BQ34Z100-R2: Automated Calibration of BQ76942 and BQ34Z100-R2 Without BQStudio

I am looking for a document similar to Host System Calibration Method.

Is there a version of this document that is applicable to the BQ34Z100-R2?

Hi,

If you have 2 EV2400 and 2 instances of BQstudio you can communicate with both devices at the same time.

1) These values are not required. (17) BQ34Z100-G1: How to automate the calibration process? - Power management forum - Power management - TI E2E support forums

2) bq34z100-G1 High Cell Count and High Capacity Applications

Hi Evan,

Both chips are on the same I2C bus, and we cannot disconnect either of them to configure and calibrate the other during production. Therefore, using two EV2400s and two instances of BQ Studio is not an option.

1. Thank you.

2. The High Capacity Application document does not clarify how to calculate the calibration parameters (CC Gain, CC Offset, CC Delta, Board Offset, Temp Offset, and Voltage Divider) or detail the procedure for doing so. The thread you provided concludes that the 'Host System Calibration Protocol' does not apply to the BQ34, and instead, I should refer to the 'Going to Production with the bq34z1xx' document. However, while this document outlines the procedure for the voltage divider, it only mentions taking the average of twenty boards for the other calibration parameters without explaining how to compute these values.

I am looking for guidance similar to the 'Host System Calibration Method' but specifically for the BQ34.

Hi,

2) Sorry about that I linked the wrong thread, this one should help - (+) BQ34Z100-G1: Commands for calibration procedure - Power management forum - Power management - TI E2E support forums

Hi Linus,

I am not sure what you mean by the measurements are unique, there is no counter for the measurements.

Are you using BQstudio to calibrate your device?
