MG4 Rapid Charging

[munkiev]

Well we have just returned from another long round trip from Cornwall to London and back. Fast charging is really impressive on the new Gridserve chargers what speeds are people seeing ? We have been getting over 130kwph on the app ? barely giving us enough time to get a loo stop and a quick snack in. Super impressed tbh

Looks like the MG4 loves Rapid chargers.
What percentage does the charge rate start to drop off at!

Was that on the new Solstice Park Gridserve changer bank on the A303 by any chance? We're planning a stop there in the near future.

Why's it in KM? Is your car not setup for UK?

It is an in-app setting independent of the car, I have needed to reset mine before now.

Both there and at Exeter on the return leg

Didn’t really have time to check I’m afraid just kept it in the sweet spot and got on with journey after 80%

I've modified the title of your thread

I must admit- i ve never seen anything above 75KW (for charging power) on our MG4 (and we have done every charger, Fastned, MFG, Ionity, Porsche/Shell, Insavolt, ospray ) - well done on this! (munkiev - is this for an MG4? -not as your profile?)

My Trophy is still charging over 50kW at 80% and will carry on up to low 90s reasonably quickly. I've also been really impressed with it.

Do you have the 51kWh SR? I think it's only the 64kWh cars that will do 140kW

 

[siteguru]

The SR (51kWh) should still do "up to" 117kW charge rate though ... but I don't think anyone has achieved anywhere near that yet.

Yes, there was a previous thread on how this seemed to be limited to 87kW or so max:

MG4 LFP/NMC batteries

So, I did a video on getting a pre-order of an MG4 in Australia: One of the commenters said the MG4 base has an LFP battery, and the others have NMC. I didn't believe it at first (none of the YouTube reviews said this iirc), but checked on it and it's true apparently...

Dont forget that the DC charger may not provide full power if those around it are also in use. They “talk to each other” and load limit so the feed supply rating isnt exceeded

Yes, that's true but there were a lot of people complaining a while back, I don't know if MG have a software limit on the SR or if they have raised it since.

I wondered if this was part of the CCU update - or whether that's more related to charging the 12V battery. ?‍

Well, we tried Gridserve Solstice Park this weekend and it was a crapshoot.

6 out of 8 chargers were not working (but didn't say out of order), so we tried a couple and then a guy who was charging said he'd phoned Gridserve as he was only getting 30kW and they said the chargers were showing as not working properly, so he'd reboot in next 30 minutes and/or send an engineer out in next 2 hours.

The Gridserve software seems flaky, really annoying to have chargers showing as working online and on their screens but actually not.

We faffed around trying a few of them then headed to Tesla Wokingham instead (50 miles away) as we knew that would "just work". Not impressed if this is the state of the art from Gridserve.
