Tool/software:
I am developing a cell-based battery management system (BMS). I’m seeing unexpected voltage readings across the cells. The first cell reads 4V, the second reads 6V, and the last two cells are reading 65V, which is clearly incorrect.
I’d like help diagnosing the issue. Could this be due to incorrect wiring, wrong register configuration, or an issue with cell balancing or ADC calibration?
I'm using the BQ76952 IC for this project. Any guidance or debug steps would be appreciated.
Attached is my schematic
