Hello,
I have serious problems with BQ34Z100-G1 chip. Actually it is BQ34Z110 upgraded to BQ34Z100-G1 firmware. When I stop charging and turn to relax, then sometimes chip corrupts values of SOC, RM and Full Charge Capacity. Values like Voltage, Current, Temperature and even the Passed Charge are OK, but SOC, RM and FC decreases to 0 % and SOC1 and SOCF flags are set. I have a suspicion, that this is connected to abrupt change of charging current (example 50 A to 6A step).
It is not also possible to achieve Qmax update with Sonnenschein A600 battery and is not possible to go through learning process (optimization cycle).
Thank you for your comments.
