Other Parts Discussed in Thread: BQ40Z80
Hello,
We are following the procedure for the learning cycle and running into some issues.
First, when we start the first discharge, VOK never gets set. Is this supposed to be set prior to discharging our cells or does it not matter? Our RDIS bit never goes low and RELAX bit never goes high, several hours after a full discharge (FD high).
Also, we have a few issues with cell balancing where an individual cell may reach term voltage or full charge, but due to inbalance in the cells, we never reach our pack term voltage or FC (2s, 6000mv). The balancing feature of the BQ40z80 does not appear to be working well, not sure what is causing this but it seems to be affecting our ability to complete the learning cycle (cell V difference is ~300 - 400 mV). Is there a way to fix this or do we have a false expectation of how this should work?
Final thing to note is we have re-started the learning cycle twice due to the above issues, may this be causing problems?
