Dear All,

I get an issu with SOC jump at low temperature. I did a resistance temperature compensation optimization following the sluubd0.

I get with the GPC repport the following message : Due to GG file format issues, GG values have not been updated

Also I didn't received teh chemdat file

Attached send data and the report.

Can someone help to understand what I did wrong ?

Thanks

Hello Mahfoud,

It seems like your first step you would need to do before you do your resistance temp compensation optimization, is to go in bqstuido and perform a calibration within the calibration tab, once you complete that reference the GPCCHEM tool to find your ChemID for your system and you should look for the lowest DOD percent error %. Once you get your ChemID update your data memory tab and focus on the critical features below and once this is complete you'll need to perform a learning cycle.

Critical features:
Design Capacity, Design Voltage, Charge Term Taper Current, Dsg Current Threshold, Chg Current Threshold, Quit Current and Term Voltage
