Hi TI team

We are evaluating a new cell for our project. Could you help us to confirm which chemical ID(for bq34z100-g1) is right one.

Attach the discharging curve for your reference and please let me know if you need more any other data. Thanks

Hey Luo,

Please use the GPCCHEM tool (https://www.ti.com/lit/an/slva725a/slva725a.pdf) this will give you a report and tell you what ChemID is the best match for your battery

Regards,

Nick Richards

Thanks Nick, just double confirm that to get the ChemID is just only need a log got from the process that relax --> fully charged --> relax --> discharge to empty --> relax (similar as the below picture shows). No matter the log is got by TI tools or any third part tool. Right now, our test setup is without TI tools

Hey Luo,

Yes, your understanding is correct. All your log needs is a column for voltage, temperature, current, and elapsed time
