[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?

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…
