I haven't found a similar topic on this forum, apologies if it's there and I have missed it...
I have a MY13 with 223 000 km on clock, SoH 25.4 Ah. According to PhevWatchdog statistics, this significantly below the expected SoH at this milage. So I am wondering if there is a reasonable way to improve capacity with replacing the weakest cells in the package. The BMU was reset 400 days ago by the previous owner.
According to PhevWatchdog the maximum cell voltage difference ever measured is 88mV, but from these overall statistics it is still not clear to me which cells might worth to be replaced, if any.
I have already ordered a miniVCI, and plan to use it with MUT 3, so I was wondering if I should perform a DBCAM, and check the cell voltage at the low end of the DBCAM process, and also check which cells stop charging first during the charging phase. But how could I log the cell voltages during the DBCAM? As far as I know PhevWatchdog only logs the min and max voltages, but not all the cell voltages separately.
-what might be the best way to identify cells to be replaced?
-does this plan make sense at all? (replace the weakest cells -> BMU reset -> smoothing -> DBCAM)
