Good morning all,
Our 3S1P Li-ion battery pack is built around a BMS+charger PCB that uses BQ20Z65 as gas gauge and BQ24765 as charge controller.
We set the CHGLED=1 so that during the charging phase the LEDs show the charge level and highest charge level LED is blinking.
Once the battery has reached the fully charged state the LEDs turn OFF even if the battery pack is still connected to the Ac adapter.
Our customer is asking to have the LEDs stay ON once the battery pack has reached the fully charged state and it is still connected to the AC adapter.
We went through the BQ20Z65 technical reference but it doesn't seem it is possible. Is it possible to modify the BQ20Z65 firmware to implement this?
Many thanks in advance for your help
Best Regards,
Walter Castagna
