BQ25790: Faulty current reading in BQ25798 BMS IC during discharging

Part Number: BQ25790
Other Parts Discussed in Thread: BQ25798

Tool/software:

We are using the BQ25798 BMS IC with the BQ25790 driver code, and we are attempting to read the voltage and current from the BMS. Below is the data we collected:

During charging:

  • VBAT: 8V
  • IBAT: 960mA
  • VBUS: 4.7V
  • IBUS: 2.6A

During discharging:

  • VBAT: 7.6V
  • IBAT: 0mA
  • VBUS: 34mV
  • IBUS: 0mA

Why are we getting IBAT = 0mA during discharging?
