AC charging

[Kev946]

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 live in France and most houses are 60A single phase. You go higher you must have 3 phase so there are a few bigger houses that use 3 phase. I've made the switch to 3 phase in advance of getting my new Taycan on order. On 3 phase you can go to 60A 3 phase so 3 times the max on single phase.

Just read a message on the Belgian site that some 22 Kw public chargers are set to deliver 11 Kw even if they are registered online to deliver 22 Kw.

This is becoming the world's biggest scam!

There’s a lot of wool you can pull over folks eyes if you’re lead to believe it’s just your battery too cold or is too full.

Sure they’re important factors but so is halving the amount of power you could ever hope to receive through power sharing / splitting arrangements.

It’s clearly very common practise and understood by those inside rhe “industry” but news to most ordinary punters.

were only included in MY23 builds recently as standard. Before that they were €55 and €350 options respectively.

Pretty shameless urine extraction going on there - charging for goo and not supplying an adequate charging cable as expensive options in a £100k electric car with no spare. Little wonder Porsche margins are so high!

I think this might be the charge providers stretching the issue.

where I Went the other day, there was a 22 kW charger with 2 outlets according to the Porsche charging planner. I t comes up in the map in the app and also in the car and as it was on a village parking site. Great for charging while having lunch at a nice restaurant I thought!

If it comes in the Porsche Planning in the map I assumed it would accept my Porsche app, but no Code to scan! And it would not open the hatch with the Porsche Charging card. The Porsche helpline was totally useless since they could not even find the charger and recommended a charger 5 km‘s away!

A Chargemap card opened the charger so I could plug in, but the charger only delivered 7.4 kW according to the sign on it and the car reported about 6.5 kW! At a price of 0.68 Euro per kWh! What a scam!

I would ask my Dealer (out of goodwill) - standard on MY22 cars onwards which yours will be, right?

I had to buy mine (MY21) and is 'free' on my MY23 GTS ST.

Interesting, is there any way to tell the 16A and 32A cables apart? eg colour etc? No idea what came with my 21 reg car, assuming from your post it sounds like a 16A was supplied to cars of that reg(black and short) although it was a late 71 car (Porsche described it as a 22MY) so really not sure! Right on the cusp.

I know I get 11kW on a 22kW three phase at work but had assumed that was due to someone not speccing the 22kW charger (although I don' know whether it was specced or not, is there any way to check that? eg options list sticker somewhere? Is there a code for 22kWAC?).

Perhaps I'll borrow the Mennekes from the Tesla and try that at work to see if it makes a difference.....

Incidentally, does the new J1.2 still have a 22kW option? Couldn't see it on the configurator.

There is colour coding (16A RED Commando, 32A BLUE Commando) however some manufacturers have ignored that and use the same colour for either rating or indeed go black which is not at all helpful.

The cable / connector should be marked however with relevant ratings.

In the early days when dealerships knew feck all about feck all pertaining to the Taycan it was possible to option either a 32A or 16A EVSE to car cable and if you didn't do your research you (as many did) may have purchased the wrong cable (16A) and then wondered (as did the inept dealership) why your car was charging even slower than you'd expected.

MY21 would have fallen into that category as the cable was an 'extra' (yes, indeed!).

From MY22 onwards an L2 Mode 3 32A cable and connector which shipped as standard thereby removing the decision and / or confusion.

So check the cable / cable socket to see if you can see any markings and that will be a clue.

Some unscrupulous dealerships even 'lost' or 'swapped' cables (and EVSEs) between cars.

What EVSE (charger - don't get me started on that as these are not chargers as the charger is physically in the car both AC and DC) do you have / referring to - the one you have with the car or the workplace?

Three phases are needed for either 11kW or 22kW so it depends on how the workplace unit is plumbed in and what rating the EVSE itself is. Hopefully it's all rated to 22kW but if an Accountant was involved there may have been some penny pinching.

3.7kW - 1 phase supply - 16A (0.15 mi/minute charge)
7.4kW - 1 phase supply - 32A (0.3 mi/minute charge)
11kW - 3 phase supply - 16A (0.6 mi/minute charge)
22kW - 3 phase supply - 32A (0.9 mi/minute charge)

From the fuse box to the wall socket to the EVSE to the cable to the car to the commando socket at either end they must all be rated to 32A - any reduction will make the entire end-to-end piece the same so if 16A cabling is in place then you will only get 16A, if the socket is 16A then the same again and so on.

My old Tesla gets 19kW from it at work so definitely full fat 22kW.

Hehe yes I'd long ago given up on EVSE but you're quite correct. Well winged!! ?

will go look carefully at the cable that came with the car later.
Cheers.

Definitely the car then. Not the cable.
Ho hum poor speccing by someone.

So you should get 10.4 - 10.6kW from your workplace EVSE then if it is 22kW which you've just confirmed that it is.

Standard Taycan onboard AC charger is 11kW but for a ridiculous £1,200 you could have got an unreliable 22kW option. Not many takers and to be honest is a waste of money given DC is preferred and 7.4kW for overnight charging (or anytime charging) is more than suitable for most.

The 22kW AC onboard charger may have been withdrawn by now - @tigerbalm consumed at least 4 of these puppies such was the reliability.

Yes it looks that way. Shame the 22 was poor - use it a lot here (work) and pretty much all on street charging in Germany (family) is 22.

yep gives 10.5 here at work.
?£1200 is crackers.

Mind you so was a 150kW DCDC ilo a series parallel switch.... ?

I also gather plug and charge didn't work if you had the 22 fitted and my screen definitely shows the P&C option so that confirms no 22kW charger fitted.

cheers for assistance.

The price is ridiculous YES!

But I find it quite useful to charge up relatively quickly with 3 phase. And I only have 11 kW in the Taycan. A loan BMW charged at 22 kW no problems, so the unit works well, at least for me.

And DC would not be an alternative at all since you have no way of controlling the charge level with Porsche implementation. That is the big message now for the ARB6 recall.

Porsche managed to make the whole charging settings the most complex and least functional one, for modern EV’s!
’Quite an achievement actually.

In the early 2020 Taycans PnC would not work at all with the std 11 kW charger. They had missed out something about a certificate in the unit band could not retrofit it!

No issue with plug&charge on the 22kW unit from MY21 onwards. I utilise it frequently at IONITY.
