Tool/software:
hi team
my customer is using BQ34Z100 and they found that the fuel gauge current performs automatic current calibration in standby and shutdown modes, and probabilistic correction of the sample current, resulting in SOC bias
We look forward to receiving a response with the following questions:
1. How does the automatic current calibration function turn off?What are the three parameters ? Is it completely independent of the above bus low time and deadband
2. The current auto-calibration function is mentioned in the reference manual in: Before sleep is performed; meeting I2C Bus Low Time and VSR larger than Deadband is also performed; how to avoid entering auto-calibration in both scenarios
3. By increasing the deadband value, can avoid the above two scenarios enter the current automatic calibration, are there other risks?
4. When self-calibration is carried out, there will be internal short circuit Snr/snp, we in the process of use, the individual chip has a calibration deviation, Is there a possibility of a short circuit impedance anomaly, has there been a previous case of the same? Is there any way to verify this?
