Hi,

Good evening,

We are developing 22S BMS for two wheeler application.

1. 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.

The cell 1 measured voltage is 3504mv. The cell 1 OV threshold level is 4195 mV and the LV threshold level is 2509 mV.

Here is my question: why is the register showing fault, the measured voltage is between the boundries line.

please support me how to fix this problem.

 

Note:

This problem is only for cell 1. Other cells are working fine.
