MGS5 Trophy Long Range - 3 phase charging ?

[OriginalBigAl]

You will love me then....

Cars with 3-phase 11kW chargers (like my VW and also MG4ER) internaly have 3 x 1-Phase 16A chargers. On a 3-Phase supply they run one per phase for 11kW total. On a 1-Phase supply they run 2 chargers in parallel for 1-Phase 32A = 7.4kW.

You will, of course, need a 7.4kW 1-Phase or 22kW 3-Phase cable to supply 32A down one phase connection

I do, lets get married , but only if you have a 22kw cable suitable cable , I knew about the first bit , but not the second. I'm only a pauper with a 11kw cable.
I do have a hectare plus of land , do you have tractor and a key? Cue the Wurzels.

Actually , that's doubly interesting because we have a couple of gites for which we want to offer EV charging. We have the 3 phase but adding a 7.4 kw single phase EVSE to the garage could cover all eventualities , as well as back up in case the 3 phase EVSE went down . We originally chose 3 phase to help balance the system as well as not dragging 6.6kwh out of one phase over a longer period.
We use the cheap night time leccy , not only for the car but the white goods as well and water heating so a bit of juggling with the timings would be needed as so not to overload the phase on which we want to put the new EVSE .

What a multi faceted world, wouldn’t it be boring if we talked ev’s and maligned ice’s all the time

2nd reply, if this is the case , then why do manufacturers bother putting in 7.4 single phase equipment? There was no price premium applied to mine when ordered so cost should not be a factor. Indeed having two systems is more expensive as opposed to the same generic charger being installed across the range(s) , less complication , spare stock range, skill sets in installation and repair and same software updates.
Going back to the OPs question , the owner should then be able to plug into either of the two options and expect it to work as planned. ( with a suitable cable ).

Hmm... I think I have a 22kW capable cable that came with my VW - never used it though.

Nice of you to offer and I really do have a tractor but... I already have two hectares... oh, and a Mr Everest SW France does sound tempting though

Two random thoughts...
1) assuming your water heater is 3 phase, could you add a switch so that just uses 2 phases when you want to run a single phase EV charger?
2) could using a plug-in single phase EVSE help? Assume you can draw up to 16A via a schuko socket or more via Commando socket - that could be a cheaper alternative than having a wired EVSE installed?

We have a 30 kw supply at 10kw per phase, with the house and two gites each receiving a phase each from a central utility room . The utility and garage still run the full 3 phase. I already fitted a 16A commando socket on a dedicated line from one phase to run a granny ( back up ) charger , so we offer that as a service as well as the 11kw should anyone have a suitable car. To give any future clients a better holiday I was wanting to include a 7.4kw single phase charger but trying to decide which phase to connect it to is the predicament I am mulling over.
We are trying to make each property independent , so if in the future we need to sell one or two of them , both the water and electricity can be switched to new meters and supplies for each property at the central utility (communal ) room. One could stay 3 phase with the other two single phase and up the power supply from EDF for each to cover the new owners needs.

How about wiring a 32A commando on each of the other two phases (one for each Gite)? Then a "granny-on-steroids" 7kW plug-in charger which you can plug into either socket as needed? We use one of these - works well, especially with the adjustable current settings....

That could work , I'll have to make its portability less portable , but , yeah the ideas growing . Thanks , good spot.
