BQ2084-V143: CEDV Data Collection Clarification

BQ4050: CEDV parameter calculator

Part Number: BQ4050
Other Parts Discussed in Thread: GPCCEDV

Hi everyone, 

I have one issue concerning the CEDV parameter process in 'CellTermV'. The battery (2Series) has a set termination voltage of 3.2V=3200mV. However, in the Hightemp_highrate.csv file, the actual termination voltage falls above 3200 mV, which is 3307 mV. My concern is whether I shall use 3200 mV or the actual 3307 mV?

    If your cell termination in the log is higher than the actual terminate voltage used in the parameters, you will be unable to calculate the CEDV paramters with GPCCEDV. I would suggest that you re-test and dsg the cell to slightly below 3.2V for generating your CEDV parameters.
