Hi,
we are using in our project the BQ27531-G1 to track the remaining capacity of the battery. The battery has a capacity of 4400 mAh. Due to some safety reason we charge with 4.1V (and not 4.2V as required to achieve the full capacity) and I'm just wonder which value to set in the register "Design Capacity". Should I set 4400mAh or another value (i.e. 4200mAh)?
Regards,
Alex
Hi Alex,
If you are performing the learning cycle for the gauge, you should set the design capacity to the battery's nominal capacity (4400mAh). Once the learning cycle has been preformed, the Design Capacity can be changed to the target value for the application.
Below is Section 2.1 from the Achieving the Successful Learning Cycle document:
