47925 km
Battery Capacity 34.6Ah
battery condition 72.08 PMC
cell volt difference 0.005 to 0.01 V



Sad update on my car's battery:

Checked with CaniOn:
the last full charge was only 99 RR and 95% SoC (at about 4 hours after full charge ,see note below).I left the car parked for another 24 hours without having driven it. RR dropped to 87 and SoC 84.5%
That is a huge drop !

Data from EVpos app:

47925 km
Battery Capacity 34.6Ah
battery condition 72.08 PMC
SOC real 97% about 4 hours after stopped charging ,charger was on for more than 2 hours after charger stopped being full.
cell volt difference 0.00? ( I have a PLC monitoring charge current and times as well as KWh drawn from power point.)
Cell V max 4.08
Cell V min 4.08
Pack V 359


Battery Capacity 34.6Ah unchanged
battery condition 72.08 PMC unchanged
SOC real 82%
cell volt difference 0.02
Cell V max 4.06
Cell V min 4.04
Pack V 357 2 V drop in pack V in 24 hours lost 15% SOC . What is wrong with my battery?

Maybe this should be in the other thread?

Could it be that your 12v battery is faulty so it is constantly being charged by the traction battery?

The 12v doesn't get charged by the traction battery when the imiev is turned off, it just goes flat and won't start it.

One factor I have not included is the drop in ambient temperature.
It was stinking hot prior to the last charge (high 30s,40 one day) .Last night min was 8 or below.Battery this morning (EV+app) 17 max 14 min.
