Porsche Wall Charger Connect (Order/Receive time?)

[Jhenson29]

@JDNEPA If you do end up going with the hardwired PWCC, I would recommend you also get a receptacle installed for a backup. EVSEs can fail and it can take longer to swap out a hardwired unit (vs a plug-in one which you just...you know....unplug).

Thanks to everyone for their input. Lot of info and going to make some modifications to my plan and try to coordinate/make these adjustments today with the electrician. This was super helpful!

Good luck whatever you do @JDNEPA. If you do go with the PWCC, take a look at my unbox/install thread.

I'm already set up for a 60amp at this point (wire already purchased - just garage panel to wall box) so I went with a Wallbox 48 amp for now. I can upgrade to the PWCC fairly easily when I decide to update the car to 19.6kw onboard charger and wire would just be upgraded from the panel to the PWCC at a future date. This should get me maxed out on Saturday at 11 kw and maxed out with current equipment. Will assess from there upgrades.... Wallbox is shipped and tracking for delivery on Wednesday for this Saturday. Apparently they needed to get me an 200 amp panel for my garage so I got plenty of room and will also have the 14-50 NEMA as a back up - no issue and on its own breaker. .....plan is coming together.

Appreciate everyone's help!!

I think Tesla knows EVs better than Porsche. Their AC charger used to be 9.6 kW with an option for dual, which put the charge power at 19.2 kW. Their latest gen of onboard chargers for all vehicles tops out at 48A so 11.7 kW with 100 kWh battery. They dropped max ac current from 80A to 48A from gen2 to gen3 AC wall boxes, which matches their vehicle hardware spec.

Everyone can justify what they bought (of course), but the OP asked for advice. And got a mixed bag.

Tesla offered the 72A upgrade from 48A for a while, might still be available from a "secret menu". Until recently I had an 80A capable Tesla, it was useful couple times a year (outside of COVID years). I replaced it with an 80A capable Taycan a month and half ago. It was really useful once on my trip home (3,500 miles), kind of useful one other time on that trip, and very nice to have for the first month I had my Taycan at home where my Taycan didn't have its own place in the garage until I sold my Tesla, so I had to charge the Taycan from one of the Tesla chargers while blocking-in my wife's Tesla, so had to move it after charging. Having 80A almost halved the charging time, so I could move it much sooner, convenient.

Is 19.2KW needed for everyone? Of course not. Is it useful to some people? Sure. Is is useless for some other people? Of course. Is it nice to have? Absolutely. In the end you need to consider your usecases.

PS> Telsa model 3 RWD maxes out at 32A. It works for some people.

any EVSE (not the PWCC) plugged into the NEMA 14-50 plug will charge at 40 amps

I think you meant max 40A, as there are EVSE's only capable of lower currents (32A seem common, but I've seen 16A too).
