Bq78350 Reserve capacity and EDV threshold

$

Hi,


I work on bq78350 and I have some issues with the remaining capacity estimation.

I have 4s2p Lihtium Ion battery and I need a reserve capacity of 3% (210mAh / 7000mAh).   So Battery Low = 4% and Dod at EDV2 = 15728 and Design Capacity = 6790 (7000 -210).

When I dishcarge the battery, I get a fall (7% to 4%) in the remaining capacity estimation at EDV2. Below the gauge work well.

Anybody have already got this problem? A solution?
