BQ40Z50: BQ40Z557 Qmax cell2 is negative value

Part Number: BQ40Z50

Hi

The End user feedback from the Japanese market found the 1pcs battery was not charging and had no output in the system.

After checking the parameters, the battery has been used for 8 cycles, and the capacity data of the Qmax Cell2 became more than negative 2W, causing the battery power display to be 100 %, the battery cannot be charged or discharged.

Please help analyze what is causing the abnormal change the capacity of the battery Qmax Cell2?

Attached the gg file and the figure.

Thanks

Star

  • Hi Star, 

    I have never seen  a negative Qmax value. Per TRM, the minimum value Qmax can be is 0mAh


    DA config is set to 0x16. Meaning this is a 3S application. Why is Qmax Cell 4 updated? What does the cell connection look like? 

    Please share the log file that describes this behavior. 

    Regards,
    Jose Couso
