I am using BQ40z60 having 3 Cells. Cell voltage of each cell is
- 1st cell - 4.1V
- 2nd cell - 3.9V,
- 3rd cell - 2.2V.
Cell Balancing is not happening ( Enabled CB & CBR ).
It is Not charging, Since Cell1 voltage is 4.1v, Once if i apply 15V from adapter start charging in 150mA then goes down TCA bit will set first, RCA also sets next, then FC, VCT, PV bit also sets. Charging goes OFF.
- CUV, CUVC bit set -> due to 2.2V cell
- FC bit sets -> due to 4.2V
How to make cell balance. Externally i can charge and balance and charge. But, Cell Balancing is not happening. Anyone help me to solve this.
Thank you
