We are now a 2 EV family - a Leaf24 and now a nearly new ID4. The ID4 did not come with a 3pin charging cable and we’re toying over whether we need to buy one.

The leaf came with a 3pin but no Type2-Type1 so we had to buy one of those. Apart from a few early chargers before the wall charger, we’ve never used it but it sits in the boot in case of emergency.

Buying a granny charger for the ID4 seems like a waste but at the back of my mind is the possibility of needing to charge from a plain old socket (including perhaps convenience if away at a friends/holiday home). Am I being too pessimistic? With the big battery I should be able to manage right?

If I did buy one I was thinking about the 3 pin Ohme on the £199 deal - are there any advantages that I’d get in the rare occasions we’d use it?

It's only worthwhile if you plan on visiting people such as a "granny" who are so far away that you need to recharge and who doesn't have a charge point but will let you charge from a suitable outside plug. Given the range of the ID.4 and the risk of other people having suitable wiring I'd say no
But an alternative would be to buy an Ohme lead on a Commando plug and get them to de-rate it to 10A. You could them buy a short flylead to convert from 3 pin to Commando.

What would be the advantage of that over a 3 pin if I also have a home charger? In case I’m at a caravan site?

Thanks!

What's your Plan B if the wall-mounted EVSE a home breaks? Not unknown. If you have a load of free Podpoints at a shop nearby, or a Rapid at back of local pub, fine. Otherwise you might consider a "granny" backup just-in-case. You can get a cheap one from screwfix, which offers 10A only afaik, but you can set the ID.4 to low-charging rate which will limit itself to 6A rate, this is a good thing to do to avoid any risk of toasting someone else's 13A socket you're borrowing.

Or you can get something more versatile, e.g. see evconnectors.com where they have UK 13A or Commando-plug swappable "granny" EVSE that can be set to 6/8/10/13/16A. I have one of these, I bought just the 13A plug one as I don't go camping. After 3-4 years heavy use I strongly suggest you get it stripped, and all the high-current solder joints reflowed. This will increase the lifespan of it very greatly! And if it starts to wear out the relays used as contactors, these can be changed for new ones without too much bother, again increasing the lifespan hugely. You'll know the relays are going when it starts to trip due to internal overheating. Nicely made piece of kit, providing it's regularly serviced as I've described.

You could get a commando socket fitted at home and this would then charge EV at 16A happily, change to the 13A plug for your travels to granny. Sounds a bit like the Ohme mentioned above, but I have zero knowledge of those.

If you are interested in a granny charging cable I have one for sale in the Members Classifieds section. It‘s the one that VW sells with their ID3 and ID4.

You know I had this exact conversation the other morning! I drove my ID.4 up to Scotland over the weekend and was told the hotel had an EV chargepoint they would reserve for me. When I arrived (admittedly rather late on Friday night) with 15% battery I saw another ID.4 plugged into the 7 kW type 2 chargepoint... Fortunately I had my granny cable on me, and the chargepoint was one of those PodPoints with a type 2 and a 3-pin, so I just plugged into the 3-pin and got my family inside the hotel. The next morning I popped out and the owners of the other ID.4 were there - they were brand-new to EVs and didn't even know granny charging was possible, but they asked me all sorts of questions about mine and ended up buying one right on the spot!

I can't say that the granny charger has ever been 100% absolutely necessary for me (there were rapid chargers not too far from the hotel, but since we arrived at almost midnight it was much more convenient to just park and plug in there), but I will say I have been very glad of having the granny cable on multiple occasions. For another example, two weeks ago we did a long weekend in a lovely cottage in the Yorkshire Dales. The nearest public chargepoint was a 7 kW in the Aysgarth Falls car park maybe 15 minutes away, but I had messaged the cottage owner beforehand and he had no problem with us plugging into the socket in the garage. I did set my ID.4 to the "reduced AC charge" setting as I didn't know the socket, but I plugged in every night after doing our daily excursions and I really appreciated waking up with the extra range. Now the ID.4 has a big battery and I could have done that whole trip just using rapid charges on the way up/down (maybe stopping at the instavolt on our way back from the lake district), but having the granny cable in the car certainly made any range anxiety an absolute non-issue.

All that being said, I already had a 10m granny cable, since that was my only method of charging my Zoe before buying the ID.4 (and subsequently having a Zappi installed). So I didn't have to buy one "just in case". Though I probably would have anyway, because you never know when something crazy will happen and your only method of charging will be to knock on someone's door and ask to plug into an external 3-pin...

Only you know how much use you'll get out of it, but I wouldn't be without mine.

I take it when I'm staying with friends, and when camping. Often I do a rapid charge to 50 or 60% on the way in, and leave it on the granny to get to 100.

Usually I could survive without it, but getting to 100% is a nice bonus.

I bought a 3 pin charger (Chinese made?) and a thick garden extension cable.

The extension cable and it's wall plug got slightly warm but it worked.

Shall I alter the settings in the ID4 when I use this? There were a lot of numbers mentioned above - what would be a good setting?

Should I change amp setting on the cable box - or in the car? Or both?

(We have 2 x ID4's and are waiting for charge point instalation at our house.)

Thanks in advance

Will try to post photos.

As general advice, I would always say charge at the lowest rate you can get away with.

If you switch the slider on the ‘Reduced AC Charging Current’, that should take it under 10A/2kW, that most 3 pin sockets should cope with longer term.

On some charge units, you can reduce the rate further, something like 5A, not sure on your granny charger model though.

6A is the minimum rate possible. Quite a few do 6/8/10A, some even do 6/8/10/13/16A and have a swappable plug for Commando use, so as it happens can be set to draw 16A through the 13A plug! Not that I'd recommend this!

Heavily used granny EVSEs can & do wear out. I've had one such wear out twice; the first time after 4 years use the main relay inside was getting hot & triggering overheat tripping, so I swapped it out for a new relay. A year later the solder joint where mains goes onto the PCB failed dramatically, blew the PCB to bits & sent a spike down the control CP low-voltage wire that damaged my car's charge controller. Bill >£1000 to repair car, plus cost of new EVSE. Next time I'll redo the solder joints after 3 years use, whatever make of granny I happen to be using. These are not designed or intended for heavy, regular use, get a proper wall-mounted EVSE for that, and for peace of mind.

Thanks everyone - don't want to kill the Fam in a house fire!

I wonder if you have to slide that 'reduced' setting back When using a powerful roadside charger? Or might it auto detect?
Do you mean the DC Rapid Chargers?

If so, the slider only reduces the AC (Type 2) demand, the plug to the car that your granny charger uses.

It will have no impact if you’re using the CCS plug at a rapid charger, the big plug that uses both the Type 2 and lower pins in your car socket.

I’d always have a granny charger, useful as a backup at home and for if you’re away from home visiting or at a holiday cottage etc.

You already have a granny charger. Take that with you on the rare occasions it might be required as insurance ( with an adapter).
