Hello sir,I am trying to design a 3s BMS. I found some reference, but I dont understand this two portion how they are working. I know how single cell BMS work, But perspective of single cell BMS I am totally unable to understand about the 3s BMS. The right side 1M resistors, Q8,Q7 and Q9 how they are working .

Check out page 9 of this datasheet: https://www.hycontek.com/hy_battery/DS-HY2110_EN.pdfQ7 and Q9 are for the OD and OC outputs.I think that Q8 disables the charge when P- is higher than B-.
