AC charging.

[woody87]

Hi all.

Has any of you seen this before? I have a had a search on the forum and nothing has come up.

So my problem is when I’m using a AC charger I am only getting around 3.2kW - 3.5kW charging speeds even though I’m using a 7kW or a 22kW. I am always getting the same speed. I have never had it at 7kW as it has been stated.

The cable I’m using is a Mennekes 3 phase type 2 cable. (I know it doesn’t support 3 phase but I was given the cable from the dealer) .

Anyone have this happen to them ?

The cable I’m using is a Mennekes 3 phase type 2 cable.

It's probably an 11kW cable, i.e. 3 phases at 16A (3.6 kW) per phase. Your car is presumably single phase, so the car limits the charge to 3.6kW to prevent overloading the cable and causing a fire hazard.

Sell that cable to someone that has an 11kW car, "charger", and electricity supply, and get yourself a 32A cable. Either single or 3 phase, but a 32A 3 phase cable will be expensive and heavy to use.

Thanks for the reply. So I had a closer look at the cable and it says 20A 240V. There was no pins in L2 or L3.

If you're talking about the cable, then it's not even a 3-phase cable.

Yeah sorry i was talking about the cable.

The told me it was a 3 phase as well .

Anyway I’ll need to have a look for 32A cable.

Will a 32A single phase cable be enough or does it need to be 32A 3 phase ?

Single phase 32A will only ever get you 7.2-7.6kW, for a three phase charger (11kW-22kW) you'll need 32A three phase cable. However the MG4 maxes out at 11kW and you can only get that if you have a Trophy or above. One thing to bear in mind is the three phase cables are a lot bulkier so you may not want to store one in the car.

As long as your car is single phase, i.e. it has no metal in L2 or L3 in the inlet, then a single phase cable is all you need.

I think the UK ZS uplift is only single phase.

Thanks for the replies/help guys. Much appreciated.

Yeah so I have the uk 2023 ZS SELR and yes there is no pins/ connection in L2 and L3 of the connector on the car.

So my option is to get a single phase 32A but also should I get the 32A 3phase cable. Because I think I’ll be changing to the MG4 when my finance is up if they don’t supply a cable with the car.
