Incorrect. We did had the message when we got the ZS (mk 1, second hand) delivered.
It took us about 7 months with a weekly charge to 100% to get the battery pack completely equalised.
So if you get the message, you are way too late with balancing.
Yes we did start balancing immediately after the first warning.. Every day we charge it to 100% and leave it plugged in till the next morning. The min. cell Voltage only raised from 3.72V to 3.74V after 10 balancing cycles (which take approx. 4 hours each time).
Why doesn’t it balance for 10...
Just purchased a second hand MG ZS ev from 4-2020 with 28400km.
We got a lot of “please slow charge warnings” right after purchase so bought a OBD2 dongle.
This is what it says, SOH 97.75% but delta V is 400mV. Could this be a damaged cell? Or could it be resolved by balancing?
