Three phases means 400V…with fuse of 32A gives you 22kw.
Edited: this is wrong On 240V with 32A you can get 13kw per hour.

Sorry but your wrong 230v At 32amps =7.4kw , my company install s car chargers so we do no what we are talking about ?

i stand corrected… with one phase you can get 7,4kw only.
i’ve been thinking of three-phases, 400V too much….

Hi again,

I have an update. Today, it said ”Front left indicator faulty”. I took a video showing the proboem and contacted the seller and he sayd it needed reparation because one of the blinkers is faulty. The seller also stated that an ultrasound sensor may be broken and also needs reparation, and that’s why the interior survelliance keeps going off.
Really disappointed.
I will post more updates soon, when I know more.

Did you specify the 22kW AC charger on the car?

STD AC onboard charger is 11kW so if you don't have the above then the max you will get is 11kW.

The supply must be on a 32A fused supply and properly earthed (or higher) to your charging station.

Your charger should not be charging above 80% of the fuse/breaker value on the supply, hence 32A chargers require 40A supply, 40A chargers require 50A supply, 48A charger require 60A supply, etc.

with 32A you can get 22kw….or at least 13kw (at 240V).

No you cannot get 22KW with 32A on single phase 240V AC charging.
Power(W) = Current(A) * Voltage(V)
(for AC there is also a power factor involved, but for this topic you can ignore it)
so if you charger delivers 32A, that is 32A * 240V = 7,680W which is ~7.7KW

@Oysterquartz , is there a public L2 charger near you? If so, I'd suggest driving there and seeing whether your car will charge faster as expected from public L2 (not DC, as that is separate). If yes, you know you have an issue with your chargers at home, if not, the issue is on the car side (sorry, don't have a Taycan yet, so not intimately familiar with its settings, but from what I read here, there are no settings to slow the charging down).

I didn't think of this! I'm definitely trying this out tomorrow. I believe there are public L2 chargers close to me. Thank you!
There are no settings on the Taycan from what I know, have tried looking for it though.

@whitex : if you have seen, I already stand corrected.... I've been thinking & writing about three phases, 400V, which means 400V * 32A * 1,73 ... than I (mistakenly) left square root of 3 in calculation for 240V...

Touché! I replied before getting to that post.

So 32 amps on 240v gives you max 7.4kw , three phase 32 amp 11kw . If you have the on board 22kw option then three phase then the car can charge at 22kw . Hope this helps

Don't think that's correct. I have single phase - max 7.4kW

Correct - nothing to alter AC charging within the car. There is setting to restrict DC charging speed when using ultra fast charging points (350 (270kW) but that's not relevant here.

Have you tried charging at a public AC (type 2) charger and check the lower display in the Taycan for charging speed ? (If it shows km/min, click on it to see kWh). Doing this makes sure there is nothing wrong with the Taycan.
Are you sure the BMW charger is supplying 22kWh to the Taycan? (The maximum for an i3s seems to be 11kWh, maybe the charger has been limited even more?)

I have a smart meter at my home to which I have connected a Raspberry Pi. Together with the p1mon monitor program I can view the power usage per phase. When charging, I can "see" the 11 kWh flowing through my charger

Checked today and the supplying 1.9kw. Currently charging at a Public L2 charger, car is accepting the 3.7kw the L2 charger is supposed to give out. Calling an electrician soon for them to fix my equipment at home.

3.7 Sounds very low for a public AC charger ?
Maybe there is an 11kW or even 22kW nearby so you can rule out any problem in the Taycan ?
Note: Speed of charge depends on state of charge. You can expect the speed of charge to become lower when state of charge close to 100%, but there is more in play.

Sorry, my fault, forgot to say that I also tried a 22kw charger next to the 3.7 one. Had a 77% charge and the car accepted 13.76 kw.
