BQ40Z50-R1: BQ40Z50R1-Error

Max

Part Number: BQ40Z50-R1

Hi

We have developed a 4S1P battery pack using BQ40Z50-r1 IC

We have put the battery under long run(Charging and Discharging) and we are Logging the Parameters such as Battery Voltage, Battery Current,Temperature,Cell1,Cell2,Cell3,Cell4,Battery status and some more parameters.

During charging the Battery logging  Parameter is normal and data is found to be normal.

But During Discharging while logging the data we got an unknown value (5911) on the logging parameters randomly. But it wont affect the Battery discharge cycle behaviour.

Kindly suggest a way to sort it out.

Attached a log file which has unknown value on logging parameters.

While Charging using the EVM-BQ2470S we are not facing any issues and Battery behaviour is normal during the charge and Discharge.

    Anandan,

    What is this information being logged with. I would assume you are running into the gauge being busy so you are getting a Nack, which your logging tool doesn't know how to understand. 

    You should change your code to "if Nack: retry or dont log"

    Thanks,
