My problem is the BCC_REG_CELL_OV_FLT_ADDR and BCC_REG_AN_OT_UT_FLT_ADDR values are always 1. That means it is telling the cell voltage OV and LV faults are there in cell 1.</P><P>The cell 1 measured voltage is 3504mv. The cell 1 OV threshold level is 4195 mV and the LV threshold level is 2509 mV.</P><P>Here is my question: why is the register showing fault, the measured voltage is between the boundries line.</P><P>please support me how to fix this problem.</P><P>&nbsp;</P><P>Note:</P><P>This problem is only for cell 1. Other cells are working fine.</P> Thu, 11 Jul 2024 12:49:45 GMT Ramesh123 2024-07-11T12:49:45Z https://community.nxp.com/t5/S32K/BMS-MC33771C/m-p/1906314#M37581 <P>Hi,</P><P>Good evening,</P><P>We are developing 22S BMS for two wheeler application.</P><P>1.
