Equalisation success.
My MGS5 is now 8 weeks old, Time for battery maintenance.
A previous attempt to Equalise the traction HV battery failed, with no apparent reason I could find.
2 weeks ago I attempted the equalisation with the battery at 15% on home "OHME" charger, probably didn't let the battery charge % go low enough, also possibly didn't set-up the scheduled charge correctly as it strangely stopped at 71%, no explanation I could see.
However on the second attempt last night, all worked fine.
I drained the HV battery to 8%, by driving home from shopping last night in the dark, heated seats and steering wheel heater (it was parky) Climate control, lights and everything electric turned on, but didn't quite get below the 10% mark, so needed to drive around without wifey after reaching home, to get the battery to 8%
We are remote and need to plan the equalisation charge when we don't have to go out early next day.
Plugged in and set the Ohme wall charger to 100% just in case of a conflict, then the MG iSmart app to "Scheduled Charging" for 12 hours from 23.30 (Octopus cheap night rate)
Kept checking near to the end of charge at around 09.00, the equalisation carried on charging for around 20 minutes after reaching 100%.
Job done, but as I'd read and self confirmed, the remaining charge appeared to need to be below 10% and MUST be carried out on an AC charger i.e. 7Kw home charger or a normal granny charger from a wall socket. Equalising will not work at on a DC charger, the ones you find in service stations etc.
