Hi Everyone,
I have two 4 cell packs that seem to have the same issue wherein there is a permanent failure CIM_A that I cannot clear. my CIM_config is as follows:
Active CIM Fail Voltage = 800mV
Active CIM Time = 5s
Active CIM Check Voltage = 3075mV
I am able to clear it momentarily but it returns in about 1 second (faster than I am reading the register) and other permanent failures disappear just fine.
The current cell voltages in one pack are 2468, 2445, 2445, 2468mV; which while low are reasonable well balanced. I am trying to charge the battery but am unable to because of the permanent failure.
Has anyone else seen this issue or a similar one where a ghost PF flag is set?
I imagine it is something wrong with my data flash but I can't figure out what and cannot change anything because of my state of charge and PF flag.
Thanks, David
