I've just visited a friend who also bought a 2015 Soul EV, just a month after me. He is now over 60000 km too, and I thought I should go there and check the BMS values in his car to get more statistics.
But he had the 60000 km service done only a couple of days earlier, and I found that the same software upgrades as I got had been done to his. So no deterioration, energy counters or active seconds counter (well, 13 hours...). Also the blue indications were now active during Quickcharge as in my car.
He's service wasn't done by the same garage as mine, so now it really looks like it wasn't a mistake and this upgrade might come to everyone (maybe at 60000 km / 40000 miles..). In that case, Kia must have a database where they save the old statistics from the BMS, before they do the upgrade.
I have noted a different behaviour on the cell balancing when Quickharging: It seems they have moved the balancing process from 82% SOC to 92%. My friend was actually surprised the first time he used QC after service, because it was finished quicker than it used to. For me, the 84% QC:s I've done since the upgrade have all passed without any signs of cell balancing, but the only time I've restarted to 94% I could see the signs in the log afterwards, even if it was pretty short.
My det.numbers since last report (11 changes after BMS upgrade):
Det Max: 8.5-8.1-8.1-8.6
Det Min: 6.6-4.9-5.7-6.3
