“Fast Charging” - at 3.6kW or less

[dsimpkins]

FYI the charger on the SE is rated to 6.6kW

Not on all SEs are 6.6kW, my LR is 11kW

FYI the charger on the SE is rated to 6.6kW so you'll never get any more than that. I concur re. 87% efficiency for a 7kW wall box/EVSE ... (I've seen as high as 94%). For a granny I'd expect nearer 80% efficiency. (I tend to see about 1.85kW into the car per the app - back when it used to show charge to 2 decimal places).

The MG granny is plugged into a Tapo smart plug and while monitoring the charge, the Tapo sees a load of 2.2kW, but the car gets 1.9kW (might be 1.87 but I can’t see that on the new app), that’s still 85 to 87% efficient. I think the efficiency is mostly in the charger itself. The losses through the cable or granny are minimal. Hence the numbers above from my experience.

I bow to your empirical data.

Fair comment - albeit both myself and @fnegroni have SE SR so only single phase anyway. And only the MY22/Phase 1 SE LR came with 3-phase chargers - MY23 versions don't.

That is true, but very pleased to have the 11kW charger in mine.

What’s the max that you see? I would guess 9.5 kW (reported by the app with the car locked and switched off).

 

[dsimpkins]

Yes, that sounds right, I don't check it anymore, it just works.

Pleased to report that the £15 I was charged was clearly a deposit; this has been replaced by the correct sum for the kWh taken.
Also, I have checked my Type 2 - 2 cable and pins L2 and L3 are empty, so single phase - which explains why I wasn’t getting about 7kW. As another poster said, somewhat annoying my dealer didn’t refer to the fact that the cable was single phase. So, for safety, I will get a 3-phase cable.
In a sense, I needn’t have posted had I had known what I have now learned. The willingness of others to guide others is what makes this Forum so brilliant. A BIG thank you to all you knowledgeable people who are tolerant of and happy to teach we learners.

* Shouldn't apply in @dsr's case as they have a Trophy ER and I'm pretty sure they come with a 3-phase charger.

Various non MG websites list the ER as only 6.6kW and I haven't found any reference to it on the MG website at all. Unless you already know for sure I'd confirm with the dealer and/or check the pins on the car socket before buying a 3 phase cable.
