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

[krissrock]

what amp circuit are you guys testing these on? 40, 50, 60 amps?

 

[daveo4EV]

60 amp circuit in the US - with an EVSE configured for a 60 amp circuit t- vehicle should charge at 10.8 kW as it does in Europe.

I've tested 3 separate EVSE's

1. Tesla Universal Wall Charger configured for 60 amp breaker - 48 amp charge rate - result - max charger rate 40 amp (9.3-9.5 kW indicated by Macan)
   1. this charger is known to operate at 11 kW with other EV's (Taycan, Audi eTron SUV, Tesla Model Y)
2. Tesla Gen1 Wall Charger @ Seascape Resort Aptos, CA - configured for 100/80 amp charge rate - max charge is 19.2 kW - Macan result is 9.3-9.5 kW indicated max charge rate
   1. this charger is known to operate at 11 kW with other EV's (Taycan, Audi eTron SUV, Tesla Model Y)
3. Blink public charger @ Santa Cruz Wharf - max charge rate 15 kW - Macan Result is 9.3-9.5 kW indicated max charge rate…
   1. this charger is known to operate at least at 11 kW with other EV's (Taycan, Audi eTron SUV)

my 2024 Macan Turbo EV appears to enforce a limit of 40 amps @ 240 volts - resulting in a maximum charge rate of 9.6 kW when standard equipment specification indicate a maximum on board charger of 11 kW…

50 amp circuit is 40 amp charge rate - or 9.6 kW "raw" - we're seeing 9.3-9.5 kW on 50 amp circuits as expected.
40 amp circuit is 32 amp charge rate - or 7.68 kW "raw" - I've not tested but have no reason to believe the Macan would not charge at 7.xx kW on a 40/32 amp circuit.

Macan Standard equipment is listed as 11 kW on board charger for North America - and yet we can not get it to charge above 9.6 kW (indicating a 40 amp cap/limit)

the limit is either hardware (porsche factory shipping w/9.6 kW onboard charger)

or

software - a configuration in the vehicle that limits the max charge rate in North America to 9.6 kW

I'm betting on a software/configuration limit - and I'm betting the limit is unintentional or confusion - Porsche historically has been confused between the maximum charge rate of a _MOBILE_ EVSE in North American being 9.6 kW, but the vehicle can charge faster than 9.6 kW with a non-Mobile hardwired EVSE - Taycan's spec's were confused for 4+ years - and local service claimed the maximum charge rate for Taycan was 9.6 kW even when I could demonstrate an 11 kW charge rate in their service bay with an unmodified Taycan…

my next step is to reproduce the charging limit at Porsche Service center with a Porsche Wall Charger known to be configured for maximum charge rate of 19.2 kW - they have at least 3 of these at my local deal for testing the 19.2 kW onboard chargers w/Taycan's

Demonstrating that my Macan can only charge at 9.6 kW or less on a Porsche EVSE configured for 19.2 kw should be enough to raise a ticket/question with PCNA for clarification from my local service guys - we'll see where it goes from there…

HI

In the Porsche UK configuration tool it states:

Charging Technical Data:
Charging time (AC) at 9.6kW (0 to up to 100%) 11.5 h
Charging time (AC) at 11kW (0 - 100%) 10.0 h

In the US it states:

Charge Technical Data:
Charging time for alternating current (AC) with 9.6kW (0 to up to 100%) 11.5 hrs

It would seem intentional that the US models are limited to 9.6kW AC charging given they have omitted the 11Kw charge rate from the specifications - even if they have actually fitted an 11KW inverter.

That said, hopefully it is just a software limit that Porsche will provide a fix for at some point.

please see post #3 of this thread where I have copied the North American Standard Equipment list from the Porsche website for the Macan EV

https://www.macanevowners.com/forum...sla-universal-wall-charger.18123/#post-273413

it clearly lists an 11 kw onboard charger.

 

[ChrisFromUK]

I agree it lists an onboard 11kw charger.

Just pointing out that in the US, Porsche is only listing 9.6KW in the charging specifications and that seems to be what the actual limit is.

In the UK, they also list an 11KW charge rate in the specifications and it seems that rate can actually be achieved.

So my guess is that there is in fact an 11KW inverter in the US models but it is intentionally limited to 9.6 KW - don't know why that would be though.

It might be a setting, assuming the onboard charger is programmable (remember how enabling PnC required replacing the entire onboard charger on Taycans?). Furthermore however, remember that >9.6KW in Europe is only achievable with 3 phase AC connection. This means there are no single phase wires between the port and onboard charger which can handle sustained 48A current, they instead split the power between multiple wires (16A per phase max?). So it is possible that Macans in NA have wires only good for 40A, not 48A. It wouldn't be the first time Porsche speced the absolute minimum size of wiring for their spec, and in this case perhaps the NA spec was communicated internally as 9.6KW. So even if you find the setting, I would suggest verifying the AC wire gauges inside the car (from port to onboard charger) before enabling it.

Edit: I wrote the below before I saw ChrisFromUK's post immediately above. What Chris says is conceivably consistent with what I'm saying below, other than the fact that the owner's manual does show a 11 kW charging time.

It just doesn't seem that likely to me that Porsche would put a different charger or wiring in NA-bound Macan's from the rest of the world. (Though possible: for example current Volvo PHEV's have 3.6 kW built-in chargers in the U.S. and 7.2 kW in Europe).

The issue here is that in advertising materials and the spec's provided by Porsche on the US configurator, and also in the digital owner's manual, Porsche claims (or at least strongly implies) an 11 kW charger, but the cars only charge at less than 9.6 kW on all the EVSE's we've collectively tried. There is also sufficient evidence to show that Macan's in Europe will charge at near 11 kW if the connected equipment allows.

What I'm wondering is: is it possible that the Macan will only draw ~ 11 kW if it is on a three-phase circuit, but will limit itself to < 9.6 kW if it is on a single-phase circuit? Virtually all US domestic household circuits are single phase, but three phase is often supplied to industrial sites, and also, I believe larger residential and commercial sites (though it is stepped down on site for distribution).

I say this out of ignorance, but are there EVSE's in the U.S. that can be connected to a three-phase circuit, and if so, I wonder if the car would then allow the higher draw.
