Porsche Wall Charger Connect (Order/Receive time?)

[JDNEPA]

I have an electrician due to my house next weekend (Saturday) to do the install. Thankfully, my house can support up to the 100 amp circuit and he'll be running the wire from the box to the garage and doing full install to breaker box, etc.

My plan was to just go for the Porsche Mobile Connect that comes with my car. It requires a 14-50 NEMA plug setup on a 50amp circuit. He's going to have the 100 amps ready to go should we want/need to add a 2nd 14-50 NEMA plug or move to hardwiring a 48v or up to the big 19.2 kw-22kw charger.

My issue - my Taycan doesn't have the 19.2kw onboard charger on it. I know this just got announced that it could be retro fitted, and I may do that but not right this second. My garage is closed and charging at night not an issue. Round trip to work is 20 miles there/back (40 miles total).

....I am now having second thoughts and just thinking I should have the electrician hardwire a Porsche Wall Connect on the full 80 amps. Get that setup up and I think my car should take advantage of the 11 kw/hr charge rate and if I upgraded, it's just an upgrade in the car and I'm at 19.6 kw.

Any advice here? ...for those that ordered the Porsche Wall Connect, how long did it take to ship and get to you (to the United States)? In check out, it has zero information about ship times and curious if it'd even get to me to be hardwired next week if I place the order today. Any experiences on order to receive times for those that ordered would be appreciated..... Car comes home this coming week (NLT Saturday - 7 days)

IMO there is no real reason for the 19.2 kW chargers. As a current Tesla driver I switched from hardwired 48A to 32A via mobile connector and nema 14-50. My daily driving of ~50 miles takes 2.5 hours to recharge instead of 1.75. But it all happens when I’m asleep, have never noticed the difference. Think about how many times you’ll be driving > 150 mi In a day AND end up at home AND not have 8 hours asleep at night before you need to go back out.

Btw I plan on keeping the nema 14-50 and using the PMCC for both taycan and Tesla, alternating nights which is plugged in.

 

[JDNEPA]

...that data point helps. My initial thought was just going with a 14-50, 50amp circuit. ...its just so easy given the electricians coming to start looking at 48v chargers... (hardwired req'd)...then if I was gonna do that, why not just go to the max and be done with it. Starting to feel like electrons are addictive gateway drugs.

...based on your input, I'd probably just keep the plan for the 14-50 and scale up later if I felt so compelled.

Unrelated to chargers. Which do you like more, your Tesla or your Taycan. My 9 y/o told me she wished I bought a Tesla over a Taycan Turbo S b/c it comes with video games. ...argh. Clearly our value systems diverge on priorities but curious since you have both.....

There is no real reason? Why are people so absolute about this? ?

There are plenty of “real” reasons. They just don’t apply to everyone.

OP’s use case doesn’t seem like it makes sense. But I would still put in the 100A circuit and box to the garage and run the 14-50R off of that.

@JDNEPA the car comes with PMC+ (Mobile charge plus) standard, not the PMCC (mobile charger connect). Did you option the PMCC?

 

[JDNEPA]

@Jhenson29 - My car optioned up and comes with the PMCC (mobile charger connect).

Regardless of where I go with this, I will have the 120 amp wired to the garage with the electrical sub panel in the garage so to your point, it'll be simpler should I hardwire in up to 60amp or end up purchasing later to the full 80amp option(s) then all subsequent work is isolated to the garage. I just wasn't sure how fast the wall charger would ship and could I get it to my electrician this weekend (7 days from now) should I order based on others' experiences. If not, it's money I'd spend, more logistics and I'd probably start with PMCC to begin anyway (otherwise I'd have to have him come back and I'd be in limbo from car pick up to whenever I got him back (likely at least another week later). Most of the decision making was timing/sequencing and just how much I may feel I need to bump up on charge times to 11 kw/h.

Replace “real” with “practical”. I outlined the one scenario I am aware of that it could be useful, which I’d expect to happen once a year +/- .

and if you need to you are probably close to a fast charger.

I’d love to hear a good use case for the 19.2 kw instead of just poking at my word choice.

for the OP, totally agree with running 100-120A to a sub panel in the garage. You can go up in power or have two outlets and not have to worry about the EVSEs talking to eachother for power share like Tesla or the Porsche home energy manager.

 

[JDNEPA]

@bergs - thanks. Aligned on the strategy. I'll hold off on ordering and plan to add later if I really want or feel the need later based on the 2 opinions provided - reinforced my initial plan....

 

[Jhenson29]

how much I may feel I need to bump up on charge times to 11 kw/h

There’s about a 50 min difference between the 9..6 and 11kW when charging from 25% to 85%. About 5.5 hours vs 4.75 hours.

But the car gets between 2.4 and 3.6 miles per kWh. Even on the low end of efficiency, you’ll only use around 20% SoC for a 40 mile round trip with a charging time difference of around 15 minutes between the two powers.

 

[JDNEPA]

@Jhenson29 - thanks. That's nothing and I'd prefer to keep the money for now. I'll have 10-12 hours to allow charging overnight M-F. Appreciate the info and help!!!

Nope.

Nope. I’m basically never close to a fast charger. It would always be an additional destination.

I’d love to hear a good use case for the 19.2 kw instead of just poking at my word choice.

I’m poking at your word choice because it’s very poor. If you had said something more like “most people” don’t need it, I wouldn’t have responded. But “no real reason” is simply too extreme of a statement.

My specific expected use case (the reason I got the 19.2kW) is lots of running around on weekends with stops at home in the middle of the day. It helps to be able to charge as fast as possible while at home for that stop.

And there are numerous unexpected use cases like this one:

well my taycan is still on a boat… but I rented a RWD with similar options last week. The taycan is way better all around, except for the zip. But on public roads it doesn’t really matter.
My 6yo loves the “driving games” on the Tesla. I’m keeping it as a nanny car

This debate keeps repeating itself - I do wish we could have a pinned / sticky thread to consolidate the pros and cons.

I have the PWCC 80A EVSE plus a CT4 with the 19.2kW AC charger option. My reasons:

• Fastest level 2 charging available, so that I have that maximum possible charging rate on the few occasions when I need it.
• Future proofing for larger capacity batteries.
• Turnaround in a heavy local driving day.
• Jump from charging profile 80% to 100% for short notice departure on a longer trip.
• Ability to sequentially service two or more EVs and do so in short order e.g. friends or family visiting in their own EV.
  

@JDNEPA Something to keep in mind - both the PMC+ and PMCC have problems with overheating when running at a full 40A. You might end up having to dial your PMCC down to 30A. The PWCC does not have this issue. Also, the PWCC is surprisingly reasonably priced. If you go for the PWCC on a 100A circuit, you’d be able to max out at 11kW on your current spec Taycan, and leave the option open for upgrading to 19.2kW later.

The prevailing advice for a 40A capable mobile EVSE is to go with one of the non-OEM brands.

IIRC my PWCC shipped very quickly - online order direct from Porsche. I think it came in 2 days.

I really hope your cat doesn’t get a UTI more than once a year….

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.
