. Not a peep.

I don't know if you folks noticed, but on this thread the posted Audi SQ6 sticker states 9.6kW onboard charger. So I'm not sure what that says about our Macans.

yes I found that very interesting…

this wouldn't really be an issue for me if the damn porsche charger was long enough

Not having a Porsche EVSE, I'm not sure exactly what this refers to, but if the issue is the charge cable is too short, you do know you can get an extension, right? (Not saying whether they're good or bad, just that nominal 48 amp versions do exist).

no i didn't know that... is it a generic extension? you got a link? i've never heard of an extension to the charging cable... The Porsche cable is definitely too short.

My plan was to get a nice charger, i have a 60 amp set up in my garage... but if I don't see the point of spending the money if i can't utilize the extra amperage. Might as well just use the porsche one

Search "EVSE extension cable" on Amazon. Note: I don't know if any of these is certified in any way.

For the cost of the extensions, I would prefer a dedicated wall mount Charging unit with a built in cable long enough for your purposes. I have two Chargepoint Home Flex's, the oldest one being in use for 4 years now with no issues whatsoever. What I like about the Homeflex is the quality and compliance of the cable and the ergonomics. The aesthetics are nice to, It has a self retracting socket holster that is surprisingly satisfying to use. - video attached

Here is an extension : J1772 Extension_ amazon

Now that I've arrived home I've been able to accomplish some charging with my home residential charging system.

I can report the following:

• so far the Macan EV works just fine with the Tesla Universal Wall charger(s) I having installed sharing a 100/80 amp dedicated charging circuit
  • last night my Cayenne eHybird and Macan charged no problem!
• the 11 kW EVSE I have yields a 9.3/9.4 kW reading inside teh Macan EV - this would indicate a charging overhead of 1.6 kW - this is much much much high than my 2020 Taycan Turbo on the same charger and same circuit - this will require more investigation - but that is what I'm seeing
  • my 2020 Taycan Turbo would report 10.4 kW inside the vehicle when charging from 11 kW EVSE - a more reasonable 0.6 kW of overhead/loss
• when charging with 40 amps (9.6 kw) the Macan EV reports 8.3 kW inside the vehicle - still a 1.3 kW "overhead" as reported - again not sure if this is accurate, more investigation is required - I'll try and get to the bottom of the issue.

the Macan's charging configuration User Interface is much much simpler and easier, and more easily understood in my opinoin - it's a big improvement vs. the Taycan charging user interface

however, you still can not achieve the very simple: start charging at this specified time - Porsche is still "all in" on departure time scheduling - which requires some mental gymnastics to work out if you want to push the charing schedule into a time-of-use off-peak rates schedule.

also I plugged in after returning from my cross-country trip - and was below 25% - and it immediately started charging - even though my depature schedule was over 12 hours away and my allowed time of use for optimizdd charging was midnight-15:00 - reading the manual confirmed there is a 'fixed' charging behavior to always charge to 25% if you plug the vehicle in. I confirmed this was happening, and the charging stopped at 25% - and then waited to finish charging to 80% based on my charging schedule.

this is an unfortunate behavior and there is no way that I can find to disable it - or adjust the 25% threshold - grrr grrr grrr…

this will go "on my list" of things I request Porsche to update/fix - there must be some way to have the vehicle plugged in and yet not charge outside the window for optimized charging.

that's all - I'm sure I'll learn more in the future.

UPDATE: my 2024 Macan Turbo EV appear to only support a maximum charge rate of 9.6 kW - this differs from the onboard charger specification from the Porsche USA website and standard equipment list for the Macan EV - I have an eMail out to my dealer/service-manage asking for clarification - we'll see what they say in response.

FYI - I have the same Tesla Universal J1772 wall charger and

FYI - I have the same Tesla (universal) J1772 Wall Charger and found a similar setup with my BMW X5 50e and scheduled charging. It works better to use the Tesla app and control everything via your Tesla Wall Charger. I simply programmed the Tesla unit to only charge during the best time of use periods. You will need to setup the wall charger via the app on your WIFI network with Internet access. After that, you can setup scheduled charging. I am on Southern California Edison and just need to avoid 4-9 PM. I set the wall charger schedule to wait until after 9 PM to start and enabled the BMW to charge immediately when connected. You should be able to do this on the Macan EV as well. I am awaiting deliver of my Macan - it's in transit now and had planned to run it the same way I do with the BMW. I previously used the scheduled setup with departure times on the BMW - it worked, but as you noted was a tad complicated. I would expect it to be more of an issue with the Macan as it will typically charge longer - my X5 only has a 25 kWh battery.

In short - control the start and shutoff control from the Tesla unit and not the car. Then simply avoid the highest time of use period(s) for your utility plan.
