BQ78350-DEVICE-FW: Battery Self-Discharge Anomaly

Part Number: BQ78350-DEVICE-FW

Tool/software:

Dear TI,

Although we set the self-discharge value of our 10S2P battery to 0.88%, during our 60-hour sleep mode test the battery SOC level

Test Start point,

DUT screen capture after 60 hours,

While we expected the SOC to drop by 2.2% over 60 hours, the SOC remained at 22%. How can you explain this situation?

    I can't tell from the pictures as the resolution is so low. It looks like Remaining Capacity did drop while SOC stayed constant. The gauge keeps SOC constant when there's no current, regardless of self-discharge settings. Please apply a discharge current during your test and you'll see SOC dropping with this current and the self-discharge settings.
