BQ34Z100-G1: Can not calibrate voltage - Calibration Cell voltage entered is out of range

Jason Gurley61

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

I have a 12.8V LIFEPO4 pack in a 4S2P configuration.

I have successfully calibrated the current, but I cannot seem to get the voltage to calibrate. I have 13.08volts across the pack and I have enabled VOLSEL in the PACK CONFIGURATION A register. I have CAL_ENABLE selected. When I type in 13080 in the calibration box and hit the Calibrate Gas Gauge button, the software comes back with "Calibration - Calibration Cell voltage entered is out of range..."

Any thoughts on how to get around this?

Hello,
I have exactly the same problem... And no answer from Texas... If I find something I keep you informed.
With this new Gauge, we don't know if the srec is up to date (and where it can be found), difference between revA and revB EVM hardware...
I hope not to spend weeks yet.
Regards

Hello,

The same problem here.
Even if try to calibrate with a lower voltage (like 400mV), I get this error.

Hello, guys.

I've solved the problem by replacing the .bqz file in (C:\ti\BatteryManagementStudio\config) with a new one that I found in a thread.

0602.0100_0_16-bq34z100G1.rar

I hope it helps.

Mauro.

Hi Mauro,

This worked! Thank you.

BTW...so someone else doesn't make the same mistake I did...

Be sure to move the old file or delete the old file from the directory and copy in this new one shown by Mauro above. Otherwise BQStudio will pick up the old file instead of the new one. I tried, mistakenly, to renamed the old file from (0100_0_16-bq34z100G1.bqz) to (0100_0_16-bq34z100G1_old.bqz). BQStudio found and used the _old file instead of the new file.
