BQ34Z100-G1: BQ34Z100-G1 calibration for Panasonic NP-2 battery cell

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

Hello,

Is there any configuration file for BQ34Z100-G1 for Panasonic NP-2 battery cell (6 cells in series, nominal voltage of series is 7.2V a nominal voltage of 1 cell is1.2V) ?

I cannot find it in chemistry configuration files (even the newest one). BQ studio 1.3.86 does not show correct values. It shows 722mV instead of showing 7222mV. Also does not show corret parameter like cycle count, current, state of charege etc.

Thanks for any help

Hello Martin,

You will need to upload the ChemID for the batteries and program in the parameters you want for the battery according to the specifications from the battery manufacturer.

You can try to find the exact chemistry match, or you will need to use the GPCCHEM tool to find the best fit ChemID if your battery doesn't have an ID. I would recommend following the user guide for the setup and in the TRM section 3.4 on voltage calibration might be the cause of your incorrect voltage reading, the voltage divider parameter needs to be set for the application.
