Part Number: BQ20Z45-R1
Other Parts Discussed in Thread: EV2400, GPCRB

Hi all

My customer is getting started with the impedance track topic.

They have the BQ evaluation software and the EV2400 and can access the flash data.

In this App Note https://www.ti.com/lit/an/slua364b/slua364b.pdf

They find the following description for the Ra table:

And they have this question:

How can they read out the Rb values ? Can they access this data ?

And the same question for the table DOD(OCV,T) .

----------------------------------

They find that they can access / read the Ra table.

Hello Ueli,

The Rb table is not publicly available, it's a proprietary part of the algorithm. This is a legacy gauge, but with newer gauges we support the GPCRB tool which will calculated idealized Rb values and place them in the chem ID, when you upload the chem ID it provides you the Rb values get updated as well.

Sincerely,

Wyatt Keller
