Other Parts Discussed in Thread: TIDA-00982, BQ24600, , BQSTUDIO, EV2400
Hi all,
We designed a board that looks like tida-00982.
It is based on bq4050 gauge and bq24600 charger.
We use a 2S battery pack with the following characteristics:
- Design capacity: 3000 mAh.
- Design voltage: 7.4 V.
We use bqStudio and EV2400 to setup the bq4050. So we follow the video https://training.ti.com/bq40z50-setup-and-going-production.
We set:
- DA Configuration.
- FET Options.
- Temperature Enable.
- Temperature Mode.
- Enabled Protections A.
- Enabled Protections B.
As follows:
- CUV.
- COV.
- ASCC.
- ASCD.
As follows:
- Power.
- Shutdown.
As follows:
- Low Temp Charging.
- Standard Temp Charging.
- High Temp Charging.
- Rec Temp Charging.
As follows:
- Design.
- TD.
As follows:
When we rich the calibration step, we measure the Cell-1 voltage (3950 mV). And in calibration tab, we check "Calibration Voltage" and press on the "Calibrate Gas Gauge" button.
The result is an error message "Calibration - Cell 1 measured voltage in millivolts is out of range".
Is there any missing setting or configuration ?
Thanks.
