BQ78Z100: SoC rapidly drops down to 0%

Part Number:BQ78Z100

Hi team,

The customer observed an abnormal behavior that the SoC suddenly dropped down to 0% from 18% when the remaining time came down to around 50mins (SoC 18%). However, in such a situation, the voltage was correctly output to CUV and the discharge current flowed without any problem, What's happening on the device inside? Could you tell us what the workaround or the correct register settings is to remove such a behavior?

Regards,

Jun
