Hi, I am using bq76920 for 3 Li-ion Series cell monitoring and balancing. In our system cell balancing is working properly between from 3.5 to 4.2 Volt during charging and discharging but below 3.5 V one of the cells runs out of the race of balancing.
cell 1(volt) | cell2(volt) | cell3(volt) |
4.027 | 4.04 | 4.04 |
3.65 | 3.68 | 3.65 |
3.63 | 3.64 | 3.63 |
3.61 | 3.62 | 3.62 |
3.525 | 3.361 | 3.371 |
3.505 | 3.288 | 3.380 |
