BQ20Z90-V150: About bq20z90-V1.50 + bq29330 - The confusion of the whole battery module

Other Parts Discussed in Thread: BQ29330

Hi TI Power management team,

Our company has used the whole scheme of BQ20Z90-V1.50 + BQ29330 module as our power supply scheme. Now we have a demand to count the number of charging and discharging cycles. We have a few questions to ask:

1. Which register should be read to get it? Initially we read the 0x17 register but it doesn't seem to change anything.

2. The specific amount of power needed to be consumed in a single charge-discharge cycle of the battery.

    Is it a charge-discharge cycle that requires the battery to run out and be fully charged again?

3. Can we set the threshold value to calculate the power consumption during the charging cycle?

Thank you.
