An EVSE is a power cord attached to a safety switch.

I'm in uk.
Have spent the last 20 mins going over some of these links. A massive thanks to you. Wish I'd known all of this before i jumped to EV.
Bought my first Taycan CT j1.2 2 weeks ago.
Test drove one 9 months ago. Sales guy told me you can charge up to 22kwh at home.
We have a 3 phase power supply, so this was appealing. It has potential to fully charge my car in 5 hours as opposed to 10 hours for standard 11kwh.
Why is that an advantage? Well, local weather means using more power in the car. It's cold and wet for at least 6 months of the year and car heating is required. Also, standard charge for electricity at home is £0.27 per kwh. Some power companies have off peak times from 23.30-05.00 with a rate of £0.07 per kwh. Public fast dc outlets are generally £0.75 per kwh.
So, you see the benefit of having a full charge in 5.5 hours at a 10th of the cost of public ev.
So, i get an Andersen A2 outlet at my home. £2.5k to fit. Does 22kwh. It's Porsche preferred supplier.
Anyways, i test drive my present car j1.2 taycan ct 4s, still love it, sales guy confirms i can charge in half the time because i have 3 phase.
Gets it home. Puzzled why it maxed out at 10.9kwh. Sales guy on holiday.
Texts my Andersen box guy. He says 22kwh charger on porsche is an "optional upgrade".
I can't find one. He sends a link. Turns out only j1 taycans can have it and it's £5k!
Thoroughly annoyed at lack of proper info from sales guy. Should never trust them.
Anyways, thanks again for your past posts. If i'd known, i could have saved £1.2k on an outlet.

Macan is really max 9.6, not 11 (minus the usual loss rate)?

correct…

 

[Jonathan S.]

correct…

That is bizarrely lame how a car that expensive can’t take full advantage of a standard hard-wired home setup.

yeah - Porsche even listed the car w/11 kW onboard charger for months as part of standard equipment…

this thread documents the discovery and Porsche's silence on the topic…

https://www.macanevowners.com/forum...ate-using-tesla-universal-wall-charger.18123/

they have now official downgraded it to 9.6 kW - but in Europe it works at 11 kW

 

[Jonathan S.]

Why would Porsche cheap out on that for the U.S. market?
It’s not like 11kW charger is some sort of advanced feature for an EV. I think almost all EV models have 11kW chargers?

I agree 100% and have no clue - they are simply infuriating sometimes…

I highly doubt it's actually a different part number or even a different component vs. the ROW - the only speculation I've seen that makes any sense is 11 kW in EU is 3-phase AC power at 16 amps (48 amps total) - but North America's single phase 240 is a full 48 amp on a single phase - perhaps their sh*tty OBC design has issue when run at/near max capacity - we know the 19.2 kW OBC has tons of problems and it has to do with component failure due to power flow issues…

perhaps the same issue with OBC in North America due to our single phase 240V AC power?

someone knows, but not me

I think it's one of two reasons:

1. component limit see above
2. confusion between mobile charger limit and OBC limit - we know PCNA has this conceptual block on the two different "limits" - and some how this confusion made it into the car's "confugraiton profile" - I'm pretty sure the limit could be "coded out/changed" if you were sufficiently motivated and had someone who could poke around with a PWIS…

The original option for 22kW on J1.1 was $1,200 if ordered from the factory. £5k sounds like the aftermarket retrofit. Then again, if you only need it at home, at that price you could look for a actual charger, i.e. ~20kW 3 phase DC charger. Those are usually meant for businesses, but could be installed at home as well, especially if you have 3 phase available. Maybe guilt the dealer into buying you one?

Thanks for the reply. I didn't know there was such a thing as a home dc charger! Will investigate

IIRC 11kW in Europe requires 3 phase (max 7kW on single phase) - European owners can jump in to correct or confirm. US is single phase only. Even when VWAG had the 22kW option, that is only 3-phase, in US it maxes out at 19.2kW on a single phase (I have two of those in my garage). So it would make sense that they followed the same strategy, make an 11kW 3-phase charger for Europe, sell it as 9.6kW in USA (notice those are exactly half of the 22kW/19.2kW numbers).

I am not very familiar with options for those, quick google gave me something like this (this one is a bit beefier, 30kW, but I have seen lower powered ones cheaper):
https://cyberswitching.com/product/dc-fast-charging-station-level-3-ev-charging-station-480v
There was another one mentioned here a little while back, which even had a fancy configurator for options including colors, cable length, etc, but I cannot find it at the moment.

Wow, a helluva price! Thanks for posting tho.

22kwh charger on porsche is an "optional upgrade".

You are better off without it. The failure rate on the J.1 Taycan 22kW onboard chargers was quite high, and when they fail they kill ALL charging and sometimes the car, which then requires towing. (Happened to mine and several others on here.)

Perhaps learning from this experience, plus the very low numbers of people in Europe who have 3-phase power at home, Porsche dropped the option from the J1.2 Taycan.
