AC maximum charging power

[Diego]

Same for Italy:

• home single phase, 220V 3/4/6/7 kW (and 7 kW, that I have fortunately, is not allowed everywhere)
• commercial and industry 3-phases 380V

So 11 kW is adeguate for home charging considering price and weight add on if they should decide to go for a 22kW system.

Wow, 3 phase home juice!? Not very common in USA in residential builds. Here I'm setting up a hardwire 60 amp station for Macan ev, and a seperate 30 amp plug for second vehicle (Rivian RT). Our electricity prices are amongst the highest in the USA states though due to the usual political horse dung with hydro electric negotiations with Quebec/Canada.

if you're going to own two EV's - recommend getting power-sharing/split-load EVSE (EV chargers) like the Tesla Gen3 Wall chargers or Enphase/Clippercreek...

you can then have each one have a full 60 amps when used "alone" -but when used together they will split your 90 amp total load between the two EV's

I have that setup at home for my setup and it works slick - and that way there won't be a "slow" charger and a "fast" charger.

you have the capacity (60 + 30 amps)…

check it out - you'll be happy you did!

Totally agree that's the way to go. However garage layout and need for 2 115v plugs on side with no power but with 30 amp box for wheelchair lift will just get a 230 V receptacle, good for 30 amp visitor. Will get a daisy chain for 60 amp side : )

I would like to know what is the maximum charge value of the Macan EV in AC.

I am evaluating the installation of a new charger and I see that to reach 11kwh or 22kwh it is necessary to install a three-phase installation.
The installer asked me what the maximum AC charging power of the vehicle was and all I have found are references to 11kwh, but honestly I find it strange.

May you please help me with this?
Kind regards!

Normally there is the option to upgrade from 11kW to 22kW as per Taycan (was problematic) but if not available then 11kW is your max.

3 phase for both needed but save some money and single phase at 7.6 kW is perfect for home overnight charging.

this is 100% correcct - I"m simply adding North American data for those playing along at home

• 3 phase power is NOT a thing for residential power in North America
• I'm unaware of _ANY_ 3-phase EVSE's available for purchase on the North American EVSE market - so it's all residential 240V devices.
• 240 volt single-phase AC power on 2x120V "power sources" are the 99.999999% rule for residential power
• "Mobile" EVSE's in north america can range in power from 1.44 kW to 9.6 kW (120V @ 12 amps to 240V @ 40 amps)
  • this both depends on the type of EVSE being used and the NEMA plug socket you're plugging into
  • NEMA sockets and their power ratings are a whole "thing" unto themselves that I'll spare the details here…but if you care/have questions there are plently of thread in Taycan forum.
  • 9.6 kW (240V @ 40 amps on a 50 amp breaker) is MAX power for _ANY_ North American EVSE - charge rates > 9.6 kW require a hard-wired non-mobile EVSE.
• 11 kw or greater charge rates require a "hardwired" non-Mobile EVSE
  • range of charge rate then is 11 kw - 19.2 kW (22 kW is NOT a thing in North American)
  • 11 kw is 240V @ 48 amps - 60 amp circuit breaker
  • 19.2 kw is 240V @ 80 amps - 100 amp circuit breaker
• North American electrical codes require EVSE circuits to have a breaker that is 25% larger than charging current
  • 12 amp charge rate requires a 15 amp breaker
  • 24 amp charge rate requires a 30 amp breaker
  • etc…
  • 80 amp charge rate (19.2 kW) requies a 100 amp breaker
• 19.2 kW/22 kW public L2 AC chargers are a very very very very rare bird in North America and generally not a thing
  • 19.2 kW charging option is therefore only useful if…
    • you have a 100/80 amp EVSE in your home (unlikely)
    • you have access to a 100/80 amp EVSE at work or business you frequent
• the most common charge rate for public L2 AC EVSE's in North America are 3.6-7.2 kW - even public 40 amp 9.6 kW EVSE's are fairly rare vs. common 6 kW public EVSE's
• growth is not happening in the public L2 AC charging infrastructure (beyond nominal 4-9 kW units) - fastDC charging is where all the investment is happening
  • there is no growth in more 19.2 kW EVSE's being "installed" over time - in fact it's likely to shrink - as older 19.2 kW EVSE's fall into normal maintenance cycles they are unlikely to be repaired, but might be replaced with a slower unit
  • 19.2 kW public EVSE infrastructure is not a "growth" market in North America.

based on all above even _IF_ the 19.2 kW charger was available as an option for Macan I'd be hard pressed to recommend it because it's very very unlikely your Macan/Taycan will ever encounter a 19.2 kW EVSE in it's entire life in North America - unless you install one yourself in your personal residence(s).

you're not missing out on anything - it's nice, it's fast, it's better - but it's sooooo uncommon you're unlikely to _EVER_ benefit from it in North America.

Appreciate that.

Not common in UK residential either due to cost but prevalent in rural and business settings.
