Amazing thread, thank you. Wish this was around when I picked up my Taycan earlier this year, would have saved me a lot of research. Still learned a great deal.

Had a blow out minutes after installation of conduit and the 14-50 box into my garage due to sloppy work; fortunately the electrician was able to come right back and diagnosed a pin-hole as the culprit. Startled the crap out of me as it made a loud pop as I was cleaning up. If at all possible, I would recommend folks plug in and let the car charge and put load on the connection for several minutes before releasing the electrician in case this happens.

Glad I found this thread...it has helped with my wifey's new 2021 BMW X3e hybrid and charging it and that has been a good thing as I prepare for my Taycan experience and delivery next year in 2022. All good info and tips to make sure my 1st EV experience is as painless as possible. As many have said its likely not my last EV experience. Thanks a lot.

please tell us what you ended up doing - this is an internet forum and we’re all curious - one or two chargers? 100 amp sub-panel? or lowly NEMA 14-30 plug - vendor EVSE (BMW) or did you go another way?

you don’t have to post - but can’t leave us hanging - saying great thread it helped a lot - and then not summarize your setup. LOL

Not a charger, but my landlady just had all the electrical in my apartment rewired, pot lights added and all the power plug ports upgraded to new hardware. It is important to note the electrician who did the work is over 60 kilo-meters away. We thought we had tested everything and he left. Then three weeks ago I went to mount the TV over the fireplace only to find the new power outlet he added there DID NOT WORK. And the way things are I only was able get him yesterday, turn out he did not screw ONE wire down properly. But I had to wait three weeks to get a fix.

Make sure you test EVERY connection before the electrician leaves.

Excellent thread! Now I can have an informed discussion with my electrician. Thanks, Dave!

Quick view didn't show the exact option I'm going with so I'll briefly describe it here. As in one of the other posts I'm installing a 100AMP breaker on my main panel and running at line, approx 90' to my garage. I'm going for the AC fast charging and ordered the Porsche Wall Charger Connect: https://shop.porsche.com/us/en/porsc...roduct-details. To use it you need to specify the 19.2 kW On-Board Charger option for the Taycan.

1. 100AMP breaker, wiring to the garage, mount/connect the Porsche Wall charger Connect - $2500
2. Porsche Wall Charger Connect - $1586 plus shipping
3. 19.2 kW On-Board Charger option - $1680

So almost $6k to set up for AC fast charging. On the 80AMP setting, I should be able to AC fast charge from 0 - 100% in about 5 hours at home. Since I plan on buying my wife an EV (Probably a 2023 Macan) I'm hoping that this will, at least somewhat, future-proof me. At least 90% of my charging will be done at home.

this is a _GREAT_ setup - however rather than the Porsche charger - I’d recommend ClipperCreek HCS-80 - the reason is it has a “share2” feature - in the future you can add a 2nd ClipperCreek HCS-80 and charge both EV’s splitling the load of the single 80 amp breaker (64 amp charging capacity) while both cars are charging it would provide 32 amps to each vehicle - and if only one car is charging you’ll get the full 64 amps dedicated to the single EV charging

alternatively in the future you could also “add” a 2nd porsche charger and configure it for 50/40 amps - and just manually split the load (50 amp breaker for each separate charger)…

I would also consider a 100 amp charger (80 amps) that has a split load feature, but not aware off the top of my head of a 100 amp split load charger setup…

your planned setup is _GREAT_ for a single EV and you’ll love the fast charging speed.

Doesn't charging at 19.2kW/h require three-phase power? I appreciate his setup, but it looks like it will do the 9.6 kw/h.

Supported Networks from the installation manual. So it should support the fu ll 19.2KW charge rate (given you have that option installed in your Taycan). If you follow the link provided in the other post you can
download both the installation and user manual (links at the bottom of the page).

I may add a second charger in the future after we purchase my wife's EV. Or, by that time, maybe there will be other options available. I actually ordered the Porsche Charger figuring it would be a while, what with the chip and other issues. It arrived 4 days after I ordered it. So now I'll have my charger up and ready to go about 3-4 months before my car arrives, lol.

I understand what the car will take, but Wye 208v is three-phase power, and I believe it's required to get above 11 kw/h and residential neighborhoods are not typically fed 3-phase.

It's all in the noise (in my opinion). I work for an electrical utility and live in a place where I can have 3-phase brought in, but I'm going to charge overnight on a time-of-use (TOU) account. Charging faster than 9.6kw/h isn't an advantage I'd go through the trouble for.

gnop1950

Well, I'll let you know how it turns out. The Porsche NA rep assured me I will get the max 19.2kw so long as I had one of the required electrical networks, the 19.2kw Taycan option, and was able to support the 80A output (100AMP breaker). The NA dip switch settings show that even with the Wye 208v only two phases are used, but then I'm not an electrician. I do know that my house has split phase 240v, which I believe is pretty common. If I can remember, (car delivery is still 143 days out), I'll report back on the charging times and any issues I might have.

daveo4porsche

No in North America it only required 240V @ 100 amp breaker - 80 amp charge rate due to 20% buffers for continuous loads…I've had 19.2 kW charging for years - Tesla originally supported it via Optional dual chargers on the Model S.

240V * 80 amps = 19,200 watts or 19.2 kW

Visceral

That's really good to hear, especially if the system is only using two phases (might as well then be 240 split phase, which is wired into almost every house). I'll have to correct the friend that worked with me on charging choices.

Dr Chill

Seems like a waste of money to me. 2 50 amp circuits and 2 level 2 chargers for under $2000 is what I'd do. No need for faster home charging than that IMO.
