BQ34Z100-G1: During the golden learning process of NiMH battery, the RA table cannot be updated during discharge, and the Update Status remains at 0x05

Hello,

This question has been assigned and will be reviewed within the team when possible. In the meantime please attached associated .gg/.log/data files associated with the project.

Thank you,

This is a relatively complete log of Golden Learning from step 1 to step 5,
Charge.rar is the gg file during charging, while charge.log is the log during charging
Discharging. log is the log during discharge, while discharge.rar is the gg file during discharge

Hi,

How was this chemid selected? did you use the gpc chem tool?

We have sent the battery to your laboratory in the United States, and your laboratory has provided us with the chemical ID, which is 6131. The correct chemical ID has been configured for bq34z100g through bqstudio

May I ask if you have found the cause of the problem

Hi,

The current reading is flipped, chg current should be positive and discharge current should be negative.

You should be able to correct this in calibration.

No register configuration was found in bq34z100-g1 to modify the current direction，Is this a hardware issue?? Our hardware schematic is as follows. Could you please help us check if there is anything wrong?

FUEL_SRP connected to the negative pole of the battery

We have modified the circuit as shown in the figure below.

During charging, bqstudio displayed a positive current, but during golden learning, step 3 failed. Qmax did not update and the update status was 0x04, not 0x05. Attached are bqstudio's register log and data memory log. 

The final register and memory data are shown below
