Part Number: BQ27542EVM Tool/software: Hi experts, when completed a full charge-discharge cycle, but the cycle count didn't increase. Why?
The gg log data is attached.
Thank you

Part Number: BQ27542EVM Tool/software: Hi experts, The cell cut-off voltage is 3V, the bq27542 termination voltage is set to 3.2V.
What's the risk or side effects when Hibernate voltage set to (default) 2.55V ?
Thank you
Part Number: BQ27542EVM Tool/software: Hi experts,
1. What do chemID max DOD and error mean respectively?
2. If ChemID match max error is Zero, what does it mean?
Thank you.
Part Number: BQ27542EVM Tool/software: Hi Sir,
We have some questions about self-discharge current,
How is self-discharge current generated?
Is there correlation between self-discharge and average discharge current?
Does average…
Part Number: BQ27542EVM Tool/software: Hi Sir,
The BQ27542 has a register called "self-discharge current" that can be used to detect micro shorts in the cell, right? So, how should the self-discharge current value be used?
The BQ27542 has a register…
Part Number: BQ27542EVM Tool/software: Hi experts,
Could we use a real battery instead of a power source when doing current calibration? Are there any side effects?
Thanks
Part Number: BQ27542EVM Tool/software: Hi expert,
we have some question about BQ studio/,BQ27542 board offset calibration vaule: Value: -111 counts =? uA Value: +111 counts =? uA
Thanks
Part Number: BQ27542EVM Tool/software: Hi Sir,
After calibration, what conditions could cause current and temperature errors? The temperature is -20°C, but the internal temperature is 26.5°C. In idle mode, the current is -87xx mA.
Thank you.
Part Number: BQ27542EVM Tool/software: Hi Sir,
At an ambient temperature of 45°C, What is a reasonable value of SOC% error? The battery voltage is 3.77V, the remaining capacity is about 600mAh, the cell capacity is 2830mAh, and the chemID is 3839. …
