Fast charging problems

[Catoma]

I'm crossing France on Ionity chargers. In all of them I have the same load, no more than 40kW and dropping to 32kW in a short time. I have gone to a Tesla super charger and same problem, 32kW maximum. MG ZS EV LR Luxury.

What temperature and state of charge?

 

[Catoma]

24° 40%, 50%

Now 28 degrees, 31kW... So slow...

 

[pollenface]

when you say degrees, is that F or C?

Celsius

I'm also experiencing slow charging on MG ZS EV 2021, even at rapid 150kw chargers it won't go above about 38kw. I've tried at low (20%) soc and high, it's been cold (2-8deg c) and warmer (14deg c), but since it's winter I haven't had any hot days to try it on.

MG seems to have a big problem with first gen ZS EV HV batteries down throttling DC charging because of cell voltage mismatches. These issues indicate a warranty claim on the HV battery. Collect evidence by reading the OBD error codes, saving data on the battery cell mismatch with Android apps like "Car Scanner" and "eZS" and fast charging curves on DC fast chargers (Alpitronic).

Assert your rights and demand a proper diagnosis or HV battery replacement under warranty. Contact your national motorist society or a lawyer directly.
