AC charging

Not on a 3 phase supply, he would get up to 11kW. On 3 phase it isn't a simple P=IV. 400v at 16a 3 phase supply will provide 11kW. Hence why you'll get 22kW on a 32a 3 phase supply.

If the cable used was a 16a 3 phase cable, he'll get 11kW.

In truth we are all guessing here given the lack of accurate base data.

My assertions are based on using the standard supplied 32A 3 phase cable rather than a substitute.

If a donor cable was used then the doors are wide open to even more guesswork.

A 16A cable will be restricted to single phase therefore a charge rate of 10.4kW would not be possible
- 3.7kW more likely).
The cable would be further limited to 240v.

A 32A single phase cable could also have been used which would support up to 7.4kW. The cable would be further limited to 240v.

Similarly it could have been a 3 phase cable of either 16A or 32A which would support up to 11kW or up to 22kW respectively.

To keep things simple I've gone for the most likely outcome to explain to the OP.

16A 1 phase = 3.7kW
25A 1 phase = 7kW
16A 3 phase = 17kW (needs 3 phase cable + 21kW charger upgrade)
25A 3 phase = 21kW (needs 3 phase cable + 21kW charger upgrade)

most homes are 3 phase 16A and you’ll pay premium for 25A or 32A 3 phase utility connection.

Possibly where you are. Definitely not the case in the UK. The vast majority of homes are on single phase connections here. Usually between 60A and 80A supply, unless it’s been upgraded or is a very large house. Three phase is quite rare for domestic premises here.

This is in the Netherlands. I don’t know how it works in UK.

That was the impression of your comment though. The OP is in London and this in the UK section. All good ?

If a donor cable was used

Amen

Nobody says he has used a different cable and probably it is the standard 11 Kw board charger.

It was just one suggestion of a helpful member to make sure the correct cable was used. And that was correct. Nothing more nothing less.

Totally overlooked there is an “UK section” my bad, apologies gents

Has anyone considered if the issue could be the cable? If not, it’s probably worth talking about for 4 pages.

Frank - they OWE you (for both items).

I am quite the cynic and would not be surprised if both items went 'walkies' - has happened with EVSEs and cables before.

I know that at least in Ireland – the tyre goo and the free public charging cable – were only included in MY23 builds recently as standard. Before that they were €55 and €350 options respectively.

@f1eng I've no use for the "free" official Porsche 32A 400V 3-phase cable that was included in my Turbo S. If you DM me details – happy to post it to you – to a good home!

Not in UK - most homes are single phase.

They are in France, not sure about elsewhere but certainly very rare in the UK.

When I lived in France I was surprised to see I had 3-phase and that the standing charge changed if you needed a higher power.
My (very old, country) house had been wired with the 3 phases unequally shared so if I tried to use the dishwasher and washing machine at the same time it often tripped out, even though other phases were taking no load.

I re-connected the wiring to balance it rather than pay for a higher current supply.

I am only familiar with the wiring cnventions of UK and France though.

I’d be interested in the 150kw dc as a retrofit. Anyone heard of that?

At the Norwegian online breakers 'yard' and Saturday afternoon on the spanners wearing thick rubber gloves ?

Looks like the part (9J1 915 539) new is around £3K otherwise. Porsche dealer could no doubt fit a new one, it would probably be a couple of hours labour.

[option cost when new looks cheap. Sorry.]

Those figures do not look correct at all!

I have three phase installed with max 22 kW on the PMCC. Car can only take 11 kW but Zoe could take 22 kW. Overall the house has some 63 amp three phase supply.

With three phase you will get 11 kW charge with 16 amp, not 17 kW. 400 volts square root of 3x 16 amps. = 11 kW.

And three phase with 32 amps will get you 22 kW.

 

[Raphie]

You’re right.
