BQ40Z50-R1: Learning cycle

Part Number: BQ40Z50-R1

Hello Steven

with the srec your shared we made a pretty good improvements but still facing few more issue 

We found that charging current fluctuates between 500ma to 1A very frequently (charging through DC regulated power supply).how to resolve this issue.

Some how with the same fluctuating current battery charged fully 5 hours,and kept for discharging with constant load of 10 ohms.we absorb that discharge was perfect and expecting  to set [vok] and [rdis] registers after fully discharged,but this not happened.

Further we try to charge the battery with constant power supply of 4 V and observed battery not getting charged until we send the reset command.

Looking forwards your response. attached the zip files contains snapshot,log and gg files

Regards

  • Hi, Vish

        Please check the voltage of the cell when you see current fluctuating up and down. also please make sure the temperature is measured correctly.

        if the issue persists, please send the log file and gg files logged auto logged and fixed interval.
