'Anomaly in data' error in data submitted to GPC tool

Other Parts Discussed in Thread: BQ35100

I and my coworkers have been trying to submit our battery data to the GPC tool for stimulation of best ChemID. However, each time the data is submitted, the GPC tool reports and error of 'anomaly in data' due to high deviation. Could this be because I am trying to obtain the ChemID for a primary LiSOCl2 battery? I have attached two zip files containing data from two different batteries from the same model/manufacturer.

1. 7457.logfile.zip 2. logfile2.zip.

The max. capacity of the batteries is 13000 mAh. We have used BQ35100EVM module to obtain the data.

Hi Neeraj

The tool wouldn't work for LISOCL2. You match id using the name of the cell or you have to send in to us for characterization.

What mode are you trying to use the bq35100 in? accumulator mode or EOS mode?

thanks

Hi Onyx, thanks for the reply.

We would have wanted to use the IC in EOS mode but I have started to realize that it would be better to use it in accumulator mode for our application (as it is chemistry independent).

ok thanks for the info. Just make sure the consumption of the gauge in accumulator mode doesn't trump that of your circuit since the gauge will have to be on constantly to be on to constantly measure passed charge.

thanks

Thanks Onyx. I have a query: The datasheet for BQ35100 mentions that in EOS mode, SOH is determined first and then EOS condition is determined. Does this mean that we should be able to obtain battery charge status even in the EOS mode?
