The 2nd Ah value seems to be current pack capacity, as it varies with SOC. So I was surprised to see the 2nd Ah higher than the first value after charging to full, until it auto stopped. My numbers are 37.3Ah and 39.0 Ah; any idea how to interpret the 39.0 Ah ?

Thanks

2014 iMiEV, haven't figured out how to upload a photo; but the below links to one of your screen shot which shows 39.5Ah and 35.3Ah values at 91.5% SOC. In my case, it was 37.3Ah, 39.0Ah at 100% SOC. Is the 2nd value to the right how much Ah was putting into the pack ? my guess is that the first value is the BMS capacity model, which would get updated with the 2nd value had I performed a recal charge (from 2 bar to full on level 2).

On the screen, a value of 39.5Ah means that this option is available taking into account WWB degradation.
What the dashboard shows (89.5% and 91.5%) corresponds to a capacity of 35.3 Ah.
35.3Ah = 89.5% - the remainder of the charge.
89.5% corresponds to the dashboard.
91.5% corresponds to BMU calculations.

your electric car 2014 iMiEV,
you are using hobdrive which version?
you need to use hobd_1.5.47
or the latest version that is available now

am using version 1.5.48
So how can the 2nd Ah value (35.3Ah entry) be higher than 1st Ah value (39.5Ah entry)

Tried the cell smoothing feature yesterday as I actually need to use it and I couldn't get it to work.

It's not clear what mode the car should be in while running it ? Plugged in charging, or just turned on in READY mode ?

I was able to get it working once but when I quit the app and went back into it it was off again, so it doesn't seem to continue when the app is quit ?

Most times when I have tried it (car in READY, near full charge) I just get an error that says cell smoothing cannot be activated.

Running version 1.5.50 Beta from the Google Play store.

car mode is connected to charging, the cell is at least 3,800 volts

Ok. Does it stop the charging when cell smoothing mode is activated ?

If not, I don't see how it differs from just letting the car balance the cells during charge >80% SoC anyway.

you need to catch the moment on a fully discharged battery

If it is turned on correctly, then it will charge with a small current with simultaneous balancing, the process is different from ordinary charging, it takes a very long time.

You can also turn it on again after standard charging, because it does not balance them constantly, but only minimally tightens the weakest
