BQ28Z610-R1: Causes of BAT learning failure

Part Number: BQ28Z610-R1
Other Parts Discussed in Thread: GPCCHEM

Hi Ti

I ask you to analyze the cause of the failure of BAT learning.

- situation

I ran the learning by changing the settings of the PCM that contains the learning data.

In addition, the cell of the pack containing the learning data was removed, and the cell of another manufacturer was attached to perform learning.

This cell does not have a Chem ID. We conducted training to request a Chem ID.


I have attached log and data memory.
