Hello I'm newbie to BMS, sorry !
I have designed a portable audio product in which I use a raspberry Pi.
Right now I'm using on the shelf BMS board but I'm not pleased with the results.
I'm using LiFePO4 4S1P batteries and I would like to address different issues:
- Battery pack Charge/Discharge managment
- Ability to use the system with and without the external PSU
- Basic report of the battery pack level (very basic gauge, with a dual led : Green, Orange, Red, the LEDs could be under the Pi's GPIO control)
- Proper shut down of the Raspberry Pi when the battery pack is discharged (link to point 3)
I have found the BQ24773 that looks fine for this.
However I have no clue on how to make all my requests to work...
Do you confirm that BQ24773 is suitable for my needs ?
How can I get the basic status of the battery level through the I2C bus ? Do I need to add another circuit ?
ANY Schematic for my needs ?
Thank you very much for your help !
Jean
