Did you like the click bait in the title 
- I confirmed a pleasing fact this morning. Since owning the MG and reading about peoples' experiences with EVs and 12v battery issues, I wanted to see whether the MG charged the 12v battery while it was fast charging. I tested it today, using a multimeter to check the 12v battery voltage before and after starting a (fast) charge. Sure enough, before charging (with cable plugged in and car locked, but charger delivering 0 amps) the battery read 12.00v (a bit low - I would have expected 12.4v for a car that was used only yesterday). I then started the charge using the Ohme app, waited for the charge current to rise to 32A, then measured the battery voltage again - 13.25v - Yaaaayyyy - 12v battery is indeed charging along with the HV battery .
I'm happy now, so have come in for a cup of tea.
