BQ34Z100-G1: bq34z100-g1 >>IT Cfg

Part Number: BQ34Z100-G1

For some of the parameters in Data Memory>> Gas gathering, the customer has the following questions:

--Ra Filter (is this the simple multiplication of the ra table, max 1000?)

--Min PassedChg NiMH-LA 1st Qmax (what is the meaning of this parameter and how it affects the result after modification)

--Cell Min DeltaV(what's the meaning of this parameter)

--Ra Max Delta (Manually change Ra Max Delta to 15% of the value of grid 4 Ra after the optimization loop is complete, the unit of Ra Max Delta is %. the 15% unit of the grid 4 Ra value should be mOhm)

--&Design Resistance (is this the value that limits the amount of each update of the Ra table)

--& Reference Grid (what is the relationship between these three parameters, will the other be affected when modifying one?)

--Qmax Max Delta% (what is the difference between this and the other parameter Maximum Qmax Change)

Could you help check this case? Thanks.

Best Regards,

Cherry

    Hello Cherry,

    Sorry for the delay, all posts will be behind due to Thanksgiving holiday.

    1. Ra Filter determines how much the Ra can change during updates.
    2. The default is Li-Ion, it is only used with NiMH batteries. It is the minimum passed charge for the first Qmax to occur. The default is 90% change for Li Ion.
    3. The Cell Min DeltaV is used to set the minimum voltage the gauge will add on to the terminate voltage during a load. The gauge calculates the voltage drop due to internal resistance of the battery and tracks this. So it will use: EDV = termV + minDeltaV.
    4. Ra Max Delta checks the bounds for the Ra value updates.
    5. Design resistance is the reference the gauge uses for limiting the amount the Ra values can update.
    6. Reference grid is the resistance grid value used for the Design Resistance.
    7. Qmax Max Delta caps how much Qmax can be updated (down or up) with respect to design capacity.

    Sincerely,

    Wyatt Keller
