Nonsense: there is no risk in being connected to 3-phases versus 1-phase, and the Jaguar engineers did not make any mistake in the AC charging setup. This is why: there is no way the i-Pace hardware or software could detect whether it is connected to 1 or 3 phases. Physically only phase 1 is connected (see the socket in the car inlet: the bottom two holes - those are for phase 2 and phase 3 on three-phase cars - don't have contact bushings at all, so 'sensing' presence of phase 2 and 3 is impossible). In addition, the charging protocol of Mode 3 charging (see IEC 61851-1) makes no distinction between 1 or 3 phases either. The protocol (=communication between car and charger) only controls the Amps. So there is no way the software could 'detect' whether it is connected to 1 or 3-phase. So there really should be no difference between being connected to a 1-phase 32A or a 3-phase 32A charger: in both cases you should get the same charging power/speed.

If you do see a difference: it is 100% the charger, not the i-Pace, that makes the difference.

What could be the case is that the 3-phase charger that you experienced slower charging at, as compared to the other 1-phase charger, is that the 3-phase charger could be equipped with load balancing/smart charging software, which limits the available amps if multiple cars are charging at the same charger cluster (e.g. charging stations with two sockets, charging plaza's etc.), and/or if the building that the charger is sharing the power grid connection with (e.g. residential home), is consuming a significant amount of power, that the charger Amps are limited by the smart charging software.
Well reality is that so far on all public 22kW chargers and I have tried multiple including the one at work very often that I am getting 3-4% instead of the expected 8-9% charge. At home I tracked it both on App (showing 7-11%) and in Excel over a long period and I am getting to 5.5kW average all the way to 100% so till 85% it was running slighly above 7kW and that is on a 1x 35A home connection.

So call it nonsense and I hope you are right but so far my experience is that there is certainly some truth to it!!!
My apologies for using the word ‘nonsense’, that is not a nice word I realize.
I just wanted to make clear that there is really no difference at all for the i-Pace between being connected to a 1 phase or a 3 phase supply. The i-Pace simply can not detect by any means whether a second and third phase are present or not. Not physically and not in the Mode 3 protocol between car and charger.

What you are experiencing is for 100% sure caused by the charger. If you don’t get 32A on a ‘22kW’ public charger, it is simply not supplying 32A but limited to a lower amperage. This is why: In the Netherlands Many ‘22kW’ chargers are listed in apps etc. as ‘22kW’ chargers, which in fact stands for: 3-phase 32A. The problem is that this in many cases refers to the network connection of the charger unit. And as most of the public ‘22kW’ chargers have two charging sockets, this network connection has to be shared between the two sockets. In The Netherlands a usual network connection is 3x35A. And if these chargers are not load balanced, and many still aren’t, this means that in reality those chargers do not supply 32A per socket, but 16A per socket so the total (incl some spare Amps for the contoller, RFID receiver, modem etc) will not exceed the 35A of the network connection. If a charger IS load balanced, and newer models are most of the times, it is possible to supply the full 32A to a single socket (of the two), only if the other socket is not in use. If a second EV is connected to the other socket however, the load balancing controller will reduce the power to socket A, so socket B will get a reasonable amount of power as well. Depending of how many Amps both EV’s are consuming the load balancer will distribute the total available 32A over both sockets as fair as possible. Result: less than 7kW to a single phase charging EV such as the i-Pace.
Your home charger does not have all the issues described above, except load balancing between the house power consumption and the charger power consumption, so the total will not exceed the 25A/35A/40A of your 3x25A or 1x35A/40A house grid connection. Effectively this means that at home you will be able to charge to the full available 32A (7kW) on your 1x35A/40A home power supply during the night when dryer, dish washer etc are finished with their tasks.
Hope this clarifies.

Blimey, seems you need a degree in electrical engineering to run an i-Pace! ;)

But it is not as difficult as it seems: the InControl Remote App should show how fast your i-Pace is charging.
And all charging apps should indicate the right amount of available charging power for each charging station. At the moment many of those apps don’t unfortunately.

I think this is the supplied cable.
This is how the UK Mode 2 Home Charging Cable that comes with the vehicle as standard looks:

For those in the UK that have this charging unit, is it waterproof? The label on the cable has a symbol that implies it isn't but the unit in the symbol looks different to the one supplied. The unit itself looks reasonably well made and as if it might be watertight?

It's like everything else is today. Once you get it set up, it becomes simple. Getting setup is complicated because it's new.
It stays simple until...

THEY CHANGE THE $^$%# OPERATING SYSTEM AND YOU HAVE TO LEARN EVERYTHING AGAIN FROM SCRATCH!!! :twisted:

Seriously, nearly all owners will do nearly all their charging at home. Remote charging at CCS stations is easy.
So once you get your "Smart" 32 amp or bigger L2 EVSE installed at home, you just do all your timed charging from the phone.

After using EVs since 2013, for me EVs are WAY easier to refuel than gas and especially diesel cars. I wake up each morning with a "full tank". No driving out of my way to a petrol station, waiting in line, fuel on my hands, fuel on the paint, people begging for money for drugs ("spare some money for gas so I can get home?" is really for booze or drugs), or worse of all, getting the wrong fuel either by the owner or the station with an expensive repair bill, warm up the car in the garage without dying of CO poisoning.

True, but I wouldn't entertain any EV but the i-Pace. ;)
But only when I can fully recharge in 5 minutes, like my F-Type. :D

10 mins to drive to the garage. If lucky then you can use a pump straight away, if not, hang on for 5 mins while the guy fills his car then goes and pay for it. He gets stuck in the queue waiting for someone who has done their daily shopping and is arguing with the till assistant because he wants to buy fags, but doesn’t look 25. He gives up with the fags and pays up for the shopping. There is quite a queue at the till now :-(

Finally you get to the till and they have run out of paper in the till so you wait a bit longer for them to change it. You eventually pay your £80.00 to get 300 miles in your car.

Getting back to your car you are blocked in by the guy in front, fortunately he doesn’t take long so you are on your way back home. 10 mins later you are home. That took around 30mins in all.

I got home last night and plugged my I-Pace in, took less than 1 minute to get the cable out and plug it in. It was fully charged in the morning and didn’t really take any time at all. As for cost.....

Of course, if you're charging during a long drive you'll have a lot longer to wait than that 30 minute worst case scenario you've invented. ;)
I get my gas en route from a shopping trip and at that time of day there are very few customers and the till has never run out of paper. :D

Wasn’t an invented scenario. Happened to me only yesterday when filling up my Range Rover, and not the first time something similar has happened.

I tend not to do long trips. I did go down to London to see Paul McCartney recently at the O2. We stayed at the Intercontinental that is linked to the O2. I gave the keys for the I-Pace to the concierge. In the morning he returned them to me with my car that had been fully charged overnight by the hotel at no cost to me. Can’t see them doing that with an ICE car :-)

Hi all,

New to the forum...

I have an I-PACE on order, due April, and my dealer is asking me if I want him to arrange a Home charger. Tempted by avoiding the hassle by letting him deal with it, but looking at Chargemaster reviews doesn’t fill me with confidence.

I don’t have self-generation, although might in the future. The Zappi unit gets good reviews, and I’m open to switching to an EV tariff if it saves money overall.

Would appreciate any guidance!
