BQ78350: The remaining capacity becomes zero after charging or discharging stops

Jason Zhao39

Part Number: BQ78350
Other Parts Discussed in Thread: BQSTUDIO

Hi,

We now have a product in use, a small number of encountered problems.

The remaining capacity becomes zero after charging or discharging stops.This then causes the RSOC to go straight to zero.

Other products can be used normally, and the probability of the above problems is about 1%

Hi Jason,

Can you tell me more about your application and battery pack (chemistry, number of cells, voltage divider settings)? Also, can you please send your settings (you can export the Data Memory from bqStudio to a .gg file)?

For the gauge settings, did you go through all of the required learning cycles to determine the CEDV settings (www.ti.com/.../sluub45)

Thanks,
Matt
