Hello,
I try to use the BQ34Z100 with battery 3S6P (Sanyo Lithium ion battery UF553450Z). With the bq Evaluation software, i set parameters "flash data" following application notes.
Sometimes parameters are about the battery and sometimes about cell inside the battery. So, I'm not sure to set correctly. i dont find AN very explicit.
I get good values of current, voltage and temperature but SOC, Remaining Capacity and Full charge Capacity are always at 0.
I sure, I completed a parameter with bad value
I haven't done charge/discharge cycle yet . I don't understand how is C/5 or C/20 level.
I join the .gg file . If you see something wrong, thanks for your feedback.

In the .gg files, i thing the "Cell V at Chg Term " shall be 4200
