BQ40Z50-R1: Reserve battery capacity checking

Part Number: BQ40Z50-R1

HI, all

In my project, i want to reserve 1.2Wh when the RSOC is report to 0%. We are checking the reserved capacity under different load(20%, 50%, 80% of max power).

What i set for reserve capacity is 120cW.  However, only 900mWh is reserved during 80% of max power(RT).

From TRM, this parameter is compensated by discharge rate.

Note, 1.2Wh is reserved during 20% of max power(RT).   

           load mode = 1 (power)

           load select = 3 (average voltage x average current)

BR.
