There are some posts elsewhere about faults after charging. One of the answers was turn it off fully for 10 minutes and try again.

Hi, was that on a rapid charger and what % did you charge to?

 

[Harves]

Yes it was and I put about 25% in

 

[Harves]

According to GeniePoint I put 17 kWh in

I don't actually own the MG5 yet but I did see that posted about before so glad it worked for you.

Anyone who has one, can you explain what happened to Harves here?

Is it to do with the 12v Battery getting drained?

@Harves You said you put 25% / 17kWh in to the car - what was the starting percentage? Most reports of issues are when charging to high 80% and above on a rapid

I think there are 2 different issues.

1) sitting in the car using infotainment and aircon/heating while charging causing the 12 volt battery to drain.
2) charging to 90% or over on a rapid charger causing overheating.

Does the 12 Volt get recharged by the main battery just during general use?

 

[Prof1967]

I believe it is when you have pressed the start button twice with your foot off the brake and when actually being in drive mode (pressing brake pedal when pressing start button).

If you have pressed the start button once without pressing the brake (amber light on start button) you will drain the 12v battery.

 

[Prof1967]

Recharges when in drive mode. Takes electric from the battery pack and puts it into the 12 volt battery.

The 12 volt battery powers everything in the car apart from the electric motor. If the voltage drops too low none of these systems will come on so you won't be able to start the car.

The 12v is charged by the main battery when the car is fully on but not when it's half on (whatever that mode is called).
