Hello, I'm working on a custom board where there is the bq27410. I followed all the calibration procedure and I programmed the device with bq evaluation software.
The host system is in charge of sending the "battery present" signal with the command BAT_INSERT at every boot. No BAT_REMOVE command is sent at shutdown because the bq27410 is always connected to the battery and powered even when the system is off.
The battery gauge is SEALED.
After programming with the evaluation software, everything seems to work fine, but at some point the remaining capacity is signaled to zero. To resume the correct functioning I send the following commands: UNSEAL, BAT_REMOVE and BAT_INSERT. This procedure does not always work.
A new programming with the evaluation software, temporary fix the problems.
Someone has an idea of what is going on with my battery gauge? My idea is that sending the BAT_INSERT at every boot is not the correct way to act.
Best regards
Paolo
