BQ34210-Q1: RemCap value jumps on bq34210

Part Number: BQ34210-Q1

Tool/software:

Hello Team,

I am currently investigating a battery management system using the bq34210.

We want the RemCap value to become 0 when the final voltage reaches 3000mV, but as shown in the graph below, when the discharge time reaches 22,000 seconds, the RemCap value decreases, and the RemCap value becomes 0 earlier than expected.

Which parameter should I change to resolve this issue?

We perform calibration and parameter setting using the Gauge Parameter Calculator.

Thank you
