Part Number: BQ34Z100-G1
Other Parts Discussed in Thread: BQSTUDIO

Hello,

I am not getting an ocvtaken indication at the end of a discharge cycle.

I have the data capture from BQstudio logging as well as the data flash setup file.

Can you take a look at my data and setup and please help me?

I thought I had it set up properly.

I'm not sure how to attach the files here.. please advise.

one more thing.. I arbitrarily changed Configuration>>Data>>"Device Chemistry" from PbA to AGM.. could this cause an issue? Does the firmware use this string for anything?

Hi Bryan,

I found an issue with my setup.

The load Mode register and Load select register values were swapped.

These registers are located sequentially in memory as Load Select then Load Mode but are discussed in the specification in the opposite order so when I loaded the values I arbitrarily set the load mode to power mode instead of current mode.

I am re-running a new battery cycle now and will re-submit that for evaluation by Monday if needed.

In the meantime, will leave this post open until I have valid results.

Thank you for your patience.

-Tim
