bq40z50-R1 Impedance Track

Hello is there any detailed description about the calculation of these Parameters?

I already found some calculations in the datasheets and application notes of other devices.

RSOC = 100 x (RM / FCC)

FCC = Qstart + PassedCharge + RM,         

RM = Remaining capacity gotten with voltage simulation from current voltage state and based on the current/load setting and internal resistance and temperature

ASOC = 100 x (RM / Design Capacity),


True Remaining Q

Flt Rem Q

True Full Charge Q

Flt Full Charge Q


I would like to test if the impedance track algoriths is able to predict the right remaining capacity at different temperatures. Whats the best way to do it?

Guess the pack has to be within the same temperature for at least 5 hours right, or should it be more???
