Cell balance?

[dragon2611]

Assuming the data is accurate should I be worrying about those cells, the conspiracy theorist in me wonders if mgs fix for the check hv battery issues was to loosen up the tolerances

Soc is about 72% was charged about a week or so ago and allowed to do a balance

Seems a bit better after a drive

How long did it take to complete the battery balance?

How long did it take to complete the battery balance?

Seemingly not long which makes me wonder if it actually did it.

 

[Jomarkh]

Did it get to 100% ok and what EVSE were you using?

 

[dragon2611]

Yes and it’s an EO mini pro 2.

It stopped drawing current long before the end of the octopus cheap period so I didn’t bother overriding the charger schedule.

 

[Jomarkh]

Had it dropped to about 300w?

 

[dragon2611]

Had it dropped to about 300w?

Charger was saying 0w and ihd load seemed to corroborate that as it was about what I’d expect for the devices that were on in the house at the time.

The build you have has not been set up correctly for your battery yet. I think the MG5 has a lot more cells than the MG ZS EV.

Hi Dragon 2611, where did you get a BMS cell monitor and how did you produce the graphs?

It’s ovms but given what @GreyPeter said it probably wasn’t getting all of the data.

Since he was the one working on the mg5 code he’ll know what it was polling

I've got a 2021 zs exclusive and normally charge mine to full and balance it once a month on a granny charger at home. Admittedly the balancing time is a bit flaky but it's always around 450 soc when it's done. I'm happy.

Just for clarity I don't use any gizmos or apps. Just look at the light sequence on the MG grill badge ....
