BQ34Z100-G1: SOC Accuracy

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

Hi,

Could you please help me to know: what the soc accuracy will be expected before a learning cycling (the bq34z100 was programmed with a golden fuel gauge file)?

Thanks,

Joy

The golden file already contains the learned Ra table and Qmax, but the Ra values and Qmax are learned from the specific cells used for learning, when the cell changes, the Ra table and Qmax could also change, so the accuracy can be compromised. The level of the error is determined by how far the key parameters like Ra and Qmax deviate from the sample used for learning cycle.
