Is the new 19.2 kW on board charger worth it?

[daveo4EV]

Hey @daveo4EV - from the other post you linked on the 19.2kw retrofit, I interpreted this as you chose not to do the retro fit and rather just upgrade your Taycan at some point down the road. My build is locked and I didn't chose the 19.2 option and wish I did.

too expensive for very limited use - so i decided to skip it - my main interest was plug&charge - but dealer estimate of $5k or more made me less interested

can you get 11kW if you do not have the 19.2 option but do have the capabilities at home? 80+ Amp circuit hardwired)

Yes, this is possible, just need a wall connect that supports that circuit. Any Wall Connect EVSE charger that is rated for a 60 Amp circuit will deliver the 11 kWh.

Yes you can but as mentioned it’s a fairly expensive option for what may be overnight charging anyway. It would then *just* charge at 11Kw or 40A 240v

I don’t think it’s a big deal it’s only for AC and you’ll probably never miss it. Unless you’re doing a ton of miles each day and remind almost exclusively on the home charger?

Yes, I’m pretty sure this is the default for Taycan.

Only possible on a hard wired circuit in the US (can’t get with plug-in AFAIK) with a minimum 60A fuse/48A power on 6AWG wire - this is what I have with a ChargePoint HomeFlex EVSE for last 1.5 yrs and always delivers 10.5 kW at car - you’ll never see full 11/11.5kW at the car due to normal equipment (cabling, heat etc) losses.

I think that’s what he was asking, 10.5kw~11kw. You get one or the other, depending on the option on the car, 11kw charging comes standard does it not? .

Yes 11kW std but not w/o a hard wired setup and was clarifying re you only need 60A fuse not 80A for a hard wired setup to access this.

 

[satchurator]

IMO it is worth it. See this post for a list of benefits of the 80A charging that this option enables.. Since writing that post, I wouldn't specifically advocate for the PWCC, but the 19.2kW onboard charger along with one of the few available 80A EVSEs has some notable benefits that matter to some people.

 

[Amelio]

Maybe it’s differentin Canada but for 11kw my electrician spec’d, a 50A breaker which is 20% larger than the supplied current of 40A to charger. 40x240 is 9.6kw in this setup. I’ve got 100A sub panel so I can play around with the configurations a little.

for 50A it would be a 60A breaker as you mentioned, you don’t get that much anyway. Hey, we’re splitting hairs here. What is kilowatt or two between friends?! ?

Thank you all for the info/feedback!
@ciaranob i too have the same ChargePoint homeFlex set up but they put it on an 80 amp when it was installed a while back. 10.5 will have to be good enough as I can’t change the build now!

[North America] - there is an overriding fact here - there simply are not that many 19.2 kW chargers "in the wild" - so basically if you get this option it will only be used with your personal home setup - also 19.2 kW commercial/public charger is not a "growth industry" (i.e. there is not a big push to install more of these - the push is FastDC chargers for which this option doens't matter).

so if you get this option and expect to help you in North America while traveling - you are likely be be sorely disappointed with only rare/occasional 100/80 amp chargers being available beyond your own home setup - and _IF_ you do find one it's likely to be a Tesla Destination charger at a business/hotel so you'll need a TeslaTap to access it.

it's a great feature if you have this at home, and it does charge the Taycan 2x faster than default 40/50 amp chargers - but for travel you mostly used FastDC chargers, or the L2/AC chargers you'll encounter you're lucky to find 6 kW (30 amp) chargers…

it's just not a thing in North America - so only get this option if you are going to install your own 100/80 amp EVSE - or you know for a fact you'll have access to 100/80 amp EVSE's in your normal routine.

it's a great option - charging faster is a good thing - so yeah it's good - but honestly and factually other than at home with your own EVSE you will not be able to find a lot of 100/80 amp 19.2 kW EVSE's in North America while traveling - and there are not more in your future - that is simply _NOT_ the trend.

so get it for your own personal charging and turn around time, but don't expect to benefit from it while traveling.

No.

You'll need to hire an electrician to install the PWCC, but refer to the following thread ahead of time so you know what is going on better than the electrician.

Porsche Wall Charger Connect | Unbox & Install

I'm very satisfied with the unit, but there remains an open question of whether it will charge a non-Porsche, non-Audi, non-VW EV to full charge. This has never been an issue for my Taycan, and the PWCC doesn't have the overheating issue on the cables of the PMCC.

Some posts in the above thread from last year stated that in some instances the PWCC would start charging a non-Porsche EV fine and then stop at some point for unclear reasons, leaving you without charge when you went out the car in the morning. My experience in charging a Tesla for 30 minutes produced no issues, but that isn't a full, overnight charge.

There is a new SW release for the PWCC and it may have changed some aspects of this, but I've been unable to test it.

Regardless of which EVSE you go with, I think the onboard Taycan 19.2 KW charger is a good investment.

No problem. i live in a condo and the Tesla car owners in my condo use my Porsche charger all the time with no problems using their adapter.The charging current is limited to 32 Amps

Wow! This is great to hear. There’s been uncertainty about whether the PWCC will handle other EVs. (You are talking about the PWCC not the PMCC, right?)

Thanks for sharing! ?
