[Europe, Single phase 240v] Taycan Slow Charging

[Kaxtos]

Hi guys,
First post here, apologies if am posting in wrong section and thanks in advanced.

OK, here we go. FYI read like 10 posts before posting just need validation from owners.

So I received my Taycan on Wednesday and last night I said let me test the charging incase its slow.

Note: I asked my Porsche dealer like 10 times during the months I was waiting do I need an electrician to do anything to get better charging times and his answer was no its just a wall plug, it will change just fine.

Anyways to get the story short have been charging 11 hours and got only 30%, so you get my point its slow.

What I understood by reading the forums is that the higher the KW the faster the charge and KW is based on the Amps of the wall breaker.

Normal wall plugs in Cyprus are on a MCB 16C / 16amps (240v), so my Taycan charger is only showing my max that is 10 AMPS. (So my kW is like 1-2)

Called the dealer last night and he has no idea, he would call me today.

What am thinking of doing is bringing an electrician to do below:

1. Add a dedicated line from the House breaker (Central panel of the house, to the garage)
2. Add an MCB of 32 / 40 or even 50 Amps if i can go that high on a single phase, he needs to check my house load
3. The current cable is on a twin cable 2.5mm , so i dont think it can go higher than 24 amps , so new wiring.
4. This parts am not sure. In the charging box theirs 2 cable

• The 3phase cable (with blue tip) that I cant use, as the house is a single phase
• The normal house plug that am currently charging with --> Question what is the highest amp the normal plug can go?

IF you can provide any help that would be much appreciated

A wall plug charger is more for a emergency charge or a hybrid car in my opinion.
Just get a wall charger (tesla has very good ones and are not expensive).

I live in a remote place with old cables and I get 230v 20 amp with that. Single phase is good enough unless you sleep less than 8 hours.

To obtain the max output of 7.4kW from your single phase supply you will need a separate 32A supply from your main fuse box terminated in a 32A industrial receptacle.

Your Porsche Mobile Charger Plus will have been supplied with 2 electrical supply cables one of which will be an industrial connector (must be 32A too). If you use the 3 pin plug then you will limit supply and is only intended for emergency use.

If you don't have a 32A supply and use anything other than a 32A receptacle then you will never get the maximum through-put.

I think you get it. If you go from 10 amps to 32 amps, you will triple your charging rate and go from 30% to 90%. You will need to get an electrician to install a higher wattage circuit dedicated to EV charging.

The limitations will be:
- how many amps are available in your house for EV charging. A house I owned a few years ago had 240v at 60amps total capacity and I was able to get 32 amps at night. Your electrician can do a load calculation on your house.
- what selections you have in the EVSE: you can find these listed in the EVSE manual. EVSEs usually have selectable charging rates such as 10 amps, 20 amps, 30amp, but you need this information when planning the new circuit.

But when planning a new EV charging circuit, you should plan for the future when you may want faster charging. The key element when doing this is the wire size. Bigger wires means you can potentially charge faster by swapping out the EVSE and circuit breaker. Changing to a new EVSE is easy, but upgrading the wire size in the future can be very messy and expensive (cutting holes in walls, plastering and repainting) so I always recommend to friends they upgrade their wire size during the initial EVSE install even though their current EVSE might not support a higher amperage.

Only issue is the restriction of the country and the area that we live.
For single phase, the houses are 40Amps and no way the electricity authority would allow to increase , so the 32Amps is out of the question, wont leave enough Amps for the rest of the house.

I did read that if you replace the normal wall plug with an industrial connector (blue cable that come with the charger) charging will get a bit better. 20%~, even on same Amps

The electrician will come tomorrow, lets see what's the highest breaker he can add.


Side Note: Just installed solar panels, not sure if that will provide more KWs to the house and with the use of the Porsche Home Energy Manager, could give the Taycan more Kw when it's available - Any advice if anyone used it?

That's a pain.

Anything less than 32A will lead to halving your maximum possible charging throughput.

I'm sure our single phase supply in UK is the same as Cyprus as I was able to have an electrician run a dedicated spur from the main fuse board @ 32A and has caused no issue whilst the rest of the property is using power. Possible though that you are limited by power company / government regulation.

If you end up with 16A - 20A then that will be better but depending on your EVSE (I'm assuming you have the standard Porsche Mobile Charger Plus) you will only be able to set it to 50% (16A) or 100% (32A) which will give you ~ 3.7kW @ 16A and so it will take twice as long to charge to the same level as a full single phase flow @ 32A.

Adding solar into the mix will help but you will need a home energy manager (Porsche HEM) or similar to manage the supplies.

You don't need 32 amps. Cyprus isn't that big.

Just not a wall plug charger but a dedicated cable with a wall charger.

I use them for over 4 years now, with 3 cars. My home is also 40 amps. 16 is more than enough if you use it daily when you sleep.
