Dear TI Support Team,
I'm using BQ76907 5cell configuration trying to compute Cell gain.
Vcell mode = 0x05
Cell 1 Gain = 65535
Cell # Gain Delta = 0
Cell # Gain was calculated using following formula with 2 precise DC voltages(2.5V and 4.5V) to cell input and averaging multiple raw measurements in 16-bit counts obtained from the cell # voltage() command for each voltage
2.5V raw | 4.5 raw | Gain | Gain Delta | |
vcell1 | 13777 | 24649 | 12055.92 | |
vcell2 | 13761 | 24620 | 12070.36 | 14.432913 |
vcell3 | 13774 | 24640 | 12062.58 | 6.6570533 |
vcell4 | 13778 | 24660 | 12044.84 | -11.078775 |
vcell5 | 13760 | 24613 | 12077.03 | 21.10592 |
1. Cell 4 and 5 Gain Delta = (Cell 4 Gain - Cell 1 Gain) OR (Cell 5 Gain - Cell 1 Gain)?
2. Cell 6 and 7 Gain Delta = (Cell 6 Gain - Cell 1 Gain) OR (Cell 7 Gain - Cell 1 Gain)?
3. In my application, Cell 4 and cell5 gain to be stored in which data memory address? Cell 5 and 7 or cell 4 and 5?
