Charging at Home error

[W1NGE]

Probably for the same reason you call the DC converter you attach to your phone a “charger”. If it connects and leads to charging - it’s a charger. However, you’re absolutely right that the sloppy naming confuses people in the role the device plays when you start looking at details.

If you are referring to the 400v 150 kW DC option also then that's a voltage booster and not a converter. It simply boosts the voltage of the standard 400v 50kW DC charger to 800v to handle EVSEs of 150kW which are typically 400v.

Better to control the charging session with PCM profile and timers IMHO

It is not as difficult as you think particularly for the use case described.

For example:

1 profile set to 25% with preferred charging window 01:00 - 05:00.
1 daily timer set to 01::00 - 05:00, target charge 85%

I did exactly this… set the timer in the car as the same schedule on the charger (2m-6am) yet when I’ve just put the charger in a get the red light and charging error on the app.., assuming as OP said it will still charge but it def didn’t fix the error message

Disable all other timers which are not part of the PCM as this will conflict.

Your EVSE should be in 'dumb' mode and used only to supply power. The car controls everything else as the actual charger is in the car (not your wallbox / EVSE/ "charger").

As W1NGE says.
Just let the car sort it out and leave the 'charger' as dumb.

Thanks for the reply but being a newbie I don’t think there’s a way to put the Ohme into dumb mode…. Checking through the manuals now… thanks everyone for your help

I think that you can select ‘charge to max’ which removes any schedules. May be wrong as new to Ohme Home Pro but been playing around with it and my Tesla

Yes think you can select that from the charger itself so If I delsect any charging schedule and do that will the car not accept the charge until the time I have selected in the PCM ? Sorry for all the questions !

Just disable any programming that you have set on the Ohme - it is 100% not required - use My Porsche App (or the PCM) to configure both profiles and timers.

In time, consider switching to OVO for your energy and use their Charge Anytime app which talks directly to your car as if it were the My Porsche App - 1/3 the cost / kw at anytime of the day when demand is low - absolute winner! Slightly higher standing charge and you must have a smart meter installed.

Also, why not use the PMC+ that came with your car for providing juice to the car - no need to have another (in general)?

Ahhh we don’t have OVO energy in N.Ireland unfortunately ?… I have the 7kw Ohme at home with a tethered cable does the PMC+ not take a long time to charge from the home socket ?

that’s correct, 13amp plug in will take longer, don’t hold me to this but I think 13 amp is about 6miles per hour charging rate and a 7kw at 30/32amps will be in the 40 to 50 miles per hour charging rate….as said not set in stone as it depends on how much you house electrics and installation can give due to age/conditions of house electrics and how good the earthing is….in VERY basic layman’s terms.

Yes that’s exactly right and why I got the 7kw OHME charger installed… I will try this max setting on yeh charger and set the timers in the car and see what happens when I plug it in and see if the errors stop and just forget about the schedules in the actual Ohme unit.,, thanks everyone for the help ?… much appreciated. PS the taycan turbo s is awesome !

My home country!

The same supply that you have for your Ohme will suit any other EVSE including the PMC+.

If you have a single phase 32A fused supply directly from your mainboard to the outlet / receptacle then you'll have the max available - 7.4kW. The PMC+ will support 9.6kW (possibly upto 11kW - but you'd need a 3 phase supply for the latter).

PMC+ comes with 2 'tails' - 32A (industrial connector) and 13A (3 pin socket). The 13A tail is for dire emergencies when away in the wilds / off-grid but the 32A tail is the one you should connect to it and then plug straight into your socket where your Ohme is. Sorted.

If you are in any doubt whatsoever then consult an Electrician - it's a doddle.

13A - 3 pin = 0.1 mile / minute of range
32A - industrial connecter = 0.3 mile / minute of range i.e. 3 times faster and perfect for overnight / at home charging from say 20% to 85% charge.

Thanks so much…. Yes I’m a moron when it comes to this kind of stuff… changing a plug was about the height of my prowess and that’s not even needed anymore lol…. They have the Ohme charger straight off my meter box outside I’ll post a pic so not sure I can even do what you advised !

No problem.

Not sure what's behind the box but if it comes off you should see the socket but again an Electrician might be useful.

I'm hoping it's not hardwired.

Also worth pursuing the original option once you've figured how to disable any programming.

It is hard wired to a breaker located in the junction box, the Ohme Home Pro has the option of 5m or 8m tethered cable. So no option to use another charging device unless you get an electrical to remove the Ohme and install a commando socket which means you just removed a £1k Ohme install.
