BQ40Z50-R1: Impedance track on BQ40z50-r1

Part Number: BQ40Z50-R1

Hi all,

I have 2 questions to ask regarding the impedance track for this particular device :

1) Suppose the use of the battery pack has constant 1A load.  But during the 1A load, there are times that the discharge current will increase to 10A.

Will the Ra table still update during these high pulse loads?

2) Can the ra table update be disabled?

Thank you in advance

Best Regards,

Ernest Yong

    Hello Ernest,

    1. The Ra table will update on discharge. The load current variation is ok.

    2. Disabling Ra table updates will result in poor performance of the gauge. I don't think there is a command to disable it.
