Other Parts Discussed in Thread: GPCCHEM, BQ40Z50, BQSTUDIO
Hi Team,
Could you help our cutomer's concern below.
We have developed a battery with the IC BQ28Z610 And have the problem that the remaining capacity calculated by the chip does not match the capacity actually measured. We use LiFePO4 cells with a nominal voltage of 3.2V and 3.6Ah in a 2s2p configuration.
We have already carried out the following points to solve the problem:
- We determined a chemical ID using the "GPCCHEM" tool
- We have carried out learning cycle according to document "slua777_learning_cycle".
Attached is a graph showing the problem.
Thank you so much for your support.
Best regards,
Jonathan
