I would like to ask the following question (after reading the online response, I still don't understand):
EDV-PACK (bit 2): EDV detection method
1=Based on battery pack
0=Based on battery cells
But in my experience, the behavior of BQ4050 is also the opposite. Configure EDV-PACK="0" to perform PACK based calibration EDV-PACK="1" Perform battery based calibration.
Please refer to the attached screenshot. EDV-PACK="1 uses the lowest voltage of a single cell.", EDV-PACK="0 uses the voltage of the entire battery pack.". I don't know where the problem is. The effect of EDV-PACK is the opposite.
However, the GPC report parameter displays "CEDV parameter generated by FIT. If the EDVV bit is set to 1, when the data is written to flash memory,..." EMF and EDVR0 must be multiplied by the number of serialized cells N“
My project is currently using 4-series 6-parallel, 4-series 8-parallel, and 4-series 11-parallel. May I ask if it is more reasonable to configure EDV-PACK="0" or EDV-PACK="1". Because the protection voltage of the battery pack is also the lowest voltage. The CEDV theory requires the use of the voltage of the battery pack. Due to the lack of power generation balance, there is a significant difference in battery voltage.
When I test GPC data, should I test a single battery cell or only test it in series or parallel?
