11kW Charge Hub only 3kW output

[brilig]

I have a 64kWh MG4 which has a NMC battery.(I have read that the the 51kWh model has an LFP).
Installed in my garage is a wallbox from Heidelberg. I believe it is rated at maximum 11kW. When i charge I get 9.5 kW everytime.
When he first installed it I was only getting 3.5 but he came back and made an adjustment.
In now reading the installment instuctions I see that there is a small adjustment "dial" in the box which can be adjusted. Possibly yours is similar. I would ask an experienced electrician.

I have a standard excite and an EVcharger portable 11kW through a 3ph 32A house socket and it achieves 9.9kW.

Some earlier models had the additional pins, current models apparently do not except the 77kWh equipped vehicles.

Yours is not an MG4 though. The ZS EV models in Australia all come with an on board 3-phase charger.

It requires a model with an on-board 3-phase charger.

European markets did get MG4s with 3-phase on-board chargers as did very early models of MG4s in the UK but many of the current model MG4s (e.g. in UK, Australia) do not. These have a single-phase on-board charger, max 6.6 kW, except for the 77 kWh NMC battery model which retained the 3-phase charger.

Yeah i realise that. i saw the post on the 3ph charge rate and was surprised. Clearly the on board systems are different.

Hi all.
We've had a Charge Hub 11kW installed and oddly only getting 3kW when charging regardless of the battery % at the time and the temperature.
The car is set to AC Current on the charge options, I'm assuming this means allow the max current available as the other options are 8A and 16A.
The Charge Hub has been installed on 32A 400V 3 phase circuit so there should be a bit to work with.
If I hook up to the local free public charger I'm getting around 5kW so it doesn't seem like the car is limiting the charge rate.
It's hard to find any details on what type of output anyone is getting with this charger, I'd be interested to know what others are getting from their Charge Hubs. MG Australia haven't been able to help much, just told me to take the car in to check and they've told me they couldn't spot anything. The guy at the repair desk did say that 11kW was the maximum it could put out, I pointed out that 3kW was a long way off this though.

Regardless of the charging speed, how much fun are these cars to drive? The MG4 handles really well and the linear power delivery translates to the biggest sweet spot I've ever encountered.

My granny charger from a 10A socket pulls only 7A (1600 watts) maximum. I don't mind that because I get a full 63km charge overnight, at a low charge rate, which lowers the chance of a battery meltdown.

It's a HS PHEV by the way.

it is probably your cable. I have an MG5 and charge at my office which have 11kW chargers. The standard MG cable that came with the car was only giving me a 3.6kW charge as it was a single phase cable so it could only pull a third of the 3 phase 11kW charge. I bought a 3 phase cable from Amazon and bingo! I now get between 10-11kW charge.

 

[siteguru]

It's not the cable ... the OP's car only has a single phase 6.6kW onboard charger. An 11kW 3-phase charge point will only deliver maximum 3.6kW per phase ... even with a 3-phase cable the OP's car will still only see a maximum of 3.6kW.

Ours is an MG4 Essence 64, is definitely only a single phase socket, pins L2 and L3 are blanked out.

I got a Cyberster GT dual motor,
in the sales brochures it said 11 kW on board AC charging.
I can not find any information in the given manuals.
I have a 3 Phase house and bought the MG 11 kW charger to get 3x16 amp.
However, I am not sure anymore if the car has 3phase 11 kW onboard. It would be meaningless to install the 11 kw charger as I would get 3.6 kW only anyway.
Attached a picture of my charging port, can anyone identify if this is 11 kW pins or 7 kW pins?

If L1, L2 and L3 pins are all metal, then it's 3-phase 11 kW.

It has the L2 and L3 pins in the picture so should be the 11kW onboard charger

Look at post 4 on this thread which shows them absent on a 7kW version

Only getting 3kW from an 11-22kW charger when the specs for your car say it can accept 11-22kW is because you're using a 7kW 1-phase cable instead of a 22kW 3-phase cable.

 

[cyberthai]

Thank you guys, all clear now, than I have the 11 kW on board and will install my wallbox soon.

Another thing to check if your home charger is not charging as fast as it can, does the system have a CT clamp installed to balance the EV charger with all the other loads on the system. If you are running a 7kW electric shower in the house and want to charge your car at 11kW off of the same supply that is a lot of load on the system

L1 is for single phase.
L2 and L3 are the extra three phase pins

It may also be because the EVSE has a current limit set (many have a programmable setting).

can a 7kW charging car be upgraded to support a higher rate of charging?

Not sure but you would need to swap out the 7kW onboard charger with three 3.5kW units.

No.
