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

On the subject of whether the Macan shows gross power flow: I just tried the Macan on my 240 volt 16 amp EVSE. The Macan showed 3.8 kW (which would correspond to the maximum gross the EVSE should be able to supply. The EVSE itself displayed: 237 volts, 15.7 amps, 3.7 kW. Aside from the minor discrepancy, it is interesting that my car shows the full rated power on the 16 amp EVSE, but maxes out at showing 9.4 kW when supplied by my ChargePoint at 40, 44 and 48 amps. (Even at 40 amps, it should really be 9.6 if it is taking the full draw.)

Edit: on thinking about this a bit more: in the case of the 16 amp EVSE, the EVSE would be telling the Macan, "my max is 16 amps." If the Porsche power meter is anything like its speedometer, then maybe the Germans actually built in a little wiggle room there, so it doesn't over draw? (Meaning, it takes 3.7 kW when the limit is 3.8 by being a touch over optimistic--so the car says 3.8 when it's really taking 3.7?) Then again, that would be inconsistent with the conversations about the car taking 40.7 amps when it should be taking 40.

The 40.7A was shown on Dave's Porsche EVSE, so it was end-to-end Porsche environment, meaning we're dealing with some sort of German precision example (either measuring or actually consuming). Perhaps they need some Swiss watchmakers on their team to improve their precision?

I voted #2. Macan 4 with a span drive on a 60A circuit - Colorado

Just brought home a Macan 4S - Colorado. I'm using a Tesla Wall Connector on a 60 amp circuit with a TeslaTap 50 amp adaptor. Both wall connector and Macan show 9.4-9.5kW. The model Y I had previously charged at 11kW / 48 amp.

I guess I'll have to get used to 15% longer charger times

Give @daveo4EV some time, perhaps he'll get to the bottom of this with PCNA.

My belief is that the Macan 11KW inverter is limited to 9.6KW per electric phase.

So at charging sites with 3 phase electrics/chargers you get close to 11KW charging on the Macan.

At charging sites with single phase electric/chargers you are limited to 9.6KW even if the charger can supply 11KW or higher.

In the UK, the Porsche Technical Data is explicit that 11KW charging is possible:

"Charging time (AC) at 11kW (0 - 100%) 10.0 h"​

In the USA configurator, this statement is not present in the technical specifications, possibly because there are relatively few locations where 3 phase electrics/chargers exist.

3 phase electricity is not a thing in North America for EV charing - the J-1772/CCS1 standard do not even have the necessary electrical connections to support 3-phase being delivered to the vehicle - the only way 3-phase power is "supported" woudl be via a DCFast charger - where the DCFast charger is taking in 3-phase power but delivering DC power to the vehicle via CCS - bypassing the onboard AC/DC charger on the vehicle (note to self: most DCFast chargers in North America proabably are served by 3 phase power ;-) - but the AC power source doesn't matter once it's converted to DC power).

I would find this explanation viable except for one thing: The Taycan charges at 11 kW in North American, and so do the new 2024 Cayenne Hybrid's and so does the Audi eTron's (I haven't had access to a Q6 in North American)

I find it implausible that the Macan is the one product in the VW/Audi/Porsche line up that has a different AC/DC onboard charger…

I still believe it's a "setting" inside North American Macan's - that is the result of some confusion by Porsche between the limits of mobile EVSE's in North American (i.e. the one the vehicle ships with) which is 9.6 kW, and the actual limit of 11 kW which requires a hardwired Porsche Wall Charger or similar…

but proving that is going to be difficult.
