MG4 51 kWh charging speed on 3 phase system and on solar panels

[unbornidentity]

Perhaps you misunderstand ... my car takes 6.4kW charge rate (per the charging I did Friday evening and overnight); my EVSE (wall box) delivers 7.2kW for the car to take 6.4kW of it. (So approx. 89-90% efficiency, per the app numbers). 6.4kW is within the 6.6kW rating of the car's onboard charger.

I’m not misunderstanding you. Mine doesn’t. I’ve never seen my EVSE go over 6.6 with my car and the car says it’s charging at about 5.8kW

There is usually a setting inside the EVSE to limit charge current (smart ones should do that via the app).

Yours doesn’t seem to be at max, maybe intentionally if your wiring can’t safely support 32A continuously.

Get a smart, 3Phase EVSE that will reduce the charge to your car when using heavy appliances in your house

Which model exactly and where from to take this? Maybe it is available also in Romanian market.
Thanks

Nope that’s all the car is taking. I had a Cupra Born before and that would draw 7.4kW

Look for something with dynamic load balancing. If you really what to go down the road of PV charging then people usually get a Zappi EVSE, they do a 3phase version also

Ok, have you a tethered cable or do you use the one that came with the car?

Tethered. I’m not worried about it though. Even the Ohme app says max AC charging 6.7kW with my car selected and that’s basically what it draws.

Thinking about if it can go 7.4kW but the charger thinks it can only take 6.7kW that would explain it.

Assuming Ohme ‘said’ 7.4kW for the Cupra, then it seems your EVSE is limiting the current based on profile?

Yeah looks like it. They get the data for the cars from the EV-database.org and it states 6.6 on there. Will set it as a different car at some point and see what happens but I don’t mind it being a bit slower. Means I get longer cheap rate slots when it schedules outside of the normal cheap rate ?
