BQ40Z50-R1: RSOC change from waking up after seal and shutdown

Hi,

We are using a BQ40Z50-R1 with a 1S3P li-ion battery pack (Molicel ICP103450DA, 3.7V 6600mAh).  The ChemID, voltage and capacity are set.  The issue is the Relative State of Charge (RSOC) reading is different after waking up from a Seal and Shutdown.

1.First, the battery is discharged to RSOC=30% to prepare for shipping.
2. Then do a Seal and Shutdown of the battery pack.
3.Once the battery pack is waken up, the RSOC is around 43% (+/- 2%).

This happened to all of our battery packs (20 pilot build sample).  The RSOC stays around 30% if we do not seal and shutdown, but once the unit is sealed & shutdown and waken up, the RSOC jumps to around 40%.  

Is that something with the golden image setup or the waking from a seal and shutdown does a recalculation of the RSOC so we get a different number?

Please provide some assistance as we need to get this solved before sending our customer more battery packs.


Thanks,

Dick
