Charging not possible. First time I’m ever charging.

[anonymouse]

"Charging not possible" generally (but not always) means the charging unit is not supplying power. For example I see that when my charger is avoiding supplying power in peak rate times.

You are right that the little 110V charger doesn't achieve much. In countries with 240V our chargers go 2x the speed so are quite usable for a road trip if you aren't going too far to the next charger and are staying for a decent time overnight. They are nicknamed "granny chargers" (in part) because the main use case is to top up while visiting granny before returning home

But in the US at half the power it's a frustrating experience. So as others say, get a higher power charger installed at home with a Type 2 cable, and look for a fast charger mid journey if you are going on a road trip.

I'm at a loss to explain how different the experience with the Porsche units is US vs UK but our units are just not good. A neighbor just had his "pigtail" updated to the ones with heat sensors (not sure if that was a UK recall). Plugged in and charged for 5 minutes until the unit faulted. Let it sit and it would resume charging after maybe 10 minutes and then fault again. Never an issue until the getting the new connector so the assumption is that the new cable with the thermal sensor is faulty and tripping way early. 50 amp circuit and a Hubble socket. You could be correct and it is a setting, but the car is a 2021 so the PMCC has probably been used and configured. Over here, when in doubt blame the Porsche EVSE.

I have the Porsche PMCC and have used it for nearly 5 years now. My installation is on 400 volt 3 phase. And it has performed flawlessly over the years. It can provide 22 kW but my Taycan can only take 11 kW. But BMW’s , Zoe etc have charged t full speed on that unit and it is a great piece of equipment. Never overheated or gave any other problems.

I guess the trouble for the US is that it is used on a single phase circuit and with more amps than 32 per phase. (which is the max it uses at 22 kW). I have never felt any heat in the cable or the unit when charging in my garage. Sure I can feel it is warmer than at idle but no more than a normal phone charger.

I do not believe that the US version is any different from what I have, but Porsche probably never thought that it would work at more than 32 amp per phase. I believe it is just a bad overall design in the cabling

You are probably quite correct. Most PMC+ and PMCCs are connected to 50 or 60 amp circuits in the typical U.S. garage. Prior to Porsche recalling the charging pigtails and substituting new ones with thermal sensors (and I believe larger gauge wiring) their solution was to cripple their EVSEs to 50% of max. The only way to get 11 kWs into the car in the U.S. is on a 60 amp circuit. Were they really that clueless about the U.S. electrical standards?

Thanks for all the replies guys. I changed the amps from 6 to 8 with the configuration on the charger. That did the trick. I got about 20 miles of range for that overnight charge. Obv not ideal but I needed a quick top off as I never charged the car yet. I will be looking into the emporia level 2 charger as recommended. I have an electrician that has done a few of these installs in people’s homes by me.

Is the consensus to use public chargers when possible like electrify America over any at home chargers?

Yes, I was going to say, all you need to do is up the amps to 8. It is a good emergency charger when 120 is all you have. And no, the best solution is a Level 2 home EVSE, 240V with 32 Amps minimum. That will do the trick overnight and is easy on the battery. You can use your $1200 Porsche one, or another plug-in one, as long as you have good quality 14-50 plug (Hubbell or Bryant, $80-$100). Even better is to hardwire a third party box. Grizzl-e, Chargepoint Flex, Evoria, Wallbox are good.

This is the one correct? Thanks

That's the kind.

However, why are you opposed to the directly wired EVSE to get max 48Amp/11kW to the car. Socket based setup will be 40Amp/9.6kW max, which is not a lot of loss but so much more wiring, for what exact benefit.

Yes. I want to make sure you understand that it’s much more though - 1) panel has capacity and a spare 240 slot, 2) AWG 6 THHN wiring from your panel to the receptacle, 3) a 50Amp GCFI breaker, 4) a licensed electrician installing all that.

He can save $500 and use the PMCC he already paid for, although I know you don’t like that.

 

[Phix9000]

House is only 5 years old so should be up to code for all this. Pretty much every other house has an EV and a few taycans in the neighborhood as well. I have an electrician who’s done these installs for other people, but I’m not sure if he just buys some Home Depot off brand 14-50 outlet so I want to supply the correct one.

on the Hubble website they don’t seem to have any right now. Only selling Bryant. The Amazon reviews seem to say it’s a lot of fakes from China

thanks for all the advice

 

[SergeyIndy]

My direct wire was installed in no time by the electrician and for very low cost, since the copper is very short and goes directly from the panel behind the wall into the EVSE. No Hubble sockets or messy tubes and extra wires. 25ft cable can reach 2 cars parked next to each other.

I understand that and yes I prefer the clean setup like I have. $500 not worth of looking at a mess 100% of the time.

I have the same charger in US. It is great for me. I also initially had it set up with 120v power and got about 1kw charge speed and consistent warnings that stopped charging due to voltage fluctuations when other appliances started up ie air conditioner or dishwasher. When I installed a 240v outlet and used the 240v plug on the PMCC I no longer got any errors and charge at 9.6kw. I have not had a single issue with the charger, and since it’s Porsche brand it integrates nicely with the iOS app and I can see all my past and current charge sessions, etc. I would recommend the PMCC.

edit to say it is plugged in to a new 240v circuit, with new NEMA 15-40 outlet, 3x #6 feeders, and a 60A/2P breaker.

 

[BMonte13]

I use the same charger as the OP. I have a 22 RWD Taycan that I bought new in March of 2022. I had zero charging problems (I mostly charge at home given my solar panels that produce a lot) until a few months ago at 24K when I had the same "charging not possible error." I also btw have a Hubble outlet. I brought my vehicle in and it was fixed after a software upgrade documented here. Now at 28K miles and it's still charging beautifully at home.

No recall in UK and no parts replaced. Auto patching of software has been perfect too - in NA this was problematic and from memory I think throttled the output deliberately by 50%.

I've had mine since Nov 2020 and to date has been exemplary (runs at 32A which might be a differentiator) and is capable of delivering 22kW (I don't have 3 phase so don't achieve (or need) this level of power output).

Ok electrician coming Monday to install a Bryant 14-50 socket $450 cash.

he did my neighbors setup as well as many others around here.

also just had my calipers done figured I’d show them.
