@sergeyb maybe you can speak to some of this with your Taycan
@ericsan13 the 15 Amp charging bit below might be of great interest below because it EXPLICTLY recommended by Porsche, in a TSB, for emergency use only
I'm been doing some reading and if anyone is interested in the EV Macan, you might want to do some research cause I learned a bit about the Taycan charging issues below
Good discussion on what's needed. I totally agree with this guy and said this earlier in this thread, if you believe in an electric future, you aint going to have one EV so if you got to upgrade, then plan for ALL your cars as EV. You don't want that electrician coming out twice.
Taycan - School Me On Home Charging - Thinking about a Taycan again and my head is swimming with all the charging lingo. Hoping someone can simplify it for my little ant brain. What do I need to get level 2 charging at home? An EVSE on a 220 line with 50 amps? Does Porsche sell the equipment...

Scary, dont buy cheap stuff, get industrial quality everything. There is a LOT of power flowing.

His companion pieces, all good reads and a ton of information in here
Porsche seems to be wising up - this is mostly across the board good excellent information and I agree with 99% of it - very interesting that Porsche is now recommending AGAINST using L1 charging with their charger for daily use or for more than 12 hours this is a huge step forward in educating...

So it appears the Porsche chargers had issue, wires not thick enough, and they aint cheap. This resulting in a
class action suit? But the good stuff is in the Porsche TSBs at the NHTSA site that the original threads reference

They recommend getting industrial strength plugs. Those Hubbell plugs are $135 on Amazon. and this bit
The “domestic” (125V) supply cable is provided for emergency use only, and should not be used by customers for daily home charging.
110V Charging is for emergency use only. The relatively high current (8A to 10A) loads household circuits and receptacles for an extremely long time with minimal charge gain.
The thread author goes into why and I agree 100%. I believe the code is something like if a circuit is on for 3 hours the draw can't be more than 80%, hence the 50 amp circuit for a 40 amp draw. A residential 15 amp plug cost >$6 at Home Depot. The point seems to be it can't handle the load, day in, day out for a measly 30 miles or so of range. Both PCNA and the author got a point.
Think about what draws power in your house. You got any 15 amp circuits pulling 12 amps for 12 hours/day? Any? The only thing I can think of is an electric furnace and that's not a plug but hardwired. Otherwise, nothing.
For anyone interested, those are good reads with WAY too much detail for my brain. And that's a problem. There are far too many chargers, far too many plugs, far too many types of circuits, and far too many headaches with everyone having a different issue from the easy, low hanging fruit, to service upgrades 😞 involving trenching and far, far more complicated. And think of the future, not just today. This is not ready for prime time. Using the Tesla standard is a start but they got a LONG way to go. And that class action lawsuit would seem to indicate something was rushed?
Will Porsche try to compete?
