Hi ,

After Discharging the battery to the empty. The DSG bit keeps on toggling to 1 and 0.What could be the issue?

I left it more than the 5hr still the same issue.

Pls give me the solution

Thanks.

Hello Ankit,

That would make sense since once the battery reaches it "empty state" or what you set your termination voltage too than the discharge FET would open to prevent from going below its empty/termination state. If order to prevent this you would need to review your BQStudio >> Data memory, parameters and specially DSG current Threshold, OT Dsg, Cell Terminate Voltage and etc.

Thank you,
Alan

Hi Alan,

I will review the data memory and update if there is any discrepancy.

Thank you.
