Hi,
On a device, we use a BQ27510 fuel gauge which measure a LiPo battery. We create the golden pack file for the battery and the electronics board. This device is in mass production and works pretty well but since few weeks some devices have problem.
Sometime the fuel gauge gives the bad capacity for the battery. The good capacity is 2200mAh and sometime the fuel gauge estimates it at 550mAh or 1400mAh. The configuration of the component is correct. I tested with different battery and the same board gives the same capacity.
Is there someone who have an explanation to this issue ?
Thanks
