I’ve now had 2 failures out of 3 rapid charging attempts, both in 350 kW chargers. No connection first try, then HV battery kicked out on the 2nd attempt. Disaster! Called in the AA both times, but just as they were arriving, perhaps 30 minutes after the failure -Bingo! - the car started working again. Did not risk it again on the first occasion as we were only minutes away from our night stop where I could granny charge. This last time was at Reading West services with 20% SOC, headed for Cardiff, so had to cross fingers and re-connect. This time it worked, but my wife was so put off that we decided to do our road trip to France in her ICE car in case it happened again. I’m taking the ZS to the dealer next week to see if there’s a fault.
What were the failures? I know you mentioned no connection and hv kickout, what did the display say?
I've just driven 120 miles to north Wales last week, stopped to charge from 75 to 95% whilst we ate and it maxed out at about 20kW.
Found a 7kW charger to top up whilst at my destination, planning to charge at a 150kW instavolt charger on the way back, expecting to get at least 50kW if not the 100kW the MG website mentions.
On the way home, stopped at the instavolt, it started at 22kW then slowly dropped down to 8.. So I stopped it and reconnected, and it did the same thing.
After waiting ages and giving up, deciding to go to a tesla station, I noticed the car next to me was going at 120kW so the chargers were fine...
Got to Tesla charger, max 250kW, so figured I'd have better luck. First charger wouldn't work, so moved to a second.
Batter was at about 16% when I plugged in, started charging at about 39kW, and started to slow down to 36kW by 50%, and jumped up to 41kW just before I decided to unplug at 55% with enough miles to get home.
What I expected to be a 2.5 - 3 hour journey with a single charging stop, became a 4 hour journey and 3 charge attempts.
