SOC is based on average cell voltage so it should be reading correctly. Chevy holds back 4% SOC on the top end and 5% SOC on the bottom end.
I take back the statement from my last post - before the battery replacement the PID showed Battery Capacity at 52.9 kWh. That would seem to be usable capacity not total capacity as the original battery was advertised 60 kWh and GM held back 9% of the capacity for a usable capacity of 54.6.
So 58 kWh is more than the old battery. Now is that just from the car learning through repeated charges or did the dealer reprogram the car like they said? No way to know.
One thing that did drop a lot with the new wheels is the calculated efficiency. With the old wheels I was showing about 5.0 mi/kWh. On the half charge after the wheel swap I'm down to 4.5 mi/kWh. That would make sense as with the undersize wheels the car would think it was going farther than it actually was.
I haven't plugged in my OBDII scanner and used Torque Pro to check the PIDs for almost 2 months so I'll need to do that.
