Hello team,
Hope you are doing well. Please see below customer question:
We have run into an issue while using the bq76PL455a EVM and need to help to resolve it. The problem we are seeing is that during balancing some of the cell voltage measurements can be off my up to 40mV. This usually impacts BAT1 and adjoining cells to those that are balancing.
This is a fairly significant issue for us. We checked the TI Forum and did not find anything on this issue. We tried changing a number of settings with no success. The EVM is attached to real LiFePO4 cells.
