Mr. Thomas,
Please find the attached .senc file.(The file extension is changed to .jpeg, since .senc cant be uploaded, please change the extension, sorry for the trouble)
I am trying to optimize BQ, for a 12V 7500mAH battery. The charger and the load is connected and controlled using a microcontroller and it is an automated process.
The following is my learning process:
1. Without enabling the IT algorithm, I charge the battery, till the current flowing in the battery is less then tapper current and I relax the battery.
2. I clear the update status to 0 so that a new optimization cycle is not affected the previous cycle. Is it a problem? or should i load the value with 4?
3.I enable the IT algorithm, and discharge the battery below 500mV cell voltage and temporarily adjust the cell terminate voltage.
4. Relax the battery and wait until OCV is taken.
5. Charge the battery until inflow current is less then tapper current.
6. relax the battery and wait until OCV is taken.
7. Discharge the battery below 500mv cell voltage.Relax the battery and wait until OCV is taken.
as per the micro controller program, the cycle should continue till update status is 6. But it stays in 4 after a complete cycle.
Please help me to figure out the problem.
