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

• 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.

Great info! Does this mean the only way to be able get a more precise and customized charging schedule would be to buy a charger that allows for it like the Chargepoint Flex perhaps?

Related to this, does the Tesla UWC not support scheduled charging for non-Teslas? (I don't have one, but am considering it)

It does have the feature, but the only thing is that you can only set one schedule for all days of the week.

• EV charging (from grid if needed)
• EV charging from excess solar
• Grid export from battery
• Grid export of excess solar

I also have the Tesla Universal. The Macan in the US market has an AC max of 9.6 kW, which surprised me. I think the European version has 11 kW.

Team,

The porscheusa.com website listed the Macan’s onboard charger as 11 kW…specific question is at the bottom - the rest is “background” and setup…


This is the same as the European Macan and the same as my 2020 Taycan Turbo had installed.

In North America mobile/plug-based EV chargers (EVSE’s) like:

• Porsche Mobile Charger Plus (PMC+) - included with Taycan and hybrids
• Porsche Mobile Charger Connect (PMCC) - optional $1020 unit w/Taycan and Turbo Hybrids (LCD screen + Wifi + 25 ft cord)
• Porsche Universal Charger (PUC) - delivered with my Macan…
• Others non-Porsche mobile EVSE units…

Are limited to a 50 amp circuit and a 40 amp charge rate providing a “raw” capacity of 9.6 kW/. This is true and factual and matches the exact expectations in practice as well as theory. This is because these units a “mobile” and NEMA plug based - and the largest NEMA plug allowed in North America for residential use is NEMA 14-50 or 6-50 outlet - which is a 50 amp circuit allowing for a 40 amp charge rate which at 240V is 9,600 watts capacity or 9.6 KW.

To achieve an 11 kW charge rate in North America requires a “hardwired” EVSE on a 60 amp circuit breaker allowing for a 48 amp charge rate - 48 amp charge rate is 11,000 watts or 11 kW “raw”

The sorts of EVSE’s that can provide this are hardwired:

• Power Wall Charger Connect - hardwire and allows from a 15-80 amp adjustable maximum charge rate (1.44 kW - 19.2 kW)
• Tesla Universal Wall Charger - maximum power 60 amp breaker - allowing for an 11 kW charge rate

When charging my 2020 Taycan on my home setup I used to get 10.4 kW charge rate on a 48 amp circuit (11 kW raw) and 8.4 kW when charging with a PMC+/PMCC or other 40/50 amp EVSE’s - this is because the Taycan appears to report the effective charge rate to the battery after charging losses rather than the “raw” power being provided - this is ok and expected - not a problem…

I now have my 2024 Macan Turbo EV:

When plugged into my 60/48 amp Tesla Wall Charger the Macan Turbo reports a maximum charge rate of 9.3/9.4/9.5 - this is inline with a 40 amp charge rate on a 50 amp circuit and 9.3-9.5 during charging simply represents normal/expect voltage fluctuations during the charging process…

When plugged into my NEMA 14-50 outlet with my Cayenne’s PMCC unit - the internal charge rate reported by the Macan is the same 9.3/9.4/9.5 charge rate reported by the Macan when plugged into my 60/48 amp capacity Tesla Universal Wall unit.

My EVSE’s are confirmed to provide 60/48 amps or 11 kW maximum charge rate:

My 2020 Taycan used to obtain 11 kW when charging from my setup
My friends 2021 Audi eTron charges at 11 kW when plugged into my setup
My son’s 2022 Tesla Model Y charges at 11 kW when plugged into my setup
Other EV’s that have 11 kW maximum charge capacity also charge at 11 kW when plugged into my setup…

But…

My 2024 Macan Turbo EV only charges at maximum rate of 9.6 kW

So my question(s) is to you and Porsche North America;

• Is this the expected behavior of the 2024 Macan Turbo EV - maximum charge rate of 9.6 kW?
• Is the standard equipment website wrong in listing an 11 kW on-board charger for the 2024 Macan EV
• Is this a hardware limitation - are North American Macan’s limited to 9.6 kW due to a hardware limitation?
• Is this perhaps a software limitation? If it is a software limitation can we expect a future update to “unlock” the full stated on-board charger capacity?
• Has anyone tested the Macan with a North American EVSE that can provide 11 kW?
• The observed maximum charge rate of 9.6 kW is inline with a maximum charge rate of 9.6 kW and a 40/50 amp cap matching the maximum power of a mobile EVSE (like the PMC+/PMCC/PUC)

The 9.6 kW maximum charge rate is a surprise because:

• This differs from the stated standard equipment list for the North America website
• It’s less than the gen1/gen2 Taycan’s which support 11 kW 48 amp charging in North America
• It’s less than the European Macan’s which support 11 kW 48 amp charging in North America
• It’s less than the 2024 Mobile Cayenne Hybrid’s maximum charge rate which support 11 kW 48 amp charging in North America

An 11 kW onboard charger seems to be the normal part in the supply chain so a maximum charge limit of 9.6 kW is both a surprise and a disappointment and inconsistent with other EV’s in the VW/Audi/Porsche universe.

Question: Is this a hardware limitation of the Macan? Or is this a Software limitation of the Macan? If it’s a software limitation can we expect that to be adjusted/unlocked with a future update? (OTA or dealer service based)

Final question - does the Macan really rally have a 9.6 kW onboard charger when the rest of the entire VW/Audi/Porsche line of EV’s and Hybrid’s support 11 kW48 amp charging? Wow!

I’m sure you’ll need to consult with PCNA and potentially Porsche Germany - I understand that will take some time. But I am requesting answers to my specific questions and explanation of the missed expectations from the specifications published on the North American website.

I came across the Out Of Spec channel mentioning that the US Macan version has a whopping 9.6 kW AC. I didn’t notice that info on the Porsche website, which is quite surprising.
