BQ34Z100: Question about BQ34Z100

Part Number: BQ34Z100

Tool/software:

Hello:

The customer has a phenomenon that needs to be consulted. After the battery discharge stops, the total voltage of the battery collected through BQ34 does not correspond to the actual voltage of the battery

The software reads the voltage value of bq34z100 every two seconds. During the battery cycling process, most of them update the voltage value every two seconds. However, when the battery is discharged and left to stand, there may be a problem where it takes 20 seconds to refresh the voltage value.

At present, the software has disabled the sleep mode of the chip, but it still takes 20 seconds to update the voltage value obtained from the chip after the battery charging and discharging stops. Is this phenomenon related to other factors? thank you!!!
