BQ78350-R1: Overload current threshold

Matteo Crida
Prodigy 60 points
Part Number: BQ78350-R1

HI

we've realized a bms with bq76940 an the companion bq78350-r1.

We are trying to record the log files, using bqstudio and EV2300, to send to TI site for the CEDV calculation.

We are making the tests as instruction and we need to sink 3A and 6A from the battery pack, but, over 2A the bms go in protection mode, setting AOLD and AOLDL.

I've not understood what parameters i've to change to increase the threshold of overload (i've already tried to increase OCD current treshold to -10000 mA but the behaviour is the same).

I've also tried to calibrate cc offset and cc gain with bq studio, but at both commands it returns an error "Raw calibration block size returned after command 0xf081 and 0xf082 is an incorrect lenght" ad i don't kow how to calibrate in other ways.

Thanks in advance

Best regards
