22kw option for UK

[Sidicks]

I try and charge 50kW DC minimum on trips but broken CCS connectors or a lack of chargers (remoteness or somebody using the DC charger) makes 22kW AC a helpful backup.

You can use Zap-Map (or other apps) to determine charger type, a CCS connection means it is DC (50, 125, 150kW etc) and if the unit also has a 43kW Type 2 connection (popular standard a number of years ago) then it can also deliver AC at 22kW (or Taycan standard AC of 11kW).

There are many standalone 22kW AC only units too, these are obvious in Zap-Map, all are Type 2 connections.

Many thanks, that makes me reconsider whether I should have the 22kw AC upgrade. We are still investigating the cost of having 3-phase in our new garage, as there appears to already be a 3-phase supply to the house, not currently being used.

For home charging it won't be necessary, as I will typically be charging overnight (and my daily commute is relatively short), however when charging multiple cars then I guess this could be beneficial.

All depends on your own circumstance. I have 3ph at work and have a 3ph feed coming into my house into a 1ph meter providing 1ph for the house so to upgrade to 3ph would be relatively more simple and cheaper than most other people in the UK.

I still left the 22kw option off. Apart from not seeing that many public 22kw charging in London. My daily is a work van. Overnight charging at 7kw is more than enough for me. MFG have recently opened their 150kw charging station that is 5 mins away.

Afternoon all,


I appreciate this has been covered a number of times but i'd appreciate a quick, concise view on whether to tick the 22kw box when i order my GTS this week. Its expensive and for what i see, there isnt many chargers around the network. Will deff tick the 150kw option.

Personally, I would caution against ticking that box (you will also need to tick the Porsche Mobile Charger Connect box (or source another 22kW EVSE) and install 3 phase electric at home if you want to maximise the benefit. If you do the sums you'll likely find that the economics just don't stack up and it really depends on your starting point i.e. if you already have 3 phase supply then the option becomes a tempter.

There are many 22kW charging locations out there (ChargePlace Scotland has them littered everywhere currently - check their map and also check ZapMap ensuring you have the filters set correctly) - I was at the Old Course, St. Andrews yesterday and there were at least 10 x 22kW AC units scattered about in the car park alone.

Ideally you always want to target DC charging locations (speed of charging) but if these are limited in your locale then there could be merit in having the 22kW AC onboard option.

As for the 150kW DC 400V booster (they call it a charger but its a voltage booster hence the low cost) certainly worth having but in 14 months I've never come across a 400V DC unit >= 50kW so its never come into play (yet). They do exist and we expect access to Tesla's network (taking ages) but chances are you may not encounter on you regular charging route.

If DC is available where you regularly charge and you don't have 3 phase at home then I would skip this option. If you do have 3 phase at home then remember that the default AC onboard charger is 11kW which requires 3 phase to utilise fully and so you will get a boost by default.

What will you use to charge at home? If its a normal single phase 7kW supply like most in Ireland and UK have – then – according to that notice – you could damage the 22kW charger – or reduce its lifespan – if you don't or can't reduce your power to 6kW at home.

I am on my third 22kW charger.

Thanks for your note,

I dont have 3 phase @ home and dont intend to. The closest charge points to me are 22kw. Seems to be quite a number of them in the Glasgow area. I suppose i dont want to be caught out if the regular chargers are broken which seems to be a common theme.

I see this on the configuration although I’m not entirely sure what it means. There’s chargers near me at a local library. 1x 50kw & 1x 22kw.
Is there something else I need to check?

This warning / guidance has been poorly communicate by Porsche but in essence if you only charge at public 22kW AC locations and have the 22kW AC onboard charger option then nothing to worry about BUT if you don't have 3 phase supply at home (to give you 22kW) and have the 22kW AC onboard charger installed then the advice is to configure your home EVSE to limit electrical supply to 7kW (or thereabouts) as it appears to shorten the life of the charger (@tigerbalm has had several bad experiences with his 22kW AC onboard charger in less than 1 year of ownership).

 

[Fish Fingers]

Final plus point is that there are still lots of free 22kW chargers around. There is one where I walk my dogs so after a couple of hours of fresh air I can fill 50% of the battery.

Just don't tell your friends that you got charged while you were out dogging.

You can still use a 22kW AC Public charger without issue even if you don't upgrade the standard 11kW AC onboard charger in the car - perhaps that's the confusion?

If that's the reason then you don't need the option IMHO.

Absolutley,

To be clear, if i upgrade to 22kw and use my home 7kw to charge it will damage it?
If i keep the standard onboard 11kw charger and use the 22kw, its fine?
What cables do i then need to spec to be sure i cover all options?

Thank you all. Most helpful.

No it won't damage it as long as you adjust the current (default Amps - 32A = 7.4kW (approx)) of your EVSE at home to restrict to 6kW (25A, approx) as per the guidance given from Porsche. It may be that you can't get precisely 6kW but again don't get hung up on it.

Remember too that you get a 3 year warranty on the parts so no need to overthink this. Speak to your dealer for further assurance.

The standard onboard AC charger is rated to a max 11kW (i.e. it can handle this amount). Any public AC charger which offers less or greater than this amount can be used safely (there is no need even to think / check / consider) as the car will negotiate with the EVSE how much power it can consume and throttle down / up accordingly.

Cable wise: Standard EVSE (charger) supplied is the Porsche Mobile Charger Plus and is supplied with 2 supply cables and one cable to connect the EVSE to your car. The basic supply cable is the 13A 3-pin plug (same as your kettle, tv etc) but do not use this as you will get glacial charging speeds - emergency use only and if you take your charger with you on weekends on a 'just in case' basis. The second (and preferred) supply cable is the 32A for an industrial type socket) and will support up to 7.4kW (single phase). Be sure to get an electrician to do the supply from from your fuse box to where your EVSE will be located and they will install the correct socket.

For untethered (no EVSE to car cable) public AC connections (there are many) you should also option the Public Mode 3 cable and store this in the hidden storage area in the boot - you may never need it but....

All public DC chargers are 'tethered' and you simply use the CCS connector / cable provided at the EVSE.

From what I understand from your use case(s) I can't see a strong case for paying a premium for the 22kW AC onboard charger option. I don't have it nor have I ever felt I wished I had nor have I ordered it on my GTS ST.

 

[psglas]

If you're happy charging at 11kW on the 22kW public chargers then don't tick the box. It's a ridiculous price to pay for something you get included on a Renault Zoe. I just added it for the convenience of getting the full charge rate on a 22kW public unit as I got caught out with my last Taycan a couple of times when I needed a faster charge on 22kW.

For Scotland, I find it useful even although I don't have 3 phase at home. I didn't have it on my original 4S but speced it on the CT4. I often visit east dunbartonshire and some other council areas where they seem to have more 22kW options than DC. At least you know if you can't get a working DC charger you'll likely find a 22kW.

I see lots of broken chargers where I visit. About 50% of the points were broken in Helensburgh today, so I'd rather keep my options open. I can only see availability of public chargers getting worse, I'm afraid.

100% my reasoning, especially spending more and more time in Scotland. Hope this girlfriend works out as i seem to be working my self further north each time, I’ll be parking the Taycan outside an Igloo next…

I know what you are saying ?

Need to go fishing further and further afield where they don't know your reputation.

Due to existing infrastructure, it looks like we can have a 3-phase supply in the new garage fairly cheaply, so I will probably order the onboard 22kw charger.

Now, thanks to useful information provided by @W1NGE, I understand that the car will come with two cables:
- one which will allow to plug into a basic 3-pin socket for charging at other residential houses (at a glacial pace)
- one which will allow me to obtain the full 22kw charge speed from my 3-phase supply.

I just need my garage to have the appropriate 32amp socket to plug into.

Now, if I'm planning ahead when potentially my wife will also have an electronic car, can I assume that most other cars will also have an EVSE (and hence would also plug directly into this socket). Or might she need a separate EVSE for her car?

I'm still confused!

The EVSE used is typically agnostic to the vehicle and the cable from the EVSE to the car is standard. The trick is to not enable fancy features (if there are any) on the EVSE to control charging session and simply rely on the provided app (or within the car PCM / equivalent) - My Porsche and whatever else you might have in the future.

Note that you'll need to upgrade the standard EVSE you get with your Taycan to either the PMCC (if you want that) or another brand which can handle the full 19.6kW (22kW) available on 3 phase PLUS you will need to add the 22kW AC onboard charger option to your car(s).

If you stick with the PMC+ then you will get 11kW (requires 3 phase) with a PMCC or 9.6kW with a PMC+ which will be a wee bit better than the 7.4kW you would get on a single phase with either EVSE.

The one EVSE could serve one or more vehicles (different brands) OR you could add a secondary EVSE which (I think) will share the available 3 phase supply if both cars are charging at the same time (i.e. up to 11 kW per vehicle). I'm not an expert on electrics so please discuss with a qualified electrician to better understand the 'possible' rather than the 'maybe'.

In terms of supply cable needed (again seek expert guidance) you will likely need to upgrade to the 400V, 32A, 5 pin RED industrial connector as the standard one you get with the car is 230V, 32A, 5 pin - half the throughput, meaning that you would not get the full benefit of your 3 phase (assuming all of the above requirements are met).

Yep, it will damage it (22kw on 7kW) based on current feedback form owners and Porsche "guidance" aka small print. Knowing all this I've still ordered it, the benefit to me on the move is far more than the hit at home (and I don't to a daily commute that would leave me at low SoC, but do do a lot of long trips and plan some far flung destinations).

I had Andersen limit my home charging unit to 24A (its an older model so 25A not an option). My rental ID3 is charging at 5.4kW now so know its all sorted. I'd still occasionally use a 7kW destination charger without much worry but not use it daily at home at that speed. Some seem to feel Porsche may be implementing something soon (perhaps a limit from the car end).
